Device for supply of combustion air or gas, which influences coking of bituminous coal, to upper zone of furnaces

FIELD: metallurgy. SUBSTANCE: device for supply of combustion air of coke furnace gas to a coking chamber of the coke furnace with or without heat utilisation is proposed. Upper part of coke furnace is equipped with holes, through which primary air is supplied to it, and lower part of coke surface is equipped with holes, through which it is heated with secondary air. The furnace is equipped with the so called down coming gas lines that allow directing the product of partial gas combustion inside the furnace for combustion by means of secondary air to lower furnace zone - in side furnace wall above the door zone or in upper door part there is one or more non-controlled holes made from fire-resistant material and intended for direction of some part of primary air, and in upper furnace zone there are additional air supply channels with suction connection pipes, which are led through upper furnace surface and equipped with controlled locking elements. With that, additional primary air is passed via the above channels with suction connection pipes. A non-controlled hole above the furnace door or in the furnace door represents a nozzle-like device made from fire-resistant aluminous or siliceous oxide material or from siliceous-aluminous oxide material, and the above hole converges in its cross section in flow direction in the pipe; as a result, higher flow velocity appears in the pipe. Besides, a method for supply of combustion air of gas in a coking chamber of coke furnaces is proposed. EFFECT: control of air supply, which leads to uniform coke production. 28 cl, 4 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) 2 500 785 (13) C2 (51) МПК C10B C10B C10B C10B C10B 15/02 15/00 21/10 21/22 29/00 (2006.01) (2006.01) (2006.01) (2006.01) (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (21)(22) Заявка: 2010113356/04, 22.08.2008 (24) Дата начала отсчета срока действия патента: 22.08.2008 (72) Автор(ы): КИМ Рональд (DE), ШУМАХЕР Ральф (DE) ...

Method of operating a coke oven battery

Regenerative changeover of a coke oven battery is designed for operation according to a method wherein each regenerative half period is broken down into a time when gas is supplied at a constant pressure to the burners in heating flues and a time when no gas is supplied. A final control facility acts on the regenerative changeover facility to enable the regenerative half period to be broken down into these two time periods. A controller is responsive to variations in gas properties, such as the calorific value, density, humidity and temperature, to bring about operation of the final control element so that the heating time and the pause in every regenerative half period have values such that the heat supplied to the battery in each half period remains constant.
