Who has the energy saving retrofit program for gas boilers?

Burner Retrofit: If it is an oil boiler, you can consider retrofitting it to a gas one, or an oil-gas dual-fuel one, which can save energy consumption and will have a 3-5% energy efficiency improvement.

The burner with oxygen regulation can improve the thermal efficiency of the boiler by more than 1%

Adopting the mature combustion management system and combustion control device, change the mechanical proportional gas ratio control to electronic gas ratio control, which can improve the energy efficiency by 2-3%.

The actuator is controlled by high-efficiency frequency converter, which saves power by about 30% and further improves energy efficiency

Installation of flue gas recycling device, utilizing boiler exhaust preheating and lowering the temperature of exhaust flue gas, the energy saving rate can be up to 4-5%
