Burn Corn Pellets to Produce Heat Energy
For most people, the pellet made from corn is a kind of commendable
feed for various animals. However, corn pellet is also an alternative
biomass fuel with an increased availability of fuel resources, generally
used to create a source of heat for residential and sometimes industrial

spaces.

Corn pellets come from a renewable source as with wood pellets, which,
together with their cleaning burning, makes them eco-friendly. At the
same time, burning corn pellets creates a wonderful sweet scent. They
can offer the same cost-effective heating as wood pellets.

Corn Pellet Fuel Application
1. For home heating: corn pellet fuel is commonly used for domestic
heating for its high burning rate.
2. For biomass industry boiler: as a kind of main fuel for industry boiler,
corn pellet fuel can replace coal, gas, oil, etc. with less environment
polluting.
3. For power station: in thermal power plant, burning 1,000 tons of corn
pellets can reach a working efficiency that 8,000 tons of coal has.
4. For other industries: corn pellet fuel can be utilized to provide heat

power for textile, printing, chemical, medicine, food, etc. industries.

Why Take Corn as the Raw Materials for Making Bio-fuel
1. As an ideal natural pellet fuel, corn can grow fast in wide regions that
suits for its plantation, which means a consistent availability of fuel
resources.
2. Maize has a high calorific value of 16.3 MJ/KG.
3. There is no smell and irritation fume, low pollutants and emissions
when maize burns, so it has no negative effects on the environment.
4. The ash produced after burning can be used as additive for the gardens
to improve the soil quality.
5. Corn is easy to store. It can be stored in any dry and clean place with
rodents and pests avoided.
6. The low-grade and damaged corn also can be used to produce pellet
fuel, which improves the use ratio of corn, reducing a waste.

Make Use of Corn Pellets or Wood Pellets?
To produce heat, there are many kind of traditional methods, such as
electricity, gas, and oil, etc. but they need large amount of investment.
With developing new-type energy that is eco-friendly and renewable,
there are two kinds of alternative sources of fuel emerging, wood pellets
and corn pellets. Both wood pellets and corn pellets can be used as fuel,
and the following factors can be take into consideration to decide what
pellets to employ, the corn pellet or the wood pellet?
1. Feature
Corn pellets are made of shelled-compressed corn seed; wood pellets are
made of compressed woody materials.
2. Availability
The availability of corn pellets and wood pellets depends on the location
where has abundant raw materials for both of them.
Wood pellets are made of sawdust, wood chips, bark, agricultural crop
waste, and other organic materials, so wood pellets are readily available
in areas with rich wood resources, such as the northeast and northwest
areas of U.S.
Corn pellets are obviously readily available in areas where corn is grown.
In Midwest of America, the corn pellet is easy and cheap to obtain. But in
areas where corn has no much plantation or has to be bought in, the cost
may be a little higher.

3. Performance
Wood pellets are burned in pellet stoves, but corn pellets should be
burned in corn stoves or multi-fuel stoves. The corn stove is
specially-designed for corn pellets, and the multi-fuel stove can work for
burning both corn pellets and wood pellets.
4. Storage
Dampness will affect the performance of wood pellets, so they must be
transported and stored in dry condition. Exposing bagged wood pellets
outdoor or in an indoor damp environment must be avoided.
Storing corn pellets is problematic, and large areas like spare garage, or
silo are preferred. Corn pellet also need the avoidance of dampness, at the
same time, they have to be stored in an airtight plastic or metal container
to prevent rats, insects and other rodents for the corn property of being
food.

Burn Corn Pellets by Corn Stove or Multi-fuel Pellet Stove
Corn stove is a type of pellet stove that is specially designed to burn corn

pellets, and it is similar to a wood pellet stove. But the chief difference
between a wood pellet stove and a corn stove is the corn pellet stove has
an addition of the active ash removal system and the metal stirring rod
within the firepot. And the metal stirring rod is to churn the firepot as it
rotates; the ash removal system consists of augers at the bottom of the
firepot that discharge the ash and clinkers. During the burning of corn
pellets, the sugar content within maize will cause the ashes to stick
together, forming a hard mass, which means the corn stove has to be
cleaned more often, and the metal stirring rod can break apart these
masses, causing a much more consistent burn. Some special stoves are
designed to automatically clear the clinkers, while others must be cleared
regularly by hands. Corn pellet stove do not require a traditional chimney
system, instead require an exhaust vent. Some vents can be set on the side
of the building.

In the mean time, there is also another option of multi-fuel pellet stoves
which can work for various fuels, including wood, corn, cherry pits, etc.,
to burn the maize pellets.

Growing Popularity of Burning Corn Pellets
America is the leading country planting and producing corn, and there are
long term experiences with burning corn in the US, where they worked
intensively already in the 1970s to develop the technology for burning
maize.

Nowadays, to improve the utilization rate of fuel and reduce polluting
environment, processing the biomass materials into pellet is a popular
way to meet the requirement, and corn pellet is common in the US, so
America can be a large potential market for corn pellet production and
application.

In 2005, there were an estimated 65,000 corn pellet stoves in the US. A
year later, it was more than double to 150,000 and by 2007, it was
expected to reach 350, 000. This is because corn is among the cheapest
fuel resources. Wood pellets are in short supply and their prices have
more than doubled. However, the rapid rise in demand for corn stoves
means they are hard to come by.

Besides America, China, Brazil, Mexico, Argentina, India, France,
Indonesia, Italy and Canada, etc. are the other countries having large
capacity of maize production, which have the possibility to manufacture
corn pellets, or be the suppliers of corn as the raw materials for making
corn pellets.
