ZOZEN biomass-fired steam boilers
are well preferred in the international market

We cooperate with Shanghai Jiao Tong University to research, develop and manufacture biomass boilers that use wood chips, straws, palm shells, mesocarp fiber, empty fruit bunch (EFB) fiber, rice husk and other wastes as fuels in order to achieve zero carbon dioxide emissions. After numerous tests and simulations, we have developed a reasonable structure of furnace arch, furnace wall and furnace heating surface that guarantees combustion efficiency and evaporation rate. NOx emissions of our biomass boilers can be as low as 100 mg/Nm3 with thermal efficiencies up to 90%.
