Three Operating Processes of a Steam Boiler

A steam boiler refers to the boiler for steam heating or industrial use. To put it simply, the working principle of the steam boiler is that water is heated to become steam within the boiler barrel and fire becomes heat within the furnace. Specifically, the working processes of a steam boiler include three continuous processes: burning and heat release procedure of fuel, heat's transfer to boiler water and the thermodynamic process where water is heated or vaporized.( China Mobile Steam Plant)

Fuel's Burning and Heat Release Procedure

Fuel's burning and heat release procedure refers to the process exactly where fuel reacts chemically using the oxygen from the air under certain temperature within the furnace to release heat. To keep the fuel burning unstably and constantly, boiler man ought to provide the furnace with enough fuel and air non-stop and drain gas and ash as well in order to produce high-temperature gas.

Heat Transfer to Boiler Water Procedure

The heat from fuel burning transfers to boiler water through the water wall heating surface installed in the furnace and also the convection heating surface installed within the gas flue.

Heat transfer procedure proceeds within the furnace within the form of radiation. The heat release from gas to the heating surface proceeds within the type of convection within the gas flue because the gas temperature inclines steadily. And in the metal inside of heating surface, heat primarily transfers from gas side(higher temperature) to water side(low temperature) within the type of conduction and heat is absorbed by the boiler water's continuous flow and circle to enhance the enthalpy in the internal operating medium of heating surface.

Thermodynamic Process Where Water Is Heated or Vaporized

For Oil Fired Boiler or gas fired hot water boiler, the process refers to that boiler water absorbs heat constantly from heating surface to make water temperature reach regulated temperature scale and then it's output in the boiler outlet. For Gas Fired Steam Boiler, the process refers to that boiler water absorbs heat constantly from heating surface and changes into saturated water and then .steam-water-mixture. Following that, vapour-water is separated in the boiler and clean steam is output from the boiler outlet to create the steam whose parameter is regulated.

Working Principle of Electric Steam Boiler or Electric Hot Water Boiler(Electric Boiler Manufacturer)

The working principle of Electric Steam Boiler or Electric Hot Water Boiler is similar to that of Gas Fired Steam Boiler or oil fired steam boiler. The main difference lies in that Electric Steam Boiler or Electric Hot Water Boiler utilizes present to heat water and create steam or hot water. You will find two ways for them to create heat. First, they are able to use the present in the resistance coil to create required heat. Second, they are able to use the current in between electrode and boiler water to create required heat. Each from the ways can gain enough heat to create steam or hot water.
