Beschreibung
Zusammenfassung:	FIELD: oil processing industry branches. SUBSTANCE: furnace includes radiant and convective coils, air heater and twin portion made of elliptical tubes. Small axes of sections of radiant tubes are arranged normally relative to lining; large axes of sections of convective tubes and air heater are arranged along flow of flue gases. Perforated false bottom is placed over furnace hearth. Inner layer of lining is made of material with high heat conductivity. Uniformly heated radiant tubes have increased factors of heat emission by irradiation in radiant chamber and heat emission by convection inside and outside tubes of both coils and air heater. EFFECT: enhanced heat generation, lowered metal consumption in furnace, increased service life period of coils due to reduced coke formation, lowered content of harmful outbursts and exhaust flue gases due to decreased temperature of burning fuel torches. 4 dwg
