1) environmental protection
V liquefied petroleum gas (LPG) has anesthetic effect and can cause dizziness, headache, vomiting and even death. Pollution of water, soil and atmosphere.
V natural gas produces very few substances that can affect the health of human respiratory system in the process of burning. The carbon dioxide produced is only about 40% of that of coal, resulting in a low greenhouse effect, which can fundamentally improve the environmental quality, and no waste residue or waste water is generated after burning.
2). Economic benefits
Comparison of natural gas, liquefied petroleum gas and electricity
V generates the same heat (8,600 calories), and the costs are:
Natural gas: 2.40 yuan; Liquefied gas: 5.95 yuan; Power: 5.7 yuan
Ratio: 1:2.5:2.4
V thus it can be seen that among the three common energy sources, natural gas is the cheapest, electricity is the second, and liquefied gas is the most expensive.
The products of v natural gas combustion are CO2 and H2O, which will not corrode the cooker and can extend the service life of the cooker and greatly reduce the maintenance cost of the users.
3) safe and reliable
In case the pipe leak or the valve is not closed, LPG diffuses indoors and accumulates from the bottom to the top. When the content reaches the explosion limit (1.7% to 10%), it will explode when encountering Mars or electric spark. So when using must prevent leak, cannot paralyze careless, lest cause harm. At the same time, the long-term storage of liquefied gas tank in the indoor invisible increases the risk of users.
V natural gas is one of the safer gases. The explosion range is 5%-15%. It is lighter than air.
V natural gas is transported through pipelines to increase the convenience of use, and it is fully attended by professionals and has more security means, which greatly reduces the safety risk of users.
