About RTOs (Regenerative Thermal Oxidizers)
Summary:
An RTO burns very lean waste gases without using much fuel. Operating temperature isabout the same as a normal thermal oxidizer (say 1600oF), but the hot flue gas passesthrough a heat exchange module before reaching the stack.
At least 2 of these modules are used – one is always absorbing heat from the flue gas andone is always shedding heat into the waste gas. The modules are insulated boxes full ofheat exchange media – usually ceramic packing. When a box has absorbed all the heat itcan, it is taken offline and waste gas is sent through it backwards until it is cool again.
Once cooled, it is taken offline and hot flue gas is again sent through it. Two boxes are needed so the flue gas always has a path to the exhaust stack – each box switches from heating to cooling every 5 minutes, or so. Specialized “airflow switching valves”, set on a timer, are used to make the flow changes.
