Gas Turbine Efficiency - overcoming your power problems

EMISSIONSMaking harmful emissionsimpossibleAbove: Janikowo power plant in Poland -another FGD contract for Alstom.In 2012 and 2013, Alstom will be commissioning the largest environmental powerplant project in Europe by building Russia’s first desulphurisation system at units 1&2of the Cherepetskaya power plant in the Tula region. WIP has the story.Alstom, the world’s leading supplierof air quality control systems(AQCS) for power plants has beenawarded contracts in excess of €170m forenvironmental control systems to be usedin the power generating sector.The company currently boasts theworld’s largest installed base in airpollution control systems with over100,000 MW of wet, seawater and dry fluegas desulphurisation systems (FGD)installed worldwide.It has also installed more than 210,000MW of electrostatic precipitators (ESP)worldwide. Alstom’s FGD systems removesulphur-dioxide released from coal-firedpower plants and ESPs are used to removeash particles created during thecombustion process.Recently introduced regulations onpollutants are fuelling the growth of theenvironmental control systems marketworldwide. This trend is set to continue,says Alstom, due to the large number ofinstalled coal-fired power plants in NorthAmerica and Europe and the numerousnew fossil-fired power plants being builtin Asia, particularly in India and China.This is a result of high demand from thesefast-growing economies.In Estonia Alstom has won an order fromthe state-owned utility Eesti Energia toCherepetskaya: OGK-3, the powerplant operator. now complies withRussia’s strict dust and SOxemissions regulations for newplants.supply and install twoFGD systems at NarvaSteam Power Plants inEstonia, as part of anational drive to reduceemissions of sulphurdioxide.Last year a contractwas signed betweenAlstom and Eesti Energiato install two FGDsystems on two ofNarva’s twelve 200 MWunits. Two more identicalsystems are on order.Alstom has previouslysupplied enhanced dust removal systems(electrostatic precipitators) to EestiEnergia and has a long term serviceagreement in place with Narva PowerPlants since 2000. The Narva PowerPlants power generation complex, basednear Narva in Estonia, consists of theworld's two largest oil shale-fired thermalpower plants, which together generateabout 95% of the country’s total powerproduction.In 2012 and 2013, Alstom will beginbuilding Russia’s first desulphurisationsystem at units 1&2 of the Cherepetskayapower plant in the Tula region.Alstom will build an integrated dry fluegas desulphurisation system with electrostaticprecipitators for two new 225 MWcoal-fired boilers. Under the terms of thecontract with EPC contractorTechnopromexport, with whom Alstom hasworked in the past on projects in Europeand Asia. Alstom will supply theengineering, equipment, erection andcommissioning supervision, as well asproviding training. Alstom's FGD systemsare market reference worldwide and willenable OGK-3, the power plant operator,Cherepetskaya power plant: Alstom will build anintegrated dry flue gas desulphurisation systemwith electrostatic precipitators for two new 225MW coal-fired boilers.Narva, Estonia.to comply with Russia’s strict dust andSOx emissions regulations for new plantsin a cost-effective way.Andreas Lusch, Senior Vice President andHead of Thermal Systems at Alstom toldWIP: “Alstom is fully committed tosupplying efficient, cost-effective airquality control systems for all types offossil-fired power plants. These latestawards are further proofs that powerplant operators worldwide value ourenvironmental control technologies.”Flue gas desulphurisation (FGD) systemsremove sulphur-dioxide and particulatematter released from coal-fired steamgenerators.W ORLDWIDE I NDEPENDENT P OWER • MARCH 201035
