Ensuring the Environmental Safety of Coal-fired Power Plants for the Flue Gases Purification

Abstract

The article is devoted to solving of the pressing issue–provision of ecological safety of urban areas in flue gas purification of coal power plants and boiler houses. Use of the method for evaluating and selecting the maximum ecological efficiency and energy intensity value of purification of exhaust gases of thermal power plants and boiler houses of municipal services within the known physical and energetic approach allowed to obtain the parametric dependence of ecological efficiency and energy intensity value and determine the optimum parameters of hydrodynamic cleaning process with further designing of a new technical solution.On the basis of the simulation process and cleaning systems a new device of hydrodynamical (wet) cleaning the flue gases via control parameters significantly affecting the ecological efficiency and energy intensity value of the cleaning process was worked out. Moreover, control of parameters is carried out at the design of flue gases cleaning system, which allows to significantly optimize the choice of ways and means of reducing air pollution in urban territories. The obtained simulation results can be used to develop new or improve existing devices of hydrodynamic flue gases purification.
