With the continuous development of air pollution control, biomass pellet boiler, which use biomass energy as fuel, have been recognized and promoted by many local environmental protection departments by virtue of their green and low operating costs, effectively filling the gap of gas boilers. As a leading enterprise in the industrial boiler industry, Zhongzheng Boiler continues to innovate, design and optimize the structure of biomass pellet boiler, and produce energy-saving and environmentally friendly boiler products, which can achieve ultra-clean emissions and become a new choice for major enterprises to save energy and reduce emissions. In this article, Zhongzheng Boiler introduces the principle of several common furnace type biomass pellet boiler for the main furnace type.
Among them, SZL series biomass pellet boiler is a double-boiler longitudinal chain furnace drain tube boiler, the front end of the boiler body is surrounded by a water-cooled wall connected to the upper part of the pot and the lower part is connected to the collector box to form a combustion chamber to absorb the radiant heat of the furnace, and the rear end is arranged with a dense convection tube bundle between the upper and lower pot.
The principle of this biomass pellet boiler is that the air required for the combustion of biomass pellets is sent by the blower to the independent air bins in the lower part of the grate, which enters the furnace chamber through the grate and reacts with the coal above the grate for combustion, and each independent air bin has an air volume adjustment mechanism to achieve precise air distribution for different combustion sections, so as to improve the burning rate. The high temperature flue gas generated by combustion enters the S-type convection section, then enters the coal saver, which reduces the flue gas temperature to the economic exhaust temperature, and finally enters the dust collector, with remarkable energy-saving and environmental protection effects.
DZL type series biomass pellet boiler is a horizontal three-way water fire tube chain grate boiler. The body of the boiler is a single pot longitudinally arranged, the pot is arranged with threaded smoke and fire tube to form a convection heating surface, and the pot and the water-cooled wall on both sides form a radiating heating surface of the furnace. The boiler combustion equipment adopts light chain grate; the whole fast-assembled form leaves the factory.
In the market, the application of biomass pellet boiler has been relatively mature, but because of the wide range of fuel sources, there are often inadequate combustion, ash, coking and other phenomena. In order to effectively solve this problem, Zhongzheng boiler and Shanghai Jiaotong University cooperation, in-depth study of the principle of material pellet boiler, combustion tests on a variety of domestic and foreign biomass, the establishment of mathematical models, and according to the experimental results, scientific arrangement of the furnace arch, furnace wall, furnace heating surface and secondary air, design of biomass boiler structure more reasonable and efficient, can ensure that you provide fuel, I provide a suitable furnace type We can guarantee that you provide the fuel and I provide the right type of boiler.
At present, our biomass pellet boilers cover four series of industrial boilers DZL, SZL, DHL, SHL and ZZ series of power generation boilers, which can be applied to biomass pellets, wood chips, palm shells, straw and other fuels. With excellent performance and quality, the biomass pellet boilers produced by Zhongzheng have settled down all over the world and gained a good market reputation.
