Demonstration Test Plant

A main flow diagram of a 200 kW multi-fuel type PAFC power plant which was used for demonstration tests is shown in Fig. 1. The plant was made by partially reconstructing a200kW PAFC power plant for pipeline town gas. An LPG supply unit and fuel switching equipment were added to the plant. Start-up and power-generation control programs for LPG and a fuel-switching program were added to a controller in the plant, too. The quantity of the pipeline town gas, LPG, and steam supply is automatically controlled by regulating the open rates of the control valves for pipeline town gas and LPG, and the ejector for steam. When the plant generates power using either pipeline town gas or LPG, both
