The use of biogas by a cogeneration system (CGS) is a promising technology as an efficient method of energy utilization. Sewage treatment plants (STPs) are facilities that have been continuously producing biogas, and therefore the potential of application of a biogas-fuelled CGS in an STP is estimated to be very high. However, there have been few reports on efficient utilization of biogas by a CGS, especially in cold regions. Since ambient temperature in a cold region is low and varies greatly, heat demand in the STP is also great and varies greatly throughout the year. Thus, auxiliary components such as a boiler, heat pump and gas storage system are also required to cover the total heat demand throughout a year. In the present study, adopting an actual STP in a cold region and a micro gas turbine as the CGS prime mover, performance of a biogas-fuelled CGS was investigated. The performances of four possible arrangements of the CGS with different auxiliary components were compared to the performance of a conventional system. It was found that all CGS arrangements could cover the total heat demand by only using biogas produced in the facility. The CGS arrangements could reduce electrical power demand by 23~31%, recover 74~78% of the energy of biogas produced, and utilize almost 100% of the biogas. The CGS arrangements with a heat pump were more efficient than the CGS arrangements with a boiler. CGS arrangements that include a gas storage system will enable efficient utilization of biogas and recovered exhaust heat.

Original scientific paper The system of separate production of heat energy from a boiler and cooling energy from a compression refrigeration unit powered with electrical energy from an external network can be replaced with a CCHP system based on the operation of a gas turbine and absorption refrigeration unit. For this purpose, models of the system were derived through the use of the object-oriented programming language Modelica, on the basis of which steady-state simulations were carried out, as well as technical-economic and the sensitivity analysis of the system, in relation to the changes of influential parameters such as coefficient of performance, the boiler efficiency, the ratio of the electric load, costs of electrical energy, fuel prices and investment costs. Developed system model is intended to be used in further research for dynamic simulations with implemented dynamic boundary conditions.

Razvijeni model sustava koristiti će se u istraživanjima koja slijede za dinamičke simulacije s uvedenim dinamičkim rubnim uvjetima.

“…Jaber et al [5] proposed the use of the evaporative cooling system to boost the output power and to enhance the efficiency of the gas turbine unit. Basrawi [6] investigated the effect of ambient temperature on the performance of micro gas turbine with cogeneration. They observed that when ambient temperature increases, electrical efficiency of micro gas turbine decreases.…”
