In this study, co-combustion of woodchips and Bursa-Orhaneli lignite was carried out in a circulating fluidized bed combustor, 6 m long and 108 mm inside diameter. Co-combustion of lignite and woodchips was performed in order to investigate the effect of secondary air ratio (SAR) on the flue gas emissions. The woodchips content of the fuel mixture was 30% and 50% by wt. Secondary air (SA) was supplied to the combustor from five different locations along the combustor and at several SARs. During the combustion experiments, CO2, CO, O-2, NO, and SO2 emissions in the flue gas were continuously measured and recorded by ABB-AO 2000 flue gas analyzer.

Emission characteristics of co-combustion of a low calorie and high sulfur-lignite coal and woodchips in a circulating fluidized bed combustor: Part 1. Effect of excess air ratio Varol, Murat; Atımtay, Aysel; OLGUN, HAYATİ; Atakül, Hüsnü (2014-01-01) In this study, co-combustion of Bursa-Orhaneli lignite and woodchips mixtures containing 10%, 30% and 50% by wt. of woodchips was studied in a circulating fluidized bed combustor in order to investigate the effect of excess air ratio (k) on the flue gas emissions. The combustor has an inside diameter of 108 mm and a height of 6 m. The temperature of the combustor is kept at 850 degrees C during the combustion tests. During the combustion tests, CO, O-2, NO, and SO2 emissions in the flue gas was continuously...
Emission characteristics of co-combustion of sewage sludge with olive cake and lignite coal in a circulating fluidized bed Toraman, OY; Topal, H; Bayat, O; Atımtay, Aysel (Informa UK Limited, 2004-01-01) In this study, a circulating fluidized bed (CFB) of 125 mm diameter and 1800 trim height was used to find the combustion characteristics of sewage sludge (SS) produced in Turkey. Sludge + olive cake, and Sludge + lignite coal mixtures were burned separately. Various sludge-to-lignite coal and sludge-to-olive cake ratios (5/95, 10/90. 15/85, 20/80) were tried. On-line concentrations of major components (O-2, SO2, CO2, CO, NOx, CmHn) were measured in the flue gas, as well as temperature and pressure distribut...
Combustion of agro-waste with coal in a fluidized bed Atımtay, Aysel (2010-02-01) In this study, a review of the studies done on the co-combustion of some agro-waste in a bubbling fluidized bed combustor (BFBC) having an inside diameter of 102 mm and a height of 900 mm is given. The agro-waste used to investigate the co-combustion characteristics were peach and apricot stones produced as a waste from the fruit juice industry, and olive cake produced as a waste from the olive oil industry. These are typical wastes for a Mediterranean country. A lignite coal was used for co-combustion. On-...
Investigation of co-combustion of coal and olive cake in a bubbling fluidized bed with secondary air injection Atımtay, Aysel (2009-06-01) In this study, a bubbling fluidized bed of 102 mm inside diameter and 900 mm height was used to burn olive cake and coal mixtures. Tuncbilek lignite coal was used together with olive cake for the co-combustion tests. Combustion performances and emission characteristics of olive cake and coal mixtures were investigated. Various co-combustion tests of coal with olive cake were conducted with mixing ratios of 25%, 50%, and 75% of olive cake by weight in the mixture. Operational parameters (excess air ratio, se...
Investigation of combustion characteristics of biomass and coal mixtures in a circulating fluidized bed combustor Varol, Murat; Atımtay, Ayse; Department of Environmental Engineering (2013) In this study, combustion and co-combustion tests of Bursa/Orhaneli lignite with two biomass fuels (olive cake and woodchips) were carried out in a laboratory scale Circulating Fluidized Bed (CFB) combustor, 6 m high and 108 mm inside diameter, in order to investigate the effect of excess air ratio (l), secondary air ratio (SAR) and location of secondary air injection along the combustor wall on the emissions. Optimum l and SAR was determined for each test. The flue gas emissions were compared with limits i...
