A PROTOTYPE STEAM PLANT WITH FLUID BED DESIGNED FOR UNCERTAIN ENERGY CONDITIONS

The future availability, quality, and price of marine bunker fuels are extremely uncertain, and may involve economic risk far beyond the average business risk. The VAP, Very Advance Propulsion, turbine plant has been developed with special consideration to this, aiming at low initial investment and low operational life cycle costs. It offers low fuel consumption, combined with the capability to burn cheap residual fuels, and keeps other fuel options open for the future. This paper describes some innovations, one of which is the application of fluid bed combustion. A five year test program has been completed including operation of a fluidized bed super-heater installed at a Swedish power station during two winter heating seasons. The economic competitiveness of VAP is evaluated using ship life cycle study analysis with both oil and coal as fuel. These evaluations indicate a promising future for the burning of low quality fuel oil and a good prospect for burning coal as the full fluid fed is developed. This technology offers the possiblity to improve the economy of existing ships by rebuilding existing turbine plants. The first VAP engine, which is considered a progression in steam propulsion machinery, is presently under manufacture, with new modularized components and auxiliary systems.
