Process for reforming relay heat of heating furnace and equipment thereof

Abstract

The invention discloses a process for reforming relay heat of a heating furnace and equipment thereof. The process for reforming relay heat of the heating furnace is characterized in that a reformed radiation chamber and a relay heating furnace are integrated together to form a heating system; process mediums to be heated in a reforming device are heated together, and the part with deficient heat adopts relay heat. The equipment for reforming relay heat of the heating furnace mainly comprises the radiation chamber, a floor convention chamber, an air preheater, a relay heating furnace, a draft blower, a draft fan and a chimney, the parts are connected through pipelines; the upper part of the radiation chamber is provided with a tipburn burner; the floor convention chamber is positioned between two radiation chambers; three relay heating furnaces and the air preheater are arranged in front of the radiation chamber in parallel; the draft fan and the draft blower are respectively positioned on two sides of the air preheater; and the chimney is arranged in front of the draft fan. The process and the equipment can reduce consumption of fuel oil or fuel gas, and reduces pressure of a steel structure and steel consumption.

Description

technical field [0001] The invention belongs to a reforming furnace heating process and its equipment used in petrochemical enterprises, in particular to a reforming furnace relay heating process and equipment, which is a reforming device for large-scale reforming A combined heating furnace process and its equipment that require the combination of independently heated process media. Background technique [0002] In petrochemical enterprises, the reforming unit is an important means of producing high-quality gasoline or providing raw materials for the chemical industry. In recent years, my country has introduced a full set of technologies and built dozens of reforming units. The reaction heating furnaces of these reforming units (mostly Four-in-one, several three-in-one) are all natural ventilation, side burning or bottom burning, the convection chamber generates steam to recover waste heat, the convection chamber is set on the top of the radiation chamber, and the chimney is ...

AI Technical Summary

Problems solved by technology

120×10 4 The main steel section of the t / a reforming four-in-one heating furnace is H900 wide wing edge I-beam, the pressure on the steel structure is very high, and a lot of steel is wasted

[0010] Taking the current side-fired furnace as an example, if the processing capacity is increased to 200×10 4 t / a, there are not only structural problems in the engineering design of the four-in-one heating furnace, but also uneven heat transfer of the furnace tube due to side firing
