Abstract

In this paper, biogas reactor heating system using power plant
waste heat as a heat source is conducted in the first time in
literature. The feasibility of utilization of biogas for electricity
and increase in efficiency of overall system electricity production
are investigated. Can power plant in Çanakkale, Turkey is chosen for
the investigation in this case study. Can power plant releases 195MW
thermal energy to air in condenser unit with relatively low
temperature (43°C). Given temperature range is ideal for mesophilic
bacteria growth in digestion process during the biogas production
process. 39.8MW biogas based electricity production potential is
available for Can power plant condenser waste heat. Overall
electricity production energy efficiency can be increased by 9.7%.
This analysis will provide a very good example to recover the
released high amount of waste heat with low temperature for many
power plants. Motivation of authorities on huge capacity biogas based
electricity production can be increased by designing such kind of
applications.
