Direct-fired recuperative thermal oxidizer fromGlenro Inc.cleans manufacturing exhaust streams that contain organic hydrocarbon contaminants. The oxidizer processes 21,000 scfm of exhaust and uses primary and secondary heat recovery subsystems to recapture heat energy for reuse. Primary recovery subsystem preheats the inlet air stream before it goes to the combustion chamber. The secondary heat recovery system mixes a controlled portion of the clean, hot, oxidized exhaust air with room air to supply energy to a process oven. The remaining exhaust air is used to fire a waste heat boiler that produces steam, which then can be used to satisfy space or process heating needs.
