Both liquefied gas boilers and natural gas boilers belong to the category of gas boilers. Liquefied gas boilers and natural gas boilers are actually not much different in terms of the structure of the boiler, but the choice of burner is different from the calorific value of the fuel.

　　1. Comparing fuels between liquefied gas boilers and natural gas boilers

　　Liquefied petroleum gas is a light component gas in the petroleum refining process, the main components are propane and butane. The calorific value of liquefied gas is 10200 kcal per cubic meter.

　　Natural gas is mined underground and its main component is methane. The calorific value of natural gas is 8,500 kcal per cubic meter. However, natural gas is one of the safer fuels. It does not contain carbon monoxide and is lighter than air. Once it leaks, it will spread upward immediately, and it is not easy to accumulate to form explosive gas, and it is safer.

　　2. The burners of liquefied gas boilers and natural gas boilers are different

　　Because the calorific value of liquefied gas and natural gas is different, in order to ensure the rated calorific value, the burner nozzle of the boiler is different. The burner nozzle of the liquefied gas boiler is larger, and the air input is also adjusted to ensure the efficiency of the boiler.

　　3. The fuel costs of liquefied gas boilers and natural gas boilers are different

　　The calorific value of liquefied gas and natural gas are different, and the energy released by combustion is different. In order to achieve the same effect, more natural gas is needed. The specific cost difference needs to be determined according to the price difference between the user's local liquefied gas and natural gas.
