Background Adrian Alford1, Philip Nichol1 and Ben Frisby2 1Corac Energy Technologies, Stirling Road, Slough SL1 4ST 2Spirax Sarco Ltd, Runnings Road, Cheltenham, GL51 9NQ E-Mail: Philip.Nichol@corac-cet.co.uk Abstract. The efficient use of energy is paramount in every kind of business today. Steam is a widely used energy source. In many situations steam is generated at high pressures and then reduced in pressure through control valves before reaching point of use. An opportunity was identified to convert some of the energy at the point of pressure reduction into electricity. This can be accomplished using steam turbines driving alternators on large scale systems. To take advantage of a market identified for small scale systems, a microturbine generator was designed based on a small high speed turbo machine. This gave rise to a number of challenges which are described with the solutions adopted. The challenges included aerodynamic design of high efficiency impellers, sealing of a high speed shaft, thrust control and material selection to avoid steam erosion. The machine was packaged with a sophisticated control system to allow connection to the electricity grid. Some of the challenges in packaging the machine are also described. The Spirax Sarco TurboPower has now concluded performance and initial endurance tests which are described with a summary of the results. 1.1 Expertise of partners Spirax-Sarco Limited has over 70 years of experience in research and innovation in most aspects of saturated steam generation and transmission. The company provides expert advice to UK government and other organizations to formulate strategies and standards around steam systems, boiler operations and sterilization. Spirax Sarco offers an extensive portfolio of products and services, creating solutions for steam-using organisations worldwide. Corac Energy Technologies have considerable experience in the design and development of innovative turbo-machinery for specialist applications in the oil and gas and industrial markets. The two companies applied their combined expertise to this development project 1.2 Market need & drivers Energy costs are of significant concern to industry worldwide, and play a significant part in the viability and profitability of many processes.
