Two Pass Wet Back Gas Fired Boiler

June 30, 2022

The two pass gas fired boiler structure greatly improves the combustion efficiency and thermal efficiency of the gas boiler. The fuel is burned in the furnace bile under slight positive pressure, and the high-temperature flue gas is turned 180° into the first flue bundle along the furnace bile backward through the re-combustion chamber, and then turned 180° into the second bundle through the pressurized front flue box, which is discharged into the atmosphere after convection heat exchange.

The advantage of wet back gas fired boiler is that the combustion chamber behind the furnace is soaked in water wet-back combustion chamber, there is no trouble of burning, it is because the wet-back combustion chamber is soaked in the water surroundings, but also to improve the radiation heat transfer area and heat transfer efficiency of the boiler, this structure is very popular in the international.

ZOZEN’s WNS2-1.0-Y.Q model 2 ton capacity gas boiler is a highly automated horizontal fire tube boiler, equipped with complete automatic control devices and safety protection devices, to achieve automatic water level control and critical low water level alarm and furnace stop; automatic steam pressure control and overpressure alarm; automatic ignition of the boiler, automatic adjustment of burner fire and flame out protection to ensure the safety of the boiler The boiler automatic ignition, burner fire automatic regulation and flame out protection, to ensure the safety of boiler operation.

Two pass gas boiler, flame in the large combustion chamber micro positive pressure combustion, fully extended, low combustion heat load, high combustion thermal efficiency, effectively reduce the exhaust temperature, energy saving and consumption reduction, the use of economic. The structure of corrugated furnace liner and threaded flue pipe improves the heat absorption strength of the boiler and meets the need of heat expansion of the heat exchange surface, which is scientific and reasonable and durable.
