The objective of this study is to identify technology improvements which can be implemented to reduce the cost of AFBC industrial steam generation. The approach taken to accomplish this task was to develop ideas by use of a wide variety of sources. Generally speaking, this included engineers, manufacturers, and users. Standard practices were reviewed along with problem areas and potential solutions. Once this was accomplished, an organized brainstorming session using twelve knowledgeable and experienced engineers developed approx.90 ideas for potentially improving AFBC technology. The method used to condense and rank these ideas in the most promising order was a systematic method of analytical evaluation. By a screening process, the list of 90 ideas was reduced to 19, which were then ranked according to a scoring system. The eight top ranked ideas were chosen for further review and evaluation. The conclusions indicate two primary areas of potential economic improvement. The first area appears to be the development of shop assembled/portable packaged FBC boilers and more use of modular design/construction techniques. The other area appears to be in the reduction of air and flue gas pressure losses thus saving fan horsepower. Two other areas of secondary importance are also worth further investigation and development. One idea involves the elimination of onsite fuel and limestone preparation equipment by purchasing preconditioned coal and limestone. This prepared feed material could then be stored and fed using pneumatic delivery vehicles. This approach appears to be very attractive to the smaller unit sizes. The second area of improvement involves the optimization of heat recovery from the ash removal system before disposal.
