The invention discloses a system and method for determining the optimal heat source of a multi-heat source heater under variable working conditions, adopting a thermal test and a single variable comparison method to determine the coal consumption of a coal-fired power unit under a given condition of power supply load and ambient air temperature The minimum is the optimization objective function, and the boiler thermal efficiency, steam turbine heat consumption rate and substation power consumption rate test are carried out for each heat source scheme under different inlet air temperature conditions of the air preheater. Then compare the lowest value of coal consumption for power supply of each heat source scheme, and take the lowest value as the optimal heat source and the optimal value of air temperature at the inlet of the air preheater under the given conditions of power supply load and ambient temperature. In the present invention, the coal power unit power supply coal consumption is the lowest under the condition of constant power supply load and ambient air temperature as the optimization objective function, and the boiler heating value of the coal power unit equipped with multi-heat source heaters under different boundary conditions such as boiler power supply load and ambient air temperature is obtained. The optimal heat source scheme of the fan and the optimal value of the air temperature at the inlet of the air preheater to achieve the lowest operating cost.
Description
technical field [0001] The invention belongs to the technical field of energy saving and consumption reduction, and relates to a system and method for determining an optimum heat source under variable working conditions of a multi-heat source fan heater. Background technique [0002] Coal-fired boilers in power plants are usually equipped with air heaters to avoid the harm of low-temperature corrosion on the rear heating surface. The heater is arranged in the air duct from the outlet of the primary fan (including the blower) to the inlet of the air preheater. The heating season in some areas is cold and lasts for a long time. The normal operation of the heater plays a vital role in supporting the safe and stable operation of the cogeneration unit and the protection of social and people's livelihood. According to the form of heat source, air heaters can be divided into steam heaters and hot air heaters. Among them, steam heaters are the standard configuration for the design ...
