WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.
The full corrugated furnace has better thermal expansion, effectively absorbs thermal expansion, avoids stress concentration and prolongs service life. An explosion-proof door is located directly opposite the flashback chamber to ensure safe operation of the boiler. The utility model of 2000 kg per hour gas fired boiler adopts a wet back water cooling large back combustion chamber, which has a large radiation heating area, a large combustion space and sufficient combustion. The second return pipe adopts a threaded pipe to enhance heat transfer and improve boiler efficiency.
The accessories of 2 ton gas fired boiler which used for chemical industry including pressure controller, pressure gauge, suspension loop, smoke box, combustion engine, safe valve, outlet valve, water level gauge, water inlet and drain valve.
