Oil Guns for B&W type straight, front and /or rear fired boilers. |
|
Existing (original) oil guns have a very large (around 40) number of parts. More the number of parts/components less the reliability. Also, with the choice of material (cast brass/ bronze) the guns Head & Tail are prone to cracking during handling, assembly etc and are impossible to repair. These parts are also prone to theft by vandals. Copper clad asbestos washers hitherto used needs replacement each time. They also damage the mating faces of Head & Tail. Large number of spares necessitates carrying and maintaining large cumbersome inventory. Failure is frequent, and so is risk of fire let alone the guns non-availability.
