Biogas engines

Post by simon___482 »

Is it possible to run a Stirling engine off the waste heat from a
recipricating engine or a gas flare? I am involved in running engines
that use methane as a fuel and also use flares which again are
fuelled by methane. Any biogas application is suitable for the
engines and flares. The temperature coming off the top of a flare is
approximately 1200 degrees C and the engines I think 600 degrees C.

Running Stirling engines on waste heat

Post by stan.hornbaker »

Possible, yes. Prudent or economical, no. There are no Stirling engines on the market today, with a reasonalbe price tag, for general purpose use. Those available for purchase today are for niche applications and priced accordingly.

If you can take the time to read all of the posts and replies on the Power-producing Stirling engines and Wast Heat Recovery Forums you shoud get a sense of the problems involved.
