Abstract

The invention provides a power station energy storing and heating peak valley adjusting system. The system comprises a deoxidizing device, a deoxidizing water tank, a deoxidizing device water supply pipeline, a water tank water supply pipeline, a by-pass adjusting pipeline, a steam balancing pipeline and a steam supplementing pipeline. The deoxidizing device is located at a high position. The lower end of the deoxidizing device is connected with the deoxidizing device water supply pipeline which is used for supplying water to a boiler. The upper end of the deoxidizing device is connected withthe steam balancing pipeline. The steam balancing pipeline is connected with the deoxidizing water tank and the steam supplementing pipeline. The steam supplementing pipeline is connected to a heatingfemale pipe. The deoxidizing water tank is located at the low position. The deoxidizing water tank comprises a tank body. A gas input valve is arranged at the upper end of the tank body and is connected with the steam balancing pipeline. A water supply valve is arranged at the lower end of the tank body. A hot water pump is connected to the water supply valve. The system has the advantages of being stable in operation, high in heating ability, high in energy source utilization rate, safe and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of power stations, in particular to an energy storage and heat supply system of a power station. Background technique [0002] Due to the development of society and the implementation of various policies for energy conservation and emission reduction in my country, cogeneration of thermal power plants has become the only production method for central heating. In order to further improve thermal efficiency, the steam extraction units of most thermal power plants are further replaced by back pressure units, and many thermal power plants have completely stopped using peak-shaving steam extraction units, and the heat supply is completely completed by back pressure units and double reduction. . [0003] However, the heat load in most heating districts is unstable. Their characteristic is that 8:00 am to 11:00 am is the peak time (the maximum heat consumption period of the day), and 23:00 pm to 6:00 the next day...
