Configuration 1.4 is a T.O. fitted <strong>with</strong> a gas-to-gas exchanger and a heat recovery boiler. The heat<br />
exchanger heats incoming combustion air or waste gases, and the boiler further extracts the heat<br />
available in the flue gas discharged from the exchanger. This configuration offers flexibility in the<br />
amount of steam produced versus fuel usage.<br />

Configuration 1.5 illustrates a Catalytic Oxidizer fitted <strong>with</strong> a gas-to-gas exchanger. The<br />
heat exchanger preheats contaminated air which is routed to chamber containing catalyst<br />
material. The catalyst causes oxidation of the HC to occur at much lower temperatures than<br />
in a thermal oxidizer, thus greatly reducing the fuel usage. The HC content of the air is<br />
generally limited to less the 0.75 % because of temperature limits of the catalyst.<br />
