the recommended factory address for lianyungang hongyang congeneration project is xuwei port,south of lianyungang port, which is the main construction harbor industry, it is located in the south of xigang lake in harbor port, south-west of m3 ployt. the north-west of the factory address in xigang lake, the other three sides are the park planning roads, 700m from east to west, 560m from south to north, the available area is 40hm2. the project scale of lianyunggang honggang congeneration is 3xcb40 draw back type thermoelectric unit 4x440t/h high temperature and super high pressure pulverized coal boiler, all of them are now under infrastucture, #1~3 boiler and #1 steam turbine are almostly completed. #1 bolier will begin successively to supply heat,the design parameter of desulfuration,denitration and dedusting is as below:
de-noxadopts selective catalystic reduction process, denitration reactor is placed between boiler economizer and air pre-heater, and will not set exhaust by-pass system. it will adopt 2 1 layout, and the reductor is liquid ammonia,the denitration efficiency is no less than 80%. according to boiler technical regulation, the discharge of the boiler economizer nox is no more than 350mg/nm3.
flue gas desulfurization adopts ammonia process of desulfurization, the flue gas desulphurization system design parameter is: desulfurization design coal sar=1.2%, inlet so2 content is 2958mg/nm²(dry basis, 6%oxygen content), sulphur removal efficiency is no less than 97%, so2 emission concentration is no more than 100mg/nm³.
each boiler of flue gas dust removal adopts one bag filter, the dustiness in the inlet dirt catcher is 29g/nm³, the dust concentration in the outlet dirt catcher is no more than 20 mg/nm³.
according to “the notification about issuing <>” by national development and reform commission (development and reform energy [2014] no.2093), <> (jiangsu province office send [2014] no.96) and << the notification to implement the coal-fired power plant ultralow discharge electrovalence supportive polices relevent questions>> (development and reform price [2015] no.2835), the documents have increasingly strict requirements on the fume, so2, nox, mercury and its compound emission concentration in the flue gas. lianyungang hongyang thermoelectricity co., ltd plans to istart ultralow emmission reform on the currently 4 stoves in the power plant, with the reform target of dust emission concentration is no more than 10mg/nm³, so2 emission concentration in no more than 35mg/nm³, nox emission concentration is no more than 50mg/nm³.
according to the regulations of << law of the people’s republic of china on environmental impact assessment>>, <>, the project need to send the “construction project environment impact list” to local environmental protection department for approval. authorized by lianyungang hongyang thermoelectricity co., ltd, jiangsu zhisheng environment technological co., ltd will make the environmental impact report to environmental protection department for approval.
