Description

Описываемый способ вл етс разработкой способа работы газогенератора противоточного процесса в авт. св. № 69623.The described method is the development of a method of operating a gas generator of a countercurrent process in ed. St. No. 69623.

Часть газов из зоны пиролиза с температурой 800-850°С направл ют в смеситель-эжектор, где они смешиваютс с холодным газом или обратным газом, прошедшим камеру сушки. Смесь газов, нагрета до 250-350°С, поступает в камеру сушки в противотоке к движению топлива, покида ее при 150°С. За счет тепла газов топливо нагреваетс до 200°С и с этой температурой поступает в камеру полукоксовани и пиролиза.Part of the gases from the pyrolysis zone with a temperature of 800-850 ° C are sent to the mixer-ejector, where they are mixed with cold gas or return gas that has passed through the drying chamber. The mixture of gases, heated to 250-350 ° C, enters the drying chamber in countercurrent to the movement of the fuel, leaving it at 150 ° C. Due to the heat of gases, the fuel is heated to 200 ° C and with this temperature enters the semi-coking chamber and pyrolysis.

Газы генераторного процесса, имеюш.ие температуру около 900°С. и часть газов пиролиза поступают в топку-эжектор, где за счет частичного сгорани в токе кислорода нагреваютс до 1000-1200°С. С этой температурой газы поступают в камеру полукоксовани и пиролиза.The gases of the generator process have a temperature of about 900 ° C. and part of the pyrolysis gases enter the ejection furnace, where, due to partial combustion in a stream of oxygen, they are heated to 1000-1200 ° C. At this temperature, the gases enter the chamber of semi-coking and pyrolysis.

Claims

1. Method of operation of the gas generator of the countercurrent process according to ed. St. 69623, characterized in that the thermal preparation of the fuel prior to semi-coking is carried out at temperatures of 250-350 ° C with a mixture of part of the pyrolysis gases and cold gases after the drying zone.

2. The method according to claim 1, in accordance with the fact that the generator and pyrolysis gases are partially burned out in an ejector furnace in a stream of oxygen and then with a temperature of about 1200 ° C, are directed to the semi-coking zone.

3. The method according to claim 2, differs by the fact that the generator and pyrolysis gases are mixed with the gas after the drying chamber to a mixture temperature of 500 ° C and then blow through the fan through the furnace, where they are partially burned in a stream of oxygen and heated steam. up to 1200 ° C in the semi-coking zone.
