Steam boilers

Steam boiler means that the water is heated to a certain temperature steam parameters and production of industrial boilers, water becomes steam drum in heat, fire emits heat in the furnace is a steam boiler works. Steam boilers of special equipment, design, processing, manufacturing, installation and use of the boiler must accept the supervision and technical supervision departments, users only get boilers use permit to use the steam boiler.

Steam boilers in accordance fuels (electricity, oil, gas) can be divided into electric steam boilers, fuel steam boiler, gas steam boiler of three; structure can be divided according to vertical steam boilers, horizontal steam boilers, steam boilers, mostly small and medium sized single, double the return of the vertical structure, large steam boilers for the horizontal structure of the three return. Steam boiler fuel can be divided in accordance with electric steam boiler, oil-fired steam boiler, gas steam boilers, etc.; structure can be divided according to vertical steam boilers, horizontal steam boilers, steam boilers, mostly small single, double the return of the vertical structure, large steam boilers for the return of three horizontal structure.

Heating equipment (burner) heat release, the first to be absorbed by the water wall radiation heat transfer, water wall boiling water vaporization, carried a large amount of steam into the drum separator (except DC furnace), separated into saturated steam superheater, by radiation, convection and continue to absorb the level of the top of the furnace flue, flue gas heat backpass, and make superheated steam to achieve the required operating temperature. Power generation boilers usually also provided with reheat, steam is used to heat through high-pressure cylinder acting after the reheater reheat steam go out, the low-pressure cylinder to continue acting power.
