The Power of Gas Producer

For more than seventy years from its onset, coal gas making process for illumination remains largely unchanged as a laborous, less efficient, and time-consuming batch operation. The clarification of heat and caloric and their nature demonstrated convincingly by James Joule opened up the door for chemistry to leap forward that had led to not only a series of scientific discovery but also several revolutionary development of industrial processes. What is about to evolve below is a story about how heat is used to establish the Open Hearth Process to de-bottleneck the steel making process, one of the most vital product at the time, and how the integration of a gas producer and a regenerative furnace eventually starts to change the traditional coal gas making process.
