お（31）はブリードガスである。(Prior Art) Dry coke extinguishing equipment is a method of extinguishing and cooling calcined red-hot coke with gas to give heat from the coke to obtain high-temperature gas, while removing the obtained high-temperature gas. A series of plants that are used for power generation, etc. by guiding them to a heat utilization boiler. The conventional example of this coke dry fire extinguishing equipment will be explained with reference to FIG. 3. (1) Hopper,
(3) red hot coke, (4) hot exhaust gas conduit,
(29) is a heat exchanger, (9) is a cyclone, (12) is a cooling gas conduit, (30) is a plurality of pumps, (28) is a plurality of cooling chambers, and (5) is a circulating pallet. The red hot coke (3) is supplied from the hopper (1) onto the pallet (5) and passes through each cooling chamber (28). At this time, the cooling gas that has passed through the heat exchanger (29) as an extra-fluid fluid and is cooled by the intra-fluid fluid passes through the cyclone (9) → the cooling gas conduit (12) → the pump (30) to the cooling chamber. Led to (28),
The red hot coke (3) is cooled by passing through the pallet (5) and the red hot coke (3) moving in the cooling chamber (28) from below to above. After that, the pallet (5) and the red hot coke (3), which are guided to the next cooling chamber (28) through the next pump (30) and are moving in the cooling chamber (28) as above, are moved from the bottom to the top. To cool the red hot coke (3). The exhaust gas that has passed through the last cooling chamber (8) and has risen to a high temperature enters the heat exchanger (29) as an external fluid via the exhaust gas conduit (4), heats the internal fluid, and cools itself. ， Exit again from the heat exchanger (29). On the other hand, the heated external fluid (steam) is sent to a turbine for a generator or the like and used for driving the turbine. Note that (31) is bleed gas.
