Oil burner (engine) explained

An oil burner engine is a steam engine that uses oil as its fuel. The term is usually applied to a locomotive or ship engine that burns oil to heat water, to produce the steam which drives the pistons, or turbines, from which the power is derived.

This is mechanically very different from diesel engines, which use internal combustion, although they are sometimes colloquially referred to as oil burners.[1]

History

A variety of experimental oil powered steam boilers were patented in the 1860s. Most of the early patents used steam to spray atomized oil into the steam boilers furnace. Attempts to burn oil from a free surface were unsuccessful due to the inherently low rates of combustion from the available surface area.[2] [3]

On 21 April 1868, the steam yacht Henrietta made a voyage down the river Clyde powered by an oil fired boiler designed and patented by a Mr Donald of George Miller & Co.[2] [4] Donald's design used a jet of dry steam to spray oil into a furnace lined with fireproof bricks. Prior to the Henrietta’s oil burner conversion, George Miller & Co was recorded as having used oil to power their works in Glasgow for a “considerable time”.[4]

During the late 19th century numerous burner designs were patented using combinations of steam, compressed air and injection pumps to spray oil into boiler furnaces. Most of the early oil burner designs were commercial failures due to the high cost of oil (relative to coal) rather than any technical issues with the burners themselves.[2] During the early 20th century, marine and large oil burning steam engines generally used electric motor or steam driven injection pumps. Oil would be draw from a storage tank through suction strainers and across, viscosity reducing, oil heaters. The oil would then be pumped through discharge strainers before entering the burners as a whirling mist. Combustion air was introduced through special furnace-fronts, which were fitted with dampers to regulate the supply. Smaller land-based oil burning steam engines typically used steam jets fed from the main boiler to blast atomized oil into the burner nozzles.[5]

Steam ships

In the 1870s, Caspian steamships began using mazut, a residual fuel oil which at that time was produced as a waste stream by the many oil refineries located in the Absheron peninsula. During the late 19th century Mazut remained cheap and plentiful in the Caspian region.[3]

In 1870, either the SS Iran[3] or SS Constantine[6] [7] (depending on source) became the first ship to convert to burning fuel oil, both were Caspian based merchant steamships.[3] [6]

During the 1870s, the Imperial Russian Navy converted the ships of the Caspian fleet to oil burners starting with the Khivenets in 1874.[3]

In 1894, the oil tanker SS Baku Standard became the first oil burning vessel to cross the Atlantic Ocean. In 1903, the Red Star Liner SS Kensington became the first passenger liner to make the Atlantic crossing with boilers fired by fuel oil.[7] Fuel oil has a higher energy density than coal and oil powered ships did not need to employ stokers however coal remained the dominant power source for marine boilers throughout the 19th century primarily due to the relatively high cost of fuel oil.[3] Oil was used in marine boilers to a greater extent during the early 20th century. By 1939, about half the world’s ships burned fuel oil, of these about half had steam engines and the other half used diesel engines.[6]

Steam locomotives

Oil burners designed by Thomas Urquhart were fitted to the locomotives of the Gryazi-Tsaritsyn railway in southern Russia.[2] Thomas Urquhart, who was employed as a Locomotive Superintendent by the Gryazi-Tsaritsyn Railway Company, began his experiments in 1874. By 1885 all the locomotives of the Gryazi-Tsaritsyn Railway had been converted to run on fuel oil.[8]

In Great Britain, an early pioneer of oil burning railway locomotives was James Holden,[9] [2] of the Great Eastern Railway. In James Holden's system, steam was raised by burning coal before the oil fuel was turned on.[10] Holden's first oil burning locomotive Petrolea, was a class T19 2-4-0. Built in 1893, Petrolea burned waste oil that the railway had previously been discharging into the River Lea.[11] Due to the relatively low cost of coal, oil was rarely used on Britain's streamtrains and in most cases only where there was a shortage of coal.[12]

In the United States, the first oil burning steam locomotive was in service on the Southern Pacific railroad by 1900.[13] By 1915 there were 4,259 oil burning steam locomotives in the United States, which represented 6.5% of all the locomotives then in service.[13] Most oil burners were operated in areas west of the Mississippi where oil was abundant.[13] American usage of oil burning steam locomotives peaked in 1945 when they were responsible for around 20% of all the fuel consumed (measured by energy content) during rail freight operations.[14] After WW2, both oil and coal burning steam locomotives were replaced by more efficient diesel engines and had been almost entirely phased out of service by 1960.[14]
