SZL Series Hot Water Boiler Advantages

CNC Manufacturing Technology

SZL series double-drum longitudinal-type chain furnace drain hot water boiler adopts quick assembly or assembly structure. 2.8~4.2MW is the structure of quick-loading water pipe, which is factory-installed after being completely assembled in the factory; 4.2~29MW is composed of two upper and lower parts, the upper part is the body heating surface, and the lower part is the combustion equipment.

The front end of this series of coal fired boiler body is surrounded by the upper part of the water-cooled wall and the lower part of the drum is connected with the header to form a combustion chamber to absorb the radiant heat of the furnace, and the rear end of the SZL series hot water boiler is arranged with a dense convection tube bundle between the upper and lower drums, and the high-temperature smoke after combustion. After passing through the second return stroke, the gas is flushed to the convective heating surface and then led to the separately arranged economizer, and finally enters the dust collector and is discharged through the chimney.
