Biomass fired steam boiler can be fueled by biomass pellets, wood chips, palm shells, straw, etc. ZOZEN’s biomass steam boilers include four series: SZL series double-barrel chain grate boilers, DZL series single-barrel chain grate boilers, DHL series biomass angle tube boilers and SHL series bulk chain grate boilers.
ZOZEN can produce biomass fired steam boiler capacity ranging from 2 tons to 75 tons. Usually, the tonnage commonly used in industrial production process are 2 tons DZL biomass steam boiler, 4 tons DZL chain biomass boiler, 8 tons DZL packaged biomass boiler, 10 tons SZL biomass forming fuel boiler, 12 tons SZL biomass briquette fuel boiler, 20 tons SZL biomass boiler, etc.
According to the characteristics of different fuels, the engineers of ZOZEN boilers have optimized the design of feeding hopper, grate width and length, grate reducer speed, ratio of primary and secondary air, position and direction of secondary air vent, etc., which not only ensure the thermal efficiency of the boiler can reach over 88%, but also effectively reduce NOx emission and fully comply with national standards.
What is the hourly fuel consumption of 1 ton biomass boiler? Hourly fuel consumption = 600,000 calories * tonnage / biomass pellet combustion calorific value / boiler combustion efficiency. Take 1 ton biomass boiler as an example, 1 ton is equal to 600,000kcal, biomass pellet burning calorific value is 3800kcal, boiler burning efficiency is calculated by 80%, so the hourly fuel consumption of 1 ton biomass boiler = 600,000kcal/3800kcal/kg/80%=197kg/h. So it can be concluded that 1 ton biomass boiler consumes fuel in 1 hour is 197kg.
The larger the capacity of industrial boiler, the more biomass fuel is consumed. The higher the calorific value of the fuel, the less the fuel consumption of the boiler for 1 hour. The burning time of tree branches and wood chips is definitely longer than the burning time of straw and leaves. As we all know, the thermal efficiency of industrial boilers has a great influence on the consumption of biomass fuel, the boiler thermal efficiency is high, and the consumption will be relatively reduced. Therefore, purchasing a boiler with high efficiency and full combustion can effectively save operation cost.
DZL series steam boilers are widely used as steam equipment for major production enterprises, providing a large amount of steam for drying, solidification, sterilization and disinfection. Customers from food factory, textile factory, paper factory, pharmaceutical factory, lumber factory, feed factory, slaughterhouse, flower and vegetable shed, brewery, rubber factory, chemical factory and other industries have given good comments on the biomass boilers produced by ZOZEN.
