Economic evaluation for adoption of cogeneration system

Optimum Sizing of the Prime Mover in a Medium Scale Gas Turbine CHP System

“…CO2 emissions = energy content of fuel X CO2 emission factor X combustion factor X 1000 (4) where CO2 emissions are in tons of CO2 (t CO2), energy content of fuel is in gigajoules, CO2 emission factor is in kilotons COT/GJ (508 X 10-'' for New South Wales (NSW) natural gas), and combustion factor is 0.995, CH4 emissions = energy content of fuel X CH4 emission factor X 1000 X 21 (5) where CH4 emissions are in tons of CO2 equivalent, energy content of fuel is in gigajoules, and CH4 emission factor is in kilotons CH4/GJ (8X 10"^ for turbine and 1 X 10"'" for boiler).…”

“…Thermal or thermo-economic analysis of gas turbine based CHP systems in order to assess the feasibility of installing new systems, determining the optimal configuration of systems, or evaluating the performance of an existing system has been the subject of interest in recent years [2][3][4][5][6]. Furthermore, there is some literature dealing with the effect of different operating conditions of gas turbines such as reheat and intercooling on the performance of CHP systems [7,8].…”

Feasibility and flexibility for a trigeneration system

“…seasonal changes) or even in a day [20][21][22]. The monthly and hourly maximum utility demands in the commercial building complex are shown in Fig.…”

Feasibility study of cogeneration in a plywood industry with power export to grid

“…In the study of Biezma and Cristo [11] three evaluation methods; net present value (NPV), internal rate of return (IRR) and payback period (PP) are applied to the selection between two CHP units for a tyre factory in Spain. Oh et al [12] presented an optimal planning for gas turbine cogeneration system to find whether the adoption of the system to an office building or hotel in Seoul, Korea is profitable or not. Duval [13] reported a 3.2 MW wood fired cogeneration plant for a plywood industry in Pulau Borang, Palembang, Indonesia owned by PT Kurnia Musi Plywood Industries since 1995.…”
