[Stoves] Press release and powerpoints from Design Challenge

Tue Apr 12 17:45:33 CDT 2016

Dear Friends of Pellet Stoves

This just arrive from the Alliance for Green Heat. It is talking about the result of the Pellet Stove Design Competition that was held last week at the Brookhaven National Laboratory on Long Island.

A number of wonderful presentations were made – not all are up yet on the link below but some are.

There were three contenders selected for this year’s competition and they received extensive testing using two completely different approaches.  Two were reasonably conventional updraft burners, one with an unusual elongated bowl-shaped combustion chamber with no holes in it. The other was a hopper-fed downdraft stove with a 30 Watt TEG mounted on it. It was very compact, the combustion chamber being no more than 80mm in diameter and mostly blocked with a large disk. The depth of fuel between the primary air entrance and the disk supporting the fuel could be adjusted allowing the total air to be controlled vis-à-vis the total burning surface. In effect, were it a conventional TLUD, it had a fixed bed of fuel with a variable height for the primary air entrance, which was not through the fuel.

There is no reason it could not be done upwards instead of downwards.

The fuel feeding was much like Alex English’s home heating stove, but downdraft instead of Alex’s crossdraft. I think if Alex’s stove had been entered it would have won a prize of some kind.

Well done, winners.
