Water tube boilers are designed for larger, high-pressure, and superheated steam applications. SZL series coal fired chain grate boiler is a good example. Membrane water cooling wall structure in combustion chamber, good sealing to prevent heat loss. It is widely used in textile factory, paper factory, food industry, generating steam in industry process.
This product is horizontal double drum longitudinal water tube boiler, furnace side with closely packed waterwall tubes, the back furnished with two sets of convection tubes. The whole boiler divided into the up and down two large factory, and after the boiler in position , masonry the fire grate and the lower furnace wall. Balance of ventilation combustion between the chain grate and the machine. Small stoker labor intensity. Using a unique thermal and turbulent combustion and gasification technology in the design of the furnace structure, no boiler smoke outlet. Furnace with a centrifuge, gravity separation, coupled with the separation of flue dust, a smaller smoke and dust emissions

1 Dividing into up and down two-body assembly, small investment, fast installation. Single layer arrangement, less space.
2 Full water structure, fast heat transfer, high thermal efficiency.
3 Chain grate,zoned-air distribution, covered with a large furnace arch , fast burning speed, wide fuel adaptability.
4 Furnace arch design adopts momentum method, the furnace flue gas form a strong turbulent mixing at high temperatures, to combustion abundantly, the combustion efficiency up to 95%. Soot emissions significantly lower than the national standard, and meet the Class I district environmental requirements
5 Fire grate infinitely variable speeds, flexible adjustment on combustion.
6 Elegant and nice appearance.
7 Pairs of drum full pipe structure, maturity structure: the inspection and maintenance easy and short repair time.
8 Mechanization, high degree of automation.
9 Change based on fuel characteristics and modify furnace arch structure, to achieve the best status.
