Apparatus and a process are described, wherein furnace flue gas, containing moisture, is expanded through a pressure drop sufficient to cause saturation of the gas. The resulting condensation of water increases the mass of particles, making them easier to separate from the gas. Acid components of the flue gas may be similarly rendered more easily separable. These wetted particles are then separated and removed from the flue gas. The cleaned flue gas is then compressed back up to chimney pressure for discharge. A flue gas cleaner of this invention thus renders particle forming fuels, such as low cost coal, more readily useable, while meeting appropriate particle emissions requirements.
