ZOZEN produces DZL, SZL series package chain grate coal fired boilers with high thermal efficiency, high overload capacity and wide adaptability to coal types. SZL series chain grate coal-fired boiler will be large chain grate boiler combustion system water-cooled arch technology and membrane water-cooled wall technology cleverly applied to the assembly boiler. Chain grate boiler machine is widely used in many fields and industries such as pharmaceutical, chemical, food, gold machinery, mining, etc.

The chain grate boiler combustion system operates stably and the coal type is adaptable, plus it has its own inertial dust removal function, so that the exhaust smoke blackness and the original dust concentration of the boiler meet the environmental protection requirements. The 25 ton coal fired boiler is generally applied to larger projects, such as heating, power generation, large enterprise production, etc. The coal-fired boiler is a more traditional boiler model, but compared to other boiler models, the coal-fired boiler is low cost, stable fuel and easy to use.

The structure of industrial coal-fired boiler consists of upper pot, lower pot, water-cooled wall, convection tube bundle, coal saver, air preheater and other components. The front part of the boiler consists of a water-cooled wall forming the furnace chamber, and the front and rear water-cooled walls forming the front and rear water-cooled arches, convection tube bundles are set between the upper and lower boiler barrels, and the tube bundles are equipped with transverse partitions so that the flue gas flows horizontally, and the rear part of the boiler is arranged with coal saver and air preheater. The combustion equipment adopts scale-type chain grate, and the ventilation structure is divided into compartments, with sensitive adjustment.

ZOZEN production of coal  biomass dual use boiler automation is very high, greatly reducing the work intensity of the operator, automatic water supply, automatic control, intelligent automation. Thermal efficiency is also one of the issues that users are very concerned about. The higher the combustion rate, the more it directly affects the thermal efficiency of the boiler equipment, and only when the combustion rate is achieved can the thermal efficiency be guaranteed. New type coal/biomass fired dual use boiler, automatic feeding, reasonable control of the feeding amount. New coal biomass fired boiler, the fuel is gasified and burned in the furnace chamber, which greatly improves the combustion rate.
