Biomass steam boilers are manufactured using up to the furnace for easy full combustion of biomass fuel. According to the combustion characteristics of biomass fuel, a reasonable furnace arch is designed to improve the burnout degree of fuel and eliminate black smoke. Biomass fired boiler system adopts high strength large grate, suitable for biomass boiler fuel transportation and combustion. For large grate with roller device to improve the safety of grate, convenient combustion adjustment.
The biomass fired boilers manufactured by Zozen Boilers adopt a unique high-position feeding device. It is suitable for biomass briquette forming fuel to prevent pre-combustion and up-combustion. This series of steam boilers uses a unique secondary air supply device to blow the flame back to prevent the flame from entering the hopper, and strengthen the oxygen supply to promote combustion and prevent the formation of black smoke.
This series of boilers, through reasonable arrangement of heating surfaces and combustion devices, make the boiler’s thermal efficiency 4 to 5 percentage points higher than the standard. The biomass fired boiler system has a reasonable smoke velocity design and does not accumulate dust or wear on the heating surface. The heating surface of this series of biomass fired boilers can maintain high efficiency, full compliance and safe operation for a long time under the condition of no ash. The boiler has a large water volume, which is beneficial to power outage protection and has a strong ability to adapt to load changes.
The biomass boiler is designed with all independent loops in total. For the hot water boiler, a reasonable ejection cycle is also adopted. The flow rate of the medium in the heating surface loop is higher than the standard. The inertial separation of the smoke and dust at the outlet of the furnace can effectively reduce the dust concentration in the exhaust smoke and reduce the wear on the rear heating surface. This series of boilers has a compact structure and a smaller installation volume than other boilers of the same capacity, which shortens the installation period and reduces the cost of the boiler room.
This series of steam boilers are equipped with two-wing flue, so that the flue gas can smoothly enter the front smoke box, so that the temperature of the previous tube plate is the same. Avoid tube sheet cracks due to temperature stress. The inside of the drum adopts a single-pass threaded smoke tube to enhance the heat transfer effect. At the same time, the threaded smoke tube has an automatic dust removal function, which avoids the accumulation of dust in the smoke tube. Its front and rear arches adopt a water-cooled wall tube as an integral casting structure supported to form a permanent arch.
The biomass fired boiler system adopts a new crank arm screw adjustment structure, so that the air conditioning and ventilation section ratio reaches 100%. The boiler can be adjusted flexibly and air distribution is even. Design a push-pull gate ash cleaning device, the gate adopts heat-resistant cast iron finishing sealing structure. This can effectively prevent secondary combustion deformation and grate air leakage.
