GE Jenbacher Series 6

The Series 6 engine offers excellent reliability in the 1.7 to 3 MW power range.

High capacity rate and low installation costs are an asset of this engine which has a speed of 1,500 RPM.

Maximum efficiency with low emissions are achieved by the design of its pre-combustion chamber.

The first major service is at 60,000 hours due to the excellent design of this engine. Excellent spare parts offer quality and long life

whether your engine is running on natural, coke, landfill, mine or wood gas.

Complete functional CHP power plant  16.000 KWe, 50/60Hz, 400/480 10/11.000 volt, natural gas, consisting of 8 unused Jenbacher generator sets type JMS 616 GS-NL , year 2001, unused -0 hours - complete with 3 buildings.

Generator set JMS616 GS-NL

Engine and generator housing are bolted together by a special mounting flange and placed with vibration absorbers on a common base frame.

The rotating shafts are coupled by means of a flexible coupling.

The rest vibrations are so limited that the common base frame can be placed directly on the

concrete foundation. No special foundation constructions are necessary.

Heat recovery built in !

Each engine has its own heat recovery system.

Heat is recovered from lube oil, jacket water, charged air-gas mixture and exhaust gases.

The lube oil cooler, jacket water cooler and charge air cooler are direct mounted on the base frame.

The exhaust cooler is executed as a separate freestanding unit.

All coolers are made of stainless steel and executed as compact plate heat exchanger, except for exhaust cooler which is executed as stainless steel shell and tube boiler.

If steam is required the exhaust gas cooler must be replaced by an exhaust gas steam boiler,

jacket water and lube oil can be used for heating the condensate and feed water.

In case heat recovery is not required, exhaust gases shall flow directly to the stack and lube oil, jacket water etc. must be cooled by an air fin bank.

Lube oil system

Each engine has a mechanical driven lube oil pump and an electrical driven pre lubrication pump.

The oil level in the crankcase will be automatically controlled by a level switch and electric valve. The oil will flow to the crankcase by gravity. For quick oil exchange two separate electric driven lube oil pumps are installed, one for fresh oil and one for used oil.

Two storage tanks will be supplied, one for fresh oil and one for used oil, tanks are equipped with level indicators and level switches.

Natural gas manifold

Each engine has its own gas manifold, equipped with one manual shutoff valve, two electric

shutoff valves, gas filters, pressure controllers, pressure switches (min./ max. protection) and

pressure indicators (manometers)

A flexible stainless steel hose will connect engine with the gas manifold.

Starting system

Engine is started with an electric start motor. Each unit has its own starting batteries and

automatic battery charger 220/24Volt.

Control panel

Each unit has its own control panel with all controls and protection devices.

A major part of the control is the Jenbacher motor management system called DIA.NE. This system comprises powerful central industrial controls that handle master control and feedback control for the engine-plant, as well as visualization. A link with central process control is provided to meet the specific requirements of customers, via standardized industry busses or using direct signal lines.

The particular focus of the DIA.NE design lies in combining powerful and flexible open- and

closed-loop control electronics with a user-friendly operating concept.

The visual display uses a colour graphics display screen, providing clear and comprehensible

presentation of information and measured values.

LEANOX system

Each engine is executed with the so called Leanox system.

This lean mixture combustion control is developed and patented by Jenbacher. It ensures

the correct air/gas ratio under all operational circumstances in order to simultaneously

achieve the lowest exhaust gas emission rates and stable engine operation.

Knock control system

Each engine has its own knock control system.

The resulting specific firing point, output and gas/air mixture temperature control protects the engine from inadmissible loads, resulting in increased reliability and availability.

Exhaust gas silencer

Each engine has its own silencer, stainless steel with condensate relief connection and

flexible compensators. Sound pressure 60dB(A) at 10 meter.
