Definitions
- the circulating pump is started to store the heat.
- the molten salt at the bottom of the tank is sent to the top of the heat storage tank, so that the high-temperature molten salt moves down layer by layer to meet the demand of the steam outlet temperature.
- the molten salt has a wide working temperature range and a large heat storage capacity.
- the water output from the water inlet pipe 12 enters the heater 7 through the third flow regulating valve 20 and is heated into steam, and then leads to the user side through the water spray desuperheater 10 and the steam pipe 13, and is detected by the third thermometer 9
- the temperature of the steam in the steam pipe 13 when the temperature of the steam in the steam pipe 13 is higher than the preset maximum steam temperature value, the first regulating valve 14 is opened, and the water in the water inlet pipe 12 is sprayed into the water spray desuperheater 10
- the second regulating valve 15 is opened, and the circulating pump is started.
