Paper Mill Circulating Fluidized Bed Boiler Project

Circulating fluidized bed boilers are the best choice for industrial production, and the combustion technology of these boilers is an emerging clean coal-fired technology. The paper industry has huge energy consumption and serious environmental pollution. The circulating fluidized bed steam boiler produced by ZOZEN with energy saving as the core is especially suitable for paper industry production.

circulating fluidized bed boiler

The circulating fluidized bed boiler is able to burn a variety of fuels, bituminous coal, anthracite, lignite and biomass fuels, and through multiple cycles is the fuel particles stay longer inside the boiler, the combustion is more adequate and the efficiency of combustion is higher. The circulating fluidized bed boiler can obtain the desulfurization rate as high as 80%-90% under the appropriate calcium-sulfur ratio and limestone particle size, and at the same time, because the combustion temperature of circulating fluidized bed boiler is not very high, it can adopt the way of multi-stage air supply, which makes the pollutants produced by circulating fluidized bed boiler during combustion far lower than the ordinary furnace type boiler.

ZOZEN boiler has customized SHX series circulating fluidized bed steam boiler for paper production line. This series boiler belongs to low temperature combustion, which can realize direct desulfurization in the combustion process, and the technical equipment is economical and simple, with high desulfurization efficiency; meanwhile, the high temperature cyclone separator is not only efficient and wear-resistant, but also has a separation efficiency of ≥98%, which, together with the design of large furnace chamber and low flow rate, prolongs the residence time of coal particles in the furnace chamber, ensures the full combustion of coal, and effectively improves the combustion efficiency of the boiler; the convection heating surface is also designed with multiple The convection heating surface is also designed with multiple folding smoke plates, which increases the flue gas flow and plays the role of dust reduction. In addition, the serpentine tube coal saver and air preheater further improve the overall thermal efficiency of the boiler, which can reach more than 89%.
