<p>PURPOSE:To carry out safely the charging of coke, by feeding part of a inert cooling gas to a coke charging hopper, mixing it with a combustible gas generated in the hopper, mixing the mixture with air and burning the combustible gas in a catalytic reactor. CONSTITUTION:Coke 1 to be quenched is fed through a coke charging hopper 2 to a grate 4 where heat exchange between the coke 1 and a cooling inert gas 5 is conducted to quench and cool the coke, and the coke is then discharged out of the quenching equipment. The inert cooling gas 5 heated by heat exchange with the coke 1 is cooled in a waste heat boiler and circulated by means of circulating fans 7, 7', 7'' etc. to use it. Part of the inert cooling gas 5 circulated is taken up by means of a blower 35, fed to the hopper 2 and mixed with a combustible gas G generated in the hopper 2. The gas mixture is taken out of the hopper 2, mixed with air 33 and introduced into a catalytic reactor 32 to burn the combustible gas G.</p> |
