Abstract

The invention relates to a mixed-oxygen preheating oil burning system. The system comprises an oil storage tank, a control valve, a combustion apparatus and corresponding connecting pipelines. The oil storage tank comprises a tank body. The top of the tank body is provided with an oil filling opening, a gas filling opening and an oil-gas switch. The inner end of the oil-gas switch is connected with an oil suction pipe extending to the bottom of the tank body and a gas transfer pipe at the upper part in the tank body. The outer end of the oil-gas tank is connected with an oil transfer pipeline and a gas transfer pipeline. The control valve comprises a valve body provided with a switch valve, an electromagnetic valve, an adjusting valve and a pressure maintaining valve thereon. The combustion apparatus comprises a grate, a heat-insulation cylinder, a preheating pipe, a fire cylinder, a fire distributing cylinder, a main oil burner, a preheating oil burner and a compressed air burner. The invention has the advantages of high preheating temperature, adequate combustion and safety. The invention can be widely used in the occasions needing oil burning stoves.

Description

technical field

[0001] The invention relates to a combustion system, in particular to an oxygen-mixed preheating fuel combustion system. Background technique

[0002] The existing preheating combustion device generally uses compressed air to pressurize the fuel tank, forcing an appropriate amount of fuel (fuel) to be sprayed onto the high-temperature combustion cotton, and then artificially ignites the high-temperature cotton soaked in fuel, so that the fuel is naturally burned and heated for preheating When the fuel is heated to a certain temperature, the oil circuit switch is turned on for normal combustion. There are some problems in this preheating fuel combustion system: 1. Since the fuel is directly injected on the high-temperature cotton for natural combustion, the fuel cannot be fully atomized and the ignition point is low, so it is difficult to achieve and maintain high-temperature preheating of the fuel preheating pipe At the same time, the fuel injection volume i...

Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] Such as figure 1 , figure 2 As shown, the present invention includes an oil storage tank 1, a control valve 2, a compressed air source 3, a combustion device 7 including a main combustion nozzle 4, a preheating combustion nozzle 5, and a compressed air nozzle 6, an oil delivery pipeline 8, a gas delivery pipeline 9, etc. Connect the tubing.

[0027]The oil storage tank 1 of the present invention includes a tank body 11, the top of the tank body 11 is provided with an oil filling port 12 that can replenish fuel into the tank body 11, and an inflator or a compressed air source 3 can be used to fill the tank body 1 with compressed air. The gas injection port 13 and an oil-gas switch 14. The oil-gas switch 14 inner end is connected with an oil suction pipe 15 extending into the bottom of the tank body 11 and a gas pipeline 16 positioned at the ...
