Question: What are the characteristics of liquefied gas combustion? Answer: Complete combustion of liquefied gas requires 30 times as much air; of course, the amount of oxygen needed for combustion varies slightly depending on the composition of the liquefied gas. While gas only requires 5 times as much air. Under standard conditions, 1 cubic meter of liquefied petroleum gas releases up to 2500 kilocalories upon complete combustion, which is more than six times that of coke oven gas. Due to its high calorific value, it also possesses great explosive power. Therefore, once a combustion explosion is caused by a liquefied gas leak, the danger is particularly great. http://bbs.hcbbs.com/static/image/hrline/4.gif Petrochemical Zone—New Ideas for Energy Saving: The “Creative Thinking” Campaign (Sponsors Wanted; highest returns ever) http://bbs.hcbbs.com/thread-1666758-1-1.html Sponsors are being sought for this campaign; those interested can contact the event organizer.

Its ignition temperature is lower than that of other fuels, typically ranging from 430 to 460°C. It has a narrow explosion limit of 1.5% to 9.5%, and its lower explosion threshold compared to other gases makes it highly dangerous; even a tiny spark can trigger combustion and explosion.

Complete combustion of liquefied gas requires 30 times as much air; of course, the oxygen demand for combustion varies slightly depending on the composition of the liquefied gas. While gas only requires 5 times as much air. Under standard conditions, the heat content per liter is as high as 2,500 kcal, which is more than 6 times that of coke oven gas; due to its high calorific value, it also possesses great explosive power. Therefore, once a combustion explosion is caused by a liquefied gas leak, the danger is particularly great.
It causes little pollution; it consists mainly of hydrocarbons made up of C3 (carbon triolefins) and C4 (carbon tetraolefins), which can be completely burned without producing any dust. It has a high calorific value; the calorific value per unit weight is twice that of coal, with a liquid calorific value of 45,185–45,980 kJ/kg.
Liquefied petroleum gas needs to be mixed with 20-30 times its volume of air when burning; if the air supply is inadequate, complete combustion cannot occur.
