        冷凝式鍋爐首先應用于西方發達國家,世界上首臺冷凝式鍋爐出現于二十世紀70年代誕生于荷蘭,得益于其在實際使用中凸顯的節能及環保效益,冷凝式鍋爐在北美和歐洲得到了迅速的發展。目前荷蘭和瑞士的冷凝式鍋爐普及率為70%,德國30%,奧地利30%,英國25%,而亞洲國家中韓國的冷凝式鍋爐發展最快,普及率最高。隨著我國經濟發展和能源消耗的提高以及對環保問題的日益重視,高效節能技術和清潔能源的利用顯得尤為重要。

         

            云天鍋爐通過對鍋爐熱損失的剖析,深入研究了鍋爐排煙溫度與鍋爐熱效率的關系,研發了WNS系列冷凝式燃油(氣)鍋爐。通過大量實驗得出了鍋爐排煙熱損失與排煙溫度、過量空氣系數、燃燒用空氣濕度及溫度的關系曲線。通過合理布置受熱面,優化鍋爐背壓的方式,充分利用高溫煙氣中的顯熱和煙氣中水蒸氣的汽化潛熱加熱鍋爐給水或鍋爐燃燒用空氣,從而顯著提高鍋爐熱效率。

         

        Condensing boiler was first applied in the western developed countries.The first condensing boiler in the world  appea red  in  Nether[andsin the 1970s. Benefiting from the energy saving and environmentalprotection which are highlighted in its practical use, condensing boilerhas gotten ra pid deveiopment in North America and Eu rope. At present,the penetration rate of condensing boilers is70% in Netherlands andSwitzerland, 30% in Germany, 30% in Austria and 25% in British.However, condensing boilers have the fastest growing and the highestpenetration rate in some Asia countries such as South Korea and China.Along with the economic development of our country, the improvementof energy consumption and more and more attention to the problemsof environmental protection, the utitization of high efficiency energysaving technology and  clean energy is  pa rticu[arly important. Th roughthe anaiysis of the heat loss of boilers, Yuntian Boiler deeply studieson the relationship between the boiler exhaust temperatu re and thethermal efficiency of the boiler, and developsWNS series condensingfuel oi[ (gas) boilers. The relation curves between the heat Ioss ofthe boiler exhaust and the exhaust temperatu re, the coefficient ofthe excess air and air humidity and temperature for combustion areobtained t:hrough experiments. The thermal efficiency of boiiers isimproved th rough  reasonable decorations of heating su rface, theoptimization of the back pressure of boilers, making full use of theexplicit heat in high temperatu re flue gas and iatent heat of vaporizationof water vapor in flue gas to provide water for the heating boiler or gas
        for the combustion.
