We’re using straw.
The estimate is that one bale of straw is 200 dollars worth of electricity or about 200 dollars worth of natural gas.
The cost of heating with wheat straw is similar to that of using coal but straw fuel is about 90 percent less expensive than heating with either natural gas or electricity.
We put 16 bales on a conveyer, the conveyer feeds them into the system. We have a shedder that shreds the bales into finer particles and delivers it into the primary combustion chamber where we essentially do a low temperature burn, or create smoke.
Then we take that smoke and send it into a secondary chamber, or afterburner, and we burn it in there at two thousand degrees Fahrenheit which then means we get full and complete combustion, clean gas that we then move over into our heat exchanger to heat water. The water, in turn, heats the facilities. via FarmScape
