The boiler body of WNS series boilers adopts wet-back structure. The combustion, water level, temperature and steam pressure of the boiler are automatically adjusted and protected, which can realize fully automatical operation to ensure safety and reliability. The large-diameter corrugated furnace of this boiler ensures sufficient combustion of natural gas. Combined with an advanced low NOx burner, it can easily achieve the requirement of NOx≤30mg/Nm3. In addition, the boiler is also equipped with energy-saving equipment at the end of the boiler flue, so that the boiler thermal efficiency can reach over 98%.
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.
