In this study a bubbling fluidized bed combustor (BFBC) having an inside diameter of 102 mm and a height of 900 mm was used to investigate the co-combustion characteristics of peach and apricot stones produced as a waste from the fruit juice industry with coal. A lignite coal was used for co-combustion. on-line concentrations of O-2, CO, CO2, SO2, NOx and total hydrocarbons (CmHn) were measured in the flue gas during combustion experiments. Variations of emissions of various pollutants were studied by changing the operating parameters (excess air ratio, fluidization velocity, and fuel feed rate). Temperature distribution along the bed was measured with thermocouples.

Peach and apricot stone combustion in a bubbling fluidized bed Kaynak, B; Topal, H; Atımtay, Aysel (Elsevier BV, 2005-07-25) In this study, a bubbling fluidized bed combustor (BFBC) of 102 mm inside diameter and 900 mm height was used to investigate the combustion characteristics of peach and apricot stones produced as a waste from the fruit juice industry. A lignite coal was also burned in the same combustor. The combustion characteristics of the wastes were compared with that of a lignite coal that is most widely used in Turkey. On-line concentrations of O(2), CO, CO(2), SO(2), NO(X) and total hydrocarbons (C(m)H(n)) were measu...
Agro-waste combustion in a circulating fluidized bed Atımtay, Aysel (2005-05-13) In this study a circulating fluidized bed combustor (CFBC) of 125 mm inside diameter and 1800 mm height was used to investigate the combustion characteristics of peach and apricot stones produced as a waste from the fruit juice industry. A lignite coal was also burned in the same combustor. The combustion characteristics of the wastes were compared with that of a lignite coal that is most widely used in Turkey. On-line concentrations of O-2, CO, CO2, SO2, NOX and total hydrocarbons (CmHn) were measured in t...
Co-firing of steam coal with high sulfur content lignite in a bubbling fluidized bed combustor Selçuk, Nevin; Altindag, Hakan (2005-05-25) Combustion and emission behavior of 100 % steam coal (SET 1) and a mixture of 80 % by weight steam coal and 20 % by weight local lignite, characterized by high sulfur and ash contents, (SET 2) were investigated in the 0.3 MW, Middle East Technical University (METU) Atmospheric Bubbling Fluidized Bed Combustor (ABFBC) Test Rig. Experiments were performed with limestone addition at various Ca/S molar ratios with fines recycle. In both sets of experiments, parameters other than Ca/S molar ratio were held as ne...
Co-combustion of olive cake with lignite coal in a circulating fluidized bed Atımtay, Aysel (Elsevier BV, 2004-05-01) In this study, olive cake (OC) was co-fired with coal in a circulating fluidized bed of 125 mm diameter and 1800 mm height. Olive cake is a waste from olive oil production. A lignite coal that is most widely used in Turkey (Tuncbilek lignite) was used together with OC and the combustion characteristics of olive cake (OC) + coal mixture were investigated. The combustion experiments were carried out with various excess air ratios. The excess air ratio, A, has been changed between 1.1 and 2.16. Temperature dis...
Co-combustion of coal and olive cake in a fluidized bed with limestone addition and freeboard extension Akpulat, Onur; Atımtay, Aysel; Department of Environmental Engineering (2009) In this study, flue gas emissions and combustion efficiencies during combustion and co-combustion of olive cake and coal are investigated in a bubbling fluidized bed with an inside diameter of 102 mm and a height of 900 mm and 1900 mm. Tunçbilek lignite coal and Edremit olive cake were used in the experiments as fuels. Temperature distributions along the combustion column were continuously measured. Flue gas concentrations of O2, CO, SO2 and NOx were measured during combustion experiments. Four sets of expe...
