FOR SALE: USED STEAM TURBINE & GAS TURBINE

FOR SALE STEAM & GAS TURBINE 02

Recently DDM became owner of the Hem-weg 7 power plant which is out of operation since December 2012.

Since that moment precautions are taken to ensure that the equipment of the power plant stays in its perfect condition.

The plant consists of one direct fired boiler installation, heavy fuel oil (HFO) and gas, and a steam turbine in combination with a gas turbine.

The gas turbine, the boiler and steam turbine can be operated separately and/or in combination.

The boiler and steam turbine were com-missioned in 1978. In 1988 the GT13E gas turbine has been taken into operation.

The new EV burner unit has been installed in 1996.

A new and modern digital control system is installed several years ago.

The steamturbine consits of a high pressure, medium pressure and two low pressure turbines.

CharacteristicsPower output depends on air and cooling water temperature. Therefore temperature curves are set for plan-ning purposes.

PropertiesThe calling time is the time needed for a Powerplant to come standby and is downtime dependable.The start time is the time needed to come from standby to parallel and is also downtime dependable.

Control Restrictions (Regelrestricties or Ramping)Per specified call time control restrictions are given. Once a unit delivers power, for all start types maximum control restrictions apply. The maximum control restrictions are noted points in time and net power output. The maximum control restrictions are valid if the unit is ramped up to its maximum. In the ranges between the dictated points, more points can be described.

Shutdown RestrictionsShutdown a unit regularly can be done in respect to two aims, i.e. being available for production as fast as possible or being available for maintenance as fast as possible. We distinguish therefor two types of shut-down: Shutdown Warm, Shutdown Cold

The stop procedures describe from a specific amount of power output which special restrictions occur. The format equals the format of the control restrictions.
