First question: What is artificial gas?
A: The gas produced by solid fuels such as coal, coke or liquid fuels such as heavy oil through dry distillation, vaporization or cracking is collectively referred to as artificial gas. According to the production method, it can generally be divided into dry distilled gas and vaporized gas (furnace gas, water gas, semi-water gas, etc.). The main components of artificial gas are combustible gases such as alkanes, olefins, aromatics, carbon monoxide and hydrogen, and contain a small amount of non-combustible gases such as carbon dioxide and nitrogen, with a calorific value of 16,000 to 24,000 kJ/m3.
Second question: What are the environmental requirements when using gas?
Answer: Gas equipment should be set up in the kitchen with fire resistance and fire resistance, the kitchen must not pile flammable and explosive materials, there must be no second fire source, and the ventilation of the gas environment should be ensured.
The third question: Why can't gas pipelines and facilities be sealed?
A: Gas pipes, valves, meters and other facilities require frequent inspection and regular maintenance. If these facilities are closed, it will bring inconvenience to inspection and maintenance, such as air leakage accidents can not be found in time, and gas in the closed environment is very prone to fire and explosion accidents.
Question 4: What are the regulations for the hose connecting the stove?
A: According to the relevant provisions of the "Gas Engineering Project Specification" GB 55009-2021: "When the household user pipeline or LPG cylinder regulator is connected with the burner, the special burner should be used to connect the hose." The service life of the hose should not be less than the scrap life of the burner. Burner connection hoses should not cross walls, doors, windows, ceilings and floors, should not be larger than 2.0m in length and should not have joints. ”
Fifth question: What should I pay attention to when using gas?
Answer: 1. When cooking and boiling water, the water in the pot and pot should not be filled to prevent the soup from boiling and overflowing and pouring out the flame, causing air leakage 2. When there is wind, the flame may be blown out by the wind, causing air leakage, and windproof measures should be taken; 3. Do not leave the person with gas to prevent a large amount of gas from spewing out due to the above two situations, which cannot be dealt with in time, causing accidents; 4. Educate children, do not play with gas switches at will, so as not to damage or forget to close the valve, causing accidents; 5. After three meals a day, the stove valve should be closed immediately, and the range hood should be smoked for 1-2 minutes. In the evening, before going out or after use, the stove switch and the valve behind the watch should be carefully checked to ensure that it is closed.
Sixth question: Why can't people live in a room where there is a gas pipe passing through?
Answer: The use of gas in the room set table, stove, gas pipeline in a room, once the gas leakage, carbon monoxide content is too high, inhalation of the body is easy to combine with the blood hemoglobin, so that hemoglobin can not transport oxygen and cause carbon monoxide poisoning (the so-called gas poisoning), in the event of Mars will also lead to explosion combustion, therefore, the kitchen and other rooms with gas facilities can not be used as a bedroom.
