Title: Innovations of Muh-Cheng M Wu
Introduction
Muh-Cheng M Wu is a notable inventor based in Pittsburgh, PA, recognized for his contributions to the field of aggregate production from coal combustion by-products. With a total of 2 patents, his work focuses on innovative methods that enhance the utility of industrial by-products.
Latest Patents
One of his latest patents is a "Method for making manufactured aggregates from coal combustion." This method involves producing aggregates from coal combustion by-products that contain sulfur. The process includes mixing recycle fines with calcium hydroxide, an aluminum-containing material, and water to create a feed mix. This feed mix is agglomerated into a product that is then combined with curing fines containing calcium oxide. The blended mix is cured using moisture, which hydrates the calcium oxide, converting it into calcium hydroxide and generating the necessary heat for curing. The resulting aggregate products are separated from dry fines, which are recycled back into the mixing step for further use.
Another significant patent is the "Process for making high-strength synthetic aggregates." This process entails hydrating calcium oxide from coal combustion ash to convert a high percentage of calcium oxide into calcium hydroxide before forming and curing the aggregates in high humidity. The hydration moisture is carefully monitored to achieve the desired set point, ensuring the production of high-strength aggregates from calcium hydroxide-containing FGD ashes generated from various processes.
