The Launceston Gasworks is a former industrial site located in the CBD of Launceston, Tasmania. The site was the principal supplier of gas to the City of Launceston before the importation of LPG in the 1970s. The gasworks produced gas by heating coal and siphoning off the gas that it released before refining and storing it on site in a set of 3, steel frame gasometers. The first buildings on site were the horizontal retort buildings built in 1860 from sandstone and local brick. The site was later used by Origin Energy as their Launceston LPG outlet. The site is instantly recognizable by its 1930s, steel braced, vertical retort building with the words "COOK WITH GAS" in the brickwork.
History
Starting in 1826, Launceston was lit with lamps running on sperm whale oil. These lamps were unpopular and local butchers soon replaced these with "slush" lamps that burned animal fat. These lamps were still disliked by many so in 1844 a local man, Doctor William Russ Pugh (a statue of him is located in Launceston's Prince's Square), produced his own coal gas for his house and a year later Benjamin Hyrons lit the Angel Inn with methane gas. As early as 1854, the Examiner newspaper urged locals to consider the creation of a gasworks in Launceston pointing out the numerous benefits and cheaper costs of coal gas as a means of lighting. In 1856 the Launceston City Council engaged Scottish-born engineer, William Falconer of the Hobart Gas Company, to prepare plans for the proposed gasworks. At a public meeting at the Cornwall Hotel on the 18 May 1858, the Launceston Gas Company was formed. The company purchased a marshy paddock near Cimitier Street the same year due to its proximity to the North Esk River in order to build the new gasworks. Machinery from England and suitable builders were assembled in 1859 with the Horizontal Retort Buildings completed in early 1860. On the 5 April 1860, Launceston turned on its new gas street lighting for the first time and oil lamps were replaced by gas. The main source of gas was Newcastle Coal from New South Wales. The gas was extracted by heating the coal until gas was produced. The site of the gasworks was also directly opposite the TMLR rail yards on Willis Street which was also convenient for the delivery of coal. The demand for coal gas continued to grow even after the Duck Reach Power Station was commissioned in 1896. In 1932, the Vertical Retort House was added to the site to increase productivity. The site was expanded to the west in the mid 1900s which involved the removal of Wescombe Street and the historic cottages that lined it in order to make a 3rd gasometer and later an LPG cylinder yard when the site was taken over by Boral and eventually Origin Energy. In 2007 the site was sold and the 3 gasometers were largely dismantled. The cylinder yard has now been built over by the new Centrelink building and car park with additional developments planned to take place in the future.
Notable buildings
Chief engineer's cottage The chief engineer of the site used to live in an ornate cottage on the NE corner of the site. The first engineer was William Falconer from Scotland and many more followed. An unusual feature associated with the cottage was the chief engineer's private, heated swimming pool. It is said to still be there, buried under the courtyard between the cottage and the gas laboratories. The pool was heated by the Vertical Retort Building's boilers and was strictly out of bounds to all workers unless they were needed to fix it. The cottage is now restored and serves as a private residence.
Company office The company office is located next to the chief engineer's cottage, and once looked out across the North Esk until the levee system was built over the wharves. The original building was a brick cottage but in the 1880s it had its facade rebuilt in a Victorian style. The headquarters have now been restored along with the other buildings on the site's north facing Boland Street. Out in front of the company office is one of the original gas lamps used in the city. The company operated 123 gas lamps across the city as well as a special one outside the office. The lamps were removed when the city turned to electric lighting but during restoration work, an original lamp was located and returned to the site where it now stands.
Horizontal retort Built from local brick with sandstone quoining and arches, the Horizontal Retort building was erected in 1860 and is one of the oldest buildings on site. The central portion of the building used to have a 39.3 m (129 ft) brick chimney and housed 18 retorts with room for an additional 6. On either side of the main building were two wings: the western one for the storage of coal imported form NSW and the other being a purifying house which also contained the "smiths" and gasfitters shops. A second coal store, located where the Carbureted Water Gas Building now stands, closely followed the same design. Gas produced in this building was stored in the 15 m (50 ft) diameter No.1 and No.2 Gasometers. The brick chimney was built by A Henderson with Francis and Miller being contracted to build the main building, all at a total cost of £3333. In 1929, this building was flooded to a depth of 4 ft during the great floods of 1929, after which damage was repaired quickly. When the Vertical Retort was built in the 1930s, the Horizontal Retorts were removed along with chimney and replaced with a boiler and a large tar plant in the mid portion of the building with associated 3 oil tanks outside on the southern face. The brick and masonry portion of the eastern wing was re-fitted with 3 exhausters and the steel and galvanized iron portion upgraded to contain 4 more purifiers adding to a total of 8. Today the building is falling into disrepair despite minor restoration work being carried out a few years earlier and most of the sandstone is heavily eroded. The north face of the building is only partially original. The last restoration attempts from the 1980s saw the purifiers removed and converted to conference rooms; closing the originally open air structure with galvanized iron and plate glass bearing the new Gasworks emblem, based on the ventilation hole patterns in the Vertical Retort's walls.
