Low-temperature economizer energy saving amount optimization method, device and equipment and storage medium

Abstract

The invention discloses a low-temperature economizer energy saving amount optimization method which comprises the steps that S1, pre-disturbance preset operation parameters of a current low-temperature economizer during operation under the current working condition are obtained, and the first energy saving amount of the current low-temperature economizer is calculated according to the pre-disturbance preset operation parameters; s2, disturbance is applied to a preset variable of the current low-temperature economizer; s3, post-disturbance preset operation parameters of the current low-temperature economizer during operation under the current working condition are obtained, and a second energy saving amount of the current low-temperature economizer is calculated according to the post-disturbance preset operation parameters; s4, whether a result of a preset relational expression of the first energy-saving amount and the second energy-saving amount meets a preset range or not is judged; and S5, if not, he second energy-saving amount is taken as the first energy-saving amount, and then the steps S2 to S4 are repeatedly executed until the result of the preset relational expression meetsthe preset range. According to the optimization method, the energy saving amount of the low-temperature coal economizer can be optimal. The invention further discloses a low-temperature economizer energy saving amount optimization device and equipment and a storage medium.

Description

technical field [0001] The invention relates to the technical field of boiler energy saving, and more specifically relates to a low-temperature economizer energy saving optimization method, device, equipment and storage medium. Background technique [0002] As we all know, during the operation of the boiler, the exhaust gas loss is the main heat loss of the boiler. The higher the exhaust gas temperature, the greater the heat loss of the exhaust gas, and the greater the corresponding coal consumption. Therefore, in order to reduce the exhaust gas temperature and save energy, now A thermal power plant usually installs a low-temperature low-temperature economizer on the boiler to use condensed water to absorb the heat of the exhaust gas in the low-temperature low-temperature economizer, reduce the temperature of the exhaust gas, and then return to the steam turbine for low-pressure heating after being heated by itself. The heater system replaces the role of part of the low-pres...
