Thereby completing the whole heating cycle from cold water entry to steam output.
3. Safety control:
3.1 Water supply control
The water level of the evaporator body is automatically controlled through water level meters and water level sensors arranged on two sides of the evaporator body; when the water level of the evaporator body drops, under the electrical interlocking action of the water level sensors at the two sides and the electric feed pump, the electric feed pump automatically starts to supplement water for the evaporator body system; ensure the normal water level of the evaporator body.
3.2 pressure control
3.2.1, monitoring the operating pressure of the evaporator through a pressure gauge.
3.2.2, when the evaporator normally runs, the pressure controller and the pressure relief safety valve are in a static state; when the operating pressure of the evaporator rises and exceeds the set pressure, the pressure controller instantly cuts off the power supplies of the external blower and the external induced draft fan through the electric interlocking device, so that the external blower and the external induced draft fan stop supplying air and inducing air, and the rapid combustion of fuel in the hearth is stopped; the temperature of the hearth is reduced. Meanwhile, the pressure relief safety valve can be opened instantly for pressure relief; ensuring the safety. After the pressure is reduced to a normal value (no abnormal factor), each functional configuration can run normally.
