SZL Double Drum Water Tube Coal Fired Hot Water Boiler

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
