Steam Generator Working Principle


A steam generator is a device that converts fuel or electrical energy into steam. Its core principle is to boil water and generate steam through energy transfer. It is widely used in industrial production, heating, power generation, and other fields, and is a key energy conversion device.

During operation, the steam generator first requires a continuous supply of qualified water. This water is typically pre-treated, such as softening and deoxygenating, to prevent impurities from forming scale during the heating process, which can affect equipment efficiency and lifespan. The treated water then enters the evaporator's inner tank or piping system, forming a closed water circulation loop.

 

Next, energy transfer and water heating occur. Heating methods vary depending on the energy source: Oil- or gas-fired steam generators use a burner to mix fuel and air, igniting it to produce high-temperature flue gas, which then passes through the furnace for heat exchange. Electric heating uses heating tubes to directly heat the water. Biomass or coal-fired steam generators release heat through fuel combustion. During this process, the water absorbs heat, gradually increasing in temperature until it reaches boiling point.When water is heated to its boiling point, it vaporizes, transforming from liquid to gaseous steam. The steam then enters a steam-water separator to further increase the steam's dryness. Steam accumulates within the enclosed space, gradually increasing the pressure within the system. To ensure safe and stable operation, the steam generator is equipped with a pressure control system. When the pressure reaches the set value, a regulating valve controls steam output and replenishes water to maintain continuous operation.The steam generator is also equipped with multiple safety protection devices, such as a pressure safety valve, a water level controller, and over-temperature protection, to ensure timely shutdown in abnormal situations and avoid accidents. Through this cyclic process, the steam generator can continuously and stably produce steam at a certain pressure and temperature to meet the energy needs of different scenarios.
