SECA ProgramSignificant Accomplishments 2002
• System profile
• System physical layout
• Process & Instrumentation Drawing (P&ID)
• System steady state model(s)
• System Transient model(s)
• Cell and Stack Thermal-Mechanical Stress model(s)
• Evolved cell design
• Waterless CPOX reformer
• Control architecture
• Power electronics architecture
A preliminary system profile has been established that defines productcharacteristics in customer and market terms, and translates those needs into thefirst level of product technical requirements.Preliminary design work on the stack(s), manifolds, heat exchangers, reformer,balance-of-plant, and electronics have been combined in a concept layout thatconfirms the feasibility of meeting the target system envelope.A steady state system model has been created to predict operational parameterssuch as air flow, fuel flow, temperatures, and efficiency. This model has beenextensively exercised and yielded key insights used to optimize systemconfiguration.A system transient model has been created and used to model start-up transients.The most encouraging result of the model is the indication that market-driven targetvalues for start time are potentially achievable without exceeding design values fortemperature differentials in the stack.
Working from information developed with the system models, a detailed Process &Instrumentation Drawing has been created to document the configuration, operatingvalues, and instrumentation for the C1 prototype.
Significant work on the Catalytic Partial Oxidation reformer indicates we should beable to operate successfully on either propane or natural gas with excellentefficiency and without carbon deposition.A project website has been developed and incorporated into the CumminsCorporate web page.
