Water.
The operating pressure in boiler is set according to the transformation temperature of phase-change material in heat-storing sphere in heat-accumulating process, it is higher than transformation temperature
The saturation pressure of 2 DEG C to 5 DEG C of the corresponding vapor of temperature spot is used as the operating pressure in boiler.Supervised by pressure sensor 13
Pressure in the pressure surveyed in boiler, the heating power control boiler of control electric heater 1, makes pressure maintain setting value.With
The power of track Stress control electric heater, ensures that pot in-furnace temperature is in setting operating mode in heating process, it is to avoid high pressure occur and make
Into accident.If adjusting the operating mode of boiler, it can be achieved with by pressure setting.The operating pressure of boiler must be not more than boiler
Design allow operating pressure.
Present invention also offers the detection method of the incoagulable gas of the heat accumulating type electric boiler, its Method And Principle：Do not having
In the case of incoagulable gas, the corresponding saturation temperature of pressure correspondence that saturation water steams, if there is incoagulable gas in system,
The pressure of actual measurement is more than corresponding saturation pressure under saturation temperature.The steam temperature that can be measured by thermocouple, Jin Erke
To calculate corresponding saturation pressure, the pressure in boiler can be surveyed by pressure sensor, two pressure are compared, so that it may
Whether there is incoagulable gas in judgement system.The method, which can also be checked, judges whether deposited in other types of steam boiler
In incoagulable gas.If the saturation pressure of the corresponding vapor of the numerical value of temperature sensor 12 is less than the number of pressure sensor 13
Value, illustrates there is incoagulable gas in steam generator system, the two difference is bigger, incoagulable gas accounting is heavier.Incoagulable gas meeting
The normal work of boiler is influenceed, heat transfer effect is influenceed, increases the operating pressure of boiler.Accurate measurements are diagnosed, and exclude do not coagulate in time
Property gas is particularly significant.
