Abstract

The invention discloses a heat-transfer equipment performance experimental facility to solve the problem that a present experimental facility cannot perform experiments on heat transfer performance, corrosion resistance and mechanical property of an air preheater for gas-gas transfer. The heat-transfer equipment performance experimental facility is provided with parts such as a cylindrical shell (10), a combustor (12), a gas distributor (9), a transition section (26), a flue gas duct (27), a sulfur dioxide gas-bomb (17) and the like. The gas distributor divides an inner cavity of the cylindrical shell into a first cavity (13) and a second cavity (24). An inlet air tube (61), the second cavity, a flue gas duct and an outlet air tube (62) are respectively connected with a data acquisition unit for measuring gas temperature, pressure and flow. Each data acquisition unit is connected with a data processor (8) through respectively data line (4). The heat-transfer equipment performance experimental facility is mainly used for performing experiments on performance of a tubular heating furnace's air pre-heater for gas-gas transfer in the industries of petroleum refining and petrochemical engineering.

Description

technical field [0001] The invention belongs to the technical field of heat transfer equipment, and relates to a performance experiment device for heat transfer equipment. Background technique [0002] In petroleum refining, petrochemical and other industries, the air preheater of the heating furnace (mainly the tubular heating furnace) is the main equipment for the heating furnace to recover the waste heat of the flue gas and improve the thermal efficiency, and it is also a commonly used equipment. In recent years, with the deepening of energy saving and emission reduction work in enterprises, in order to recover more flue gas waste heat, it is required to reduce the temperature of flue gas discharge as much as possible, and higher requirements are put forward for the heat transfer performance of air preheater. The reduction of flue gas discharge temperature is also restricted by low-temperature acid dew point corrosion factors. At present, the flue gas acid dew point temp...
