Abstract:

In view of the characteristics of wet desulphurization flue gas of coke oven,four kinds of technique routes of coke oven flue gas plume removal are compared.The result shows that the flue gas condensation and reheating method is the best technical route,which can not only realize completely effect of wet plume elimination for coke oven flue gas,but also reduce the pollutant emissions for the flue gas.With the project of coke oven flue gas plume removal as research object and base on “Temperature-humidity curve and tangent diagram”,research is carried out for the influence of heat transfer temperature of MGGH heat exchanger and flue condenser on steam consumption and system operating cost.The study shows that the steam consumption and operating cost both decrease with the increase of temperature transfer of MGGH heat exchanger and flue condenser,in addition,the operating costs of the system is proportional to the steam consumption when at the same condition that white plume can be removed.
