HOUSTON, Texas, September 9, 2003 -- GE Aero Energy, a GE Power Systems business, has been awarded a contract to upgrade gas turbines at Northland Power Income Fund's cogeneration plant in Iroquois Falls, Ontario, Canada.
This upgrade marks the first LM6000 PA to PD conversion in the world.
Under the terms of the contract, GE will supply two new LM6000 PD turbines with Enhanced SPRINT™ (SPRayINTercooling) for Northland's two LM6000 PA turbines as well as provide engineering for the conversion, package hardware to support the DLE (Dry Low Emission) engine and remote diagnostics, training and installation supervision.
The LM6000 PD with SPRINT™ uprate package provides as much as an 18 percent increase in the power output of the LM6000 PA turbine and may improve its heat rate by 5-6 percent under ISO conditions on natural gas fuel. Enhancements in performance are a result of improvements to the low-pressure turbine (LPT) module and the low-pressure compressor (LPC) stator. The SPRINT™ system increases the power output by injecting water into the compressor. An LM6000 PD utilizes a lean premix DLE system to achieve very low emission levels. NOx emissions are estimated to not exceed 25 ppm when using natural gas fuel per GE specifications.
Mapping the LM6000 PD uprate package for optimum performance will be achieved through the use of two Continuous Emissions Monitoring Systems (CEMS) by KVB-Enertec, which was acquired by GE in February 2002.
KVB-Enertec will be providing two CEMS measuring NOx, NO, CO, CO2, O2 and moisture with full data acquisition reporting services. The CEMS will also provide the Provincial Ministry of Environment with regulatory data as well as combustion process monitoring.
Northland will also be upgrading its Mark V control system to the Mark V LM, which provides expanded I/O and 100 Hz computations as required for the DLE engine algorithms. The Mark V LM upgrade also includes a new operator interface using a multi-tasking operating system and GE Fanuc Automation's CIMPLICITYO automation software.
Additionally, the fuel metering system is being upgraded to meet DLE requirements for transient response and flow metering accuracy of 2.5 percent.
GE has had a customer service agreement with Northland since 1996, which has been extended by 100,000 fired hours with this contract. The upgraded turbines will be use for combined-cycle power generation running on natural gas.
