Jenbacher J920 FleXtra
Whether you’re seeking full power at high efficiency levels or a unit capable of start-up in less than 3 minutes, INNIO’s Jenbacher J920 FleXtra gas engine is a reliable solution for large gas engine power generation plants. This Jenbacher gas engine is designed to support a broad variety of multiple-engine power plant solutions–from remote power supply to combined heat and power (CHP) generation.
The 2-stage turbocharger design of the J920 Flextra allows for no deration at higher altitudes and higher cooling water temperatures-perfect for hot ambient conditions.
MODULAR DESIGN FOR FLEXIBILITY
Modular gas engine design allows for seamless installation with any multiple-engine configuration and offers flexible size options.
Operating a Jenbacher J920 FleXtra at 49.9% electrical efficiency level has the capacity to produce approximately 68 million kWh of electricity.
Jenbacher J920 FleXtra Overview
The newest and largest Jenbacher gas engine has, at 49.9 percent, the highest electrical efficiency of any Jenbacher gas engine.
- A smaller carbon footprint and more energy efficiency.
- High power density at low investment costs.
- Stable power output and reliable efficiency in any ambient condition.
- Quick startup for grid stabilization and easy maintainability.
Did you know?
With more than 90% overall efficiency compared to the separate production of heat and electricity, a J920 FleXtra as a CHP solution is designed to achieve over 130 millions kWh primary energy savings over the course of a year, equivalent to the energy contained in more than 76,000 barrels of oil.
INNIO’s J920 FleXtra Jenbacher engine is designed for durability, simple installation, and maintainability. The GenSet consists of three modules, including a generator, engine, and a turbocharger module, providing a high quality, pre-fabricated, standardized generator-set module. Each module is factory-tested, then shipped separately and assembled onsite, offering reduced installation time. In addition, the modules have highly standardized interfaces that work well with balance of plant (BOP) systems, and ultimately simplify BOP installations and total plant erection time. To maximize plant availability, the J920 FleXtra is optimized for operation and maintainability in the following ways:
The J920 FleXtra power unit concept ensures low maintenance downtime as the complete power unit consisting of cylinder head, water jacket, cylinder liner, piston and con-rod can be exchanged with one assembly.
FAST LOAD AND FAST TRANSIENTS
With the Jenbacher J920, 10.4 MW of electric power can be provided from demand in less than 5 minutes. Newest model-based control technology ensures lowest engine-out emissions during engine start. Together with integrated after-treatment systems and controls overall NOx emissions are minimized over the full load range and even during fast transient operations.
The J920 FleXtra is equipped with a segmented camshaft to support fast maintenance of individual segments through a service window at the top of the crankcase instead of disassembly of the whole camshaft.
