Abstract

Energy economy in Latvia has a hard time now. Therefore, Investigation of possibilities of en energy efficiency improvement in industrial plants and district heating systems has acquire vital imortance and any energy saving is closely associated with environmental protection. The results of a pasive experiment investigating nitrogen oxide, carbon monooxide and suophur dioxide in exhaust gases from boilers and economy=rs are provided for an analyses of coal combution process efficiency in fixed grate furnace of small district heating boilers (heat load less than 1.0 MW). It allows one to find the possibilities for energy saving and air pollution reduction.

Similar experimental results are obtained investigating steam biolers units (steam generation capacity up to 20 tons per hour). In this case, a combustion process of natural gas is different from periodical coal combustion process and changes of emission amounts are smooth.
