Natural Gas-fired Boilers vs Diesel for Boiler

August 13, 2020

Oil-fired boilers and gas-fired boilers are both products. They are classified according to the fuel used. The fuel of oil-fired boilers is fuel oil (such as diesel, engine oil, kerosene, etc.), and the fuel of gas-fired boilers is gas (such as natural gas, urban Gas, biogas and liquefied gas, etc.), depending on what fuel the boiler uses, the equipment is called the burner, the boiler with gas burner is called gas boiler, the boiler with oil burner is called oil boiler, the difference between oil boiler and gas boiler depends on what fuel the burner uses.

Both oil-fired boilers and gas-fired boilers can be divided into steam boilers, hot water boilers and heat-conducting oil boilers, but the fuels used are different. At present, oil-fired boilers, gas-fired boilers and hot water boilers use the most fuel on the market. In addition, because the oil-fired boilers and gas-fired boilers use the same boiler host and lower operating costs, users usually compare oil-fired boilers and gas-fired boilers to understand the advantages and disadvantages of the two.

Thermal efficiency >98% >80% >98%


Oil-fired boilers are widely used, and their structural performance is roughly the same as that of natural gas boilers, that is, both gas and oil can be used. The cost of using fuel oil is twice that of natural gas boilers.
Gas boiler: High efficiency, cleanliness and environmental protection are the greater advantages of gas boilers. Because natural gas burns without impurities, it does not damage the boiler and related accessories, and the boiler has a long life, which is specified as 15 years, but it can basically be used for a long time.
