Process Chemistry |

The
system: Biomass Gasifier is essentially a chemical
reactor where various complex physical and chemical
processes take place. Biomass gets dried u, heated,
pyrolysed, partially oxidized and reduced in this
reactor as it flows through it. Four distinct
processes take place in a gasifier: Drying of
the fuel, pyrolysis, combustion and reduction.
Although there is a considerable overlap, each
process can be considered to be a occupying a
separate zone in which fundamentally different
chemical and thermal reaction take place.
The fuel must pass through all of these zones
to be completely converted. The essential
characteristic of the down - draught design being
used in
our “BG-Ank”(The Global brand name in Biomass
Gasifiers) is that it is designed so that the
tars gives off in the pyrolysis zone are drawn
through the combustion zone, where they will be
broken down or burned. When this happens,
the energy they contain is usefully recovered
and the mixture of gases in the exit stream is
relatively clean. |

What
are the normal acceptable FEEDSTOCK |
|
In
addition to almost all types of wood waste and
fuel wood / firewood etc.,
“BG-ANK” gasifier can operate on the following
feedstocks: |
 |
Branches
and Twigs |
|
Maize
cobs |
|
Weeds
like lantana camara |
|
Appropriate
briquettes of various agricultural residues |
|
Stalks
of Cotton, pulses etc |
|
Coconut
Shells |
|
Briquettes
of tamarind husk |
|
Certain
industrial wastes of paper mills, plywood industry
etc |
|
RICE
HUSK, SAW - DUST AND FINES ARE ALSO USED NOW-A-DAYS |
| |
| With
constant research and development, the range of
acceptable feedstocks for “BG-Ank” gasifier keeps
on expanding. |
