Which is better for environmental protection comparison between oil-fired boilers and gas-fired boilers?

There is not much difference between oil-fired boiler and gas-fired boiler in terms of body structure, but the heating surface is adjusted accordingly because of the different calorific value of fuel. So what's the difference between oil-fired boilers and gas-fired boilers in terms of environmental protection? Here we will take you to compare the environmental protection of oil-fired boilers and gas-fired boilers.

Comparison of environmental protection between oil-fired boiler and gas-fired boiler

1. Emissions

At present, the national emission standards for oil-fired boilers in key areas are 30 mg/nm for particulate matter, 100 mg/nm for sulfur dioxide, 200 mg/nm for nitrogen oxides, and 1 or less for smoke blackness, while those for gas-fired boilers are 20 mg/nm for particulate matter, 50 mg/nm for sulfur dioxide, 150 mg/nm for nitrogen oxides, and 1 or less for smoke blackness. In addition, more stringent standards are set by local governments. It can be seen that compared with the environmental protection of oil-fired boilers and gas-fired boilers, gas-fired boilers have cleaner emissions and higher environmental protection standards. 

2. Operating cost

The cost of fuel oil is high, which is about 1-2 times that of gas-fired boilers. Moreover, the thermal efficiency of oil-fired boiler is 95%, which is obviously lower than that of gas-fired boiler, and the thermal efficiency of condensing gas-fired boiler has even exceeded 100%. 

To sum up, the environmental comparison between oil-fired boilers and gas-fired boilers is clear at a glance, but on the premise of meeting the environmental impact assessment, gas-fired boilers and oil-fired boilers have their own advantages and disadvantages. When purchasing boiler products, we should choose a boiler product that is more suitable for enterprises.

Since the establishment of ZOZEN Boiler for more than 30 years, it has developed into a modern manufacturing enterprise integrating boiler complete equipment system design, product manufacturing, marketing, installation and debugging, operation service and maintenance and technical transformation. The company's products cover oil-fired and gas-fired boilers, biomass boilers, coal-fired boilers, circulating fluidized bed boilers and heat-conducting oil boilers, etc. The suitable boilers and heating systems can be selected according to the actual working conditions of users, without worrying about the environmental comparison between oil-fired boilers and gas-fired boilers.
