Commander L G Dennis, Marine Superintendent (Lakes) (East African Railways and Harbours) in his book "The Lake Steamers of East Africa" 1996 Runnymede,P152-3 writes that it was a railway Marine petrol driven motor boat of 14hp, built in 1930s, 28 ft in length. It was fitted with a mock-up steam boiler and funnel made in the (Butiaba) Marine workshops and that oily rags were burnt to create smoke.
In an interview Daily Press, Norfolk, Va June 06 1997, James Hendricks Snr was reported as explaining that "It really is a vintage African boat,built in 1912 for a British railway company that used it on a lake in Uganda. She originally had a diesel engine--".
Yes it was a motor boat,originally possibly petrol, later diesel, most likely built in the Marine workshops in Butiaba. It appears from a photo in Hepburn's book that a second very similar boat was sectioned into two to create fore and aft situations for close-ups. This sectioning was necessary to allow access for the very large technicolor cameras of the time.
So, it is pure invention to claim African Queen was a steamboat built by either Lytham Shipbuilders or by Abdela & Mitchell
They use diesel engines.
The effect of dry steam entry into a wet steam filled vessel will promote condensation in the vessel. However, it will be less wet because of the dry steam.
Internal combustion engine is where the fuel is ignited in the cylinder to make the piston move, petrol or diesel. A steam engine has an external pressure vessel to supply the steam to the cylinder to push the piston. the is no combustion in the engine as such.
The main difference between a diesel and a steam engine is the diesel engine is an internal combustion and the steam engine is external combustion.
"SS stands for Steam Ship for commercial or private vessels that are under power. Vessels that are gasoline or diesel powered are marked "MV", or Motor Vessel.
SS stands for Steam Ship but the minnow was powered by diesel motor and should have had the prefix MV (marine vessel or motorized vessel) however the producers initials were S.S and that is my personal theore as to where it came from, as Minnow came from Minow the head of the FCC
The Diesel engine
Of an individual diesel engine and an individual steam engine of the same energy output the diesel engine would be less polluting. It is far more efficient. However, there are far more diesel engines than steam engines in the world today so overall diesel engines pollute more than steam engines.
Boiler is basically a pressure vessel in which this boiler aims to heat the surroundings which is a pressure vessel.
Steam, diesel, electric, sail, gas turbine, maglev and railplane (1934). The different kinds or steam locomotives, diesel locomotiveas, etc. There are three diffrent types: steam, which isn't used much nowdays, diesel, which burn diesel to run power generators, and electric, which run on electricity.
