Problems solved by technology

Although this method mentions the evaluation of the blended combustion effect from the perspective of combustion efficiency, it does not specifically explain how to calculate the combustion efficiency, nor does it consider the blended combustion effect from the perspective of environmental protection operation, and the economic and environmental indicators are just the current thermal power plants most important aspect
[0007] Traditionally, the characterization of boiler performance is usually judged by boiler efficiency. With the emphasis on environmental protection indicators in various countries, pollutant emission data has also become an important parameter of boiler performance; The output of auxiliary machines such as fans is increased, and the quality of coal blending is poor, resulting in boiler slagging, etc., which will lead to boiler safety problems; therefore, the evaluation of coal blending results should comprehensively focus on boiler safety, economy and environmental protection sex

Embodiment 1

[0091] Such as figure 1 , 2As shown, step 1000 is executed, and the data acquisition module 200 automatically collects relevant index data synchronously, and the relevant index data includes boiler combustion result data, various index data of furnace coal, and at least one data of power generation. Relevant index data can be divided into two categories, including at least one type of data among basic parameters and effect parameters. The basic parameters are input parameters, which refer to the parameters that have a decisive impact on the operation mode of the unit and the safe, economical and environmentally friendly operation of the unit. Once the basic parameters change, the unit operation mode must be adjusted accordingly to adapt to this change, generally including load , Coal. The effect parameters, that is, the output parameters, are the parameters that characterize the operation of the unit. These parameters are not adjustable and are the response of the boiler com...

Embodiment 2

[0104] According to the evaluation of the plan and the relevant index data collected automatically, the system generates an evaluation analysis report, which is convenient for providing optimization feedback suggestions for fuel management, and provides specific and targeted guidance.

[0105] The system collects SIS system data synchronously in real time, combines the real-time mixed combustion situation of the unit and the combustion performance feedback data, establishes a database of mixed combustion and operation, adopts the big data mining technology based on case library optimization, and mines the conditions of the unit under different loads and different coal types. the best mode of operation.

[0106] Based on the dynamic monitoring function of the coal bunker mentioned above, the system will automatically count the operation cycle of each coal type grinded by each coal mill, and provide reference for the regular replacement of coal types. After the machine grinding ...

Abstract

The invention provides a method and system for evaluating coal blending and blending combustion, wherein the method includes synchronously and automatically collecting relevant index data, and further includes the following steps: establishing a blending burning database and an operation database; according to the related index data in the blending burning database , to evaluate the plan and implementation of blending. The present invention provides an evaluation method for blending coal blending, which establishes a calculation model based on the coal quality information of the furnace and the boiler combustion effect under different loads, and evaluates the blending plan, so as to help thermal power enterprises find safety, economy, and environmental protection effects The best coal blending and burning scheme.

Description

technical field [0001] The invention relates to the field of fuel management, in particular to a coal blending and blending evaluation method and system. Background technique [0002] Fuel cost is the most important operating cost in the production and operation of thermal power plants or units. Coal consumption for power supply reflects the energy efficiency level of a thermal power plant or a unit. It is usually a relatively stable value under the condition of stable incoming coal quality. Subject to the influence of supply and demand in the coal market, the price difference of fuel purchased from different coal mines is A variable that fluctuates in real time makes the operating costs of thermal power plants vary greatly under different coal blending ratios, which is also the fundamental motivation for coal blending in thermal power plants. [0003] At present, boilers in thermal power plants are selected according to the corresponding design coal type. When the coal qua...
