Oil firing system for steam locomotives and road engines

---

The burner is the heart of the oil firing system and provides internal atomising of the fuel for maximum efficiency. Burners are available in both ring and single film formats. Each burner is designed with a quick release function to allow rapid changing with a spare burner and routine cleaning at the work bench.

The panplate replaces the ashpan of coal burning boilers. It has air intake tubes custom designed to suit each specific firebox, providing optimum mixing of the gases from the burner. The upper surface has a refractory lining and locates firebricks to protect the boiler plates in the base of the firebox.

The atomising steam is taken from the boiler as saturated steam and a superheater element positioned in the base of the firebox improves the efficiency of the system. The preheater uses a small portion of atomising steam to preheat the fuel supply thus ensuring reliable performance of the burner.

The firedoor is sealed shut to provide crew protection in the event of a wet lighting of the burner. It includes an inspection hatch that can be customised to end user requirements.

 Effective oil firing is facilitated by providing the fireman with the best possible control over the fuel rate, permitting quick and accurate adjustment. Our cam valve provides an intuitive linear opening throughout its range.  

The control valves and pipework are customised to the end user's particular operating requirements. The system is expanded where required by alternative fuels, when fuel tank heating and fuel pipe purging may be required.

The blast pipe stand provides a junction between the cylinder exhausts to prevent back flow, and mitigate other auxiliaries such as brake ejector exhaust from interfering with performance.

The exhaust nozzles are designed circular and machined from solid. The carefully arranged internal angles and overall inclination are a key part of the exhaust system being able to reduce steam consumption by up to 30%.

The chimney diffuser comprises a mixing chamber to maximise draught and a diffuser section for efficient exhaust. This fabrication is mounted within the decorative outer chimney.
