Colenso Power Station was taken over by ESCOM in January 1927, but the station had been built and originally commissioned by the Railway Administration for the electrification of the Glencoe to Pietermaritzburg line. The principal equipment installed at Congella 2 consisted of the following: The installed capacity of the Durban Corporation's Alice Street Power Station when negotiations were started with ESCOM was 14,95 MW (including 1,5 MW of obsolete plant) and the maximum demand on the municipal system was only 9 MW. (van der Bijl & Damant 1933:52-54; ESCOM Annual Report 1948:36), The initial plant consisted of two 12 MW generators and four boilers. The first set at Congella 2 (designated No.7) was eventually commissioned after the war, being put on load for the first time on 27 February 1946. During 1929, the first full year of production at Congella, the net maximum power produced was 15,5 MW and the electricity sent out amounted to 78,873 GWh. There was no such thing as one man doing a specific job. Merz was again in South Africa in September and October 1923, and proposed that ESCOM erect the new power station for the purpose of giving a supply to the Corporation and that the station be extended immediately the Railway Administration decided to electrify the Durban to Pietermaritzburg line. This power station consisted of two 1 MW Willans Parsons turbines driving 6,6 kV alternators and four high-speed reciprocating engines driving dc dynamos, and ran until 1912, when a bulk supply was taken from the Municipality. With the aid of three engines from the City Fire Brigade partial supply was restored by 08:00 next morning and normal supplies 30 hours later. Unlike Congella 1, each boiler at Congella 2 was to have its own mills for pulverising the coal. (ESCOM Golden Jubilee 1923-1973:14; ESCOM Annual Report 1926:5, 15), The primary objective in building Congella was to supply the growing needs of the Durban Corporation, and the station was to be extended immediately the Railway Administration decided to electrify the Durban to Pietermaritzburg line. The Power Station - Get It On (Bang a Gong) - YouTube. The replacement set was lost at sea in 1943 when the ship delivering it was sunk by enemy action. I re-bladed two turbines with my own hands. Come entrare nella Vodafone Station di Salvatore Aranzulla. Loading conditions attributable to the war and the non-delivery of the new plant for Congella 2, had not helped matters. L'installazione è completa quando le spie LED sono accese, fisse e di colore bianco5. Esegui un factory reset. Congella Power Station was also flooded on December 29, 1977 when a severe storm caused the Umbilo River canal to burst its banks.

However, power was supplied from Colenso Power Station for the whole of the railway traction load in Natal, which then extended 186 miles [299 km] south-east from Colenso to Durban and by 1938 also 135 miles [217 km] northwards to Volksrust and 142 miles [229 km] towards Bethlehem. These were the first in South Africa. Capital expenditure to the end of 1938 was £1 453 334, but this included expenditure on the South Coast distribution system. The power station ash was initially run into a sump from where it was pumped to settling dams in low lying areas of the neighbourhood which were being reclaimed. The moist gasses also set up corrosion in the steel stacks, which were later lined with gunite over which a silicate coating was applied. In: The Transactions of the South African Institute of Electrical Engineers, Vol. Figures of water consumption before 1973 are not available. However, the problem was still not eliminated. Since the station drew its cooling water from the sea, its suction chamber was located below sea level from where the water was pumped to the condensers. A second 40 MW set was commissioned in 1948 and a third in 1951, but the boiler plant ordered with this last set was not completed until 1954. In 1944 another system was being designed to transport the fly-ash by rail. The original intention in 1925 was to transfer two stoker-fired boilers as well and to convert them to burn pulverised fuel, but this plan was not carried out. SPEDIZIONE GRATUITA su ordini idonei (The Cape Town City Council commissioned the first 40 MW set in South Africa at their Table Bay Power Station in February 1939, and had three 40 MW sets in full commercial operation by November 1939. The canal emptied into the bay, but on that particular occasion the flow of the storm water was adversely affected by a high tide.

A second 40 MW set (No.8) was commissioned in 1948 and a third (No.6) in 1951, but the boiler plant for the final extension was not completed until May1954. The Hon. The second chimney was completed in 1948. I cookie ci aiutano a rendere migliori i nostri servizi, utilizziamo cookie tecnici e di profilazione. (ESCOM Annual Reports - Tables of Power Station Operating Statistics), There were several power failures at Congella due to switchgear faults. But he also recalled how in the first few months of operation, before water sprays were installed at the base of the chimneys, residents of the surrounding suburbs were extremely unhappy about the ash fall-out and complaints were rife. Congella had been in service for more than 50 years when it was finally decommissioned at the end of 1978. Lo storico edificio è collocato all’interno di uno spazio di forma circolare (“The circle”) ovvero un vasto specchio d’acqua, una superficie orizzontale riflettente che enfatizza il complesso originario in mattoni. The installed plant capacity at Congella 2 was then 120 MW and at Congella 1 was 86 MW, as the two 6 MW sets had been transferred to Kimberley in 1949. © Copyright 2021 Vodafone Italia S.p.A. - Partita IVA 08539010010 - REA: 974956, cliccare OK sulla finestra con il messaggio, entrare nella sezione "Station" (Bottone in basso a destra), compare il messaggio "Opzione momentaneamente non disponibile", utilizzare lo smartphone o PC collegati alla Station, accedendo alla pagina http://vodafone.station (sezione Avanzate > Imposta Password), all'interno della pagina compare la lista dei nomi dei dispositivi associati preceduta da "Client-", identificare quello corrispondente al "nome dispositivo", riavviare l'applicazione con lo smartphone collegato in Wi-Fi alla Vodafone Station. This caused the water from the bay to advance nearly 500 m up the canal. Figures of water consumption before 1973 are not available. Sales amounted to 6,026 GWh by 1908 and 21,998 GWh by 1917, the installed capacity at the Alice Street Power Station then being 10 MW. Outages to consumers lasted from a few minutes to 3½ hours. Affidabilità e prestazioni ottimali A partire da 1.157,76 €. On 13 May 1955, failure of a 33 kV circuit breaker caused all supplies to be interrupted for a short period. After September 1972, when duplicate 400 kV transmission lines had been commissioned, all boilers at Congella 1 were decommissioned as well as one of the 12 MW generators. It was then that the power station got the nickname "Old Smokey" and it was quite common to arrive at work in the morning to find women standing at the power station gates holding shoe boxes of soot. Statistics for the following years are given below: Water for boiler make up was supplied from the Durban Municipality. Electrostatic precipitators were installed on boilers 5 to 8 and Howden multiple cyclone dust collectors on boilers 1 to 4. The power station had drowned!" Share. Jeffrey Fairbanks recalled the team spirit at the station in earlier years: "All the maintenance work was carried out at the station itself.

(ESCOM Annual Reports 1949:31, 1951:34, 1954:38), The power station ash was initially run into a sump from where it was pumped to settling dams in low lying areas of the neighbourhood which were being reclaimed. With no electric power available, the City Fire Brigade brought their engine-mounted pumps to assist, but there was nowhere to discharge the water until the general flood level had subsided. 1929    The first full year of production, 1932    The year installed capacity was increased to 48 MW, 1939    The first full year with Congella 1 at its final installed capacity of 98 MW, 1945    The final year before Congella 2 was started up, 1949    The first full year after the second set at Congella 2 had been commissioned, 1951    The year in which the final set had been commissioned, also the year of highest thermal efficiency, 1954    The year of maximum net production (GWh) and also the year in which Umgeni was started up, 1960    The year of maximum net power (MW), 1971    The year Natal was first linked up to the national 400 kV network by a single transmission line, 1973    The year after Natal was linked up to the national 400 kV network by duplicate transmission lines.
