Abstract:
In recent years, due to the increasing concern over energy shortage and global warming, the interest in low grade heat recovery from industrial processes has grown dramatically (IEA, 2010). Several studies have underlined the potential of small-capacity ORC power plants for waste heat recovery (WHR) applications (Verneau, 1979). For such systems accurate dynamic modeling represents an important tool in particular when control issues are considered (Colonna and van Putten, 2007) (Casella et al., 2013). This paper presents a dynamic model of an ORC system, validated both in steady-state and transient conditions via experimental data from a 10 kWe waste heat recovery ORC system with a screw expander.
