    • 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.
    • 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。

    • Heating system for regenerative coke oven batteries heatable with rich, and/or lean or mixed gas, comprising vertical flues grouped in pairs connected to regenerators for preheating the air or, in lean gas operation, the lean gas or mixed gas. The invention comprises a combination of the following features: a) The combustion air is introduced through outlet openings arranged at at least three different heights in each flue. One outlet opening at the base of the flow is connected directly to the regenerators and the outlet openings arranged above the first are connected to the regenerators via hollow connecting passages arranged in the connecting walls or via separate passages. b) The regenerators for preheating the air are divided in the longitudinal direction of the oven. One part is connected to the outlet openings at the base of the flue, the other part is connected to the hollow connecting passages or to the separate passages, and the volumes of air for the two parts can be adjusted separately from outside. c) The outlet openings above the bottom of the flue are provided with externally adjustable sliding blocks for adjusting the distribution of air. d) Closable openings (cross-flow openings) which direct the internal flue gas flow are arranged at the base of the flue in the connecting wall between the upward-conducting and downward-conducting flues.
    • 用于富含和/或贫气或混合气体可加热的蓄热式焦炉电池的加热系统,包括成对分组的垂直烟道,其连接到再生器用于预热空气或在贫气操作中稀燃气体或混合气体。 本发明包括以下特征的组合:a)燃烧空气通过设置在每个烟道中至少三个不同高度处的出口开口引入。 流体底部的一个出口开口直接连接到再生器,布置在第一个出口之上的出口开口通过布置在连接壁中的中空连接通道或经由分开的通道连接到再生器。 b)用于预热空气的再生器在烘箱的纵向上分开。 一部分连接到烟道底部的出口,另一部分连接到中空连接通道或连接到单独的通道,并且两部分的空气体积可以与外部分开调节。 c)烟道底部上方的出口开口设有外部可调的滑块,用于调节空气分布。 d)引导内部烟道气流的闭合开口(横流开口)布置在烟道底部的上导流道和下导流道之间的连接壁上。
