Isobaric type diesel combustor

Abstract

An isobaric type diesel combustor comprises an inner compressed air tube and an outer oil tube sleeved outside the inner compressed air tube, wherein two ends of the inner compressed air tube extend out of the outer oil tube; one end of the inner compressed air tube is connected with a diameter-variable inner compressed air tube, the diameter of the diameter-variable inner compressed air tube is larger than that of the inner compressed air tube, and an oil passing hole is arranged on the diameter-variable inner compressed air tube; one end of the outer oil tube is connected with a diameter-variable outer oil tube sleeved outside the diameter-variable inner compressed air tube, and the diameter of the diameter-variable outer oil tube is larger than that of the outer oil tube; sealing end covers are arranged on the end portions of the diameter-variable inner compressed air tube and the diameter-variable outer oil tube, and ejecting holes communicated with the diameter-variable inner compressed air tube are arranged on the sealing end covers. The isobaric type diesel combustor is simple in structure, easy to control due to the fact that no oil gas proportion adjusting valve is installed and capable of stably supplying compressed air to atomize diesel, and enables the diesel atomizing effect to be stable, an incinerator is stable in combustion, protective halt and flameout of the incinerator can be prevented, temperature fluctuation of the incinerator is small, and the combustor is safe and reliable to use.

Description

technical field [0001] The invention belongs to the technical field of burners for incinerators in the cigarette industry, and in particular relates to an equal-pressure diesel burner. Background technique [0002] CO in cigarette manufacturers 2 On the cut tobacco expansion line, the incinerator uses diesel as fuel, and the diesel is mixed with compressed air in the burner and then combusted. The atomization effect is very important for the combustion of diesel. The monitoring of the incinerator and the control principle of the diesel burner are as follows: when the system has the ignition conditions, the liquefied gas that is easy to burn is ignited first, and the flame of the liquefied gas after combustion provides ignition for the combustion of the atomized diesel oil. Once the ignition is successful, the liquefied gas Under the control of PLC, the liquefied gas control valve is automatically turned off; the diesel atomized by compressed air is normally burned in the in...

AI Technical Summary

Problems solved by technology

If the oil pressure changes too much, the mechanical oil-air proportional regulating valve cannot keep up with the change of oil pressure, and the oil-gas proportional regulating valve fails, etc., will cause poor atomization effect of diesel oil, resulting in changes in the length and brightness of the flame of diesel combustion. Make the flame detection probe unable to detect the existence of the flame, eventually leading to the occurrence of protective shutdown

In addition, due to the aging of the burner part and the control system of the incinerator, it often occurs that it is difficult to start the ignition, and sometimes it is difficult to start for 2 to 3 hours, and the incinerator often suddenly goes out for no reason during operation, which not only affects The quality of the product will cause a waste of energy
