Flameless regenerative thermal oxidizer

Abstract

The present invention relates to a flameless thermal storage combustion system, and more specifically, to a flameless thermal storage combustion system in which auxiliary fuel is introduced along with the incoming gas into the thermal storage combustion system to maintain the concentration of the gas entering the combustion system at a high concentration, thereby maintaining a constant temperature within the combustion system without heating by a burner, which enables automatic operation of the combustion system and allows for safe operation using a bypass pipe. According to the flameless thermal storage combustion system formed as a preferred embodiment of the present invention, the combustion chamber burner is operated only during the initial stage, thereby minimizing the generation of NOx; fuel consumption occurs because auxiliary fuel is injected only at low concentrations; efficient operation is possible because the combustion chamber temperature can be maintained by appropriately injecting auxiliary fuel through a mixer even at extremely low concentrations and high air volumes; and effects such as safe operation are achieved by connecting the bypass pipe to a chimney to prevent excessive pressure increase or overheating inside the combustion chamber.
