This SSI webinar covered the general requirements of an endothermic gas generator and current technology trends on demand based turn down. Details include generic generator design with a deeper dive into the control of the gases used to achieve a proper prepared atmosphere. The endo gas composition is reviewed along with the importance of the gases used for carbon rich and neutral heat treating applications. Control systems and control parameters are explored in detail along with troubleshooting gas composition, control issues and how sensor and control technology are being used to produce only the amount of gas that is needed by the heat treat furnaces. This 60 minute webinar is valuable for anyone that works in heat treating that uses endothermic gas or is considering a prepared atmosphere for their heat treatment processes.
