industrial wood pellets/ briquettes 3 pass 3ton steam boilers machines

SZL(D) type steam boilers are the horizontal dual cylinder portrait arranged, chain grating, pipe steam boiler designed by our technical personnel according to advanced technology and experience from both home and abroad. The technological, performance and environmental protective index of this series of products reach an international advanced level.
The boiler is a quick fitting pipe structure, exit shop after completely assembled; The former part of the boiler body is arranged as a water-cooling wall, the upper part of it is connected to the boiler cylinder, and the lower part is connected to a collection chest, in order to form a combustion room and to absorb the radiated heat from the furnace; 
Its rear part is arranged with a dense convection pipe bundle between the upper and lower boiler cylinders; 
The high temperature smog after combustion shall stand twice before being flushing transversely to the heat accepting surfaces, and shall introduced to the coal saver and singly arranged, and allowed to flow into duster and exhausted from the chimney in the end.
