Description

Technical Field

[0001] This invention relates to the field of ship energy conservation and automation control, and in particular to an auxiliary heating system and control method for oil tankers. Background Technology

[0002] When large vessels such as oil tankers and chemical tankers are berthed in port (excluding non-operational conditions such as unloading, tank cleaning, and inertia filling), a fuel-fired auxiliary boiler is traditionally required to operate continuously to ensure that the ship's power plant (main engine) can be started at any time and that the viscosity of the fuel required for combustion by the generator set (auxiliary engine) is qualified. This auxiliary boiler generates steam, which is circulated and kept warm in the main engine cylinder liner water circuit through a steam heater, and also heats the fuel in the fuel supply unit.

[0003] However, this traditional model suffers from significant energy waste and operational drawbacks: First, the auxiliary boiler itself consumes a huge amount of fuel oil (typically 2-3 tons per day), and its operation requires a series of auxiliary equipment such as boiler fans, feedwater pumps, and fuel oil pumps, resulting in additional electricity consumption. Second, to dissipate the heat generated by the boiler operation and engine room equipment, more high-power engine room fans must be turned on, creating a vicious cycle of "energy consumption for cooling." In total, the daily energy consumption of a large oil tanker while at berth can reach over 5 tons of fuel oil equivalent. This directly leads to high ship operating costs and generates large amounts of carbon dioxide, sulfur oxides, and nitrogen oxides emissions, posing a serious challenge to the global shipping industry's Energy Efficiency Index (EEXI) and Carbon Intensity Index (CII) assessments.

[0004] Therefore, there is an urgent need for a new system and control method that can significantly reduce or even eliminate the need for auxiliary boiler operation during berthing, while ensuring the absolute safety of the ship and its readiness to sail at any time. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an auxiliary heating system and control method for marine tankers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Auxiliary heating systems for marine tankers include:

[0008] The signal acquisition module is used to acquire operating condition signals in real time, including main engine speed, main engine status, cylinder liner water temperature, fuel oil temperature, steam pressure, fuel oil tank level and boiler status.

[0009] The execution drive module includes a cylinder liner water heating submodule and a fuel heating submodule. The cylinder liner water heating submodule consists of an electric heater and a circulating pump and is connected to the main engine cylinder liner water circuit to form an independent small circulation. The fuel heating submodule consists of a fuel electric heater and an automatic switching valve group and is connected in parallel with the original steam heater to the fuel supply unit.

[0010] The control decision module is electrically connected to the signal acquisition module and the execution drive module respectively. It stores an intelligent control program, which is used to send control commands to the execution drive module based on the working condition signal and according to the preset control logic and algorithm. The control logic includes the parking mode, the navigation mode and the switching logic between them.

[0011] Human-computer interaction module, which is used for parameter setting and status display;

[0012] A security protection module is used to perform hardware protection actions in the event of a system failure.

[0013] Preferably, the intelligent control method implemented in the control decision module includes the following steps:

[0014] The main engine status is checked, and when it is determined that the vessel has entered a berthing preparation state, the fuel reserve confirmation procedure is executed.

[0015] After the main unit confirms the shutdown, it enters the parking operation phase, starts the circulation pump of the cylinder liner water heating submodule, and adjusts the power of its electric heater based on the cylinder liner water temperature using a closed-loop control algorithm to maintain the cylinder liner water temperature within the set range.

[0016] At the same time, the automatic switching valve group controls the fuel flow path to the fuel electric heater, and adjusts the power of the electric heater based on the fuel temperature. During this stage, the auxiliary boiler and its auxiliary equipment are kept off, and the auxiliary boiler is only started periodically for short-term heat preservation operation.

[0017] When the host engine is detected to be ready or start, the departure switching phase begins. First, the cylinder liner water heating submodule is gradually shut down as the host engine runs. Then, the steam pressure is monitored. When the steam pressure stabilizes and reaches the threshold, the automatic switching valve group is controlled to switch the fuel flow path back to the steam heater and shut down the fuel electric heater, completing the switch from electric heating mode to steam heating mode.

[0018] Preferably, the closed-loop control algorithm for the cylinder liner water temperature is a PID (Discrete-Induced Pulse Control) algorithm, and the mathematical expression of its discretized control law is: ,in:

[0019] u(k) is the output of the controller at the kth sampling time, corresponding to the power control command for the cylinder liner water heater;

[0020] , which represents the cylinder liner water temperature deviation at the k-th sampling time. The preset target temperature for the cylinder liner water. The actual temperature of the cylinder liner water collected by the first temperature sensor at the k-th sampling time;

[0021] These are the pre-tuned proportional coefficient, integral coefficient, and differential coefficient;

[0022] The sampling period of the control system;

[0023] k and j are the sampling sequence indexes;

[0024] The control decision module dynamically adjusts the working state or power of the cylinder liner water heater by calculating the output u(k) in real time.

[0025] Preferably, the logic for periodically starting the auxiliary boiler for short-term heat preservation is as follows: during the continuous time period T of the shutdown operation phase... total Within, control the total operating time t of the auxiliary boiler. boiler Satisfy t boiler < 0.01 * T total And the duration of a single heat preservation operation is t burst Satisfying 5 minutes ≤ t burst ≤30 minutes, the interval t between two consecutive heat preservation operations interval Satisfying 24 hours ≤ t interval ≤ 72 hours.

[0026] Preferably, the fuel electric heater in the fuel heating submodule adopts graded power control or pulse width modulation control. Its power level or duty cycle is dynamically adjusted according to the fuel viscosity-temperature characteristic curve and the real-time collected fuel outlet temperature. The adjustment is based on querying a preset viscosity-temperature-power mapping table or through a PID control loop with viscosity as an intermediate variable.

[0027] Preferably, the safety protection module includes an independent hardware safety circuit that directly monitors the surface temperature of the electric heater, the flow switch signals of the cylinder liner water and fuel circuits, and the status of the electrical circuit breaker and thermal relay. When an over-temperature, low flow, or overload fault is detected, the hardware safety circuit can bypass the control decision module, directly cut off the power supply to the electric heater, and simultaneously send a fault-safe position command to the automatic switching valve group to force it to switch to the steam heating side, while triggering the highest level of audible and visual alarm.

[0028] Preferably, the system also includes an energy efficiency assessment and communication module, which is used to record and calculate the cumulative fuel savings, energy efficiency, carbon emission reduction, and operating hours and energy consumption of each major piece of equipment during system operation. The energy efficiency assessment and communication module is equipped with a wired or wireless communication interface for periodically uploading energy efficiency data and equipment status data to the shore-based monitoring center, or receiving optimized control parameters from the shore-based monitoring center.

[0029] The auxiliary heating control method for marine tankers includes the following steps:

[0030] S1: Parking Mode Entry and Preparation:

[0031] Receive and process ship operating condition signals from the signal acquisition module. When the ship is determined to be in berthing preparation state based on the operating condition signals, confirm the fuel reserve and activate the auxiliary heating system to enter the berthing operation mode.

[0032] S2: Main engine cylinder liner water polishing for temperature control:

[0033] In the parking operation mode, when it is confirmed that the main unit is in a stopped state, a small power circulation pump connected to the main unit cylinder liner water circuit is started to establish a small circulation of cylinder liner water.

[0034] Based on the real-time feedback of the cylinder liner water temperature from the signal acquisition module, a closed-loop control algorithm is used to calculate and output a control quantity to adjust the power of an electric heater set in the small circulation loop of the cylinder liner water, so as to maintain the cylinder liner water temperature within the preset target temperature range.

[0035] S3: Oil-fired heating and auxiliary boiler dormancy management:

[0036] In the parking operation mode, the automatic switching valve group set in the fuel supply unit controls the fuel flow path to switch to the fuel electric heater.

[0037] Based on the real-time feedback of fuel temperature from the signal acquisition module, the output power of the fuel electric heater is adjusted to ensure that the fuel viscosity meets the combustion requirements of the auxiliary engine.

[0038] During this period, the ship's auxiliary boilers and their auxiliary equipment are kept off, and heat preservation ignition commands are sent to the auxiliary boilers only periodically for a duration much shorter than the berthing time.

[0039] S4: Departure Mode Heat Source Switching:

[0040] When a host standby command is received or a host start signal is detected, the departure switching mode is entered.

[0041] Gradually shut down the cylinder liner water heater and the low-power circulating pump;

[0042] Monitor the steam pressure generated by the exhaust gas boiler or combined boiler. When the steam pressure continuously reaches and exceeds the stable pressure threshold, control the automatic switching valve group to switch the fuel flow path from the fuel electric heater back to the original steam heater. Then, turn off the fuel electric heater to complete the switch from electric heating mode to steam heating mode.

[0043] An electronic device includes a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the steps of an auxiliary heating control method based on a marine tanker.

[0044] A computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of an auxiliary heating control method for marine tankers.

[0045] The beneficial effects of this invention are as follows:

[0046] This invention combines the main scheme of "electric heating replacing steam heating" with the auxiliary scheme of "periodic short-term maintenance operation of auxiliary boilers," and is equipped with an intelligent multi-modal switching control strategy. Under the core premise of ensuring absolute ship safety, equipment integrity, and readiness for sailing at any time, it reduces the operating time of auxiliary boilers during the ship's stay at sea for several days, improves the overall energy saving rate, reduces operating costs, maintenance expenses, and pollutant emissions, and effectively improves the ship's Energy Efficiency Index (EEXI) and Carbon Intensity Index (CII) rating.
