Before liberation, the development of gas industry in China was very slow. By 1949, only nine cities in China have gas facilities, and the equipment is generally outdated and the technology is backward. The population using natural gas is only 270,000. After liberation, with the continuous development of metallurgy and petroleum industry, China's gas industry has also developed rapidly.

Since 1965, liquefied petroleum gas has been widely used in China. The reform and opening up for more than 20 years is a period of great development of urban gas in China. With the adjustment of national economic policies, the state attaches great importance to energy and environmental protection, decides to include the development of gas industry as one of the major technical policies, and proposes that cities should be gradually gasified, which provides positive support for the development of gas industry.

Precautions:

1, the fuel tank should be flat. The gas tank itself is a metal product. On the one hand, the tank wall is hard and not easy to be damaged. On the other hand, once the bulkhead is damaged, we can't take effective measures in time, don't know how to deal with it correctly, or even be at a loss. For the sake of safety, it is the most suitable method to put the gas tank upside down on the flattest floor of the kitchen.

2, always pay attention to whether the gas leaks. There are countless accidents caused by gas, and most of the safety hazards caused by gas come from gas leakage. Brush with soapy water to check whether the gas leaks. It is forbidden to check with naked flame.

3. If leakage is found, first open the doors and windows to let the air circulate, put out the fire source, and then contact the gas company to ask professionals to come and deal with it.
