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.
Steam boilers play a key role in the production process of dye intermediates, proving steam for synthesis, drying and other processes. SZS gas-fired water tube boiler adopts the structure of membrane water wall for better sealing effect and higher thermal efficiency; In addition, to effectively reduce the NOx emission, the boiler is equipped with a large volume furnace and an advanced NOx burner imported from Europe, so the NOx emission can reduce to 30mg/Nm3.
Wood processing is molding the wood under the action of a mould after being softened, bending the curve shape that the design requires, the following procedure is drying and shaping. In this case, wood cannot be heated and shaped by fire, therefore, heating and softening the wood by steam has been the only choice.
The new generation biomass-fired boiler, which is designed and developed by ZOZEN, has optimized the design of the feeding hopper, the length and width of the fire grate, rotary speed of gearbox, 1st and 2nd air ratio, vapor orientation and position, etc; these methods not only take the lead in solving the above problems, but also ensure the full combustion and the thermal efficiency can reach up to 88%; in addition, ZOZEN biomass-fired boiler adopts appropriate heat resisting grate bars, which effectively improve the reliability of the boiler and ensure the stable running of the boiler for a long time.
