Hydrodynamics of a fluidized bed co-combustor for tobacco waste and coal.
The fluidization characteristics of binary mixtures containing tobacco stem (TS) and cation exchange resin (a substitute for coal) were studied in a rectangular bed with the cross-section area of 0.3 × 0.025 m(2). The presence of herbaceous biomass particles and their unique properties such as low density and high aspect ratio resulted in different fluidization behaviors. Three fluidization vel...
متن کاملCo-firing Performance of a Retrofitted Oxy-Combustor burning Coal/Biomass Blends: Experimental and Simulation Study
Oxy-fuel combustion is a clean coal technology based on firing fuel in an enriched oxygen atmosphere to obtain a high CO2 concentration in the off-gases. This technology can be combined with the co-firing biomass and the use of blends of coal and biomass can compensate for the fact that the gas properties in the furnace in an oxycombustion process differ from the air-firing case (oxy-firing flu...

15 صفحه اولdevelopment of feminist poetics in adrienne rich
اشعار ریچ، به عنوان اشعاری که همیشه در حال تغییر و دگرگونی هستند، تجسمی از رشد و دگرگونیِ انسان هستد. پایان نامه ی حاضر، با تمرکز بر روی مراحل سیر شعری ریچ از تغییری در دنیا به عکس هایی فوری از یک عروس، سپس به شیرجه به درون کشتی شکسته و در نهایت به صبری عجیب مرا تا اینجا آورده، به بررسی این مراحل در قالب نظر شوالتر در رابطه با سه مرحله ی پیشرفت ادبی زنان یعنی مرحله ی زنانه، زن گرا و زن محور می پ...
15 صفحه اولEffect of co-combustion of chicken litter and coal on emissions in a laboratory-scale fluidized bed combustor
Article history: Received 1 October 2006 Received in revised form 20May 2007 Accepted 20 June 2007 Co-combustion of chicken litter (CL) with coal was performed in a laboratory-scale fluidized bed combustor to investigate the effect of CL combustion on pollutant emissions. The emissions of major gaseous pollutants including CO, SO2, H2S and NO and temperature distribution along the combustor wer...
