Embodiment 1

[0025] The vaporized petroleum gas blast burner of the present embodiment has a structure such as figure 1 Shown, comprise air duct 9, the inlet of air duct 9 is connected with the compression fan 11 that is connected with damper 10, and the outlet is connected with air-wind mixing pipe 2, and the end of air-air mixing pipe 2 is provided with flame outlet 1, and air duct 9 The upper end of the outlet is provided with a fire viewing hole 5, and the lower end is provided with an ignition port 6. An air disc 4 is embedded at the junction of the outlet of the air duct 9 and the air-wind mixing pipe 2. The middle part of the air disc 4 is equipped with a nozzle 3, and the nozzle 3 passes through the conduit and The air supply pipe 13 connected with the air supply valve 12 is connected. Among them, the conduit is composed of a thin conduit 7 (copper pipe) arranged inside the air duct 9 and connected to the nozzle 3, and a thick conduit 8 arranged outside the air duct 9 and connected...

Embodiment 2

[0029] The vaporized petroleum gas blast burner of the present embodiment has a structure such as figure 2Shown, comprise air duct 9, the inlet of air duct 9 is connected with the compression fan 11 that is connected with damper 10, and the outlet is connected with air-wind mixing pipe 2, and the end of air-air mixing pipe 2 is provided with flame outlet 1, and air duct 9 The upper end of the outlet is provided with a fire viewing hole 5, and the lower end is provided with an ignition port 6. An air disc 4 is embedded at the junction of the outlet of the air duct 9 and the air-wind mixing pipe 2. The middle part of the air disc 4 is equipped with a nozzle 3, and the nozzle 3 passes through the conduit and The air supply pipe 13 connected with the air supply valve 12 is connected. Among them, the conduit is a spiral pipe 14 spirally wound inside the air duct, with the same pipe diameter, the expansion distance between two adjacent spiral pipes and the distance between the spir...

Embodiment 3

[0032] The difference between this embodiment and the second embodiment is that the conduit is composed of a thin conduit arranged inside the air duct 9 and connected to the nozzle 3 and a thick conduit arranged outside the air duct 9 and connected to the air supply pipe 13, wherein the thin conduit It is a helical duct 14 spirally coiled inside the air duct 9, the expansion distance between two adjacent helical ducts and the distance between the helical duct and the duct wall are 5-10mm, and there is a slope of 180° between the helical duct 14 and the thick duct. The inner diameter of the thick conduit is 37.5 mm, the inner diameter of the spiral pipe 14 is 4 mm, and the combustion efficiency can reach 31.4%. The results are shown in Table 1. There is an angle of 40° between the rotating wind ejected from the rotating wind disk and the nozzle, so as to form a negative pressure and form a negative pressure zone in front of the nozzle. The taper of the air-wind mixing pipe 2 is...

Abstract

The invention relates to a vaporized petroleum gas blast combustor which comprises an air pipe. An entrance of the air pipe is connected with a compression fan which is connected with an air door, and an exit is connected with a gas and wind mixing pipe. The end portion of the gas and wind mixing pipe is provided with a fire ejecting opening. The upper end of the exit of the air pipe is provided with a fire observing hole, and the lower end of the exit of the air pipe is provided with an ignition opening. An air plate is embedded into the joint of the exit of the air pipe and the gas and wind mixing pipe, a nozzle is arranged in the middle of the air plate, and the nozzle is connected with a gas supply pipe through a guide pipe, wherein the gas supply pipe is connected with a gas supply valve. The vaporized petroleum gas blast combustor has the advantages that gas ejecting pressure is increased, combustion is more sufficient and more fast, and the combustion efficiency is improved; multiple measures are taken to prevent condensed fluid in the guide pipe from generating so as to prevent erosion on pipelines and waste of resources; an electric heating base is used for direct heating, the equipment structure is simple, and standardized production and installation are achieved; the vaporized petroleum gas blast combustor can be suitable for various combustible gas combustion apparatus and installation and operation are convenient to carry out; temperature can be adjusted and controlled, and the energy-saving effect is good.

Description

technical field [0001] The invention relates to a gas combustion device, in particular to a blast burner for vaporized petroleum gas. Background technique [0002] At present, energy-saving and environmentally friendly fuels are the goals pursued by human society. Liquefied petroleum gas is a kind of energy with high thermal efficiency, convenient use and abundant resources. It has been widely used in industrial production and civil life. On larger occasions, the vaporized petroleum industry is stored in the reserve tank. When in use, the vaporization equipment will gasify the petroleum liquid, and the vaporized petroleum gas will be transported to the burner of the kiln through the pipeline for combustion. At present, the burners used in kilns on the market are generally air-conditioning equipment, which can only burn normal temperature gas, and are not suitable for high-temperature and high-pressure vaporized petroleum gas combustion. Control, it is easy to cause fire, br...
