Abstract

A pipe furnace, which can be used for heating of technological products, in particular, for heating of oil and oil products in mini-oil-refining installations. The furnace contains vertical cylindrical body of constant diameter with radiation zone and convection zone, located over the radiation zone; smoking pipe, located over the convection zone; burner, located at the bottom of the furnace; pipe battery, made in a form of cylinder of constant diameter, shading the inner surface of zones of radiation and convection and installed in alignment in the body of furnace; dissector, installed in alignment in pipe battery from the side of convection zone. At that pipe battery along its whole length is made in a form of spiral top hat cylinder, the dissector is made in a form of cylindrical insert with superior and inferior bottom of predominantly conic or other streamlined form and is fixed on tension bars to the cover with ability of regulation of length of tension bars; and the height of dissector is defined by the basic height if convection zone, diameter – by providing a sought annular gap towards the inner diameter of spiral coil. The using of such furnace enables to decrease the heat loss with furnace gases and to simplify the conducting of assembling and dismantling and repair operations.
