The SHL series bulk steam boiler is a natural circulation water tube boiler with two cylinders arranged horizontally. The upper and lower drums and water wall tubes are transversely arranged to form a shaft type furnace, and the convective tube bundle header is composed of the boiler body. The rear is equipped with economizer and air preheater. It can set Superheater in furnace chamber. The combustion equipment is scale grate. It has stepless speed control, bulk production, on-site assembly masonry. The flue gas flow is multiple return.
The boiler belongs to low pressure small industrial boiler. It is limited by the application conditions. It needs to stop the furnace and start the furnace and load economic changes. It uses double pot, which is based on this. Because the double drum water capacity is large, and has a greater heat storage capacity, so the ability to adapt to load changes, and stable pressure, good operating characteristics, natural circulation characteristics of good conditions. It is not enough to rely solely on radiant heating surface for low pressure boilers, and more convective heating surface can be arranged for double drums. The utility model adopts a transverse type, which enables the boiler to have compact structure, small size and convenient installation. Steam boiler adopts natural circulation. Because the hot water carries only physical sensible heat, there is no latent heat of evaporation. Steam carries much more heat than hot water. Steam boiler water concentration, water quality changes, so the supply water hardness requirements slightly higher. In order to reduce the incomplete combustion loss and improve the thermal efficiency, a burnout chamber is arranged between the furnace and the boiler tube bundle. The burnout chamber can regulate the reasonable smoke speed. Fly ash in the flue gas plays a role of fly ash precipitation, but also undertakes part of the heat transfer, so that the unburned materials are fully burned. At the same time, it also protects the rear tube from abrasion.
The boiler has the following characteristics:
1. The boiler has the advantages of fast temperature rise, high thermal efficiency and small land occupation.
2. The grate adopts the scale type grate, and the operation reliability is greatly improved.
3. The furnace arch wall can be poured. It has good sealing performance, improved ignition conditions, environmental protection, energy saving and strong combustion.
4. It has a high degree of automation, smooth operation, safe and reliable, and high service life.
