Study On Schedule Control Of Raishan Coal Gangue Power Plant

Baishan coal gangue power plant is a coal gangue and low calorificvalue of large thermal power plant fuel for power generation, with thenational environmental policy continues to strengthen, the current two unitsfacing to practical problems of denitrification transformation, the newlypromulgated the State Environmental Protection Department of the"thermal power plant air pollutant emission standards"(GB13223-2011)closing time has been identified as the July1,2014emission standards. Inorder to meet the emission standards, Baishan coal gangue power plantdecided to adopt the EPC general contract mode on the two generatingunits are running for denitrification transformation.According to the project requirements, we as a EPC generalcontractor to Baishan coal gangue power plant to the time schedule andconstruction scheme, but before the project starts, changed some externalconditions: one is the reason design subcontract units due to lack of designstrength, over time than the commitment plan20days lag time; two is fromthe USA imported2sets of flow control pump (which is the core equipmentof the project) is influenced by the export products restricted, due to latearrival10days; three is the denitrification process interface processarrangement may be in the original plan based on the delayed1months tohave the opportunity to carry out by the owners. Coordinate the Power GridCorp stop; four is the legacy of engineering bidding denitration reducingagent selection scheme has not been finalized, but the scheme selectionwill directly affect the duration results, the need to make a decision as soonas possible; five is the construction subcontracting units for workers owedwages to workers refused to start, whether the project can start onschedule cannot be determined. These are all questions posed a challengeto the current construction progress control. A series of questions about the impact of the project progress, we areanalyzed one by one, from the design of process, equipment supply,process selection, duration compression, human resources management,put forward a series of solutions, and from every man, machine, material,method, ring aspects made the guarantee measures scheme. Through thedemonstration, the schedule scheme is feasible, can guarantee the projectprogress according to plan.At present the different capacity circulating fluidized bed boiler hasbeen put into operation in China has reached more than3000units, thetotal capacity of more than90000MW, the capacity of300MW circulatingfluidized bed boiler has been close to50units, are facing denitrificationtransformation problem, Baishan coal gangue power plant flue gas thedenitration renovation project is the first domestic same type unitdenitration renovation project, the progress of control problems andsolution of the synchronization to carry out on many domestic circulationfluidized bed boiler plant denitration renovation work to provide reference.
