Burning pulverized coal was hardly a new idea Attempts

Burning pulverized coal was hardly a new idea. Attempts had already been made to burn pulverized coal in locomotives, without success. In 1914 Anderson received permission to conduct experiments on the use of pulverized fuel. Anderson and his team (Dornbrook, W. E. Schubert, and Ray Mistele) concurrently studied the pulverizing process and the efficient burning of coal.
