Great assembly level SZL Coal Fired Steam Hot Water Boiler wiht small heat loss


HD SZL packaged water-tube steam boiler is the double-cylinder, water-tube assembly, chain grate boiler. Two cylinders are laid at the upper and lower level of boiler longitudinally along the center. Front section of the upper cylinder and water-cooled tubes at side walls form the radiation-heating area in the hearth. While the rear section and tube bank in the lower cylinder serve as convection-heating area. Coal econnomizer is mounted at the rear of bolier. Some heat of hot combustion fume is absorbed by the hearth. Then hot combustion heat flows to the convection heating area through cooling chamber and exhausts outside with the chimney via coal economizer, dust collector and draught fan.
