Boilers
An extract from the Melbourne Argus of Friday 20 February 1903 that I accidentally came across.
Might be of interest to someone? BELLEVILLE BOILERS. CONCLUDING TESTS. LONDON, Feb. 10. [1903?] The series of tests conducted by the Admiralty to determine the relative merits of the Scotch and the Belleville boilers in warships was brought to a conclusion yesterday by a race between the second class cruisers Minerva and Hyacinth from Gibraltar to Spithead. The Minerva was fitted with Scotch cylindrical boilers and the Hyacinth with Belleville boilers. The Minolta won the race, the Hyacinth breaking down and abandoning the trial. It was subsequently ascertained that the piston rod of the Hyacinth became over heated, and expanded to such an extent that a severe strain was put on the tube which appeared likely to be dislocated. The engineer promptly shut off steam, and thus averted a terrible accident. [sic - entire para]. At the time of the accident, which was 23 hours after starting, the Hyacinth was 40 miles ahead of the Minerva. [The Hyacinth has been unfortunate. In July, 1901, the tubes of the Belleville boiler burst while a trial was being conducted between the two classes of boiler on the same cruisers. At a second trial in October of the same year the superiority of the cylindrical boiler was thought to have been demonstrated. In July last year the Admiralty Water-tube Boiler Committee issued a second report as to the most suit able type of boiler for use in British war ships. In an earlier report the committee recommended that Belleville boilers should not in future he fitted to any British war ships, but that in vessels already completed boilers of this type were to be retained. The later report was more decidedly adverse to the Belleville boiler and favourable to the Babcock and Wilcox type which had recently been more largely used in warships. The committee was unable, however, to recommend a standard boiler for the navy. It held that the water tube boiler was less economical than the cylindrical boiler, and until a more satisfactory type of water tube was obtainable it recommended for large vessels and battleships the cylindrical pattern. The steam pressure for both water tube and cylindrical boilers should be 210 lb per square inch inch [psi]. This, if attained, would have the double effect of economising coal and largely increasing the radius of action for each warship. Lord Selborne, the First Lord of the Admiralty subsequently expressed the opinion that the water tube boiler had a future before it and that even the Belleville boilers would prove efficient if properly manufactured. ] Geoff (YM) |

My favourite boiler was the 3-drum Yarrow. Straight generating tubes so dead easy to clean and superheat elements which were a doddle to change if necessary.
Shame about all that asbestos dust I breathed in as I stood around the boiler room admiring them

HMS Hyperion, a 1930s destroyer, was fitted with two Admiralty pattern Yarrow boilers and an experimental Belville water tube boiler. My father was Chief ERA in her when she was sunk in the Mediterranean. He said they used the Belville boiler as little as possible because it was impossible to maintain a constant water level in it. As the water level rose the steam output dropped and as it dropped the steam output rose. At full power this meant that the speed was going up and down by five knots. As she was ‘Half Leader’ she sometimes lead a half flotilla and apparently station keeping at full power was somewhat ragged!

My favourite boiler was the Burco in the Duty Mess, far more reliable than the ones down the engine room.

Duty Mess Boiler, AKA Geyser
Quote:
Anyway, one fine morning, we forgot about the eggs. Several days later, a plate with festering boiled eggs on was left on the bar with a note saying "WHO HAS BEEN BOILING EGGS IN THE GEYSER". The Chief said the Leckie was "very upset" because the underlying sulphur taste had spoiled his smokoe and could we please stop doing it. So, properly chastised, I set out to "upset" the Leckie again. I set up an empty alarm as "Low Level Egg Boiler". On the next standby, C/E and Leckie present, me on the controls, 2/E and J/E show up too. I then set the alarm off. C/E went to have a look and muttered something about never having seen it before. He turned to the Leckie and asked him to please check the sensor. When the Leckie looked at the alarm, he turned a deep purple colour and started shouting and stormed out of the ER. Everyone was laughing but after the hilarity had subsided, Bill Turner, the C/E, put on his sternest face and told us that it was the end of practical jokes on the Leckie. We later learned that the Leckie stormed off to tell the Master whose first reaction was to laugh his head off! The C/E was summoned and he solemnly made the peace with the Leckie and told him that there would be no more tricks. He also told him to lighten up. It seemed to relax the Leckie and afterwards he loosened up and became a good shipmate. Next trip, I was having a beer with him and he started laughing, remembering the stunt. He admitted that it was rather good and asked us to not remove the "alarm"! So, if you are onboard Cape Henry, ex Barber Priam, let me know if the LL EGG BLR alarm in the CR is still there! PS: I also altered the alarm schematic to include the alarm in the right place. Rgds. Dave Last edited by Makko; 15th August 2020 at 17:45. |
