(S) ТРУБЧАТАЯ ПЕЧЬ(S) TUBULAR OVEN
Изобретение относитс к трубчатым печам и может быть использовано в нефт ной, газовой и нефтехимической промышленности. Наиболее близкой к предлагаемой п технической сущности и достигаемому результату вл етс трубчата печь, содержаща огнеупорную трубчатую футеровку , радиантную и конвекционную камеры, воздухоподогреватель, соединенный с воздуховодами, и плоскофакельные форсунки l3Недостаток известной трубчатой печи состоит в относительно низкой производительности, значительных экс плуатационных затратах. Цель изобретени - повышение производительности печи, снижение капитальных и эксплуатационных затрат. Поставленна цель достигаетс тем что в известной трубчатой печи, соде жащей огнеупорную футеровку, радиантную и конвекционную камеры, воздухо подогреватель, соединенный с воздухо водами, и плоскофакельные форсунки, воздухоподогреватель выполнен пластинчато-ребристым , воздуховоды выполнены в виде рекуперативного короба, покрывающего поверхность конвекционной и.радиантной камер, пластины воздухоподогревател расположены наклонно , образу между собой- каналы трапециевидной формы переменного сечени по ходу дымовых газов и посто нного сечени по ходу воздуха. На фиг.1 схематично изображена печь, поперечный разрез; на фиг.2 каналы воздухоподогревател . Трубчата печь содержит радиантную камеру 1, конвекционную камеру 2, воздухоподогреватель 3, рекуперативный короб , огнеупорную футеровку 5 со сквозными отверсти ми 6 и регулирующими шиберами 7. В поду печи расположены плоскофакельные форсунки 8.. Печь работает следующим образом. Холодный воздух в результате разрежениц в печи и за .счет незначитель3 9321714The invention relates to tube furnaces and can be used in the oil, gas and petrochemical industries. Closest to the proposed technical essence and the achieved result is a tubular furnace containing a refractory tubular lining, radiant and convection chambers, an air heater connected to the air ducts, and flat nozzles l3 The disadvantage of the known tubular furnace is relatively low productivity, significant ex- pressurized masters. The purpose of the invention is to increase the productivity of the furnace, reducing capital and operating costs. The goal is achieved by the fact that, in a known tube furnace containing a refractory lining, radiant and convection chambers, an air preheater connected to the air and flat-jet nozzles, the air preheater is plate-ribbed, the air ducts are made in the form of a recuperative duct, and the cover has a cover and a cover that has a cover and a cover. the radiant chambers, the plates of the air heater are arranged obliquely, forming between themselves the channels of a trapezoidal shape of variable cross section along the flue gases and constant this section along the air. In Fig.1 schematically shows a furnace, a cross-section; in Fig.2 channels air heater. The furnace tube contains a radiant chamber 1, a convection chamber 2, an air heater 3, a recuperative box, a refractory lining 5 with through holes 6 and regulating gates 7. Flat furnace nozzles 8 are located in the furnace. The furnace works as follows. Cold air as a result of dilutions in the furnace and at the expense of a negligible3 9321714
