Garnification, I am interested in buying Garn-2000 boiler.Now I know you made your garn from scratch. As far as Garn knowledge concerns you must the most knowledgable person to ask about modification to garn.Here is my question : Is it possible to add some kind of augur system to garn loading chamber where by the Garn will get continuous supply of woodchip at certain amount by controling the speed of augur motor? is it possible to put some kind of hole in the garn for this purpose without losing too much of Garn's efficiency? or Is it possible to add blower system to garn whereby it can blow certain load of wood chip at certain time interval and close the hole when it is not blowing chips into boiler ? I am asking this because woodchip supply for me will be lot cheaper option for me than hardwood as there some sawmills around here I am talking to and they are ready to supply woodchip at $30-40 a ton delivered.Hardwood is about $225 per cord.I can also have option of using corn cob and sawdust.Hardwood should remain primary fuel and augur system should add some alternative like wood chip or sawdust to hardwood fuel.My average oil consumption for last 3 years has been between 5000 and 6000 gallons for heating and dHW for approximately 8000 sf commercial building. When I was looking around for biomass boiler I found goliath-110 ( http://www.newhorizoncorp.com/goliath.html ) on the web.it looks like nice system but I like Garn as a boiler better because it has built in tank,more btu's and it is less complex sytem than other boilers.also it is approved in my town.may be I can use goliath's fuel supply system with Garn.best of both worlds ! Anyone who has feedback will be appreciated.
