    • The present technology is generally directed to horizontal heat recovery and non-heat recovery coke ovens having monolith crowns. In some embodiments, an HHR coke oven includes a monolith crown that spans the width of the oven between opposing oven sidewalls. The monolith expands upon heating and contracts upon cooling as a single structure. In further embodiments, the crown comprises a thermally-volume-stable material. The crown may be an oven crown, an upcommer arch, a downcommer arch, a J-piece, a single sole flue arch or multiple sole flue arches, a downcommer cleanout, curvilinear corner sections, and/or combined portions of any of the above sections. In some embodiments, the crown is formed at least in part with a thermally-volume-stable material. In further embodiments, the crown is formed as a monolith (or several monolith segments) spanning between supports such as oven sidewalls. In various embodiments, the monolith and thermally-volume-stable features can be used in combination or alone. These designs can allow the oven to be turned down below traditionally feasible temperatures while maintaining the structural integrity of the crown.
    • 本技术通常涉及具有整体冠的水平热回收和非热回收焦炉。 在一些实施例中,HHR焦炉包括跨越相对的炉侧壁之间的炉的宽度的整块表冠。 整体在加热时膨胀并且作为单一结构在冷却时收缩。 在另外的实施方案中,冠包含热容量稳定的材料。 冠部可以是烤箱冠,升压拱,降管拱,J形件,单个底部烟道拱形或多个底部烟道拱门,降液器清洁,曲线拐角部分和/或上述任何一个的组合部分 部分。 在一些实施例中,冠部至少部分地形成有热量 - 体积稳定的材料。 在另外的实施例中,冠部形成为跨越诸如烤箱侧壁的支撑件之间的整料(或多个整料段)。 在各种实施方案中,整体和热体积稳定的特征可以组合使用或单独使用。 这些设计可以使烤箱在传统可行的温度下降低,同时保持表冠的结构完整性。

    • This invention comprises a complete arrangement of ovens, underflues, cooling air ducts under the oven, the feeder flue, to control dampers in the feeder flues, the common flues, the charge car operating over the ovens the ram car operating on one side of the ovens and the hot coke car operating on the other side of the ovens, the oven doors, the door opening/closing mechanism, the coal bin tower with the weighbridge, the quench tower and the feed of the flue gases to boilers of the power plant. The oven is a specially designed structure made of various qualities and shapes of refractory bricks designed to withstand the high temperatures. The combustion is controlled by allowing air in and the hot waste gases are led to a common flue refractory lined inside to withstand the high temperature. The waste gases are led to the boiler for producing steam and electric power in a turbine/generator for energy recovery or alternatively led to an oven stack of sufficient height to maintain a draft in the oven to sustain the coking process.

    • The present invention relates to a process for the preparation of coke from coal in a coke oven, to a coke oven and to the use of this coke oven to prepare coke from coal. The process for the preparation of coke from coal in a heat recovery coke oven comprises at least the following steps: (A) Providing coal (1) in the at least one primary chamber of the coke oven, (B) At least partial combustion of gas released from the coal in the at least one primary chamber by introducing air through the at least one moiety for providing air (4) to the at least one primary chamber, and carbonization of the coal to obtain coke at a temperature T1, (C) Combustion of the remaining gas released from the coal in the secondary chamber (6) at a temperature T2, wherein this remaining gas has been guided to the at least one secondary chamber (6) through the connection (5) between the at least one primary chamber (2) and the at least one secondary chamber (6), by introducing air through the at least one moiety for providing air (8) to the at least one secondary chamber and (D) Removing the off-gas obtained from steps (B) and (C) through the at least one collector (9), wherein temperature T2 is measured in predefined time intervals during steps (B), (C) and (D) and the at least one moiety for providing air (60) to the at least one secondary chamber is adjusted depending on a comparison of T2 with a value SP2 calculated from T2 of the foregoing time interval, wherein the first value SP2 is predefined at the beginning of step (B). According to a preferred embodiment of the process according to the present invention, SP2 is calculated according to the following method: The first value of SP2 is set by the operator. After certain a certain time interval, for example 20 minutes, temperature T2 is measured and the central processing unit calculates if the difference of SP2 and T2 (SP2 - T2) has increased or decreased during the time interval. For example, if SP2 - T2 has increased more than 2°C, SP2 is recalculated and the new SP2 is the old SP2 + 5 to 14 °C. Further, if SP2 - T2 has decreased more than 1 to 5 °C, SP2 is recalculated and the new SP2 is the old SP2 - 10 to 25 °C.
