Abstract

Se revela un método para la combustion de licores que contienen cloro en una caldera de recuperacion de químicos en una fábrica de pasta de celulosa, donde la caldera de recuperacion comprende rociadores de licor agotado para alimentar el licoragotado y varios niveles de aire de combustion, tal que la temperatura de combustion en la caldera de recuperacion se aumenta en una zona, donde se quema un licor o efluente que contiene cloro, para mejorar la volatilizacion del cloro provenientedel licor o el efluente hacia los gases de escape para producir sales que contienen cloruro, y donde los gases de escape se tratan para eliminar las sales que contienen cloruro.A method for combustion of chlorine-containing liquors in a chemical recovery boiler in a cellulose pulp mill is revealed, where the recovery boiler comprises spent liquor sprayers to feed the lycopene and various combustion air levels, such that the combustion temperature in the recovery boiler is increased in an area, where a liquor or effluent containing chlorine is burned, to improve the volatilization of chlorine from the liquor or effluent to the exhaust gases to produce salts containing chloride, and where the exhaust gases are treated to remove salts containing chloride.
