	A4 Pacific
		The A4 pacifics were designed for low consumption of coal and water on all kinds of services; passenger and freight.
		With the introduction of the double-exhaust Kylchap funnel, the consumption levels of the above dropped even more, gaining more revenue to their operators.
		On July 3 1938 the Mallard with the newly modified funnel to Kylchap, set a world speed record of 125 mph (201.2 km/h), pulling six cars plus a dynamometer car.

	The Peppercorn A1 Pacifics
		In May 1948, it was decided to fit the Kylchap exhaust arrangement.
		As with the Peppercorn A2s, there was insufficient space in the smoke box for both the Kylchap exhaust and the self-cleaning apparatus.
		One problem with the Kylchap exhaust arrangement, was that the sound of the ejectors whilst standing in the station was considerably louder than tannoy announcements.

	Steam locomotive basics - section 9, blastpipes
		Probably the most advanced method of draught improvement was with the Kylchap design, perfected by the French engineer Andre Chapelon.
		Beneath each chimney orifice were two petticoat pipes, shaped to split the four jets and then combine them again as a single jet that was exhausted through the chimney.
		Locomotives that were fitted with the Kylchap exhausts were noted for their exceptionally free running.

	The Ultimate Steam Page
		The Kylchap draws in gases from more than one level of the smokebox, which Chapelon believed to be an imporant feature in providing an even gas flow through the many tubes of the boiler.
		Later Kylchap exhausts used two levels of entrainment and two or even three stacks.
		This drawing shows the Kylpor exhaust system developed by L. Porta from the Kylchap as applied to the 2-10-2s of the Rio Turbio Railway in Argentina.

	The Modifications - Restoration & Mainline Running
		Because the five nozzles of the Bulleid blastpipe were angled outwards it was felt that this might not be typical, but the ‘A2’ Kylchap choke area was found to be half as big again as that of the Duke.
		Mr Daniels stated that he had asked for a kylchap type chimney to be fitted to the Duke when under construction and he reiterated this preference which was acceded to.As André Chapelon, the inventor of the Kylchap blastpipe, was dead, the only solution was to produce one using existing designs as a foundation.
		Following the manufacture of the new Kylchap chimney assembly for 71000, a rumour had persisted that originally, prior to Swindon taking charge of chimney design, something similar to a Merchant Navy assembly had been proposed.

	The Mallard
		The record run of the "Mallard" on July 3rd, 1938 was made with a six car streamline set plus a dynamometer car, with a total tare of 240 tons.
		The Mallard was chosen because it was one of the four engines with Kylchap exhaust at that time.
		I believe that the Mallard was the first A4 fitted with Kylchap exhaust and had had about three months of service at the time of the speed run.

	The Gresley V2 2-6-2 Prairie 'Green Arrow' Class
		By 1934, the proposed design was streamlined and was essentially a 2-6-2 version of P2 Cock o'the North, and included features such a Kylchap exhaust, rotary cam poppet valve gear, and ACFI feed water heater.
		This build-up of steam led to the order in December 1952 fit a single-seat regulator as standard on all V2s and LNER Pacifics (excluding those with multiple valve regulators).
		This resulted in performances comparable to a Pacific, and the recommendation was made to convert all V2s to use this arrangement.

	LNER Class A4 - Wikipedia, the free encyclopedia
		The application of internal streamlining to the steam circuit, higher boiler pressure and the extension of the firebox to form a combustion chamber all contributed to a more efficient locomotive than the A3, consumption of coal and water being reduced.
		A further improvement to the design was the double-exhaust Kylchap blastpipe first introduced on 4468 Mallard, built in March 1938.
		This device improved the free-steaming capabilities of the locomotives further, and the final three locomotives of the class (4901 Capercaillie, 4902 Seagull and 4903 Peregrine) were also fitted with the Kylchap exhaust from new, and eventually the rest of the class were fitted with it (by BR) in the late 1950s.

	A4 Pacific - A4Pacific
		The A4 pacifics (with the 4-6-2 wheel arrangement) were designed for low consumption of coal and water on all kinds of services; passenger and freight.
		With the introduction of the double-exhaust Kylchap blastpipe, the consumption levels of the above dropped even more, gaining more revenue to their operators.
		This class of locomotive was also noted for its streamlined design, which not only assisted its speed, but also made it an attractive subject for artists.

	The KylChap exhaust (or blast!) system
		It's the "second stage" of the KylChap blasting (literal translation of French technical word for this part of a Marc Seguin's based design - I mean multiple smoketubes - of steam generator is exhaust, that's why I use it quite often and erroneously.
		The version shown here is the final one, called 1K/1C used in single, dual (called 1K/1C-1K/1C and not 2K/2C as often read) or triple (242 A 1) paralleled configurations according to the capacity and to the quantity of steam to be produced by the boiler.
		Relative positions and proportions of the various nozzles, independently of general dimensions, proven to be absolutely critical parameters to obtain an efficient KylChap, as are their perfect concentricity and alignment (precision for "would be" KylChap modellers).

	Kylchap
		It would also ensure a more even flow through all the firetubes, rather than concentrating the suction on one area.
		Kylchap exhausts were also fitted to some British-built export locomotives, primarily Garratts for Africa, but the only other nation to take them up in quantity was Czechoslovakia, where they seem to have been quite common.
		The Kylchap wasn't the only advanced steam locomotive exhaust: another design, the Lemaître, had some success in France and England; noted Argentinian engineer Livio Dante Porta designed several, the Kylpor, Lempor and Lemprex designs; and several US railroads including the Norfolk and Western used a concentric nozzle known as the waffle iron exhaust.

	71000 Duke Of Gloucester - The Real Life Fairytale
		Mr Daniels stated that he had asked for a kylchap type chimney to be fitted to 'The Duke' when under construction and he reiterated this preference which was acceded to.
		As André Chapelon, the inventor of the Kylchap blastpipe, was dead, the only solution was to produce one using existing designs as a foundation.
		Mr Daniels outlined the important criteria and the starting point was the Kylchap assembly on preserved 'A2' Pacific No 532 Blue Peter.

	The Ultimate Steam Page
		It was originally built as a lead mine railway, but is now a tourist line.
		During 1991, this device was designed, fabricated, and installed on the locomotive to improve the drafting of this locomotive (the worst of the fleet).
		After the initial success of the Kylchap modification to no. 8, Shaun McMahon and Nigel Day designed and fabricated a Lempor exhaust system for installation on locomotive no. 7.

		Most of the new designs were therefore outfitted with Kylchap blast pipes and double chimneys.
		Among the most important were the mechanical stoker, the Kylchap type double exhaust nozzle (after cooperation with Chapelon from France), the Hulson type shaking grate.
		They have a double chimney, a long combustion chamber, one thermosiphon, two arch tubes, Kylchap exhaust pipes, an exhaust steam injector, they are stoker fired, have a five axle tender (type 935.2, as class 556), and have 3 cylinders with 500 mm diameter, Trofimoff type valves.

		In 1934 Flying Scotsman was the first steam locomotive to authentically achieve a speed of 100 mph.
		It was rebuilt in 1947 with a higher pressure boiler and in 1959 with a Kylchap.
		A double exhaust arrangement and chimney improved the steaming capability of the boiler with inferior coal.

	smoke deflectors - Trains.com Forums
		When fitted to locomotives, the KylÃ¤lÃ¤ and Chapelon "Kylchap" exhaust system often required smoke deflectors to be fitted because of the softer exhaust.
		On the other hand the Kylchap exhaust was very efficient, but wouldn't lift the smoke, leading the railway to fit the German style smoke deflectors after a few months or years.
		This was recently demonstrated when the only surviving A3 - "Flying Scotsman", which has the Kylchap exhaust fitted - was recently run with the smoke deflectors removed for aesthetic reasons.

	71000 DUKE OF GLOUCESTER - Caprotti
		The valve events provided by A.L.E. for 71000 were B.R.’s choice.The changes currently being made follow from recommendations made by L.T.Daniels after initial main line testing in 1990.
		The transformation of performance resulting from fitting of the Kylchap blastpipe as advocated by the Caprotti engineer during restoration was the pivotal episode in the 71000 legend.After the initial main line test run Daniels recommended increasing the blast pipe diameter, and modifying the exhaust event to give a slightly later release.
		The former change was made but the latter has waited until now to be trialed.

	European Tribune - Comments - Monday Train Blogging: Design Dictators
		Good point, tough to Chapelon's credit, I note he invented a more efficient chimney, the KylChap system (tho', further developing Finnish engineer Kylala's invention, it's in the name!), and authored a unified theory of the dynamics of locomotives running on wheels.
		The KylChap work was a large part of the base for the acheivement (not so real, but quite celebrated none the less) of a local hero here in Doncaster.
		Sir Nigel Gresley is most famous for the Mallard, which holds a (dubious) speed record, but certainly deserves an award for beauty in my mind...

		Gresley had kept an eye on his contemporary across the Channel, Andre Chapelon, who had designed a 4-8-0 compound locomotive for similar work.
		Gresley did not use compounding but he incorporated the Kylchap (Kylala-Chapelon) blast pipe and chimney plus enlarged, streamlined steam passages and ports.
		The French influence was continued by the fitting a ACFI feedwater heater.

		In 1946, the Scotsman was upgraded from A1 class to A3 class and outfitted with a higher-pressure boiler; you will notice the A3's distinctive square smokebox covers on the Scotsman today.
		In 1959, the Scotsman was fitted with a Kylchap double exhaust arrangement and chimney to improve the steaming capability of the boiler with inferior coal.
		The Scotsman is now a left-hand drive locomotive, but in the 1920s the engineer sat on the right.

		This was done on some of the locos in service, resulting in 'pink elephant ears'.

		He was recruited to find out why the Pacifics (4-6-2) of the POR could not better the performance of their Atlantic 4-6-0s.
		In 1926, he worked with the Finn Kylala and they jointly invented what became known as the Kylchap double blast pipe and chimney that significantly improved draft but minimised back-pressure.
		However, it was Chapelon's work on thermodynamics that revolutionised steam locomotive design.

		Most notable were a small batch of double 4-8-2 Garratts from Henschel of Germany, with much in common with the later types in South Africa itself (the GMA/M Classes).
		They were larger in the boiler, and had an unusual double Kylchap (remember M. Chapelon’s invention described some months ago?), a feature thought to be unique in Garratt practice.
		It is sad that independence saw a serious deterioration in the condition of these and other fine machines; it would be a sad pilgrimage to Gondola today, even if it were permitted.

	Collectable gifts models, ornaments and figurines made with coal The Mallard steam locomotive LNER 4468 made with coal
		It broke the German 1936 record of 200.4 km/h (125 mph).
		Mallard was the perfect vehicle for such an endeavour; one of the A4 class of streamlined locomotives designed for sustained 100+ mph (160 km/h) running, it was one of a small number equipped with a double chimney and double Kylchap blastpipe, which made for improved draughting and better exhaust flow at speed.
		The A4's three-cylinder design made for better stability at speed, and the large 6 ft 8 in (2.032 m) driving wheels meant that the maximum revolutions per minute was within the capabilities of the technology of the day.
