A by-product from burning pulverized coal in electric power generating plants, fly ash can contain substantial levels of mercury which can negatively impact human health and the environment. Responding to the threat of mercury exposure, the EPA has established tough standards for the power industry to meet. Vulcan® Systems Thermal Desorption Units remove mercury from fly ash, making the end product reusable for concrete production. Through this process, power plants are able to create a new revenue stream through the sale of clean fly ash, eliminate expensive disposal costs, and protect the environment. Besides solving the disposal problem, adding fly ash to concrete improves the quality of the concrete. As a replacement for Portand Cement, the use of fly ash saves on material expenses, decreases permeability, and prevents expansion, thermal cracking, and efflorescence. It also increases working time, and makes pumping and finishing much easier.
