    Application of trigeneration with direct co-combustion of poultry waste and coal a case study in the poultry industry from Turkey
    (Vinca Inst Nuclear Sci, 2018) Topal, Hüseyin; Taner, Tolga; Altınsoy, Yelda; Amirabedin, Ehsan
    This study implies the significance of a trigeneration (TG) system, which converts a single fuel source into three useful energy products (i. e. power; heating, and cooling), and focuses on the simulation of a TG system with direct co-combustion of poultry wastes. The methodology is applied to a case study in northwest of Turkey to investigate how local poultry manure and environmental conditions can be effective in the production of energy. In addition, thermodynamic assessment of the system is performed, and the performance of the TG system is assessed by using energy, exergy, and parametric analysis methods. Poultry litter to coal ratio was 50% at the beginning, then poultry litter ratio in the mixture was increased to 90%, and this has led to less CO2 emissions from the TG and combined heat and power systems co-firing with poultry litter. With rice husk however the consumptions of TG and combined heat and power increased from 6533-6624 tonne per year, and 6549-6640 tonne per year, respectively. As a result, co-combustion of poultry waste can be considered as the best environmentally-friendly remedy to dispose chicken farm wastes, while catering the energy demand of the facility.

    Exergy analysis of a circulating fluidized bed power plant co-firing with olive pits: A case study of power plant in Turkey
    (Pergamon-Elsevier Science Ltd, 2017) Topal, Hüseyin; Taner, Tolga; Naqvi, Syed Arslan Hassan; Altınsoy, Yelda; Amirabedin, Ehsan; Özkaymak, Mehmet
    The effects of the above-mentioned parameters on exergy destruction, and CO2 emission of the power plant are determined for circulating fluidized bed power plant co-firing. The aim of this study is to perform thermodynamic analysis on can Circulating Fluidized Bed Power Plant (CFBPP) co-fired with olive pits. The results of this study also show that the total exergy damage of the plant is about 295 MW and the net exergy yield is 31.26%. The majority (252.40 MW) of exergy destruction occurs in the main boiler and accounts for 86.05% of the total exergy breakdown of CFBPP through exergy analysis. The results show that CFBPP has an effective feature of biomass supplement for exergetic performance and CO2 emissions. (C) 2017 Elsevier Ltd. All rights reserved.
