What fuels can be used in gas boilers?
Gas-fired boilers use gaseous flammable gases (including liquefied combustible gases) as fuel. These gaseous fuels have relatively higher calorific value and less pollutant emissions, and are gradually becoming popular among corporate users.
Some common gas-fired boilers and gas fuels are mainly these types. The small-scale boilers are simple to introduce to you, and compare the cost-effectiveness of each fuel.
1.LPG (Liquefied Petroleum Gas): LPG
Main ingredients: propane, other ingredients: butane, ethane, etc.
The calorific value is approximately 46,000 KJ/kg.
2.LNG (Liquefied Natural Gas): natural gas
Main components: methane, a small amount of ethane and other gases
The calorific value is approximately 8,600 Kcal/Nm3.
3.Gas
Gas hungry components are more complex, with a calorific value of about 3,000-4,000 Kcal/Nm3.
4.Air mixing (LPG-AIR)
A mixture of liquefied gas and air with a calorific value of approximately 9,000-10,000 Kcal/Nm3.
Comparison of calorific value: liquefied petroleum gas > air-mixed gas > natural gas > gas
Economic level: gas > natural gas > air admixture > liquefied petroleum gas.
Gas boilers are designed to burn gaseous fuels, typically natural gas or propane. However, some gas boilers can also be adapted to burn other gaseous fuels, such as biogas or syngas. The specific fuel that a gas boiler can burn depends on the design of the boiler and the availability of the fuel in the local area.
It is important to note that gas boilers are not designed to burn solid or liquid fuels, such as coal, wood, or oil. Attempting to burn these fuels in a gas boiler can lead to inefficient combustion, increased emissions, and potentially dangerous conditions. Solid and liquid fuels require specialized boilers that are designed to handle the unique combustion characteristics of these fuels.

On March 20, 2025, the Guizhou Jinyuan Zhijin “Replacing Small Units with Large Ones” Relocation Project (2×660 MW), under State Power Investment Corporation, successfully achieved the first ignition of its boiler. This project replaced traditional oil-fired ignition fuel with liquefied natural gas (LNG), setting a new precedent for employing clean energy in 660 MW ultra-supercritical “W” flame boilers. As a key equipment supplier for this project, ZOZEN Boiler prov...15 Jul 2025
