Abstract:
1. A gas heating device, comprising: one or more resistive heating elements configured to receive an electrical current from one or more power sources; a mounting structure configured to support said one or more resistive heating elements; one or more static mounting devices coupled to said mounting structure and configured to fixedly couple said one or more resistive heating elements to said mounting structure; and one or more dynamic mounting devices coupled to said mounting structure and configured to automatically compensate for changes in a length of each of said one or more resistive heating elements while substantially reducing slippage between said one or more resistive heating elements and said one or more dynamic mounting devices, wherein said one of said one or more dynamic mounting devices comprises a static structure having a guide post, a helical spring configured to slide over said guide post, and a dynamic structure configured to slidably mate with said guide post and compress said helical spring against said static structure when loaded with said one of said one or more resistive heating elements.
