SZL biomass pellet steam boiler

SZLburnBiomass pellet steam boilerIt is a single drum longitudinal chain grate boiler. Suitable for burning molded biomass fuel, it can also be pure coal or mixed coal with molded 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.
SZLburnBiomass pellet steam boilerAssemble a water tube boiler with a double drum vertical arrangement and a chain grate combustion method. The rated evaporation capacity is 4~20t/h. The boiler burns biomass formed 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. This not only increases the sealing performance of the boiler, but also increases the furnace volume and heating surface, while reinforcing the strength of the rear arch. 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.
