i am looking for a wood pellet micro combined heat and power system that is in the usa. does anyone know of one? or does anyone know of a heat driven system that can be hooked up to a standard boiler like the exhaust system on the boiler?
Take a look at the HastyHeat CHP wood pellet stove on ebay; it might be just what you are looking for:
It is a Combined Heat and Power Wood Pellet Stove TEG Thermal Electric Generator. For: RV, Trailer, Boat, Tent, Yurt, Cabin, Tiny Home, etc.
This Pellet Stove, Biomass Cogenerator can burn: wood pellets, Corn, compressed Algae, Pelletized Fuel, etc. It can be accesorized with various Options to produce: Electricity, Hot Water, Cooking, Light, and Heat.
This Furnace uses a Modular Lego Block Design with each block measuring just 3" wide 24" tall and 12" deep. It is Light Weight, Portable, Compact, and Tiny; at just 20# or 9 KG; yet capeable of producing enough heat to keep a 2000 square foot home cozy.
This Camp Stove is made using a laser cut Stainless Steel Rocket Nozzel Combustor. It is designed to handle the extreme >1200 F temps our pellet stove uses to cleanly and efficiently anhilate the wood pellets into high grade heat.
They do not exist because they would be too impractical.
There are many ways to produce power, however using a residential boiler due to its inefficiencies just would not be practical. I read somewhere that the output would be a mere 6%. While it would do some measurable amount of work in a home, not a whole lot for the cost of it. This is called (as you probably know) return on investment and once again it rears its ugly head.
I am not saying do nothing and buy every KW from the power company, I am just saying that windmills, micro-hydro, and solar give you far more watts for money spent...a better return on investment then trying to glean power from a residential boiler.
Thank you Christine for clarifying. You are indeed right. I was thinking of only the Stirling Engine set up in this capacity and not other factors.
Page 18 (conclusion) was an interesting read, but at the end of page 17 it seems as if I might be wrong and that there may be a few projects on the brink of commercialization. I hope so. I have plenty of biomass I could convert to electricity.
