Title: Process and system for quenching heat, scrubbing, cleaning and neutralizing acidic media present in the flue gas from the firing of fossil fuel

Abstract: The present invention provides a novel process for quenching heat, scrubbing, cleaning and neutralizing the hot and dirty fossil fuel fired flue gas liberated by a fossil fuel fired boiler using the high temperature and high pressure present in fossil fuel fired boiler blow-down comprising the steps of quenching the fossil fuel fired flue gas by evaporating sufficient quantity of water from sea water/scrubbing liquid and mixing vapors thus generated with hot and dirty flue gas; using the high temperature and high pressure present in fossil fuel fired boiler blow-down (waste water) for atomizing/spraying high alkalinity sea water/scrubbing liquid on said flue gas to neutralize the acidic substances in said flue gas.
