Abstract

PURPOSE: To keep boiler function even when coke can not be cut down from lower part and to prevent the residence of gas in a furnace, by a method wherein in a cooling gas-forced circulation system the downstream side of a waste-heat boiler is connected to the top part of a furnace, and a by-pass pipe line is provided which is opened as the occasion demands.
CONSTITUTION: The downstream side of a waste-heat boiler 25 is connected to the top part of a quenching furnace 25, and a by-pass pipe line 43 is provided which is opened as the occasion demands. When the supply of cooling gas becomes impossible by a trouble, an on-off valve 45 is adjusted and an on-off valve 44 is opened. The cooling gas is passed through the by-pass pipe line 43 into a duct 42, and then into the top part 38 of the furnace. Then the gas is contacted with red hot coke which is placed within a prechamber 25A and is not quenched under normal conditions. The gas heated to a high temperature is forcedly recycled through a throughhole 30, a circular gas 29, a duct 32, a waste-heat boiler 31 and a blower 34 to the by-pass pipe line 43. In this way, the same quantity of heat as during normal operation can be supplied to the waste-heat boiler 31. Since the recycling of the gas is continued, the prechamber is prevented from being filled with combustion gas.
