VERTICAL CYLINDRICAL CONVECTION TUBULAR FURNACE FOR THE SMALL TONNAGE OIL-PROCESSING PRODUCTIONS Russian patent published in 2007 - IPC C10G9/00 

FIELD: oil-refining industry; convection tubular furnaces for heating of the hydrocarbon raw.

SUBSTANCE: the invention is pertaining to the field of oil-refining industry, to the convection tubular furnaces for heating of the hydrocarbon raw due to burning the fuel. The vertical cylindrical convection tubular furnace contains: the combustion chamber (3) with the burner (1), the lined body (4) and the located in it tubular pipe coil (5), the convection chamber (8), the cylinder (10) for feeding the hot gases into the convection chamber (8) and the smoke flues (17). The combustion chamber (3) is supplied with the cylindrical prechamber (2) arranged tangentially to it. The tubular pipe coil (5) is installed coaxially to the cylinder (10) for the hot gases feeding and consists of two parts - the internal part (6) and the external part (7), and is supplied with the hydrocarbon raw feeding collector (11), which is connected to the both parts of the tubular pipe coil (5), and also to the collector (12) for withdrawal of the raw hot flows to the outlet. The invention reduces the toxicity and smoking of the spent gases and the hydraulic resistances at the hydrocarbon raw movement in the tubular pipe coil, improves the conditions of the furnace maintenance and repairs.

EFFECT: the invention ensures reduction of the toxicity and smoking of the spent gases and also the hydraulic resistances at the hydrocarbon raw movement in the tubular pipe coil, improvement of the conditions of the furnace maintenance and repairs.
