Description of DZL Chain Grate Coal Fired Steam Boiler


DZL Chain Grate Coal Fired Steam Boiler is single drum three-return water tube and fire tube steam boiler. It adopt chain grate coal feeding design. Save a lot of labour work for worker. During the boiler working, worker just need to add coal every two hours. Both sides of the wall around the furnace are radiation heating surface. Two wings of furnace are convective heating surface. The lateral of boiler body is shell of the three-dimensional shape.The boiler uses the vaulted tube plate, spiral gas tube to make the thermal efficiency higher and output capacity sufficient.
