ZOZEN ZZ series water tube steam boiler adopts the "D" type structure. The furnace is on the right side and the convection tube bundle is on the left. Around the furnace is the membrane water wall. The boiler is equipped with an advanced burner, an economizer and a condenser, which can improve the thermal efficiency to more than 98% and reduce the NOx emission to less than 30mg/Nm³. With an automatic control system, the boiler can achieve unattended operation.
SZS series boiler is double drums, longitudinal arranged, "D" type chamber structure. Furnace is on right side and convection tube bundle is on the left, super heater is arranged at convection tube bundle. The body is fixed on the basement by middle and both end flexible supports and make the boiler to expand horizontally to sideways. Around furnace is membrane wall. Furnace and tube bundle is totally separated by the membrane wall at the left side of the furnace. The back part of bundle is sparse shift structure, front part is aligned structure. Smoke from furnace outlet enters re-burning chamber, bundle area, and then from left front part enters spiral fin coil economizer and condenser, finally discharged to atmosphere through chimney.
