These units now sold, but more gas engines here:
Introduction: A highly technically skilled and experienced company who routinely install new, or dismantle and re-locate large engine driven power stations arond the world – typically say from China to Nigeria (20 MW diesel0, or from Spain to Russia (5 MW gas) or from Finchley North London, to Wessex Water Poole (Jenbacher 0.7 MW biogas). This one, a 7 MW station, comprising 2 x 3.5MW engines, (that’s about 3 High Speed Train power cars) is lying in store in the UK, fully refurbished. There is probably a not inconsiderable commission to anyone finding a home Price tag around $2 million dollars.

1. PROJECT SCOPE
The supply, construction and commissioning of a 7 MWe power station first commissioned in September 2000 but mothballed in November 2001. Now available for immediate relocation – 50hz utiltiy.
Basic scope of work is to dismantle in Europe, pack, ship, re-erect and commission a 7MWe gas fuelled power station. A Turnkey price can be provided subject to site survey, civil and electrical infractructure requirements.
The available equipment consists of two DEUTZ TBG632V16 gensets powered by natural gas and all the necessary ancillary equipment including heat recovery and transfer plant, controls, switchgear, power cables to the 6.6kV board and small wiring within the station.
A natural gas measurement and Regulation System (MRS) filters and reduces the gas pressure from the network pressure.

Each engine drives a 6 pole 4,600 kVA 6.6kV 50Hz alternator.
The alternators are direct coupled to a 5 PANEL 6.6 kV SCHNEIDER switchboard.
Medium voltage and 400 volt Power and control cabling within the station is to europran regulations.
An Auxiliary Services transformer 6.6/0.4 kV, 400kVA, 50 Hz feeds an auxiliary Services Panel for
– Cooling radiators
– Pumps and fans
– Process Control Panel
– Motor Control Panel
– Bridge Crane
– Air coolers
The motor exhaust gases are directed to a mixed multitubular boiler that produces 7 t/h of saturated steam at 6.5 bar with the heat of the exhaust gases, and this boiler also has a conventional natural gas burner that produces 3.1 t/h. The conventional burner would go into operation in the following cases:
– To supplement the steam demand due to demand higher than 7,179 kg/h.
– To handle the full steam demand (up to the maximum of 3,600 kg/h) in the case of a malfunction or prolonged motor stoppage, which would require steam production independent from cogeneration.
The following table provides the information on the multitubular generator:
Maximum steam flow with only motor gases 7.1 t/h
Steam flow with only conventional burner 3.6 t/h
Maximum steam flow with motor gases and burner 10.7 t/h
Registered pressure 11 bar
Normal operating pressure 6.5 bar
Steam quality Saturated dry
Motor gas recovery flow 38,268 kg/h
Motor gas temperature 535ºC
Maximum burner power 3,950 kW
Feed water temperature 80ºC
Eco output temperature with motor exhaust gases 117ºC
Output temperature with just the burner 225ºC
Output of just gases 78.5%
Output with just burner 88%
Hot water The heat energy of the high and low temperature cooling circuits of the motors was also used to produce 40m3/h of water at 60ºC, required in the cellulose casing manufacturing process.
The total thermal balance of the cogeneration plant was as follows:
– Steam production with exhaust gases at 6.5 bar: 7 t/h
– Steam production with exhaust gases with burner: 3.6 t/h
– Hot water production (15ºC-60ºC): 40m3.
– Hot water production for boiler (40ºC/80ºC): 7.5 t/h
The heat recovered in the cogeneration is:
– Heat recovered exhaust gases: 4,936 kW
– Heat recovered cooling water:
– To produce hot water: 2,093 kW
– To heat boiler intake water: 349 kW
– Total heat recovered: 7,278 kW
Total annual Energy Balance:
– Hours of operation per motor: 8,059 h/year
– Electrical power: 2 x 3,535=7,070 kW
– Electricity produced: 56,977,130 kWh/year
– Fuel consumption: 2 x 8,898 =17,796 kW
– Steam produced: 56,413 t/year
– Hot water at 60ºC: 322,360 m3/year
– Heat recovered: 58,653,402 kWh/year
– Equivalent electrical output: 73%
