WNS series gas-fired (oil-fired) steam boiler Steam Product thermal capacity: 1-20 t/h Working pressure: 0.7-2 Mpa Available fuel: Nature gas, coke oven gas, biogas, methanol, liquid propane gas, diesel, heavy oil, light oil, crude oil, etc. Available industries: Heat supplying, chemical, food, textile, printing and dyeing, cigarettes and tobacco, fodder, pharmacy, building materials, brewery, rubber, hospital etc. Introduction 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. Technical advantages: Digitized manufacture • The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime. • The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful. Easy operation and maintenance • Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.
