SZL series coal-fired hot water boiler product introduction

SZL series double-drum longitudinal-type chain furnace drain hot water boiler adopts quick assembly or assembly structure. 4~6t/h is the structure of quick-loading water pipe, which is factory-installed after being completely assembled; 6~35t/h is composed of two upper and lower parts, the upper part is the body heating surface, and the lower part is the burning equipment. The front end of the 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 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.
