Investigation of radiative heat transfer in freeboard of a 0.3 MWt AFBC test rig
Kozan, M; Selçuk, Nevin (2000-01-01)
Based on the analysis of measured data on flow rates, concentrations and temperatures taken during steady state operation of a lignite-fired 0.3 MWt Atmospheric Fluidized Bed Combustor (AFBC) test rig, radiative exchange in freeboard of the combustor was modeled by using a well-stirred enclosure model in conjunction with Radiosity-Irradiation Method (RIM). Radiative properties of the particle laden combustion gases were calculated by assuming grey radiation behaviour for both particles and gas, and using Le...
Investigation of combustion characteristics of indigenous lignite in a 150 kwt circulating fluidized bed combustor
Batu, Aykan; Selçuk, Nevin; Department of Chemical Engineering (2008)
Coal is today the fossil fuel which offers the greatest proven reserves. Due to increasingly stringent environmental legislation, coal fired combustion systems should be based on clean coal combustion technologies. For clean and efficient energy generation from coal reserves, the most suitable technology known to date is the ‘Fluidized Bed Combustion’ technology. Applications of circulating fluidized bed combustion (CFB) technology have been steadily increasing in both capacity and number over the past deca...
Investigation of mechanical property changes after MIG welding of (7XXX) series aluminum alloys
Okay, Sena; Ögel, Bilgehan; Batıgün, Caner; Department of Metallurgical and Materials Engineering (2016)
There is an increasing demand for aluminum alloys not only in aerospace industry but also in automotive industry due to its low density. Welding is the most effective and commonly used joining technique in those industries, therefore, aluminum welding plays an important role. 7039 aluminum alloy, is a high strength alloy and it is suitable for armor applications. Like other aluminum alloys, after MIG welding, remarkable decrease in strength is observed and therefore applications are restricted. The aim of t...
