The blended coal delivered from the coal preparation workshop is loaded into the coal tower; the coal loading vehicle retrieves coal from the tower according to the operation plan, and after measurement, it is fed into the carbonization chamber. In the carbonization chamber, the coal undergoes high-temperature dry distillation over a coking cycle to produce coke and raw gas. Once the coke in the carbonization chamber has matured, it is pushed out using a coke pusher; it is then guided into the coke quenching car by a coke stopper car, and an electric locomotive pulls the coke quenching car into the quenching tower for **coke quenching**. After coking is stopped, the coke is unloaded onto a cooling bed; after cooling for a certain period of time, it is sent to the coke screening section, where it is sorted by grade and stored for shipment. The raw gas generated during the carbonization process of coal in the carbonization chamber collects in the space at the top of the chamber, and then enters the gas collection pipe via the rising pipe and bridge pipe. The raw gas at around 700°C is cooled to about 90°C by spraying it with ammonia water inside the bridge tube. Tar and other substances in the waste gas are also condensed at the same time. Gas and the condensed tar, along with ammonia water, are sent to the gas purification workshop through the coal gas suction pipe. Coke oven gas for heating the coke ovens is introduced via external pipelines overhead. After preheating, the coke oven gas is sent to the basement of the coke oven, where it is introduced into the bottom of the combustion chamber’s flame channel through lower nozzles, where it mixes with the air entering via the exhaust gas exchange valve to undergo combustion. The exhaust gas after combustion enters the downward-flowing flue through the opening at the top of the vertical flue, then passes through the regenerator, where part of the sensible heat in the exhaust gas is recovered. After that, it flows through the small flue, the exhaust gas exchange valve, the branch flues, the main flue, and is finally discharged into the atmosphere via the chimney.
