Summerhill-certified powder fuels are safe and our burners are comparable to natural gas
Summerhill powder fuel is as safe to handle as is baking flour, confectioner’s sugar or pancake mix (all of which are explosible powders) . The standard dust control and mitigation measures used in grain elevators, coal mines and flour mills are adequate to prevent accidental dust explosions.
The only place where air and powder are mixed in a manner able to sustain a flame is in the heart of a Summerhill burner (see safety demonstration videos below).
Summerhill-certified powder is easily and safely transported and stored using standardized methods. Without an ignition point, without our burners, it is just sawdust - which is easily cleaned up with sweeping and water. An ongoing Cornell study of our burner system confirms the safety of the powder burning as well as that of the emissions.
The organic emissions (CO & VOCs)from Summerhill burners are almost as low as those from gas burners. Further, biomass in our system does not reach temperatures that would produce NOx (2000+ degrees F). The amount of ash depends on the ash content of the fuel. For example stem wood is less than ½ of 1% ash. What ash particles exist are in the micron range - they are not visible.
Powder Does Not Ignite Unless We Want It To...
