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 measured in the flue gas during combustion experiments. By changing the operating parameters (excess air ratio, fluidization velocity, and fuel feed rate), the variation of emissions of various pollutants was studied. Temperature distribution along the bed was measured with thermocouples.

Olive cake combustion in a circulating fluidized bed
Topal, H; Atımtay, Aysel; Durmaz, A (Elsevier BV, 2003-06-01)
In this study, a circulating fluidized bed of 125 mm diameter and 1800 mm height was used to find the combustion characteristics of olive cake (OC) produced in Turkey. A lignite coal that is most widely used in Turkey was also burned in the same combustor. The combustion experiments were carried out with various excess air ratios. The excess air ratio, l, has been changed between 1.1 and 2.16. Temperature distribution along the bed was measured with thermocouples. On-line concentrations of O-2, SO2, CO2, CO...
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 peach and apricot stone with coal in a bubbling fluidized bed
Atımtay, Aysel (2008-02-01)
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 chang...
AIR OXIDATION OF TURKISH BEYPAZARI LIGNITE .1. CHANGE OF STRUCTURAL CHARACTERISTICS IN OXIDATION REACTIONS AT 150-DEGREES-C
AZIK, M; YURUM, Y; GAINES, AF (American Chemical Society (ACS), 1993-05-01)
The oxidation of Beypazari lignite was carried out in air at 150-degrees-C for up to 168 h. Oxidized samples were withdrawn from a ventilated oven at different periods of time and characterized by elemental analysis, diffuse reflectance Fourier transform infrared (DRIFT), solid-state C-13 CP/MAS/TOSS NMR, and pyrolysis mass (Py-MS) spectroscopies. It was found that oxidation influenced the organic structure and the inorganics at different periods of the oxidation. Iron(II) sulfate was formed in 24 h, during...
ELECTROKINETICS OF OXIDIZED COAL
SARIKAYA, M; OZBAYOGLU, G (Elsevier BV; 1990-01-01)
Electrokinetic measurements were carried out in order to determine the properties of oxidized coal surfaces over a wide pH range both in the presence and absence of various metal ions and flotation collectors. It was found that polyvalent cations, such as Fe++, Fe+++ and Al+++ decreased the zeta potential to zero and then reversed the charge. In the presence of cationic collectors, the negative value of zeta potential of oxidized coal was driven positive, below 9.3 to 10.9 depending on the type and concentr...
