Selection and Design of Flue Dust Removal Equipment for 800t/h Coal Fired Boiler

Abstract                 

In recent years, with the development of industry, coal-fired boiler has increased greatly, the smoke from these boilers is one of the causes of haze weather, haze weather has seriously affected our life, transport and human health, so removal of coal-fired boiler dust is particularly important. This design mainly completes the selection and design of flue dust removal equipment for 800t/h coal fired boiler. The type of boiler and coal are selected according to the given boiler rated evaporation. Coal consumption, flue gas volume, flue gas concentration and the dust removal efficiency are calculated according to the boiler's parameters and the content of each elemet. The appropriate dust precipitator is selected based on a series of requirements and sizes of dust collector are calculated, the main view, left view and flange of dust removal equipment are painted by AutoCAD .

Key Words:coal- fired boiler  electric dust collector  selection design
