Oxidizers Recover Energy
In ambient temperature applications, there is not a lot of heat left over in the regenerative thermal oxidizer's stack to allow for efficient secondary heating. According to CPI, it has developed a system that can affect the oxidizer’s thermal efficiency, raising the stack temperature to provide efficient heating. In certain applications, says the company, energy derived from VOCs is sufficient to offset the lower efficiency, and the net result is savings that otherwise might have been lost up the stack. The most common form of energy recovery is hot air delivered back to the process. Other options include heating, makeup air, hot water or other heating fluids.
