Summary on Grant Application Form
The efficiency of conventional fossil fuelled power stations can be increased by one third, with a consequent 25% reduction in CO2 emission by increasing the high pressure turbine steam inlet temperature to approximately 1200oC. An engineering design research program is proposed for a novel heat exchanger which will produce steam at these temperatures. The design is to incorporate the reversing of the usual mechanical forces on the heat transfer elements in a shell and tube heat exchanger thus allowing the heat exchanger to be made of ceramics which possess superior high temperature properties. Attention in the proposed study is to be focused on (a) the material stabilities of the ceramics used in the tubes of the heat exchanger in the presence of these very high steam temperatures and normal boiler pressures; (b) the provision of novel suitable steam seals on the outside of the tube ends; and (c) the insulation required for thermal protection of the heat exchanger shell. To facilitate seal design and optimisation of the critical dimensions, the systems can include and integral pulverised coal, oil or gas fired burner. This research programme develops the fundamental knowledge needed to design such a heat exchanger, paying attention to what is considered the most critical sections of the overall concept. Thus this research proposal is a design feasibility study.
