This work investigated the particulate matter formation during co-combustion of biomass with coal.Olive residue in 212-300 μm was chosen as agricultural waste biomass, and Tunçbilek lignite in 106-125μm as the coal. The biomass was thermally pretreated to assess the influence of the pretreatmenttemperature on particulate matter formation during co-combustion. Specifically, the olive residued wastorrefied (at 275 ºC) and pyrolyzed (at 500 ºC) using a tubular oven. The biomass-coal blends in a 50:50wt.% ratio were co-fired in a drop tube furnace operated at 1200 ºC, heating rate of ~104 ºC/s, residencetime of ~3 s, and dry air atmospheric conditions. The results showed that co-combustion resulted inclear reduction of PM2.5 emission to values close to those of the biomass fuel, and below the predictedvalues. Specifically, combustion of olive residue – Tunçbilek lignite, torrefied olive residue – Tunçbileklignite, and olive residue char – Tunçbilek blends resulted in 646, ORT-TL in 408, and 559 mg / MJ input,respectively. Moreover, the mechanisms responsible for the formation of PM2.5 during biomass and coalcombustion were found applicable to biomass-coal blends.

Influence of biomass thermal pre-treatment on the particulate matter formation during pulverized co-combustion with lignite coal Magalhaes, Duarte; Kazanç Özerinç, Feyza (2022-01-15) This work investigated the particulate matter formation during co-combustion of thermally pre-treated biomass with coal. Olive residue was chosen as agricultural waste biomass, and Tunçbilek lignite as the coal. The biomass was thermally pretreated to assess the influence of the pretreatment temperature on particulate matter formation during co-combustion. Specifically, the olive residue was torrefied (at 275 °C) and pyrolyzed (at 500 °C) using a tubular oven. The biomass-coal blends in a 50:50 wt% ratio we...
Effects of municipal wastewater treatment sludges on some soil properties in field experiment Akça, Muhittin Onur; Farasat, Shima; Namlı, Ayten; Sanin, Faika Dilek (null; 2018-07-05) Introduction: The agricultural use has become the principal disposal method for sewage sludge in Europe, agricultural use accounts for 37% of the total sludge produced and it is expected that stabilized sludge will be used in agriculture in large quantities in the next years in many important EU member states. The reuse of treated municipal sewage sludge (biosolids) in agriculture provides the nutrients and micronutrients (such as N, P, K but also Fe, B, Cu and Ni among others) necessary for plant and crop ...
Influence of hydrothermal treatment on selenium emission -reduction and transformation from low -ranked coal Ullah, Habib; Chen, Baoliang; Shahab, Asfandyar; Naseem, Faiza; Rashid, Audil; Lun, Lu; Yousaf, Balal; Khan, Sangar (2020-09-01) One of the key environmental limitations in coal usage is selenium emission whose removal is focused in this study. We employed hydrothermal treatment to remove Se element and upgrade low rank Huainan coal at 200-300 degrees C. Pyrolysis temperature given during coal treatment was evaluated to simulate coal transformation into high-rank industrial grade by emphasizing O/C ratio, removal of oxygen functional groups and moisture and chemical structure stability. Following hydrothermal treatment, different cha...
Influence of fly ash composition on non-gray particle radiation in combusting systems Ates, CİHAN; Selçuk, Nevin; Külah, Görkem (2018-08-01) In this study, chemical composition dependency of both radiative properties of ash particles and radiative heat exchange are investigated for conditions typically encountered in industrial coal-fired furnaces. For that purpose, chemical composition dependent / independent complex index of refraction models are utilized to evaluate (i) spectral particle absorption efficiencies, scattering efficiencies and asymmetry factors, (ii) particle cloud properties representing pulverized coal fired furnaces (PC-Fired)...
Effects of operational parameters and ultrasonic pretreatment on supercritical CO2 extraction of diesel fuel from soil Guvenc, A; Mehmetoglu, U; Mehmetoglu, T (Informa UK Limited, 2004-01-01) Supercritical fluid extraction (SFE) using CO2 was performed on soil material artificially contaminated with diesel fuel. Raising the temperature from 313 K to 343 K caused the recovery efficiency to increase from 52 to 76%. Pressure and CO2 flow rate were found to be less important. As expected, increasing extraction time resulted in higher recoveries. Ultrasonic pretreatment of the soil material was found to be very effective, possibly due to disrupting the strong interaction bonding between soil matrix a...
