The Design of Flue Gas Dust-removal System for 1000 t/h Coal-fired Boiler
Abstract: The Design of flue gas dust-removal system for1000 t/h coal-fired boiler.
According to a given boiler capacity, calculating coal consumption, quantity of boiler flue gas.According to analysis of flue gas dust concentration and the dust Remover of the advantages and disadvantages of choosing the right filter.According to the principles of layout and inner diameter of the pipe, piping layout and determine the filter diameter.Based on the total evaporation of all boilers and emission standards of air pollutants, design decisions chimney height.According to the flue gas exit velocity and flue gas flow, design chimney dimensions.Calculation of air flow and air pressure according to the design chosen fan type.
Keywords: coal-fired boiler; electric dust catcher ;flue gas dust-removal system;
