The wide distribution of biomass resources and their suitability for on-site development and utilization make the development of biomass energy combustion technology suitable for industrial boilers in various regions beneficial for saving conventional energy and optimizing China's energy structure.

The Zhengguo DZL fast loading boiler is a single drum longitudinal chain grate boiler suitable for burning formed biomass fuel, as well as pure coal or mixed coal with formed biomass fuel. There is an economizer at the rear. The discharged ash and slag can be directly used as farm manure, which is an efficient, energy-saving and environmentally friendly product. Equipped with a drum induced draft fan for mechanical ventilation and a spiral slag extractor for mechanical slag removal, with complete control and monitoring instruments, the boiler operates safely and reliably.

Zhengguo SZL type assembled water tube boiler adopts a double drum vertical arrangement, and the combustion method is a chain grate suitable for burning biomass solid fuel. The water-cooled walls on both sides of the furnace adopt a membrane water-cooled wall structure; The water-cooled wall tubes on the front and rear walls of the furnace extend downwards to the upper part of the grate, forming front and rear arches. Behind the furnace is the combustion chamber and convection tube bundle, with an economizer at the tail. The flue gas enters the tail flue through the furnace, combustion chamber, convection tube bundle, and economizer, and is discharged into the atmosphere through the dust collector, induced draft fan, and chimney. There is secondary air arranged on the front wall, controlled by valves, which is put into use when burning biomass fuel to enhance combustion, fully burn the fuel, and improve combustion efficiency. Adopting a higher feed inlet to meet the demand for biomass fuel.

Application areas: food factories, textile factories, paper mills, pharmaceutical factories, wood factories, feed factories, slaughterhouses, flower and vegetable greenhouses, breweries, rubber factories, chemical factories, etc
