A heat recovery and pollution abatement process with stackless operation for removing the products of combustion from hot boiler flue gas (45) comprising the steps of passing said hot boiler flue gas through a cloud of steam or mist (46), cooling the hot moist flue gas and recovering the heat therefrom (47), passing the partly cooled hot moist flue gas through a second cloud of mist comprised of cold water to total saturation (48), collecting the resulting stream of acid water, forcing the treated flue gas, mixing the treated flue gas with outside air, directing the forced treated air to atmosphere, shutting off the process in the absence of boiler flue gas.

1. A process for removing contaminants from flue gas, process gas or air by flowing the flue gas, process gas or air through a first misting array, a first condensing coil, a second misting array, a second condensing coil, and a fan chamber, the process comprising: flowing the flue gas, process gas
1. A process for removing contaminants from flue gas, process gas or air by flowing the flue gas, process gas or air through a first misting array, a first condensing coil, a second misting array, a second condensing coil, and a fan chamber, the process comprising: flowing the flue gas, process gas or air in a first direction, directing a first cloud of steam or mist of the first misting array comprised of droplets 5 to 10 microns in diameter in a second direction, substantially opposite to the first direction, against the flow of flue gas, process gas or air causing a pressure differential between the steam or mist and the flue gas, process gas or air, controlling a relative humidity of the first misting array to increase a relative humidity of the flue gas, process gas or air in the first misting array to 90 to 95% relative humidity but below saturation, flowing the flue gas, process gas or air having increased relative humidity through the first condensing coil, recovering heat from the first condensing coil, directing a second cloud of mist, formed of water only, at the flue gas, process gas or air from the second misting array, in a direction countercurrent to the direction of flow of the flue gas, process gas or air totally saturating the flue gas, process gas or air.
