STANLEY STEAM CAR SUPER HEATER6/6/2019 Spring City Steam Works Steam stuff!! Today we bent up 2 super-heaters. We like zigzag over coils but I don't have a tone of reasoning behind it. It's working great in my 735 so why not! There are 2 shown, the more parallel one is for a 10 hp car and the slight more angled open on is for a 20 hp car. Next up on the bender..... Monotube steam generator coils!! Let's go

The zig zag pattern of super heater works better than the circular pattern, first of all because of the round super heater, the total lineal expansion from the heat is excessive. With heat, the circular pattern expands becoming a much larger diameter and in length and it will eventually crack from its flexing. The zig zag pattern breaks up the lineal expansion direction into many short little distances and with less flex, it will last longer. The zig zag super heater also transfers the heat more efficiently to the steam because of the changing directions of the flow pattern. The Stanley motor company eventually went solely with the zig zag pattern because of its positive merits.
