Engineers Develop Laser Solution To Power Plants Slowed By Slagging

The system relies on laser-induced breakdown spectroscopy to provide instant analysis of the elemental composition of coal as it is being burned. LIBS was developed by engineers at Lehigh University in Bethlehem, Pa., and at the Energy Research Company in Staten Island, N.Y. Slagging and related problems cost coal-fired power plants an estimated $2.4 billion each year.
