RECOVERY OF SOME ELEMENTS FROM SOLID WASTTES PRODUCED FROM FUEL COMBUSTION IN POWER PLANTS

Abstract

This thesis consists of four chapters arranged as follows; Chapter (1) Introduction The introduction includes the specification and types of ashes produced from combustion process. It also discusses the world-wide and local bad impact result from using of fossil fuel, especially heavy fuel oil, as fuel in electricity production. Some methods used in recovery of metals as nickel and vanadium from fly and bottom ashes were explained with. Literature review of this thesis is also mentioned that explains that there is little searches in recovery of metals from bottom ashes , as far as I know. The aim and the benefits of the work was explained in this chapter Chapter (2) literature review This chapter includes pre studies and researches in energy field as general and also the types of fuel .Some of the bad impacts result from using fossil fuel and the suitable solution for this impacts were studied. The quantity of ashes produced locally and globally from combustion process and the studies for recover and reuse of some elements from ashes were mentioned and explained. The following issues were covered: 1-Fuel types 2-Steam power plans
