Internal Fire Museum of Power - Browett, Lindley steam engine

Inverted vertical compound enclosed engine by Browett, Lindley, Works No. 2253, built 1913 and installed in HMS Tiger. It drives a Rees Roturbo 200 kW dynamo. The ship fought in the battles of Dogger Bank and Jutland, and survived. The vessel was scrapped in 1932 and the engine used at Storthes Hall Hospital, Huddersfield. The engine was latterly on standby until 1982 and was acquired by the National Maritime Museum and kept in store. It came to Internal Fire in 2017 and is now steamable but waiting for more boiler capacity. Internal Fire was set up as a museum of the internal combustion engine but has branched into external combustion engines in the form of steam engines. This is in the first steam hall and is one of several significant items.

Internal Fire Museum of Power - Willans central valve engine

The Willans engine was a compact high speed design that could be direct coupled to a generator and revolutionised electrical generation. For a time it was the dominant design and it is claimed that in 1892 68% of all electricity generation was by Willans engines. However, they were progressively ousted by double acting, pressure lubricated high speed engines and then by turbines. The Willans Works moved to turbine production and thus stayed afloat and turbines are still made there today; in a works dating in part from 1897. This engine was built in 1901 and returned to the works in 1957 for preservation. It is a three crank engine with compound cylinders on each crank and developing 140 horsepower at 360 rpm and direct coupled to a dynamo with an open commutator, It came to Internal Fire in 2017 and will turn on steam but is awaiting a bigger boiler.

Internal Fire Museum of Power - Petter steam engine

Petters of Yeovil are best known as manufacturers of internal combustion engines. However they also made steam engines at an early stage of the company's history. This was manufactured in 1893 by James B Petter of Yeovil and is a single acting slide valve engine 4" x 6". It is seen driving a Crompton Dynamo of about 1896 vintage. The picture is 50:50 time and flash, hence the see-through flywheel and the flapping belt. This is a unique engine. Internal Fire started as a museum of internal combustion engines but has branched into steam engines.

Internal Fire Museum of Power - Waller engine

One of the most recent acquisition is a horizontal single cylinder Waller engine with Beales sliding vane exhausters. This was removed from Bath Gas Works in 1975 and moved to Bristol Industrial Museum. It is in Steam Hall 1 and due to space limitations is only fitted with one exhauster. The engine has a Meyer slide valve, single slipper crosshead guide and double web slab crank. The vertical cylinder on the left is the gas pressure governor that uses gas pressure to adjust the speed of the engine.

Internal Fire Museum of Power - Allen 8S30

Solid injection diesel engine built by W H Allen Sons & Co Ltd of Bedford in 1943 for the Radar Research Establishment, Malvern. 8 cylinder 4 stroke with cylinders 240 x 300 mm, 260 kVA at 600 rpm. Drives a 3-phase alternator. Donated by Qinetiq in 2005. This was seen running and made a gorgeous noise - normally aspirated medium speed diesels sound so much nicer than turbo-diesels.

Internal Fire Museum of Power - Sulzer air blast diesel engine

One of, if not the oldest working diesel engine in the country. A Sulzer ID25, 25 horsepower air blast diesel engine of 1913 from Somerford Pumping Station of the South Staffordshire Water Company. This has featured in a television programme about the diesel engine as this is very close to in design to Dr Diesel's earliest commercial engines.

Internal Fire Museum of Power - Belliss & Morcom engine

This is the classic Belliss & Morcom of Birmingham inverted vertical compound enclosed V-type engine. Thousands of these were built and were still quite a common sight in the 1970s and 1980s. They are now much less common and it is nice to see this later type of steam engine on display. This particular one is one of a pair built for St Andrew's Hospital, Thorpe Next Norwich in 1931. The cylinders are 10" & 14.5" x 6" and it was good for 95 BHP at 600 rpm. The engines were removed in 1974 and its twin is displayed at Bressingham - TM0880 : Belliss Morcom & Maudslay’s Ltd Vertical Steam DC Generator

Internal Fire Museum of Power - Pocket Power Station

This meaty piece of kit is a 3 MW power station with a Bristol Siddeley Proteus gas turbine driving an alternator. The end of the turbine is on the right with the hot and noisy bits in a separate room and the exhaust belching fire through the wall. The big grey box is the alternator and the small device on the left is the DC exciter for energising the alternator field coils. This was used at Princetown on Dartmoor. In a remote location like that it is useful for system security and stability as well as peak-lopping. This is a runner usually but not on this occasion. The red and black plaque is a heritage award from the Institute of Mechanical Engineers.

Internal Fire Museum of Power - one of the halls

A typical display area with smaller engines flanked by two big vertical multi-cylinder naturally aspirated diesels. Closest is a Belliss and Morcom while in the background is a W H Allen that drove a vertical spindle pump and a generator. Although Internal Fire commenced as a museum of internal combustion engines it now has a burgeoning steam section. If you want to take a good look at the items and record them photographically you will need at least 4 hours, preferably a day.

Internal Fire Museum of Power - Allen 3S30

Three cylinder solid injection diesel by W H Allen Sons & Co Ltd of Bedford. Built 1932 and good for 80 HP at 425 rpm. It was originally installed in the Fetcham Waterworks, Leatherhead but later moved to Woldingham and ran until the 1980s. It was variously owned before coming to the museum in 2012. During my visit it ran all day and made a slightly unusual but pleasing noise. The museum has a lot of Allen diesel engines but none of their steam engines.

Internal Fire Museum of Power - Clayton & Shuttleworth diesel engine

Many of the museum's engines are arranged in 'rooms' with suitable driven machinery and trimmings. This is a Clayton & Shuttleworth of Lincoln, type JA, built 1923 and developing 20 HP. It is belted to a Crompton 110V dynamo. It is a two-stroke semi-diesel with a blowlamp start. This display dates from 2007.

Chris Allen

Internal Fire Museum of Power - Tangyes MLD7

Horizontal twin cylinder diesel built in 1929. The cylinders are 16" bore x 34" stroke and it develops 168 HP at 250 rpm. It drives a 220V 2 phase Westinghouse alternator. We take it for granted that industrial alternators generate three phase but they didn't always in the days before standardisation and the national grid. I missed seeing this beauty run. Hereford Waterworks Museum has a Tangyes twin but the crankshaft is cracked and it is now electrically driven.

Chris Allen

Internal Fire Museum of Power - triple expansion steam engine

This is a Hathorn Davey inverted vertical triple expansion waterworks pumping engine. It was originally installed at Sutton Poyntz Waterworks in Dorset before being removed to the REME to Bordon Camp, then moving to Leeds Industrial Museum and ultimately back to Sutton Poyntz for erection as an outdoor exhibit. It came to Internal Fire in 2017 and has been returned to steaming condition. I did see it running at about 12 rpm. A larger boiler will improve its performance. It is a small example with drop valve cylinders measuring 12", 19" & 29" bores x 24" stroke.
