A particle removal system provides for the removal of submicron particles in gas streams, such as combustion flue gases or diesel exhausts. The gas stream is treated to permit very fine particles to coagulate through a short residence time in the conduits handling the gas stream, and thereafter is conditioned to establish saturation of the gas stream at a low temperature, such as by water injection. The saturated stream of gas containing the particles is then passed through a particle growth chamber or section where steam is injected into the gas to establish a supersaturation condition, causing the particles in the gas stream to grow in size by water condensing around the particles. The particles are grown to a size that is near one micron, and are removed through conventional particulate removal devices.
