According to news from May 21, 2025, **information from the Intellectual Property Office shows that Sinochem Saiding Coking (Shanxi) Engineering Technology Co., Ltd. has obtained a patent titled “A Coking Oven Combustion Chamber Structure with a Dual-Symmetrical Flue Structure.” The approval notice number is CN222886728U, and the application was filed in July 2024. The patent abstract indicates that this utility model belongs to the field of coke ovens, and specifically relates to a combustion chamber structure for coke ovens featuring a dual-symmetrical flue structure. The interior of the furnace combustion chamber is divided into multiple vertical fire channels by alternately arranged air-flow-directional partition walls and opposite-air-flow-direction partition walls. Crossing holes and circulation holes are provided on the opposite-air-flow-direction partition walls, while combustion-supporting air channels and lean gas channels are installed within the air-flow-directional partition walls; these two types of channels are each connected to the regenerator cells through inclined channels. Additionally, multiple combustion-supporting air outlets and multiple lean gas outlets, which are connected to these two channels, are arranged along the vertical direction on both sides of the air-flow-directional partition walls, thereby enabling precise control over air flow distribution. This utility model features a dual-symmetrical flame channel design, in which a single channel supplies gas to two adjacent flame channels – a concept that is unique among coke ovens of this type in China. The rational layout of the various sections ensures a more even distribution of air flow within the combustion chamber of the coke oven, thereby improving the uniformity of heating from top to bottom and reducing the level of nitrogen oxides in the exhaust gases. According to Tianyancha data, Zhonghua Chemicaiding Coking (Shanxi) Engineering Technology Co., Ltd. was established in 2020 and is located in Changzhi City; it is a company that operates primarily in the construction and installation sector.
