Turbo Phase overview

1
Turbophase utilizes a 2MW reciprocating gas (or diesel) engine to drive an intercooled
compressor and uses the waste heat from the engine to heat the air up
Turbophase process is simple and efficient
• Turbophase =Intercooled
Compressor
• Gas turbines = Axial
Compressor
The Intercooled process is 34%
more efficient than the axial
process at generating hot

TurboPHASE Overview
Modules are factory tested prior to shipping
Certificate of Compliance:
• Air flow generated
• Air temperature
• Air pressure
• Fuel consumption
• Sound level
• Vibrations
• Auxiliary load
• Safety functions
Turbophase modules hit the ground running with no surprises

5
TurboPHASE Overview
Multiple modules can be hooked up to one or more gas turbines
Modularity provides
• One size fits all, just vary the
number of modules
• Low production cost
• Rental/Leasing available
• Smooth power ramping: 0->Full
Modularity provides flexibility and low cost

TurboPHASE Overview
Designed for simple integration
Interconnects
• Fuel: NG @ 5psi
• Water: zero consumption, 600gpm flow in and out
• Electricity: 480V, 35kW per module
• Foundation: floating slab or concrete foundation, subject to local civil
codes
• Controls: one fiber or Ethernet cable
• Injection and Exhaust air: one connection to existing GT locations
• Recip engines meet emissions reqt’s of NSPS 40 CFR 60, Subpart JJJJ;
eliminates need for initial performance test at site
• GT Concentration remains unchanged out of stack. TPM exhaust routed to
HRSG and existing SCR

TurboPHASE Overview
Designed for safe & proper GT operations
Item Mitigation
Air Quality Air is filtered with Nema 4, Merv 13 filters, IGT industry standard
Foreign Object Damage (FOD) 50 Micron strainer located in Injection Air header prevents FOD reaching the
gas turbine
Combustion Stability Increasing air flow with TurboPHASE drives the combustion system towards its
ISO day design condition, improves combustion dynamics and increasing
velocities
Control Settings No control settings are changed in the gas turbine. The current logic manages
changes in mass flow. The TPM controls are seamlessly integrated into the plant
DCS and AGC. Control signal is 1-way.
Maintenance Impact No maintenance impact to any parts (CI, HGP) due to increased mass flow.
Trip Settings The injection air is isolated from the gas turbine with two control valves that fail
closed or close on GT / TPM trip signal. The vent valve normal operation is
open to atmosphere.
Start Permissives Ready to Start, Ready to Inject logic set to prevent unwanted operation

Turbophase air cooler option eliminates need to tie into plant cooling water
Only water required is on initial fill of the system

TurboPHASE Installation in Middle East
Turbophase simply adds the missing air and power back to the gas turbine that is
naturally missing due to high ambient temperatures and altitude
Site Conditions:
• 45-55C (122F)
ambient temp
• 200m altitude
GT output 122MW @50C
• 27% below ISO rating
• Missing 27% air and
output

Every time units are turned on/off, incremental MW and fuel was measured (every day)
1. Net Power of GT existing customer MW meter
2. Auxiliary load validated by customer (35kw per module, 50 kW pumps, 75 kW fans,
185 total for the two modules)
3. GT Fuel existing customer meter
4. TPM Fuel new meter
5. Net Power = 1-2
6. Net Plant heat rate = (3+4)/(1-2)
Turbophase demonstrated power output, efficiency, part load, and life extension
Turbophase is an extremely flexible system and very simple to measure the performance
• Demonstrated Base and part load fuel efficiency with air injection
• Demonstrated Base Load output with parts life extension 24,000 hrs to 32,000 hrs

TurboPHASE System controls integrated to DCS
• No changes to GT Controller, Gas turbine controls are completely unaffected
• DCS provides Output demand to TPM
• TPM converts output demand to pressure and flow, internal PLC
• Permissives and trip functions aligned with GT operations

19
Incremental power is proportional and instantaneous to air injection rate
• Several Failure (TPM Trip) scenarios were tested
• Air Injection can be used for high speed regulation

Total Incremental Power (MW) 6.81 7.27 7.26 7.18 7.24 (+6%)
Incremental Heat rate (BTU/kWh) 8738 8820 8748 8792 8787

21
Rapid trip test successful
• Typical GT Controller updated in ~10 milliseconds
• Valve response in ~100 milliseconds
• GT responds to TPM Trip (loss of air) as planned in 2 seconds
• Combustion Process more stable (rich event) with TPM trip

22
GT Compressor Limits protected by GT controller
• Significant compressor stall margin exists at base load
• Compressor Stall Parameter limits defined in Mark Controller
• Compressor stall Margin, generator limit and shaft limit would allow 25% air injection, 50%
power increase on an 80F to 100F day
