YUHONG GROUP - Classification, Working Principle and Application of Steam Boiler

1. Classification of steam boiler:
Steam boiler according to the fuel can be divided into electric steam boiler, oil steam boiler, gas steam boiler, etc.; according to the structure can be divided into vertical steam boiler, horizontal steam boiler, small steam boiler is mostly single, double return vertical structure, large steam boiler is mostly three return horizontal structure.

2. Vertical double return structure and horizontal three-way structure boiler advantageous features:
(1) Vertical double return structure
Vertical oil-fired gas steam boiler using a combustor under the way, two-way structure, fuel combustion is full, stable operation of the boiler; flue pipe inserted in the spoiler, slowing down the smoke exhaust velocity, increase the heat exchange, boiler thermal efficiency, reduce the user's cost of use.
(2) Horizontal three-way structure
Horizontal steam boiler for the shell-type full wet back downstream three-way smoke and fire tube structure, the flame in the large combustion chamber micro-positive pressure combustion, fully extended, low combustion heat load, combustion thermal efficiency is high, effectively reducing the exhaust temperature, energy saving, use of economic. Corrugated furnace chamber and threaded flue pipe structure, not only to improve the heat absorption strength of the boiler, but also to meet the need for heat expansion of the heat exchange surface, scientific and reasonable, durable.

3. Working principle of steam boiler:
Heating equipment (burner) to release heat, first through radiation heat transfer is absorbed by the water-cooled wall, the water-cooled wall of the water boiling vapor, resulting in a large amount of steam into the steam bag for steam separation (except DC furnace), separated from the saturated steam into the superheater, through radiation, convection to continue to absorb the top of the furnace chamber and the level of flue, the tail flue flue flue heat, and make the superheated steam to reach the required operating temperature. The boiler for power generation is usually equipped with a reheater, which is used to heat the steam after the high-pressure cylinder has done its work, and the reheated steam from the reheater goes to the medium- and low-pressure cylinders to continue to do its work for power generation.

4. Application areas of steam boilers:
1.food processing, medical industry and filling of bottles and cans used as a disinfection;
2.Food industry can be used as steaming meat and rice;
3, 3.heating, bathing, production and other purposes;
4.the petrochemical industry, steam can be heated oil, increase mobility, to carry out the petrochemical production process also use steam;
5.production companies, the use of steam on a wider range of uses, such as insulation with foam board, production with steam to heat the raw 7.the construction of aerated bricks should also use steam for drying, but also to generate electricity and so on.
