Task 3.12 -- Small power systems. Semi-annual report, January 1--June 30, 1995

PDF Version Also Available for Download.

Description

The programmatic goal in advanced power systems will be to develop small power systems in the range of 20kW to 20 MW in cooperation with commercial vendors. These systems will be designed to incorporate the advanced technical capabilities of the EERC with the latest advancement in vendor-offered hardware and software. Work during this program year has focused on two main technical issues. Pressurized fluid-bed combustion has been identified as one technology applicable to the small user`s market. Work is focused on the development of sorbents for in-bed alkali, sulfur, and chlorine capture to reduce or eliminate problems on backend equipment. ... continued below

Description

The programmatic goal in advanced power systems will be to develop small power systems in the range of 20kW to 20 MW in cooperation with commercial vendors. These systems will be designed to incorporate the advanced technical capabilities of the EERC with the latest advancement in vendor-offered hardware and software. Work during this program year has focused on two main technical issues. Pressurized fluid-bed combustion has been identified as one technology applicable to the small user`s market. Work is focused on the development of sorbents for in-bed alkali, sulfur, and chlorine capture to reduce or eliminate problems on backend equipment. Tar production in the gasification of coal is deleterious to the operation of downstream equipment, including fuel cells, gas turbines, hot-gas filters, and pressure swing adsorption systems, all of which are candidate technologies for use in small power generation systems. Cracking of these tars into smaller hydrocarbons is the second technical issue addressed in this year`s advanced power systems task. In addition to working to solve these technically related problems, existing and developing power systems are being surveyed and a technology option(s) chosen as the focus of further development. The specific objectives of the three tasks are the following: to determine optimum sorbents and their range of effectiveness as in-bed sorbents for alkali, sulfur, and chlorine control during pressurized fluid-bed combustion; to determine the effective operating range of selected sorbents for cracking tars from gasification systems, measure the quality of the resultant gas, and determine the best advanced power systems to utilize this gas; to collected information from vendors, evaluate alternative design concepts, and select a practical and economic design for targeted development in upcoming years.
