CHP Overview

CHP is not a new technology

�Used in Thomas Edison’s first electric generating plant in 1891

�Used in industrial, institution, and municipal applications today

Governments see the benefit for both fuel savings and emissions

�US Department of Energy has a goal to double CHP use by 2010

�European Commission has set similar targets

Environmental Benefit

Reduce demand on national electric grid

�Power often produced by high emitting coal-fired plants

�Reduction in CO2, NOx, and Particulates

Higher efficiency means conservation of natural resources

NOx Control Technologies

Miller Cycle Engine� The Miller cycle engine is an example of reduced NOx emissions

due to Charge Air Cooling.

� As shown in figure below, intake valve remains open for an additional 30 degrees thus reducing the effective engine displacement.

� ‘Back flow’ due to late intake valve open is compensated by density of charge.

� Reduced combustion chamber temperature at TDC results in lower NOx.

� Reduced engine size also provides substantial reduction in frictional losses, thus increasing fuel efficiency

Page 20: Amazon Simple Storage Service (S3) - Climate Change and the …s3.amazonaws.com/ebcne-web-content/fileadmin/pres/... · 2014-06-16 · Cummins Announces Approval of B20 Biodiesel

20

Exhaust Gas Recirculation (EGR)� Displacing an engine’s intake air with inert material can

reduce NOx emission.

• EGR is a form of intake air dilution.

Selective Catalytic Reduction (SCR) by Urea:• Typically uses nitrogen containing ammonia or urea as

reducing agents to achieve high NOx control (up to 90%+).

21

Particulate Matter Control Technologies

Diesel Oxidation Catalyst (DOC):• PM emissions composed of carbonaceous particles, soluble organic

fractions (SOF) and sulphates among other things.• Oxidation catalyst reduce SOF but have little impact on other components.• Typically reduce PM by 20-30%.

Diesel Particulate Filter (DPF):• Filters, also called traps, filter PM from exhaust stream with

subsequent oxidation of captured PM.• Ceramic wall-flow monoliths are used as filter material in most cases.

Diesel Fuels:• Diesel fuel properties impact diesel exhaust emissions.• Many after treatment technologies are sensitive to sulphur in the fuel.

Biodiesel offers the environmental benefit of renewable energy

Can also help reduce dependency on imported oil

Provides overall emissions advantage with reduced PM, HC, CO and CO2 (production/use cycle basis)

Cummins is working with industry groups to standardize fuel specifications

Cummins supports the responsible production and use of biodiesel

We will use biodiesel in our operations where appropriate and produce products that are capable of operating with biodiesel

Biodiesel must not harm the availability or economics of the global food supply

Rain forests and water are resources that must be sustained

B20 Approval

Cummins Announces Approval of B20 Biodiesel Blends – March 21, 2007 (everytime.cummins.com)

Approval limited to targeted engines - Additional approvals under evaluation/testing

Requirements specified in Cummins Service Bulletin 3379001Vehicle/equipment OEM’s have their own specific requirements

B20 approved engines:

� On-Highway: ISX, ISM, ISL, ISC and ISB engines certified to EPA '02 and later emissions standards, and ISL, ISC and ISB engines certified to Euro III

� Off-Highway: QSX, QSM, QSL, QSC, QSB6.7 and QSB4.5 engines certified to Tier 3/Stage IIIA, QSM Marine and QSM G-Drive.

� All future products will be compatible with biodiesel B20

BQ-9000

For North American markets, Cummins Inc. requires that the biodiesel fuel blend be purchased from a BQ-9000 Certified Marketer.

The B100 biodiesel fuel used in the blend must be sourced from a BQ-9000 Accredited Producer.

Certified Marketers and Producers can be found at the following website: http://www.bq-9000.org.

For areas outside of North America, the local Cummins representative must be consulted for applicable fuel quality standards.

Page 28: Amazon Simple Storage Service (S3) - Climate Change and the …s3.amazonaws.com/ebcne-web-content/fileadmin/pres/... · 2014-06-16 · Cummins Announces Approval of B20 Biodiesel

28

Biodiesel Fuel Storage

Use biodiesel fuel within six months of its manufacture. Biodiesel has poor oxidation stability, which can result in long term storage problems. For this reason, Cummins Inc. does not recommend using biodiesel for low use applications, such as standby power or seasonal applications. Consult your fuel supplier for oxidation stability additives.

The poor oxidation stability qualities of biodiesel can accelerate fuel oxidation in the fuel system, especially at increased ambient temperatures.

29

Fuel Water Separation

Biodiesel has a natural affinity to water, and water acceleratesmicrobial growth. Storage tanks must be equipped with a fuel water separator to make sure that water is stripped out before entering the vehicle tank.

Make sure that the vehicle and storage tanks are kept full to reduce the potential for condensation accumulating in the fuel tank.

Due to the solvent nature of biodiesel, and the potential for “cleaning” of the vehicle fuel tank and lines, new fuel filters must be installed when switching to biodiesel on used engines. Fuel filters will need to be replaced at half the standard interval for the next two fuel filter changes.

Page 30: Amazon Simple Storage Service (S3) - Climate Change and the …s3.amazonaws.com/ebcne-web-content/fileadmin/pres/... · 2014-06-16 · Cummins Announces Approval of B20 Biodiesel

30

Biodiesel Fuel Storage (cont.)

If biodiesel is used for seasonal applications, the engine system must be purged before storage by running the engine on pure diesel fuel for a minimum of 30 minutes.

Care must also be taken when storing biodiesel in bulk storage tanks. All storage and handling systems must

be properly cleaned and maintained. Steps must be taken to minimize moisture and microbial growth in storage tanks. Consult your fuel supplier for assistance in storing and handling biodiesel.

All Cummins products are approved for use with B5.

Cummins has completed the necessary testing and evaluations and developed guidance to ensure that customers can reliably operate selected engines with confidence using B20 fuel.

Only B100 biodiesel that meets ASTM 6751 or EN14214 and the EMA B20 blend test specification can be used. There are no specifications to define blends above B20. Recent national audit shows quality is still a big issue in the industry.

Cummins is currently focused on supporting the B20 release and continued validation efforts to approve additional engines.

Critical needs are to improve B100 standards, create B20 standards and improve biodiesel quality.
