An air pollution control system includes an emission treatment system configured to receive flue gas, to reduce at least one pollutant therefrom, and to output emission treated flue gas. A first air heater in fluid communication with the emission treatment system includes a heat exchanger for heating forced air introduced thereto above a base temperature and thereby cooling emission treated flue gas from the emission treatment system to a stack discharge temperature. A second air heater in fluid communication with the first air heater to receive heated forced air therefrom includes a heat exchanger for heating forced air introduced thereto to a preheat temperature for combustion in a boiler and thereby cooling flue gas introduced from a boiler to the second air heater to an emission treatment temperature. The second air heater is in fluid communication with the emission treatment system to introduce cooled flue gas thereto.

Integrated boiler and air pollution control systems

Regenerative selective catalytic reduction (RSCR) systems and processes are provided whereby NOand CO levels in gases are reduced by mixing the gas with a reactant and then introducing the gas into an RSCR apparatus for treatment that entails heating the gas, causing the gas to undergo one or more catalytic reactions, and then directing the gas through a heat transfer area, to which the gas provides heat for use in connection with successive cycles of the RSCR process.

In a catalytic recombiner system a stoichiometric mixture of oxygen and hydrogen are carried by a nitrogen stream through a catalytic converter. The stoichiometric mix is maintained by introducing oxygen into the stream under control of logic circuitry. The logic circuitry responds to the hydrogen level in an inlet stream and to oxygen levels before and after the catalytic converter.
