摘要： The pressure in the coking chamber of a coke oven is held at about atmospheric pressure, and the temperature at the opposite longitudinal ends of the combustion chamber is independently controlled. Fuel gas is supplied to hold the temperature at the opposite longitudinal ends to be at least about 1000 °C separately from a main burner for the combustion chamber, and the pressure in the coking chamber during the first part of coking is kept in a range from 5 mmH 2 O below atmospheric to 10 mmH 2 O above atmospheric pressure. This allows efficient coke production even with low moisture content coking coal, and coal crumbling near the oven doors is not a problem. The process is typically carried out in a coke oven having a pressure control system for each coking chamber including plural piping devices for supplying a pressure fluid and switching valves for selectively applying the pressure fluid to the nozzle in the rising pipe through any selected one of the piping systems. The fluid pressure applied to the nozzle and the pressure in the coking chamber are preferably changed over time based calculated relationships between carbonization time, coking chamber pressure, and fluid pressure applied to the nozzle.
摘要翻译：焦炉的焦化室中的压力保持在大气压下，并且独立地控制燃烧室的相对纵向端部处的温度。供给燃料气体以将相对的纵向端部的温度与用于燃烧室的主燃烧器分开地保持至少约1000℃，并且在焦化的第一部分期间焦化室中的压力保持在 5毫米汞柱，低于大气压至大气压10mmHg。这样即使使用低含水量的焦煤也能实现有效的焦炭生产，并且在炉门附近的煤粉碎不是问题。该方法通常在具有用于每个焦化室的压力控制系统的焦炉中进行，所述焦化室包括用于供应压力流体的多个管道装置和用于选择性地将压力流体施加到上升管中的喷嘴的任何选定的一个管道系统。施加到喷嘴的流体压力和焦化室中的压力优选随着时间的推移，碳化时间，焦化室压力和施加到喷嘴的流体压力之间的计算关系而改变。
