SYNGAS COGENERATION FROM BIOMASS
Isotech designs and manufactures equipment
that can generate electricity and thermal
energy from simple biomass or waste.
For example the process of transformation
of the wood chips in Syngas starts with
the movement of the charcoal to the
entrance of the combustion chamber of the
reactor. In the combustion chamber is the
gasification process which consists in the
thermal decomposition of biomass, and the
heat necessary to sustain the reaction is
supplied by a partial combustion in
conditions of oxygen deficiency.
The gaseous mixture produced is defined
syngas; all subsequent stages of the
process are needed to ensure that the gas
leaving the plant has the optimal
characteristics in order to be used. The
gas leaving the reactor, at a temperature
of about 650°C, is sent to a heat
exchanger tube bundle type of
self-cleaning gas/water that guarantees a
temperature at the outlet of the gas of
about 100°C, this cooling phase is also
the first stage of dedusting gas: the heat
exchanger is, in fact, equipped with a
system for automatic discharge of the ash.
Subsequently, the cooled syngas is sent to
a bag filter that separates the powders in
suspension in such a way that the Syngas
is suitable for subsequent use.
The syngas product can have various uses.
Plant in Firenzuola owned by FEP (
Firenzuola Energia Pulita ) Isotech has
exploited the Syngas produced from wood
chips to feed three engines from 333
kW/each in such a way as to have an energy
efficiency of slightly less than 1 MW.
Isotech, as well as in the field of
biomass, also specializes in the field of
waste for which designs and manufactures
equipment capable of producing, thanks to
pyrolysis, energy from simple refusal thus
decreasing the amount of waste volume to
very low emissions.
Today, among the new disposal systems to
complex technology, pyrolysis is going to
be the alternative to incineration.
Industry experts have in fact facing a lot
of criticism contesting traditional
incinerators, in addition to the
difficulties of conducting and operating
the possibility that highly polluting
products can be dispersed into the
atmosphere despite the presence of
monumental and costly abatement systems
and flue gas cleaning.
