Abstract

The invention discloses a tubular heating furnace with a cruciform layout, and belongs to the technical field of petroleum refining equipment. The tubular heating furnace comprises a furnace lining, heaters and a furnace tube; the main body of the furnace lining is of a cylindrical structure, the furnace tube is arranged in the furnace lining in a circumference mode, the interior of the circumference is the cruciform center line layout, and the circumference is divided into four equant areas by a cruciform center line; and the heaters are distributed at the bottom of the furnace lining corresponding to the four areas. According to the tubular heating furnace with the cruciform layout, the problem that a medium in a furnace tube is prone to coking can be solved, meanwhile, the utilization rate of the furnace tube can be greatly improved, and demands of subsequent capacity expansion of the heating furnace are met.

Description

technical field [0001] The invention relates to a cylindrical tube heating furnace in the form of cross-shaped furnace tube arrangement. It belongs to the technical field of petroleum refining equipment. Background technique [0002] Tube heating furnace is a process heating furnace used in petroleum refining, petrochemical and chemical industry, chemical fiber industry, coal chemical industry, and coal to oil. phase medium. Moreover, these media are flammable and explosive substances, which are dangerous and have harsh operating conditions. The way of heating is direct fire, only burning liquid or gas fuel, and requires long-term continuous operation. [0003] At present, the furnace tube layout of the tube heating furnace is relatively simple, especially for small and medium-sized load heating furnaces, which generally adopt vertical cylindrical furnaces, and generally the tubes of cylindrical heating furnaces are set against the wall, which cannot effectively radiate t...
