Used in Boiler The height of a chimney affects its ability to deliver flue gas to the external environment through the chimney effect. In addition, the diffusion of pollutants using chimneys at high altitudes can reduce the impact on the surrounding environment. A chimney high enough to allow the chemicals in the air to partially or completely neutralize themselves before reaching the ground level, in the case of chemical erosion. Dispersion of pollutants over a larger area reduces their conc...

Introduction: As a new type of mature high-performance with low-pollution clean coal technology. circulating fluidized bed combustion(CFBC)technology is unlike others that it has a lot of unique characteristics. 1. Circulating fluidized bed is of low-temperature combustion, therefore nitrogen oxides emissions of such boiler is much lower than that of coal-powder boiler, and such boiler could directly desulfurize during combustion process. Circulating fluidized bed boiler with high desulfuriza...
