D88尊龙I. Gas-fired Internal Combustion Engine Power Generation System

優點:熱效率較高;構造緊湊、重量輕,適于挪動;啟動便當;可選功率范圍寬;對瓦斯濃度順應性強;

Advantages: high thermal efficiency; compact structure, light weight, suitable for moving; easy start; wide range of optional power; strong compliance with gas concentration;

D88尊龙缺陷:構造復雜,噪音大;熄滅不完整,廢氣中CH、CO、NOX 等污染物含量較高;

Defects: Complex structure, high noise, incomplete quenching, high content of CH, CO, NOX and other pollutants in exhaust gas;

二、燃氣輪機發電系統

II. Gas Turbine Power Generation System

D88尊龙優點:構造簡單、緊湊,運轉維護便當;單機功率大;啟動快捷、運轉平穩;毛病率低、自動化水平高;

Advantages: simple structure, compact, convenient operation and maintenance; high single-machine power; fast start-up, smooth operation; low defect rate, high automation level;

缺陷:小型燃氣輪機價錢昂貴,效率小,對瓦斯濃度請求較高40%以上;

Defects: Small gas turbines are expensive, inefficient and require more than 40% higher gas concentration.

三、蒸汽輪機發電系統

3. Steam Turbine Power Generation System

優點:較好的應用余熱;技術較為成熟,主要用于結合循環發電;

Advantages: better application of waste heat; more mature technology, mainly used for combined cycle power generation;

缺陷:設備龐大、復雜不能挪動;初投資大,低負荷運轉時效率低;對瓦斯濃度請求高30%以上;

D88尊龙Defects: the equipment is huge, complex and can not be moved; the initial investment is large, the efficiency of low-load operation is low; the request for gas concentration is higher than 30%;

四、熱電聯產

D88尊龙IV. Cogeneration of Heat and Power

優點:熱效率高、污染小、環境代價低;節約用水、占地儉省、設備靈敏;

Advantages: high thermal efficiency, low pollution, low environmental cost, water saving, land saving, sensitive equipment;

D88尊龙缺陷:僅適用于大型電站 ;

D88尊龙Defects: Only suitable for large-scale power plants;

五、混合熄滅

V. Mixed extinction

優點:減少 SO2、NOX 的排放;減少純燃煤時的結垢;投資少, 技術風險小;

D88尊龙Advantages: reduce SO2, NOX emissions; reduce scaling when burning pure coal; less investment, less technical risk;

缺陷:對水質請求高;鍋爐的功率必需足夠大僅適用于大型電站;

Defects: High requirement for water quality; Boiler power must be large enough for large power plants only;
