GE’s Jenbacher gas engines include gas-fueled reciprocating engines,
packaged generator sets, and cogeneration units for power generation.
GE’s Jenbacher gas engines range in power from 0.25 to 9.5 MW, and run
on either natural gas or a variety of other gases (e.g., biogas, landfill gas,
coal mine gas, sewage gas, combustible industrial waste gases).
A broad range of commercial, industrial, and municipal customers use Jenbacher products for on-site generation of power, heat, and cooling. Additionally a full
range of services is offered. Patented combustion systems, engine controls, and monitoring enable Jenbacher power generation plants to meet stringent emission
standards while offering high levels of efficiency, durability, and reliability. GE’s Jenbacher product team has its main production facility and more than 1,400 of its
2,000 worldwide employees located in Jenbach, Austria.

GE’s Jenbacher gas engines team focuses on technical excellence in wasteheat-to-electricity generation in small-scale applications. Our Heat Recovery
Solutions team developed an innovative 125 KW heat recovery generator,
which recovers the waste heat from various types of engines and biomass
boilers and uses it as fuel to produce electricity with no additional environmental emissions.

Power generation from landfill gas
with Jenbacher gas engines.

landfill gas as an energy source
Landfill gas is created during the decomposition of organic substances in Municipal Solid Waste (MSW). Depending on the
landfill design and its management, as well as waste composition, compaction, moisture and several other factors, thousands
of landfills are available worldwide to collect and utilize this valuable energy source for power generation.
landfill gas collection
For a landfill restoration that prevents greenhouse gas from
migrating into the atmosphere while avoiding offensive smells and
smouldering fires, the gas must be continuously extracted under
controlled conditions. Perforated tubes are drilled into the landfill
body and interconnected by a pipe work system. Using a blower,
the gas is sucked from the landfill. A well-designed gas collection
system will flexibly capture the gas from various spots and handle
high temperatures, leachate, condensates and air content - thus
ensuring a cost-efficient collection as well as stable gas quality.
Several engineering companies specialize in this field and offer their
services on a worldwide basis.
amount and composition of landfill gas
Municipal waste contains 330 to 550 pounds (150 to 250 kg) of
organic carbon per ton, which microorganisms convert into landfill
gas through an anaerobic process. The gas formation is influenced
by a number of factors such as waste composition, landfill storage
height and density, air temperature, atmospheric pressure and
precipitation levels. Decomposition starts one to two years after
the waste is deposited in the landfill and lasts 15 to 25 years. The
continuously decreasing gas volume can be compensated by the
disposal of additional waste during this period.
With a calorific value of 340 to 530 BTU/square feet (3,5 to
5,5 kWh m3N), landfill gas constitutes a high-value fuel for gas
engines that can be effectively used for power generation:
Methane (CH4) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 35% – 55% by volume
(methane has 21 times the global warming potential of CO2)
Carbon dioxide (CO2) . . . . . . . . . . . . . . . . . . . . . . . . . . . . 30% – 44% by volume
Nitrogen from air (N2) . . . . . . . . . . . . . . . . . . . . . . . . . . . 5% – 25% by volume
Oxygen from air (O2) . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0% – 6% by volume
Water vapour (H2O) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . saturated
Consequently, 1 million tons of MSW generate about 60 to 90 million
square feet (1.7 to 2.5 million m3) of collectable methane, enough to
fuel a gas engine capacity of 850 to 1,250 kW pr oducing 6,500 to
10,000 MWh electricity per year. That roughly corresponds to the
average power demand of 1,500 to 2,200 EU households.
and specially designed engine parts resist the impurities that usually
appear in this type of fuel.
Before the landfill gas can be fed into the gas engines, it needs to
be dried and compressed. Severe contaminants such as siloxanes
should be removed if exceeding a certain level. Not only will
these measures considerably increase the availability, but they
also will reduce the O&M engine costs. Since landfills are usually
located near big cities, emission standards are becoming more
and more rigid in many countries. To comply with those standards,
the whole system must be managed, beginning with the fuel
gas conditioning up to the installation of an exhaust treatment
device, if needed.
GE's Jenbacher gas engines are committed to not only supplying
the gas engines, but also offering auxiliary equipment and giving
support for an integrated solution - from the gas flange to the grid
connection.

our competence
With more than 25 years of experience in the combustion of landfill
gas - and more than 1,500 landfill gas systems with a total electricity output of about 1,500 MW delivered throughout the world - the
Jenbacher product team offers an unparalleled breadth of expertise, references and solutions.
These plants generate about 12 million MW-hours of electricity a
year – enough to supply more than 3 million EU homes. In addition, by capturing landfill gas instead of emitting it directly into the
atmosphere and using it for power generation in place of fossil
fuels, these engines can reduce greenhouse gas emissions by about
48 million tons CO2 equivalent each year. This amount of greenhouse gas emission savings equals the annual emissions related to
nearly 27 million EU passenger cars.
Qualified as ecomagination products by an independent agency,
Jenbacher landfill gas engines provide our customers with a costeffective, high-output means of generating power while substantially and measurably reducing emissions. Ecomagination is a GE
commitment (www.ge.com/ecomagination) to use and develop new
technologies to help customers around the world meet escalating
environmental challenges.
