7 ton Gas Fired Condensing Steam Boiler

This series of steam boiler structure design horizontal three return wet-back structure, boiler smoke pipe in water. Equipped with finned tube condenser and perfect insulation design. The boiler smoke box is sealed and the labyrinth structure is adopted to effectively avoid the occurrence of smoke leakage. The corrugated furnace with good expansion performance is used in natural gas boiler. The furnace size is combined with the flame diffusion, and the flue gas circulation area decreases successively. Make the flue gas flow at the same speed, to ensure the heat exchange time of high temperature flue gas in the furnace, so as to achieve excellent heat transfer effect.
