[0033] The present invention will be described clearly and completely below with reference to the accompanying drawings and embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, not all embodiments.

[0034] See also Figure 1 The comprehensive economic benefit evaluation method of the sludge co-incineration transformation project of the present invention comprises the following steps:

[0035] Step 1: Data collection and organization. The data includes project investment cost data, operating cost data, and revenue data. The details of each data are as follows:

[0036] 1.1 Project investment cost data. Project investment cost data includes equipment purchase costs, equipment installation and commissioning costs, site renovation costs, and equipment depreciation costs. The details of each cost are as follows:

[0037] Detailed statistics are made on the equipment purchase costs of the sludge co-incineration modification project. The equipment purchase costs include, but are not limited to, equipment specifically used for sludge treatment (including sludge dryers, sludge conveying equipment), and components required for adaptive modification of existing coal-fired power generation equipment (including boiler burner modification components, flue gas treatment system upgrade equipment). In addition, the equipment installation and commissioning costs include labor costs (including labor costs for different technical types of work), material costs (including various metal materials and connecting parts required for installation), and consumables costs during the commissioning process (including chemical reagents used for testing and standard parts for calibration instruments). Site modification costs include the expansion costs of the storage yard (including land purchase or lease costs, site leveling and infrastructure costs), and the modification costs of the conveying system (including pipeline laying, conveyor belt replacement or upgrades). At the same time, considering the service life of the equipment, the annual equipment depreciation costs are calculated according to a reasonable depreciation method and included in the investment cost data.

[0038] 1.2 Operating cost data, including fuel costs, equipment maintenance costs, labor costs, water and electricity costs, and environmental protection treatment agent costs. The details of each cost are as follows:

[0039] Continuously monitor and record fuel costs, separately count the consumption of coal and sludge (obtain accurate data through fuel metering equipment), and the price fluctuations of coal and sludge (such as based on market purchase prices or long-term supply contract prices). Equipment maintenance costs are classified and counted according to different equipment types, including regular maintenance costs (such as regular replacement of equipment lubricants, cleaning filters, and other required material and labor costs), parts replacement costs (calculated based on the replacement cycle and market prices of equipment wearing parts), and overhaul costs (estimated based on the equipment's service life and maintenance plan). Human resource costs comprehensively consider the salaries of various types of personnel required for the project (salary levels for different positions), benefits (such as social security, medical insurance, housing subsidies), and training costs (such as new employee induction training and technical personnel skills improvement training). In addition, operating costs such as water and electricity charges and environmental protection treatment agent costs during operation must also be considered.

[0040] 1.3 Revenue data, including power generation revenue, sludge treatment costs, by-product sales revenue and policy subsidy data. The details of each cost are as follows:

[0041] Accurately calculate the power generation income based on the electricity market price and the actual power generation of the project (measured by the power plant meter). The cost savings of sludge treatment are obtained by comparing the cost difference of traditional sludge treatment methods (such as landfill and separate incineration) and sludge co-incineration. In terms of by-product sales revenue, if the sludge co-incineration process produces saleable by-products (such as ash used for building materials production), the output and market sales price are counted to calculate the revenue. Policy subsidy data collects various subsidy policies of the national and local governments for sludge co-incineration projects, including construction subsidies (calculated according to the project construction scale and subsidy standards), operation subsidies (determined according to the operating time and subsidy amount), and environmental protection compliance subsidies (based on environmental monitoring data and subsidy policy regulations).

[0042] Step 2: Establish an economic benefit evaluation indicator system. The economic benefit evaluation indicators include net present value, internal rate of return, and payback period. The situation of each indicator is described as follows:

[0043] 2.1 The details of Net Present Value (NPV) are as follows:

[0044] Determine the calculation period, refer to the life cycle of similar projects or determine it according to the specific plan of the project. The calculation period is generally 10-30 years. Forecast the net cash flow of each year. Net cash flow = cash inflow - cash outflow. Among them, cash inflow includes power generation income, sludge treatment cost savings, by-product sales income and policy subsidies. Cash outflow includes project investment cost (calculated by equipment depreciation and loan interest on an annual basis) and operating cost. Choose a suitable discount rate, refer to the industry average return on investment, bank loan interest rate, opportunity cost of funds and other factors, and then use the formula Calculate the net present value, where NCF t is the net cash flow in year t, i is the discount rate, and n is the calculation period.

[0045] 2.2 The details of the internal rate of return (IRR) are as follows:

[0046] The internal rate of return is calculated by iterative method or using professional financial software. The discount rate when the net present value is equal to zero is the internal rate of return. The calculation formula of internal rate of return (IRR) is Among them, NCF t Same meaning as n.

[0047] 2.3 The details of the payback period (PP) are as follows:

[0048] From the start of investment in the sludge co-incineration renovation project, the cumulative net cash flow is calculated year by year. When the cumulative net cash flow is greater than or equal to zero for the first time, the corresponding year is the investment payback period. If the cumulative net cash flow is negative in one year and becomes positive in the next year, the investment payback period can be calculated using linear interpolation. The calculation formula for the investment payback period (PP) is: Where m is the year when the cumulative net cash flow is last negative, C is the absolute value of the cumulative net cash flow in the mth year, and NDF m+1 is the net cash flow in year m+1.

[0049] Step 3, sensitivity analysis, specifically includes the following processes:

[0050] Determine the sensitivity factors, which include sludge co-combustion ratio, coal price, equipment maintenance cost, policy subsidy amount and sludge moisture content.

[0051] While other sensitivity factors remain unchanged, each sensitivity factor is changed separately (even if a sensitivity factor is changed, other sensitivity factors (i.e., the sensitivity factors other than the aforementioned sensitivity factor) remain unchanged). The range of change of the sensitivity factor can be set to: ±5%, ±10%, ±15%, etc. Calculate the economic benefit evaluation indicators (NPV, IRR, PP) under the change of each sensitivity factor, analyze the trend and degree of change of the indicators with the sensitivity factors, and draw sensitivity analysis charts (such as line charts and bar charts). The use of sensitivity analysis charts can intuitively show the degree of influence of each factor on economic benefits and provide a reference for project decision-making. For example, when the sludge blending ratio is increased by 10%, analyze the impact on the net present value (NPV), internal rate of return (IRR), and payback period (PP), observe how these indicators change, and thus determine the sensitivity of the sludge blending ratio to the project's economic benefits.

[0052] Step 4, scenario analysis, includes the following steps:

[0053] Different scenarios are set based on sensitivity factors, such as an optimistic scenario (assuming a significant increase in sludge treatment subsidies, a decrease in coal prices, high equipment operation stability and low maintenance costs, and a stable sludge moisture content), a neutral scenario (conventional forecasts based on current market and technical conditions), and a pessimistic scenario (such as the cancellation of subsidy policies, a significant increase in coal prices, frequent equipment failures, and large fluctuations in sludge moisture content).

[0054] For each scenario, the economic benefit evaluation indicators were recalculated based on the conditions set for each scenario, and the project economic benefits under different scenarios were compared to assess the feasibility and risk level of the project under different market and policy environments. For example, in an optimistic scenario, assuming that the sludge treatment subsidy increases by 20% annually over the next five years and the coal price decreases by 10%, the project's net present value, internal rate of return, and payback period were recalculated to determine whether the economic benefits of the sludge co-incineration renovation project would be significantly improved under this ideal situation. In a pessimistic scenario, assuming that the subsidy policy is completely eliminated in the third year and the coal price increases by 30%, the project's economic benefits would be analyzed to determine whether it can still remain profitable or within an acceptable loss range.

[0055] Example

[0056] The comprehensive economic benefit evaluation method of the sludge co-incineration transformation project in this embodiment includes the following steps:

[0057] Step 1: In an actual sludge co-incineration modification project, detailed records of all expenses and revenues from project planning to operation were first collected and collated according to data collection and organization requirements. For example, when collecting project investment cost data, accurate statistics were collected for the purchase of the sludge drying equipment, including the equipment price, transportation costs, and labor and material costs during installation and commissioning. Annual depreciation was calculated based on the equipment's estimated lifespan and depreciation method, and included in the investment cost. Regarding operating cost data, metering equipment installed in the coal pipeline and sludge feed system monitored fuel consumption in real time, and fuel costs were recorded based on market price fluctuations. Furthermore, detailed records were kept of all equipment maintenance costs, including material and labor costs for regular maintenance, actual costs for parts replacement, and estimated overhaul costs based on the equipment overhaul plan. Regarding labor costs, accurate statistics were collected for salaries, benefits, and training costs for personnel in different positions. Furthermore, operating cost data, including utility bills and environmental treatment agent costs, was also required.

[0058] Step 2: When establishing an economic benefit evaluation indicator system, calculate the net present value based on the project's estimated 20-year life cycle (including a 2-year construction period). When forecasting net cash flow, consider that the power generation efficiency may be low in the initial stage of project operation, and gradually improve with equipment running-in and technical optimization, and reasonably estimate the power generation and corresponding income in each year. The discount rate is determined to be 10% with reference to the return on investment of similar projects in the same industry. The internal rate of return is calculated iteratively using professional financial software. The payback period is calculated based on the cumulative net cash flow year by year. During the calculation process, it was found that the cumulative net cash flow of the project was greater than zero for the first time in the 8th year, and the payback period was accurately calculated using linear interpolation.

[0059] Step 3: When conducting a sensitivity analysis, the sludge co-incineration ratio, coal price, equipment maintenance costs, policy subsidy amount, and sludge moisture content were selected as sensitivity factors. When the sludge co-incineration ratio increased by 5%, the various economic benefit indicators were recalculated, revealing a 15% increase in net present value, a 3 percentage point increase in internal rate of return, and a 1.2-year reduction in payback period. Similar calculations were performed to determine the impact of changes in other factors on the indicators, and sensitivity analysis charts were drawn to visually demonstrate the sensitivity of each factor. For example, when the sludge moisture content increased by 10%, the project's net present value decreased by 8%, the internal rate of return decreased by 2 percentage points, and the payback period increased by 1.5 years. This indicates that sludge moisture content also has a certain impact on the project's economic benefits, requiring attention and control during project implementation.

[0060] In step 4, the scenario analysis assumes an optimistic scenario in which sludge treatment subsidies increase by 10% annually over the next five years, coal prices decrease by 15%, sludge moisture content stabilizes at a low level, equipment operates stably, and maintenance costs are low. In the pessimistic scenario, the subsidy policy is eliminated in the third year, coal prices increase by 20%, sludge moisture content fluctuates significantly, and equipment failures frequently occur. Economic benefit indicators were recalculated for each scenario. The results show that the project's net present value (NPV) significantly increases under the optimistic scenario, shortening the payback period to six years; while the pessimistic scenario turns negative, extending the payback period to over 12 years. Scenario analysis provides benefit forecasts and risk assessments for project decision-making under different market and policy environments. For example, under the optimistic scenario, the project has high economic benefits and a short payback period, arguably leading to considerations for increased investment or further optimization of the project's scope. Under the pessimistic scenario, the project faces significant risks, necessitating the development of preemptive strategies, such as exploring alternative fuels or reducing operating costs, to ensure project feasibility.
