BGP Inc. has examined the co-generation
options that could be provided by operations of the Brookes
technology, in the various opportunities reviewed in Europe,
there is a very good opportunity for the production of electricity
from the machines during the destruction of bovine, other
meat, farine ( meat and bone meal) manures, sewage sludge
and non recyclable municipal waste. The following is an
outline of the potential for the co-generation of electricity
that has been presented by Sentinel Power Corporation and
Combustion & Energy Systems Ltd. of Markham with equipment
reference from Siemens.
The engineering analysis indicates that
it is feasible to insert a steam coil directly into the
tail end of the secondary chamber of each gasification unit.
This is possible because the gasifler is a very clean combustor
and acts very much like a boiler. From the type of waste
being destroyed and using this approach, the steam coil
will be able to produce superheated steam directly.
Based on this concept and to be able to
provide continuous steam flow to the turbine generator,
we would bank 10 gasification modules to one steam manifold,
which would feed one 10 megawatt generator. The modules
would be phased in to operation each day so that they would
not all be cooling down at the same time. It is calculated
that each gasification module is capable of producing enough
steam to generate about 0.9 megawatts or for the 10 modules
9 megawatts. In some of the operations that we are reviewing:
30 or more modules would be required, thus, the electrical
power that can be generated 'when all units are functioning
is approximately 27 megawatts.
There are several advantages to this system
of co-generation of electricity together with the fact that
there is proper destruction of the waste product ( farine,
meat pieces or whole carcasses, sludge, manures etc.).
The advantages of the BGP POWER PACK:
1) Single modules can be shut down for repair without affecting
the electrical flow
2) Different forms of waste can be put into separate modules
without affecting the system
3) Because the electrical generation is separated into 10-megawatt
packages, even if one section is shut down, electricity
can still be sold to the grid
4) In producing the steam as a byproduct from the destruction
of waste material, it is not costing anything to produce
power
5) The overall efficiency of this method is greater than
most, if not all, other solid waste co-generation systems
6) Based on the present assessment of costs, the payback
period for the co-generation components is approximately
36 months.
