Technology overview

"Regenerative Catalytic Thermal Oxidation is a combination of merits with Regenerative thermal oxidation and Catalytic thermal oxidation. In case of 2-Chamber regenerative type, the fuel consumption is minimized through realization of catalytic combustion while maintaining low temperature between 300~450℃ degrees at combustion chamber with over 95% of heat recovery ratio."

 

Technology fundamentals

"Regenerative catalytic thermal oxidizer is based on the fundamentals of regenerative thermal oxidizer with catalytic combustion function added as a means of reducing the cost of fuel required in maintaining the temperature of combustion chamber between 750-900℃. The representative catalysts are either Platinum (Pt) or Palladium (Pd) depending on the component or concentrition of gas. Particularly, in the event of substance inflow that may result in catalyst poison such as lead, heavy metal, ammonium hydrogen, or phosphorus, it requires special attention in selecting the catalyst type and planning a separate pre-treatment device. The catalyst is to be installed in upper part of regeneration chamber where the VOC gas is oxidized by catalytic reaction during gas discharge."

 

Process

Regenerative catalytic thermal oxidizer has basically identical processing as regenerative thermal oxidizer.

 

"It features a simple and compact combustion device structure. The gas flow is simple and subsequently generates less differential pressure. Heat media is constructed with ceramic materials of HoneyComb type in order to maximize the regeneration effect with minimized device size. The damper that converts gas flow is made for prompt switching and maintenance, and also for the high heat recovery efficiency by converting on a proper cycle. Temperature in combustion chamber is standardized at default value to provide and maintain appropriate amount of fuel automatically. "

 

Device description


"With Our 2-Chamber RCO, A and D dampers are opened with B, C still closed where the gas inflow from A is discharged through D after processing. Few minutes after this, A and D are closed while B and C are opened by the damper switch where the gas inflow from C is discharge through B after processing. This operation of damper induces repetitive regenerations and discharges to finally generate heat exchange. Rotary 1-Can RCO also operates with identical process."
