Here is a link to a very cool innovative steam engine design: http://www.greensteamengine.com/. One big advantage of this design is that it scales down very nicely, suitable for small-scale TLUD burners.
I saw it in operation several years ago. At the time he was looking for licensees.

I'm thinking the reason is that to convert to electricity one needs 1) a very clean syngas 2) an expensive motor and 3) costly up-keep. The generator is a onetime purchase with low maintenance. So why not use a steam engine to convert the flame to electricity? Perhaps not as efficient but all you are doing is heating water so the gas need not be as clean as when drawn into an internal combustion engine.
