An unused classic vertical firetube boiler
18th July 2021
A unique opportunity to purchase an unused vertical fire tube boiler built to a classic 1972 Stuart Turner design. This boiler design was offered by Stuart Turner as a suitable match for their ‘Cygnet’ engine, the marine version of the 5A.
It has been constructed to an extremely high standard, with 3/8 inch thick seamless steel tubing for the boiler shell, extensive weld NDT and a heat treatment furnace stress relief of the complete fabrication.
Interlocking mahogany strip cladding is fitted, with brass finishing rings around all bosses.
Key dimensions are 16” inch shell diameter, 30 inch height to top of shell and 63 inch height to top of chimney. Grate diameter is 11 inches and there are 19 solid drawn 11 SWG seamless steel fire tubes of 11/4 inch outside diameter.
Working pressure is 100PSIG, with 200 PSIG initial hydraulic test.
The boiler has just been brought in to the SBAS Inspection Scheme and is offered with a clear ‘No Defects’ report, recent hydraulic test and 14 month certificate from 5 May 2021.
The new safety valve comes with a 6.8 Bar Test Certificate and 12 month guarantee.
This boiler could be installed in a suitable boat and steamed without any need for further work.
A properly engineered oil firing conversion kit is also offered as an optional extra, using a new Riello RDB 36 kW burner. The burner fits on to the fire hole opening via an adaptor plate and spacer, with Vermiculite insulating blocks placed over the fire grate. The boiler can be switched between coal and oil firing in a few minutes. Boiler evaporation on oil firing is equivalent to forced draught coal firing.

A fully restored Weir horizontal Junior feed pump
18 July 2021
These efficient and sought after pumps become available only very occasionally. Here is a rare opportunity to purchase a fully restored Weir Junior horizontal boiler feed pump in really excellent working and cosmetic condition.
Installation of one of these in a typical steamboat power plant opens up the possibility of considerably increased engine power output for a given firing rate and is well worth considering. The pump can deliver to the boiler against significant flow resistance, so a steaming economiser can be added to the uptake of a water tube boiler or the smoke hood of a fire tube boiler. An exhaust steam feed heater can also be added. Feed rate is smoothly controllable and power is not wasted as with an engine driven feed pump.
This pump has a two and a half inch bore steam cylinder, four inch stroke and a one and a half inch bore double acting water end. It has the well known Weir valve gear and is reliably self starting from any point in the stroke.
It is ideally sized for a steamboat power plant and will keep up with 200lb/hr evaporation at slightly less than ten strokes per minute. A fine adjustment throttle valve is fitted to the steam chest inlet to regulate stroke rate.
It comes complete with a cast iron drip tray and a Dunbar and Slater sight feed mechanical lubricator. It strokes smoothly on just 2psi air pressure.
It was in continuous use until a factory closure and is rust free, both internally and externally. The steam end was virtually unworn and just needed a new set of Weir piston rings. The water end bronze cylinder liner showed some signs of wear and was replaced with a new standard size liner. New Weir water end piston seals were also fitted. The suction and delivery valves are in excellent condition, leak free and with springs intact.
