The electric heating steam generator is primarily made up of a water supply system, an automatic control system, a furnace & heating system, and a safety protection system. Its fundamental working principle is as follows: A set of automatic control devices ensures that during operation, the liquid controller or high/medium/low electrode probes provide feedback to control the water pump’s on/off status, water supply duration, and the furnace’s heating time. The steam pressure adjusted by the pressure relay is continuously output alongside the continuous steam discharge; as steam is released, the furnace’s water level drops steadily. When the water level reaches the low level (mechanical control) or medium level (electronic control), the water pump automatically starts replenishing water, and stops when the high water level is reached. Meanwhile, the electric heating tubes inside the furnace continue heating to generate steam continuously. The pointer pressure gauge on the control panel or the top of the generator immediately displays the steam pressure value, and the entire process can be automatically indicated by signal lights.
