dc.description.abstractPopulation and their needs are growing day after day around the world, the thing that makes the amount of wastes increasing. Human developed many ways to manage this problem over the time including waste burial, burning, and others but this techniques have a lot of disadvantages on human and planet. Waste-to-energy plant is one of the technologies that found to manage waste problem by using the heat produced by the combustion of waste. Waste-to-energy plant depends basically on the principle of combustion and heat transfer principles as will be seen during the chapters of this project. . A simplified schematic is presented in Fig 1.1 in order to show the gas path and the various heat transfer sections. Urban wastes are presented on the furnace (section1) and the heat released from combustion is used to produce super-heated steam with high pressure, which feed a steam turbine, this steam is coming out from (EV1) which is installed in a zone full of the heat exhaust. In section 2 gas must stay at high temperature for a period of time to get rid of the pollutants. The exhaust gas is cooled down in (section 3). This obtained through the installation of an evaporator (EV2) for two purposes decreasing the gas temperature to be suitable for gas turbine plant uses and to produce super-heated steam with high pressure, which fed steam turbine. Super heater is a heat exchanger hold in (section 4) as shown in order to increase the temperature of steam to be suitable for steam turbine plant uses. Fig1. 1:Gas path in the system 2 The practical work related to the theories explained previously which as knows basically depends on zonal method that can be defined as a mathematical procedure used to analyze complex and realistic heat transfer problems. According to zonal method the furnace is divided into six main zone which are: Zone 1: the ground of the furnace. Zone 2: the walls surround combustion area. Zone 3: the walls surround gas area. Zone 4: the ceiling of the furnace. Zone 5: combustion zone, the zone at which combustion occurs. Zone 6: gas zone, the zone at which evaporator located which shown in fig1.2 mat lab program was used to apply the zonal method mathematically and from the other side to utilize the calculation. The purpose from using the zonal method is to know the temperature of the zone by knowing the interchange areas between zones and heat transfer rate between them, and to know the mass flow rate of water that should pass through the evaporator to get steam with temperature (250)en
