biogashorizontal

Biogas Steam Boiler Hunan Along New Energy Technologies Co., Ltd is committed to supplying reliable steam boiler. Our WNS series biogas-fueled steam boiler is horizontal positioned wet back type,with three-back fire tubes and wave-shaped bottom-located furnace gallbladder.Operable fire doors for front and rear air boxes with saddle type base.The shell of boiler is made of soft milky white color plates. Symmetrical layout of heat transferring tube is the combination of threaded pipe and light tubes. The large heat transferring area enables thermal efficiency of boiler to be higher than 90%. Very harsh application of butt welding is implemented to avoid safety hazards,increase safety factor and life-time for boiler. Water fed into boiler at upper position,the high-speed turbulence of water makes convection,radiation and conduction maintain in ideal state and continuously destroy the bubbles and attachments on the laminar boundary,to ensure good water-cooling on the heating surface of boiler.The design of low-positioned combustion chamber makes the safe range of water level bigger,as well as bigger the vapor-phase room.The unique steam-water separator ensures better steam quality(Dryness level higher than 97%). Electrode type water level control system, with high, medium,low, very low water level protections. Multiple security interlock protection devices for projections of steam pressure, high temperature, burner flameout, safety valve, password, explosion-proof gate etc, so that the safe operation of the boiler is always in a controlled state.
