Ecologization and renovation of the heating plant in Planá nad Lužnicí. Fuel tests have been in progress in the boiler K6 which is under construction. The contractor is planning to finalize works and hand the K6 boiler over to C-Energy Bohemia s.r.o. on 30th October 2015; after that the whole project of Renovation of the heating plant in Planá nad Lužnicí will be completed. Structures and technologies installed on the site during this project include: 4 gas motor-generators (9 MWe output each), 4 HRSG boilers which utilize heat from motor exhaust fumes and produce steam (4 tons of steam/hour/each); two fifty-year-old boilers were dismantled and replaced with two new modern coal boilers (40 tons of steam/hour/each); a new desulphurization unit has been constructed, which significantly reduces the amount of emissions produced by the plant and at the same time enabled the plant to burn also higher-sulphur-content coal. The “smoke” coming out of the chimney of desulphurization absorber is no real smoke, it is in fact cleansed water steam free of all and any impurities. We owe to point out that all the new equipment was built and commissioned while the rest of the plant was in operation and continued supplying heat and electricity to all customers. Photographs from the construction process are available in the PHOTOGALLERY.
TG 3 renovation – The renovation of the turbine-generator was successfully completed as of 30th September 2015. The new rotor started turning at the beginning of September and the whole set was adjusted, tuned and commissioned during the month; Photographs from the TG3 renovation are available in the PHOTOGALLERY
The project of Renovation of the heat distribution system was be completed in September. Losses have been reduced thanks to new dimensions of pipelines which suit the current needs of customers better and thanks to the use of modern pre-insulated pipeline technologies; most buildings will now be heated with the use of hot water not steam, which is less economical.
