Abstract: Pressure vessel has a development trend for super magnitude and super thickness in the current petrochemical industry. How to improve heating capacity of single fuel oil combustor holds the key to heating processing capacity. HT-Y9.1000 fuel oil PWHT Commanding machine adopts diesel internal combustion heating method on the site to make overall heat treatment for pressure vessels. It has a number of systems for temperature control, adjustment of the burner, variation of frequency, digital calculation, temperature inspection and anti-interference, with the functions to improve output power of the burner, automatically control the temperature, keep the burner in stable operation and resist interferences. The heat processing capacity of the equipment can reach 1200L/h while the control precision is 0.3 grade and the maximum heat processing weight 700 tons. Successfully used in a number of projects at home, this equipment can automatically control the burner, significantly improve the heating capacity of single burner and effectively keep the temperature control precision. It is suitable for super-heavy ball and large-scale pressure vessels for overall heat treatment.

Key words: fuel oil, overall heat treatment, equipment, large-scale pressure vessel
