Heat and Air Specifications
Each handling 15,000 SCFM. Recover heat from 30,000 SCFM of 1,500°F.
We manufactured the entire thermal fume incinerator using our in-shop, top-of-the-line equipment. The system consisted of CS hot air outlet plenum with internal insulation, stainless steel stacks and service platform, and stainless steel inlet ductwork. Some of the features of our system included four shell passes, vertical shell and tube heat exchangers (each handling 15,000 SCFM) installed in parallel, and hot heat exchangers with 309l S.S. tubes and tube sheets. In addition, both exchangers have intricate cold side faces and bypass dampers to recover heat from 30,000 SCFM of 1,500°F.
We provided more efficiency while simultaneously showcasing our proprietary free-floating air seal expansion system. This system is the best in the industry and lasts longer than other units, while still maintaining the integrity of the unit and the seal between air streams. For this project, the shell was all dye penetrated tested, and was built while using our standard Quality Control Sheets/system.
