Improving the Efficiency of Fuel Usage in New Coal Technologies

Abstract

<p>The increase of the fuel usage efficiency by application of new coal technologies, modern automation and control meanings were considered in the paper. The results of comprehensive researches of promising coal technology efficiency are given. It is shown that their efficiency is 1,15-1,7 times higher than conventional coal unit one. The parameters deviation influences on fuel overexpenditure at unsteady state were researched. It provides exact cause-and-effect relation between automation means and fuel expenditure of thermal power plant. Unit operation on boiler stored energy at emergency is researched. It is shown that the automation reduces significantly recovery time of unit normal load thereby it reduce the damage caused by emergency. Besides there were shown the effect of power generating equipment on environment, social infrastructure and health care. There are given reasonable ratio between infrastructure and health care costs that occur in a big city where thermal power plant was installed.</p
