Advanced, cost effective limestone wet FGD
- ABB Environmental Systems, Birmingham, AL (United States)
Limestone based wet FGD has been the dominating control technology since the introduction of FGD and hence, has become a mature technology. However, today`s global FGD market demands improvements in terms of capital and operating cost, performance, environmental impact, ease of retrofit and project schedules. In response to market demands, ABB has developed a new generation wet FGD system based on the open spray tower technology. The development of the LS-2 system has progressed methodically Within the ABB community over the past three years. The LS-2 system represent an advanced wet FGD design which offers superior performance at significantly reduced capital and operating costs. It is estimated that the LS-2 system offers between 15 to 30 percent overall cost savings over the latest wet FGD technologies available world-wide. This will make the LS-2 technology cost competitive with fuel switching in most cases. The individual features of the LS-2 system have been extensively tested in various full and pilot-scale facilities. A LS-2 system is presently being constructed at the Niles Generating Station of the Ohio Edison Company. The LS-2 system at Niles is a 130 MWe turnkey, retrofit system which will start up in mid-1995, merely 20 months after initial release of engineering. The system will be connected to both Unit I and Unit 2 boilers and is designed to produce wall-board grade gypsum from low-grade limestones. The gypsum will be sold for use in building materials. Upon completion of a rigorous four month test program, the system will be operated by Ohio Edison. Subsequent testing will focus on long-term reliability, sustained performance, and ease of operability. The LS-2 system will feature cost savings and performance improvements never before demonstrated in wet FGID systems. The cost level of the LS-2 system will make it a clear alternative to fuel switching when applied in a manner similar to the installation at Niles.
