Liquefied gas is a multi-component mixture, mainly composed of heavy hydrocarbons containing 3 or 4 carbon atoms (C3, C4). Its main components are propane, propylene and butyl alkyl. Its main ones are butene, pentane, etc. The higher the number of carbon atoms, the higher the boiling point. The higher the boiling point, the harder it is to gasify. During use, the c3.c4 that is most easily vaporized gradually decreases. The remaining residual liquid in the cylinder is not easily vaporized. A small amount of C4.C5 accounts for 10-20 of the heavier part of the mixture.
The main components of liquefied gas are propane, propylene, butane, butene and butadiene. The residual liquid is a mixture of pentane and hexane (which is a high calorific value fuel and the main component of making gasoline). The molecular formula of propane is C3H8, the molecular formula of butane is C4H10, the molecular formula of pentane is C5H12, and the molecular formula of hexane is C6H14. The combustion value of propane is 529.20 kilocalories/g, the combustion value of butane is 687.20 kilocalories/g, the combustion value of pentane is 847.10 kilocalories/g, and the combustion value of hexane is 999.20 kilocalories/g. Gasification temperature: propane lt; -38.3°C; butane lt; 2.2°C, pentane.gt; 37°C hexane: 67°C; the remaining liquid depends on the purity of propane and butane, its composition and the external temperature. The destination of these residual liquids: 1) Heating, scalding with hot water, and roasting with fire. The temperature of the upper part exceeding C5 reaches above 67°C. It will naturally vaporize to the saturation level and participate in combustion. 2) Put the cylinder upside down or stand upside down. 3) Entrust someone or pour out the residual liquid yourself. 4) Recycling of gas stations. I heard that the residual liquid is recycled, but it was actually found that most of it was dumped. Liquefied gas means that the gas purchased by the user cannot be burned completely. The residual liquid of high calorific value fuel that remains in the cylinder after refilling is caused by the composition of the gas supplied by the gas supply unit and the purity of propylene butane. The residual liquid should be disposed of by the gas supply unit. exchange.
The burner is specially designed to burn out the residual liquid in the cylinder that cannot be burned any more. Its technical feature is to use the principle of liquid kinematics and the charging pressure of the filling gas. The vapor pressure of alkane, the positive and negative pressure difference of the tube, promotes the heat generated by the random collision motion of the residual liquid molecules during use, and is redistributed among all degrees of freedom and mixed with other saturated gases by adjusting the liquid-gas ratio. Participating in combustion solves the problems of previous equipment. No need to add any kinetic energy, heat energy or add any additives. Without changing any structure or usage of the cylinder or stove, the remaining liquid in the cylinder can be burned out, significantly increasing the calorific value and extending the burning time of the cylinder.
With the advent of the burner, the residual liquid left after burning liquefied petroleum gas will become a thing of the past. It uses the principle of liquid kinematics to burn the residual liquid when the cylinder is in normal use. It is advanced among the burners in the country. For a long period of time, it can save money for users and save energy for mankind. In the era of promoting energy conservation and emission reduction, it is worthy of comprehensive promotion and application.
The burner has been researched and developed for more than ten years. The fruit of the hard work of two generations has gone through thousands of trial productions in the catering industry, machining, and successful large-scale cutting trial production. It has been inspected by Gaizhou Municipal Quality Supervision Bureau and Municipal Pressure Vessel Unit. Conclusion; "Safe and reliable". Liquefied gas is a flammable and explosive gas. It is recommended that relevant national departments pay attention to the promotion of unified installation and application.
