THE NEW FLY ASH

A BRIEF DESCRIPTION IS GIVEN OF SOME EARLY RESEARCH ACTIVITIES IN DEVELOPMENT OF TECHNIQUES FOR EVALUATING NEW FLY ASHES WHICH ARE BEING PRODUCED IN LIMITED QUANTITIES THROUGHOUT THE WORLD. THESE FLY ASHES ARE OBTAINED FROM BOILERS WHICH ARE UTILIZING INJECTION OF LIMESTONE AND DOLOMITE AND DERIVATIVES OF THESE MATERIALS IN AN EFFORT TO CONTROL THE SULFUR DIOXIDE EMISSION OF THESE BOILERS. THE PAPER DESCRIBES SOME OF THE CHARACTERISTICS OF THESE NEW FLY ASHES AND PRESENTS A DESCRIPTION OF SOME OF THE REACTION PRODUCTS OBTAINED WITH THEM. SUBSTANTIAL DIFFERENCES HAVE BEEN OBSERVED WHEN COMPARING THE NEW MATERIAL WITH OTHER FORMS OF FLY ASH; SOME OF THESE DIFFERENCES ARE FELT TO BE DELETERIOUS AND OTHERS BENEFICIAL WHEN THE NEW FLY ASH IS CONSIDERED FOR CONVENTIONAL USES. NEW APPLICATIONS ARE INDICATED WHICH SHOULD INVOLVE ULTIMATELY THE USE OF SUBSTANTIAL TONNAGES OF SUCH PRODUCTS. MENTION IS ALSO MADE OF EFFORTS TO SYNTHESIZE NEW FLY ASHES UNDER CONDITIONS WHICH WILL PROVIDE QUALITY CONTROLLED PRODUCTS THAT TAKE ADVANTAGE OF THE USEFUL FEATURES OF THE NEW MATERIALS. /AUTHOR/
