T type finned tube reboiler is a floating head type shell and tube for a new form of heat exchanger is model, boiling heat transfer equipment, fill our country boiling heat transfer equipment of a blank. It uses the non cutting rolling process of a dense, spiral shaped T fin tube (referred to as T type fin tube) instead of ordinary light tube, so that the liquid in the T type finned tube spiral channel wall surface boiling, due to the high efficiency of liquid film evaporation in the channel, in a wide range of heat flux, can keep the media in a nuclear boiling state, so that the heat transfer coefficient is greatly improved, in the process of high speed can also prevent fouling.
Compared with ordinary light tube heat exchanger, the heat transfer efficiency of T type finned tube is not only has high heat transfer efficiency, but also has the advantages of low temperature, high critical heat load, stable operation and high elasticity.
The T-type finned tube compared with that of the smooth tube heat transfer efficiency increase is larger than or equal to three times, saving heat transfer area is more than or equal to 30%. The pressure rating: 1.0 ~ 6.4Mpa T - shaped fin tubes material: No. 10, stainless steel, 08Cr2AlMo, 12Cr2AlMoVE.
Scope of application: applicable to the petroleum chemical, energy and other industrial fields, the heat transfer in the shell side of the case. Do not apply to the housing containing solid dust and easy medium coke.
