Boulton and Watt beam engine – the museum experience

Posted by jerry on June 23rd, 2007 — Posted in Journal, Steam, Technology

In London recently I visited one of my favourite haunts – the London Science Museum, where they have an excellent collection of steam engines, among other things. On a previous visit I managed to coincide with a live steam day when they had several of the engines operating under steam.

One of the most impressive of these is the Boulton and Watt rotative engine – a beam engine of substantial proportions.

On that day I was spellbound by the awesome ‘breathy’ sound of the engine and the impressive sight of the huge flywheel spun up to around 300 revolutions per minute. The sensation of speed and fury was palpable – a really immersive way to come to grips with the impact these engines would have made on a public unused to artificial power on such a scale.

I was disappointed on the most recent visit to find that there was no sign these engines had been recently operated under steam, so they were relegated to static displays that most people hurried past to get to other parts of the museum. Even the reorganisation into themes – which may be fine for a half-hour glance at the highlights – meant there wasn’t a good sense of how these machines evolved from fairly basic low-pressure engines to highly sophisticated efficient and high-power engines that drove the industrial revolution until well into the middle of last century.

While museum practice has changed markedly over the past decade, and mostly for the better, I certainly hope that future museum-goers will have the opportunity to see these machines in action so the sights are enriched by the sounds of the great beam engine – or the almost silence of the huge red mine lifting engine.

In the meantime – Australia’s Powerhouse Museum in Sydney actually has the world’s oldest Boulton and Watt rotative engine – built in 1785 and used for 102 years in the Whitbread Brewery in London.
