Compared with traditional coal-fired steam boilers, biomass steam boilers are more intelligent and efficient. Its thermal efficiency is higher, and its thermal efficiency is above 82%. The furnace space of the rice husk steam boiler is further enlarged, and the heating area of the boiler is further increased. Thereby reducing the loss of fuel consumption and shortening the working time. The safety factor of the product has been further improved. Multiple protective devices such as high temperature, high pressure, water shortage, and automatic power-off have greatly improved the safety factor of the boiler.
This series of boiler products adopt a single drum, vertical type, chain grate structure. Biomass boiler adopts in-furnace smoke reduction and dust reduction technology, feeding technology, in-furnace fly ash separation technology, independent air chamber technology, etc. The boiler has high thermal efficiency and long service life. The eight-shaped wall in the furnace and the exit smoke window have a certain effect of reducing dust. The original dust concentration of the boiler is controlled below the standard, which ensures that the smoke and dust emission of the boiler meets the national environmental protection regulations.
The rice husk steam boiler adopts a unique double-layer secondary air design, which improves the ignition conditions of biomass fuel. The independent air chamber is adopted to achieve a reasonable air distribution. An aerodynamic field conducive to combustion is formed in the furnace, with high combustion temperature and high combustion efficiency. The heating surface and combustion device of this series of steam boilers are reasonably arranged, and the boiler efficiency is 4-5% higher than the national standard. Reasonable smoke speed design, the boiler heating area does not accumulate dust, does not wear, and can maintain high efficiency, full load and safe operation for a long time without soot blowing. The strong radiation arch is used to ensure that the anthracite is on fire in time, and at the same time, it can reasonably organize the flame to burn and improve the degree of fuel burnout.
DZL series steam boilers are equipped with steel threaded smoke tube air preheaters to provide reasonable hot air. Promote the timely ignition and full combustion of fuel. The steam boiler enlarges the area of the grate, increases the burning time of the fuel, and reduces the heat loss of incomplete combustion of the fuel. The boiler adopts a large grate piece, which does not leak coal and has uniform ventilation. It can clean the ventilation holes by itself, and has high strength and stable combustion. All independent circuit design is adopted, and reasonable ejection circulation is adopted. The flow rate of the medium in the heating surface loop is higher than the national standard requirement.
In the rice husk steam boiler, the smoke and dust at the outlet of the furnace are separated by inertia, which effectively reduces the dust concentration in the exhaust smoke. At the same time, it also reduces the wear on the rear heated surface. The DZL series biomass boiler has a compact structure, and the installation volume is smaller than other types of boilers of the same capacity. Shorten the installation cycle and reduce the boiler cost. The steam boiler has a large water volume, which is beneficial to power outage protection and has a strong ability to adapt to load changes. ZOZEN’S boiler has been further optimized design. Many improvements have been made in the boiler chain grate, air distribution and furnace arch. The biomass fired boiler has been further improved in terms of safety, energy saving, environmental protection and other technical performance.
