Heat recovery on an engine<\/strong> refers to the capture and reutilization of heat energy which is normally wasted to radiators<\/a>. This process,increasingly common today, improves total system efficiency and return on investment. New plants designed for this purposes are usually called cogeneration plants<\/strong><\/a>.<\/p>\n

\"\"<\/a><\/p>\n

<\/p>\n

Reciprocating engines energy coming from fuel is converted to:
\n\u2022 30-40% mechanical power
\n\u2022 20-40% rejected to the jacket water
\n\u2022 30-40% rejected to exhaust
\n\u2022 5-7% radiated to the environment
\nthese data depends from kind of engine and manufacturer.<\/p>\n

The heat rejected by the jacket water<\/strong> can be totally recovered.
\nThe 50-70% of the exhaust rejected energy, in economically recoverable, more then this value is not achievable, due to problem of low temperature of exhaust and corrosion resistance of heat exchangers<\/strong><\/a>.<\/p>\n

Total heat recovery results in approximately 75-80% efficiency<\/strong>.
\nHeat recovery design best suited for any installation depends on many considerations, both technical and economic.
\nWe need to keep in mind that the primary function of any design is to cool the engine. The engine must be cooled even when heat demand is low, but power is still required.<\/p>\n

Usually energy is recovered producing hot water or superheated water, sometimes producing steam.
\nTo achieve recovery on engine the best solutions are:
\n\u2022 Plate heat exchangers<\/a> for water jacket recovery
\n\u2022 Special shell and tube heat exchanger<\/a>s for exhaust recovery.<\/p>\n

\"\"<\/a>Heat Balance<\/strong>
\nThe typical heat balance for an engine is shown in the figure below.<\/p>\n
