燃煤電廠如何從“黑色’變成“綠色”，在中國首都，華能北京熱電廠闖出了一條燃煤電廠清潔高效、綠色發(fā)展之路。
清潔高效燃煤電廠
華能北京熱電廠
中國華能北京熱電廠位于北京東郊，擔負北京市10%的供電、70%的供氣和30%的集中供熱任務，是中國首個同時具有煙氣脫硫、脫硝、二氧化碳捕集及城市中水利用的熱電冷三聯(lián)供燃煤電廠。
中國第一家二氧化碳捕集電廠。2008年7月16日，建設投產(chǎn)了國內(nèi)首個“燃煤發(fā)電廠年捕集二氧化碳3000噸試驗示范工程”，開啟了國內(nèi)燃煤電廠二氧化碳捕集的先河。
中國供熱容量最大的電廠。安裝了四臺熱電聯(lián)產(chǎn)燃煤機組，裝機84.5萬千瓦，供熱能力1160百萬大卡/時，約占北京市集中管網(wǎng)供熱量的30%；供工業(yè)抽汽能力500噸/時，約占北京市用汽量的70%。二期擴建工程將建設兩臺30萬千瓦等級燃機“二拖一”燃氣-蒸汽聯(lián)合循環(huán)供熱機組，計劃2011年投產(chǎn)。
中國熱轉換效率最高的電廠。全廠熱效率在60%以上，比常規(guī)的凝汽式電廠的熱效率高出約20個百分點，供暖期全廠熱效率可達84%，在國內(nèi)處于領先水平。
中國第一家利用城市污水的電廠。電廠投資5000余萬元建設了二級污水系統(tǒng)，將城市污水處理后用作電廠循環(huán)冷卻水，年利用量達到1200萬立方米，相當于兩個北京頤和園昆明湖的儲水量。
中國第一家采用煙塔合一技術。脫硫效率在96%以上，二氧化硫排放濃度在50毫克/標立米以下，優(yōu)于歐洲發(fā)達國家的先進水平。宣傳冊翻譯|e-mail翻譯|電子郵件翻譯|電子宣傳冊翻譯
Foreword
Huaneng Beijing Cogeneration Power Plant pushed its way toward the clean, efficient and green development in the capital of China, in terms of the coal-fired power plant to turn “black” into “green”,
Clean and Efficient Coal-Fired Power Plant
Huaneng Beijing Cogeneration Power PlantChina Huaneng Beijing Cogeneration Power Plant lies in the east suburb of Beijing where it shoulders 10% of the power load, 70% of gas supply and 30% of the central heat supply of the city. It is the China’s first heat, power and cooling coal-fired cogeneration plant that undertakes flue gas desulfurization, denitrification, CO2 capture and urban intermediate water utilization.
China’s first coal fired power plant with CO2 capture: On Jul 16th, 2008, the first pilot project of coal-fired power plant with annual CO2 capture capacity of 3000t in China was complete and put into production, breaking the record of CO2 capture in the nation’s coal-fired power plants.
China’s power plant with the max heat capacity: Four coal-fired thermo-power cogeneration units have been installed with installed power of 845,000kW and provides a capacity of 1160 million kilocalorie/h of heat, accounting for about 30% of the capital’s central heat supply, and 500t/h of industrial extraction steam, accounting for 70% of the capital’s steam load. The expansion work in the second phase will incorporate two sets of “2-plus-1” gas-steam combined cycle generator units with 300000kW combustion engine, which expects to start production in 2011.
China’s power plant with the highest thermal conversion efficiency: The thermal efficiency across the plant is over 60%, about 20 percentage points above that of a conventional condensing power plant. The thermal efficiency across the plant can be as high as 84% during the heating season, taking the lead in China in this regard.
China’s first power plant utilizing urban sewage: More than 50 million yuan was used to invest in a secondary sewage system in the plant to treat the urban sewage and reuse it as the circulating cooling water for the plant. The annual utilization is 12 million cubic meters, which is twice as much as the storage capacity of Kunming Lake in Beijing’s Summer Palace.宣傳冊翻譯|e-mail翻譯|電子郵件翻譯|電子宣傳冊翻譯
China’s first power plant adopting chimney-tower integration technology: The desulfurization rate is over 96%, and the SO2 emission concentration is under 50mg/Ncm, which is better than the advanced level of developed European countries.
