In the past few years, power generation sources mainly contributing to air pollution have been replaced by other, previously less important sources - transport, wood and coal open fire, and municipal waste combustion. The continuing town development, as well as the concomitant rise in the number of cars and fossil fuel or heating oil burning households, has become a dominant contributing source of total air pollution, especially over large urban agglomerations. Nowadays, emissions of gaseous pollutants from spark-ignition engines have been reduced markedly, owing to the wide spread use of three-way catalysts. A remedy has also been found for diesel engines. Technologies enabling manufacture of durable high-performance diesel particulate filters with self-regenerating are available and briefly presented. Little has been done so far to reduce emission from fuel burning in households. The reason is that the durability of the available catalysts appears to be insufficient. Nobel metals (Pt, Rh, Pd) which are successfully applied to the afterburning of exhaust gases from vehicles are useless. Some promising techniques such as catalytically aided heater, a heater providing complete combustion and catalytic heat generator with catalyst in the fluidized bed are discussed.
