ZOZEN SZL series biomass-fired steam boiler is package or shop-assembled water tube boiler with double steam drum and chain grate stoker structure. According to different capacity, different numbers of independent air bins are arranged from front to back of the grate. The user can reasonably adjust the air distribution according to different combustion conditions to ensure that the fuel is fully burnt.
On Christmas Eve 2019, General Manager Mr. Zhang Guoping signed an agreement with Shir Baz Kaminzada, CEO of Baheer group from Afghanistan on the papermaking steam boiler project and established a friendly and cooperative relationship. ZOZEN took another firm step towards the internationalization strategic goal! The heating and dissolving, machine shaping, black slurry concentration and squeeze drying of the chemicals in the pulping process all require heat sources, so the boiler is the main driving force for the production of the paper mill.
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%.
