Waste heat recovery technologies and applications

The main waste heat recovery methods used for this process include semi wet and wet open combustion and supressed combustion techniques. The open combustion system includes the use of a waste heat boiler to recover waste heat that is produced as a result of the reaction of oxygen in the furnace gas duct.

Waste Heat Boiler - Process Combustion Corporation

The boiler feed water economizer is basically a gas-liquid heat exchanger located after the boiler evaporator section. The economizer also uses a portion of the energy contained in the thermal oxidizer combustion gases (after the waste heat boiler) to preheat the boiler feed water before it enters the boiler evaporator section.

Boiler technologies from B&W Vølund

The convection pass of a boiler is characterized by the mode of energy transfer from the hot flue gas to water or steam, which is primarily via convective heat transfer. On waste-to-energy boilers the flue gas temperature (at the entrance to the convection pass) is typically below 625 °C, which makes it possible to put heating surfaces inside
