Document Type and Number:
WIPO Patent Application WO/2023/165181
Kind Code:
A1
Abstract:
A steam generation control method, applied to a steam generation system. The steam generation system comprises a liquid inlet (1), a steam outlet (2), and a liquid pump (3), a water inlet valve (4), and a steam heater (5) connected between the liquid inlet (1) and the steam outlet (2); the water inlet valve (4) is connected between the liquid inlet (1) and the steam heater (5). The control method comprises: S1, controlling the liquid pump (3) to operate so as to drive a liquid to be conveyed from the liquid inlet (1) through the water inlet valve (4) to the steam heater (5) in a heating state; and S2, during operation of the liquid pump (3), controlling the water inlet valve (4) to be turned on and turned off alternately at a preset frequency for operation, so that the liquid intermittently passes through the water inlet valve (4), and the liquid passing through the water inlet valve (4) is conveyed into the steam heater (5) in the form of pulsed water flows. Each pulsed water flow continuously flows in the steam heater (5) and is at least partially evaporated and vaporized before flowing out of the steam heater (5). By means of the steam generation control method, steam which is continuous and has stable quality can be generated.
