PurposeTubular furnaces are designed for high-temperature heating of oils and oil products in refining processes. Hydrocarbon gases, water, inert gases and other medium can be heated if required.
Heating furnaces can be equipped with steam heaters or processing water steam generators, occupying max. 20% of total heating area. The furnace consists of radiation chamber, equipped with radiant coils, burners, sight ports, manholes (with doors) for maintenance, explosion ports and fire control unit; convection chambers with convective pipe bundles and heat-utilizing surfaces (steam heaters, economizers, air preheaters, steam generators); - gas flues and stack with gate-valves. Furnace body has internal refractory lining and heat insulation, preventing heat losses. Furnaces are equipped with primary control units and devices regulating raw material heating. There are emergency blockings to provide safe operation of the equipment. Furnaces are completed with service platforms, ladders and access boards.
Tubular furnace CS
Cylinder furnaces with wall arrangements of coil pipes in radiation chamber of free vertical flare combustion of combined fuel.
Combined burner are arranged in a furnace hearth. The single-row tube waterwalls are mounted on walls of radiation chamber. Combustion gas is exhausted through smoke stack and gas collector.
There are two design options for these furnaces: radiation (w/o convection chamber) and radia-tion-convection (with convection chamber).
For radiation furnaces code the R letter is added. Radiation chamber pipes could be ar-ranged vertical, horizontal or spiral.
