Problems solved by technology

[0013] Obviously, this kind of regenerative furnace operation control is relatively rough and primitive, and cannot accurately predict the required heat supply
Each section corresponds to a certain temperature range, that is, corresponds to different required heat supply, but they all adopt the same operation strategy, so the best economic operation cannot be achieved

Abstract

This invention discloses a heat supply prediction and control method for a heat storage boiler system, among which, the prediction method means actually testing operational heat load and adding the modified factor of atmospheric temperature, the control method computes the necessary heat value of each time section according to the heat load chart predicted by the prediction method to control its work on the principle of fully using valley electricity, seldom using normal and not using peak.

Description

technical field [0001] The invention relates to heat supply prediction and control methods of a heat storage boiler system, in particular to a heat supply prediction and operation heat supply method of a heat storage boiler used for heat storage with water in a time-sharing power grid. Background technique [0002] The pressure heat storage electric boiler uses water to store heat. There is a steam chamber on the top of the heat storage tank, and a hot water storage chamber below it. There are several groups of electric heating tubes in the hot water storage chamber of the regenerative furnace. Using the cheap off-peak electricity at night, the electric heating tubes are energized and the hot water is heated. With the progress of the heating process, the pressure of the steam chamber gradually increases, so the temperature of the stored hot water also gradually rises. The maximum water temperature of the existing pressurized thermal storage electric boiler is 145°C, and the...
