Patent number: 11577199Abstract: Provided is a method for desulphurizating and denitrating a flue gas in an integrated manner based on low-temperature adsorption. The method includes: decreasing a temperature of the flue gas below a room temperature by using a flue gas cooling system; removing moisture in the flue gas by using a dehumidification system; sending the flue gas to a SO2 and NOx adsorbing column system; and simultaneously adsorbing SO2 and NOx of the flue gas with a material of activated coke, activated carbon, a molecular sieve or diatom mud in the SO2 and NOx adsorbing column system to implement an integration of desulphurization and denitration of the flue gas based on the low-temperature adsorption. With the present method, SO2 and NOx of the flue gas can be adsorbed simultaneously in an environment having a temperature below the room temperature.Type: GrantFiled: October 14, 2021Date of Patent: February 14, 2023Assignees: CHINA HUANENG GROUP CO., LTD, HUANENG CLEAN ENERGY RESEARCH INSTITUTEInventors: Shiqing Wang, Shisen Xu, Shiwang Gao, He Zhao, Minhua Jiang, Ping Xiao, Bin Huang, Hongwei Niu, Jinyi Wang, Lianbo Liu, Dongfang Guo

Patent number: 9488370Abstract: The disclosure provides an arrangement structure suitable for an inverted pulverized coal boiler with ultra-high steam temperature steam parameters, including a hearth, wherein the hearth is communicated with a middle uplink flue, and the top of the middle uplink flue is communicated with that of a tail downlink flue. In the structure, the hearth is connected with the middle uplink flue by a hearth outlet horizontal flue at the bottom, so that the high-temperature gas is drained to a low elevation and then flows upwards through the middle uplink flue; a final heating surface may be arranged at the low position of the hearth outlet horizontal flue and the middle uplink flue so as to reduce the length of the high-temperature steam pipeline between the final heating surface and the steam turbine, lower the manufacturing cost of the boiler as well as the frication and radiation loss of the pipe.Type: GrantFiled: November 18, 2011Date of Patent: November 8, 2016Assignee: Huaneng Clean Energy Research InstituteInventors: Minhua Jiang, Ping Xiao, Jianzhong Jiang, Li Zhong
