330 MWE POWER PLANT WITH PRESSURIZED FLUIDIZED BED COMBUSTION AND COMBINED CYCLE GAS AND STEAM TURBINE (DESIGN STAGE)

Objective

To design a 330 MWe demonstration power plant with pressurised fluidised bed combustion and combined cycle of gas and steam turbine.

The project involves the complete design of a demonstration power plant, characterized by:
- the combination of a pressurized fluidised bed firing system with a steam generator directly connected, a multi-shaft gas turbine plant and waste heat utilisation systems arranged downstream and integrated into the steam circuit for an electric power output of a total of approximately 330 MW.
- very compact construction by means of a high pressure stage (16 bar) and housing of particularly critical heat-exposed components such as firing system, dust separator etc. . . in a spherical pressure containment.
In addition to the recognized advantages of the fluidised bed firing system, such as:
- considerable improvement of the emission characteristics due to the binding of noxious matter to a large extent - especially of SO2 - by the addition of absorbent directly into the fluidised bed,
- drastically reduced nitrogen oxide and carbon monoxide formation as a result of low combustion temperatures and controlled combustion reaction.
Further considerable advantages can be expected because of the complete plant design conceived in this case compared with conventional technology due to:
- a marked increase in the degree of conversion of primary energy into electrical energy as compared with the usual hard coal fired power station with flue gas desulphurization plants from previously 38,6% to 41,2%, related to plant net power.
- a reduction of the investment costs by 10-15% with a simultaneously considerably reduced space requirement, a fact which is due in particular to the absence of flue gas desulphurization.
- a considerable expansion of the fuel spectrum to include qualities containing large amounts of inerts and noxious matters ( i. e. especially sulphur).
- simple construction for flexible separation of heat.
- significantly more compact design than AFBC.
The total cost of the design phase, represented by this project, amounts to DM 10 million for which a 40% subsidy has been granted.
