Biogas steam boiler

This series biogas steam boiler is three return fire tube steam boiler.It equipped with good performance burner and advanced techniques.The burning control,water feed,programs run,etc,is full automatic.This fantasy boiler is safe and reliable,and also has the advantage of compact structure,simple operation,easy installation,high efficiency,less pollution and noise,etc.
 

Biogas steam boiler is widely used in Medicine, chemical, light industry, textile, building material, cultivation, food and beverage, plastic foam, printing, dyeing and washing, rubber processing, paper products,wood processing, hotel, clothing and leather manufacturer etc.
 

1. Three-return structure: adopts the international popular shell-type three-return ,full wet back structure, combustion chamber large volume design, to ensure the combustion more fully. Fuel combustion in the furnace by micro-positive pressure, high temperature smoke gas along the boiler furnace go backward through reverse flow combustor turn 180°into the first smoke flue tube bundle, pass the oppressive front smoke box then turn 180°into the second smoke flue tube bundle, after the convection heat transfer injection into the atmosphere.

2. The corrugated furnace: the combustion chamber adopt full corrugated furnace structure, not only strengthen the flue gas disturbance, but also increased the radiation transfer area; not only increase the rigidity of the furnace, but also effectively weaken expansion stress of furnace; both enhance the heat transfer effect, and promote the fuel combustion in the furnace.

3.The unique pipe and tube sheet welding technology: adopts the first pre-expansion and then all welding, and then expanded connection advanced technology. Both to prevent the pipe gap corrosion, and enhance the welding strength; adopts the high heat transfer coefficient of the screw smoke tube, to strength the convective heat transfer effect, reduce the exhaust gas temperature, improve the boiler thermal efficiency.
