Small steam boiler and coal steam boiler and heating boiler equipped with baltur burner for hotel
Small Steam Boiler Structural features
1. The small steam boiler type is a horizontal quick-install boiler, and the water circulation mode is natural circulation. The small steam boiler heat exchange system consists of a drum, a left and right header, and a water-cooled wall. The main heating surface is designed to install the furnace water wall. In addition, the main heating section of the boiler is made of seamless steel pipe for 20# low and medium pressure boiler, and the drum is made of special steel plate for boiler. The left and right headers are made of seamless steel tubes.
2. The grate has a reasonable air distribution, the combustion chamber is large, and the coal type has strong applicability. Adapt to all types of bituminous or anthracite, mixed coal. The fuel is fully burned. Since the high-temperature flue gas will enter the settling chamber and then enter the flue from both sides, the exhaust and dust removal effect of the equipment is very good.
3. The water circulation is simple, the structure of the pressure-bearing parts is reasonable, and it can be safely operated under the condition of ensuring water quality. At the same time, high-standard, high-quality auxiliary machines, accessories and automatic control equipment are used to ensure safe and stable operation of the biomass steam boiler.
4. The small steam boiler body has a square coiled tube on the heating surface, and coal steam boiler structure is a serpentine convection heat exchange tube. This structure is suitable for single furnaces and double furnaces.
5. According to the waste heat usage of the equipment, air preheater, steam waste heat equipment and hot water economizer are arranged at the tail of the boiler for waste heat recovery. This structure can effectively reduce the exhaust gas temperature, improve the coal steam boiler heat efficiency and reduce fuel consumption.
6. The coal steam boiler is heated surface processing using a fully automatic gas shielded welding process, and X-ray inspection of all solder joints. Ensure that the welding quality is stable and reliable.
7. Combine industrial automation control technology, Internet technology, computer software and artificial intelligence technology to establish biomass fired steam boiler Io T platform, which can realize remote human-computer interaction and data sharing, and realize automatic control.
