Corn and pellet stoves and furnaces article
Pellet stoves and furnaces use corn kernels as a source of renewable
energy. Many stoves can use several types of fuel: corn, cherry
pits, wood pellets, etc.
They first became popular during the oil shortages of the 1970s.
As people became used to higher prices their popularity grew slowly.
They became more sophisticated, and more physically attractive.
Most stoves are now quite attractive. Commercial models are available,
which can heat large buildings, or be used to generate electricity.
Pros
The chief attraction of these stoves is fuel price. Corn kernels
purchased in bulk, can cost only 25% what heating oil, natural gas,
or propane can. Because it is a natural pellet it is more economical
and is in greater supply than manmade pellets in most areas. Wood
pellets were in short supply, in many areas, in 2005. Pellet manufacturers
struggled to keep up with demand. Corn remained inexpensive and
readily available in corn country. By the year 2005, a standard
price would be $1.80 a bushel for bulk corn. Millions of bushels
of corn were readily available in corn country. Transportation and
marketing of corn lagged behind demand however.
In the midwest, corn burning stoves have reached heightened popularity
due to the 2005 rise in fuel prices. Waiting lists are formed in
the fall, as the manufacturers cannot keep up with demand in the
colder months.
Some corn stoves do not produce ash, the corn by-product forms
a solid block called a "clinker" that needs to be dropped
into an ash pan every 1-3 days. There are also some models of stoves
that have an agitator that continuously grinds the clinker down
to ash.
Comparison with ethanol
Ethanol use creates a demand for corn, but requires expensive equipment
and handling and transport. Corn kernels can go straight from the
combine harvester into a corn stove, if dry enough. Moisture must
be no more than 15%. 10% moisture corn is ideal, as is corn that
is cleaned more thoroughly. If bagged corn was marketed in non-corn-producing
areas, it would probably still be cheaper than pellets in most areas
due to the natural pellet advantage.
Habits and inertia on the part of home and business owners, may
be a reason why corn and pellet stoves and furnaces are not more
widely sold and used. This applies especially to electrical generation
using large corn furnaces.
