Application of Flue Gas Waste Heat Recovery Technology in Gas Boilers

Flue gas waste heat recovery technology in gas boilers is very common, it can significantly improve the energy efficiency of gas boilers and reduce energy waste. The following are some of the common applications of flue gas waste heat recovery technology in gas boilers:

Flue gas heat exchanger (flue gas heat exchanger): The combustion process in a gas boiler produces a large amount of flue gas, which contains a large amount of heat energy. By installing a flue gas heat exchanger at the flue gas discharge, the heat from the flue gas can be transferred to the boiler feed water and used to heat the feed water. This reduces the temperature of the feed water and reduces the amount of fuel burned, thus improving the thermal efficiency of the entire system.

Flue gas condensation recovery technology: The flue gas produced by gas boiler combustion contains a large amount of water vapour. By installing a flue gas condensation recycler at the flue gas discharge of the gas boiler, the water vapour in the flue gas can be condensed into liquid water and the released condensation heat energy can be recovered. This technology can significantly improve the thermal efficiency of gas boilers, often by more than 90 per cent.

Flue gas waste heat utilisation: In addition to the direct recovery of heat energy from the flue gas, flue gas waste heat can be used for other purposes such as heating, hot water supply or other thermal energy requirements. Through the flue gas waste heat recovery system, the heat energy in the flue gas can be transferred to other media that need to be heated, thus reducing the need for other energy sources.

The application of flue gas waste heat recovery technology can significantly improve the energy efficiency of gas boilers and reduce the consumption of fossil fuels. This not only helps to save energy and reduce energy costs, but also helps to reduce greenhouse gas emissions and environmental pollution. Therefore, flue gas waste heat recovery technology is widely used in modern gas boiler systems.
