Biomass fired steam boiler is a new type of high efficiency low carbon environmental protection boiler fueled by biomass pellet. The biomass pellet fuel of industrial biomass steam boiler is all waste crops such as straw, rice straw, fuelwood, sawdust, peanut shell, melon seed shell, corn cob, beet pulp and bark. After pulverizing, mixing, extruding and drying, granular fuel is finally prepared.
The raw materials of biomass fuel are widely distributed and the processing technology is advanced. Biomass pellet is known as green coal, is a clean energy. As the fuel of boiler, its burning time is long, the temperature of reinforced combustion chamber is high, and it is economical, without any pollution to the environment at the same time. As a kind of renewable energy, the burned ash slag is a very good fertilizer that can be recycled and can replace the traditional boiler to burn wood, coal, natural gas and other non-renewable resources. It is a highly efficient and energy-saving environmental protection product.
Industrial biomass steam boiler adopts single boiler tube vertical arrangement, compact structure, small floor area, good flame filling. The furnace adopts the form of curved water-wall tube, pot barrel and left and right header, which can expand upward freely. The water cooling wall is made of light tube, which is easy to manufacture and process. The inner convection tube of the boiler barrel adopts the spiral smoke tube to improve the winding of working medium and increase heat transfer. The outer packing plate adopts pressing plate with beautiful appearance. High thermal resistance material is adopted as the insulation layer with good thermal insulation performance.
This series of industrial biomass boiler adopts unique double-layer secondary air design, improves the ignition condition of biomass fuel, adopts independent air chamber, achieves reasonable air distribution, forms a favorable aerodynamic field in the furnace chamber, makes the combustion temperature high and combustion efficiency high. The whole fast installation form leaves the factory, the electrical control realizes the stepless speed regulation, limit parameter alarm and interlock protection.
Biomass fired boiler overall design is reasonable, full output, the furnace wall, export smoke window part has a certain dustfall effect. The original dust emission concentration of the boiler is controlled below the standard to ensure that the soot emission of the boiler reaches the specified index standard. It can also realize simulated controlled combustion without deflagration. By adjusting the secondary air volume of controlled combustion, the ignition speed of combustion can be controlled. This series of industrial boilers arrange secondary air in front and rear arch to ensure the secondary combustion of fly ash after particle decomposition with high combustion efficiency.
Industrial biomass steam boiler using chain grate, mechanical feed. The whole boiler is reasonable in manufacture, even in feed, stable in combustion and convenient in control. It is not easy to temper and easy to remove ash mechanically. Zozen Boilers products specializing in the production of high quality boiler, qualification certification is complete, complete detection means, rich production experience, welcome everyone to come to advisory procurement. We can also according to the needs of users, one – to – one boiler customized services, by the unanimous approval of many users.
