The objectives of this study are to investigate the flow and combustion process of coal combustion in an ultra- supercritical critical boiler. This paper will also investigate the exhaust temperature of the flue gas at the back-pass side of the ultra supercritical coal fired boiler. Pulverized coal is fired inside the boiler at combustion chamber area to ignite and produce enough heat to be transfer and absorb by the water inside the boiler tube wall. Instability of fire ball temperature may cause temperature fluctuation to the boiler water tube wall. These fluctuations in fire ball temperature and inconsistent temperature deviation inside the boiler will reduce the efficiency of heat exchanger process between flue gas and water tube in the boiler. Hence, this project is carried out to understand more about the properties and behavior of flue gas flow through boiler passage. There are many type of tube that align in the boiler, such as super-heater tube, re- heater tube, and so on that can be design as part of the boiler component but for this work, only focused on boiler housing and the area in which the path of flue gas covers only. Background study and literature review are carried out to understand more about the work. Then SOLIDWORKS 2016 is used to design the three dimensional boiler frame construction since the boiler structure is difficult to construct using GAMBIT. After that, GAMBIT is only used to carrying on the mesh and grid division, then selecting the appropriate model of mathematics and physics and the suitable parameter and the variable, and setting up the boundary condition. Finally basing on a foundation of the FLUENT is used to carry out the three-dimensional numerical simulation of furnace combustion, receiving the distributions of temperature region, velocity region, and gas components region in the furnace. Indeed, even with the design configuration, the temperature flow inside the boiler passage to the super-heater is not balance. The outcomes determine that that the uneven temperature circulation at back-pass of boiler height exists were depends on the type of coal used. It is recommended that the high gas temperature at furnace back-pass could be improved by working at low tilt edge of the burner nozzle. 2024-11-27T02:23:47Z 2024-11-27T02:23:47Z 2017 Resource Types::text::Final Year Project https://irepository.uniten.edu.my/handle/123456789/35158 en application/pdf
