One cubic meter of natural gas can be used for about one and a half hours. If it is used for home cooking, it needs about 0.5-0.7 cubic meters of natural gas per hour. If a gas-fired water heater is used, it needs 1.0- 1.3 cubic meters of natural gas per hour. Natural gas is mainly used as fuel, which can make chemicals and liquefied petroleum gas, and is the main raw material of modern industry.
