Description

Technical Field

[0001] The utility model relates to a field, in particular to a liquid fuel combustion system with an oil tank over-temperature protection structure. Background Art

[0002] The current household combustion systems, such as stoves, water heaters, wall-mounted boilers, heaters and other equipment, usually use liquefied coal gas, natural gas or methanol. These fuels are all flammable and explosive dangerous chemicals. If they leak during use, they will cause carbon monoxide poisoning, and they will catch fire at the touch of an open flame, posing a serious threat to the safety of people's lives and property. New energy white oil and liquid wax are safe and not flammable and explosive. They have high calorific value and cannot be ignited by open flames. They are easy to transport and store and do not produce carbon monoxide. They have immeasurable benefits for the safety of people's lives and property. Therefore, the market has launched a combustion system that uses liquid fuels such as white oil and liquid wax as fuel. For example, the household new energy white oil and liquid wax stove proposed by patent number CN202221474453.4 uses a fuel nozzle and a blower to spray liquid white oil into the burner head for mixing and ignition.

[0003] However, the flame stability of liquid fuels such as white oil is based on the fact that white oil cannot be ignited at room temperature. If the temperature in the storage environment rises to a higher temperature, there is a safety hazard of premature ignition of the liquid before it is transported or sprayed for combustion. Therefore, further improvements are needed. Utility Model Content
