Mixed-oxygen preheating oil burning system

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...

Problems solved by technology

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 is not easy to control, and the operation is difficult

2. Because the preheating temperature of the fuel is not enough, the gasification effect is not good, so the fuel cannot be fully burned, and the problem of black smoke cannot be solved.

3. Since the fuel remaining around the fuel injection nozzle cannot be removed in time, it is easy to generate carbon deposits, block the fuel nozzle and fail to work normally, and because the nozzle of the fuel nozzle is set on the nozzle head, it is not easy to repair after clogging

In the mixed oxygen preheating fuel combustion system, the pipelines that the control valve needs to control include the main fuel pipeline, the preheating fuel pipeline and the compressed air pipeline, etc. If the existing shut-off valve is used, there are the following problems: 1. The pipeline control function of the valve is simple, it only has a switch and a simple adjustment function, and it is not easy to adjust and control the ratio of preheated fuel oil and compressed air

2. The stop valve takes up a lot of space, and there are many pipelines in the combustion system that need to be controlled, so the entire valve body takes up more space

3. The operation of the cut-off valve switching from the preheating fuel stage to the main fuel combustion stage is cumbersome

4. Fuel and compressed air need to be controlled in conjunction to achieve the ideal combustion effect, which is difficult to control
