Hot gas enters an exhaust heat boiler 7, where it is cooled, from an accumulation chamber 5 through a dust collecting bin 6 and then back to the coke-cooler plenum 2 through an exhaust fan. Excess gas from the vent of the accumulation chamber 4 is cleaned from dust and then fed through a pipe to a raw gas pipe 11, after which it is further cleaned in a mixture with raw gas from dust, ammonia and resinous substances.
