Engineering Systems of Heat Supply and Working on Coal as Sources of Air Pollution by Finely Dispersed Dust

摘要

The article contains important issues about functioning of technical means and engineering systems of cities as sources of the human impact on the surrounding ecosystem, namely, the study of the functioning of boiler plants as sources of the human impact on a condition of the atmospheric air located near urbanized areas. So, we solved the problem of improving standardization systems, licensing, certification, environmental safety requirements, design and research activities in the building and operation of municipal services, in particular, improving methods of forecasting air pollution by solid particles contained in emissions released from the production of heat and electricity by burning coal. We made studies and mathematical treatment of the dispersed composition of dust emitted from the organized (boilers) and unorganized (ash dumps) boiler emissions sources, we established that solid particles are entered in the atmospheric air and most of them has a size up to 20 um. We got expressions for determining the sedimentation rate of fine particles of ash and slag.
