CHP, working on gas

Gas-fired thermal power plant:

The plant will be in continuous operation, supplying electricity and steam to a nearby paper mill. The plant is due to close in April 2013, after which it will be ready for transport. All parts are sold as is with no additional warranties. Transportation is handled by the Buyer.

The plant was built in 1995/96 to replace the boilers. Commissioned in 1997.

Aero-derivative gas turbine "GE LM6000PA".

Power: 42 MW + 7 MW due to the back pressure of the Siemens steam turbine.

Steam productivity: 105 t/h (permanent, short-term - 120 t/h).



Railway turbine exhausts in Nooter Erickson are regeneration steam generator (HRSG), but can also exhaust directly into the atmosphere through the blast stack. This allows the gas turbine to run in standstill mode if the HRSG is not available. The HRSG has additional gas burners which can be done in addition to the gas turbine or can be done without the gas turbine using forced draft (FD) fans to get the known Air. This adds considerable flexibility to the plant.

EQUIPMENT LIST

PERFORMANCE
The CHP plant had a steam delivery availability of around 97% for 2011. They will not have any Maidan outages, planned or unplanned, in 2012 to date. The amount of capacity and scope of production over the old year is available.
