Generally speaking, gas appliance refers to all appliances that use gas (artificial gas, liquefied petroleum gas and natural gas) as fuel in our daily life and industry, such as gas stoves, gas water heaters and wall-hung boilers.
Classification of gas burners
1. Gas water heater appliances: including water heaters, water heaters and gas boilers.
2. Gas cookers: including gas cookers, gas cookers (pots), gas cookers, gas insulation devices, etc.
Gas refrigeration appliances: including gas refrigerators and gas freezers.
4. Gas heating and refrigeration appliances: including gas heaters (heaters) and gas air conditioners.
5. Gas washing and drying equipment: including hot water washing machine, washing and drying machine, ironing equipment, etc.
With the acceleration of gas exploration, development and application in China, the application of gas appliance in China will bid farewell to the era of single product, and the industry in gas appliance will usher in unprecedented development.
Use of gas appliances
According to the national regulations, the service life of gas cookers and natural gas water heaters is 8 years, and they must be replaced upon expiration. When gas appliance is used beyond the limit, it is easy to cause problems such as flameout and safety device failure due to aging of internal components, resulting in gas leakage.
The installation of gas appliances shall conform to the Code for Design of Town Gas. The gas appliances installed by the gas professional company shall not be moved without permission, and must be moved by the gas professional company, which meets the requirements of the specification.
When using the gas stove, someone must be guarded to prevent the boiling soup from overflowing and extinguishing the flame or being blown out by the wind, resulting in air leakage and air leakage in the indoor space and fire and explosion accidents. After use, pay attention to close the oven door and valve in front of the furnace, so that people can go out and ensure safety.
The service life of gas appliance.
As early as a few years ago, the State Bureau of Quality and Technical Supervision issued the Safety Regulations for Household Gas Burning Appliances, which clearly stipulated that the service life of artificial gas water heaters, liquefied petroleum gas and natural gas water heaters and gas cookers in gas appliance was 6 years, 8 years and 8 years respectively. Therefore, the law requires manufacturers to ensure that the water heaters produced are relatively safe to use within six years, but after six years, their safety performance will become worse and worse due to normal wear and tear in the process of use.
According to relevant data, about 30% families have used gas water heaters for more than 6 years. Improper installation and operation will cause considerable losses, and most families lack professional maintenance awareness. The aging, performance degradation and safety protection device failure of the original water heater are enough to endanger the safe use of the water heater, which will lead to the decrease of water heater efficiency, carbon monoxide leakage, flameout in the middle or incomplete combustion. In particular, the in-line water heater installed in the early stage is more dangerous to use beyond the limit. At the same time, a large number of over-limit gas water heaters have caused energy waste and environmental pollution due to insufficient combustion.
If the gas water heater is not professionally maintained after one year, problems may occur in the second year, and accidents may occur at any time if it is used for more than five or six years without professional maintenance. Therefore, domestic gas water heaters should be professionally maintained at least once a year, and must be replaced in time after 5 to 6 years of use.
Consumers Association reminds consumers to do the following when buying and using gas water heaters:
1. Buy brand gas water heaters with good reputation and perfect after-sales service. Don't buy brand-name products without quality assurance, please ask qualified installers to install them. What brand of gas stove is good? Top ten brands of gas stoves >>
2. When using the gas water heater, don't close the doors and windows and keep proper ventilation; When the gas water heater is not in use, it is necessary to cut off the relevant gas source to prevent safety accidents;
3. Ask professional maintenance personnel to check and repair the "aging" gas water heater at home, eliminate safety faults and ensure the normal performance of the water heater;
4. Timely replace the "over-aged" gas water heaters that are still in use and the in-line gas water heaters that have been delisted.
