SUBJECT: NEW SEQUENTIAL GRATES (TM) COMBUSTION SYSTEM
This communication is to announce a new technology for waste
and biomass combustion. This technology was developed to overcome problems
associated with burning difficult combinations of feedstock fuels such
as biomass, solid wastes or agri-residue, for heating or for power generation.
This new system is well suited for utilizing various household and industrial
wastes, biomasses and/or fossil fuels. Any combination of these may be
utilized in this new system for heat or electrical power generation. We
call this new system the Sequential Grates (tm) Combustion System.
Incorporated in the system is an automatic infeed conveyor that feeds a
holding hopper that in turn "batch stokes" solid fuels onto grates
within the combustion unit itself. These fuels are then ignited and dropped
from grate to grate while burning, until completely
converted to ash, which is then removed automatically for processing.
Air emissions abatement is achieved using a novel combination of smoke
re-circulation and other pollution abatement technologies. This innovative
combination of abatement technologies is a more economical and
appropriate control technology for the next generation of combustion systems.
Many innovative advantages are inherent in this completely new system including;
Automatic, co-firing, stoking and de-ashing of any combination of solid,
liquid or gaseous fuels, in a single, dependable and effective system,
with successively starved, neutral and excess air combustion, in a single
combustion chamber, using gravity for dependable and "sequential"
fuels stoking movement;
cleaner burning with lower "upstream" and "downstream"
costs by lowering the upstream fuels pre-conditioning costs and downstream
pollution abatement costs. Can be furnished in any size, or group arranged,
in close proximity, to achieve any desired total input/output, with a high
turndown capacity of up to 90%.
Co-fires any combination of fuels including, whole tires, broken pallets,
coal, gas, oil, municipal solid waste, industrial waste, whole tree material,
lumbering residues, loose or baled agri-byproducts, with low cost pollution
abatement via smoke re-circulation.
