a typical municipal solid waste processing plant. Go to downloads

to Capacities page for standard sizing.
The Entech Renewable
Energy System™ is supplied with significant standby capacity
and equipment to ensure high availability and reliability, see
section for more information.
Basic
Process Description is as follows:
The
municipal solid waste typically requires no pretreatment (e.g. no
sorting, no shredding, etc.).
First
Stage: Municipal waste is fed into a Pyrolytic Gasification
Chamber and is heated to the required ignition temperature of approximately
550C (1000F) in a sub-stiochiometric (reduced oxygen) environment,
which maintains the necessary reaction heat required for gasification.
The gasification produces a volatile gas similar to methane that
is referred to as "syngas".

It Works

Chamber - 589kb. When downloading click "Read Only" to
view.
Second
Stage: The syngas is fired like other conventional gases are;
in a large gas burner that is referred to as a Thermal Rector. The
firing of syngas results in a clean high temperature off-gas very
low in pollution concerns, which is environmentally superior to
firing of many conventional fossil fuels.
Third
Stage: As syngas is fired at temperatures of up to 1,200C (2,200F),
the off-gas is a significant heat energy source. Utilisation of
this energy source is accomplished by a heat exchanger (steam or
hot water boiler) which can be used to generate electrical power
or steam or hot water for process use or heating.
Fourth
Stage: To minimise environmental impact (to surpass all standards
required under EU Directives and US-EPA requirements and produce
an off-gas equivalent to say gas fired power stations; the off-gas
is treated by an air quality control system. Emissions consist primarily
of CO2 and water vapor and hazardous constituents are well below
the requirements of EUD/2000/76.

Case Study - Project 1134 - Installed 1998
MSW-BIOMASS
CONVERSION INTO ENERGY
A resort
complex and surrounding community processes around 75 T/dy
of MSW-biomass (municipal waste-biomass). The MSW-biomass
is converted into energy, with the majority of energy being
used to generate hot water for use in the domestic use.
A typical
system
is
based upon MSW-biomass feed into a ram feeder storage hopper
by a small tractor (per LH picture). The MSW-biomass is automatically
charged into the Pyrolytic Gasification Chamber (shown in
the RH picture). The MSW-biomass is converted into a combustible
gas mixture called syngas, which has similarities to methane
gas, including the capacity to burn cleanly. The syngas is
fired in a Thermal Reactor (which is similar to a large gas
burner) For energy utilisation the hot gases are fired into
a fire-tube type hot water boiler. Emissions from the boiler
consist primarily of carbon dioxide and water vapor.

Case Study - Project 1072 Installed 1993
MSW-BIOMASS
CONVERSION INTO ENERGY
A large
university the size of a small city adopted an Entech
Renewable Energy System™
as a model for "eco-friendly" waste management
practices. The system converts around 30 T/dy of municipal
and dried sewage biomass into steam for in-house use. The
process is environmentally superior to combustion of most
conventional fuels, plus is more efficient than many other
forms of recycling.
The
customer's dependence upon landfill for MSW-Biomass (municipal
waste-biomass) disposal and the customer's dependence upon
fossil fuels for energy generation is minimized.
