LSG The vertical coal-fired steam boiler is composed of main pressure parts such as the head, the drum, the furnace top, the furnace, and the horizontal water pipe. The boiler grate is placed on the upper part of the U-shaped lower leg in the furnace liner, and the flame directly washes the furnace liner and the horizontal water pipe installed in the furnace liner; increasing the radiation heating area. The vertical horizontal water tube steam boiler has good water circulation, and the parts that are washed by the flue gas are cooled by water, and the whole structure is flexible.
The combustion part adopts a double-layer grate combustor, which heats up quickly and boosts pressure quickly. After secondary combustion of unburned gas, it can fully burn, eliminate smoke and remove dust. The elbow pipe arranged on the upper part of the furnace body is the convective heating zone, and the grate tube and the furnace bladder arranged on the lower part of the furnace body are the radiation heating zone. The structure of the furnace body and flue gas flow are reasonable in layout and good heat transfer. The boiler has a reasonable design and simple structure , Easy to operate and maintain, small area, low capital investment, it is one of the ideal equipment for small enterprises and institutions to produce steam and heat.
Performance characteristics of steam boiler:
1. Compared with boilers of the same type, this furnace has a large heating area, rapid heating and pressure rise, high thermal efficiency, and can save 25-30% of coal.
2. One furnace is multi-purpose and convenient for users. The steam produced by this furnace can be used for canteen steaming, tableware disinfection, bath heating, production steam, and local room heating and heating.
3. The furnace adopts natural ventilation, no blower and induced draft fan are needed, and there is no noise.
4. Compact structure, convenient installation, operation and maintenance, can be transported as a whole, suitable for mobile units.
5. Use steam to heat baths, food, heating, steaming rice, etc. The pressure gauge scale is strictly controlled within the design pressure, and the working pressure must not be operated at overpressure at any time.
Application scope of steam boiler:
It can be used for steam needed in the processing of textiles, printing and dyeing, papermaking, food, rubber, plastics, chemicals, medicine, steel, metallurgy and other industrial products, and can be used for heating in enterprises, institutions, hotels, schools, catering, service and other industries , Bathing, air conditioning and domestic hot water.
