Hot flue gas from the furnace is routed through the heat exchanger (HEX) and cooled in a controlled way. Through this controlled flue gas cooling, dioxin formations are eliminated. Energy is transferred from flue gas to water. The recovered flue gas water is routed to existing boiler feedwater preheater or district heating applications.

Both gas and oil fired boilers use controlled combustion of the fuel to heat water. The key boiler components involved in this process are the burner, combustion chamber, heat exchanger, and controls. The burner mixes the fuel and oxygen together and, with the assistance of an ignition device, provides a platform for combustion.
