What are the differences between gas-fired boiler and oil-fired boiler?

11 Sep 2020

With the continuous development of boiler manufacturing process and technology, fuel types of boiler have also increased, such as various combustible gases, fuel oil, biomass, coal and so on.

The differences between gas-fired boiler and oil-fired boiler:

1) Combustion method. Gas-fired boiler: a mixture of fuel gas and air burns in a suspended state in the furnace; oil-fired boiler: a strong mixture of fuel oil atomized by oil burner and air burns in a suspended state in the furnace. The same point is the required mix with air. Some oil-fired boilers burn heavy oil, which has a high viscosity and must be preheated before it can be piped and used.

2) Burner. Gas-fired boiler uses gas burner while oil-fired boiler uses oil burner.

3) Operating costs. The costs of oil-fired boiler is higher than that of gas-fired boiler due to the costs of various kinds of fuel oil.
