    立式蒸汽鍋爐抑制有毒氣體

    小易為你介紹一下立式蒸汽鍋爐抑制有毒氣體

    我國幾乎所有都在進行大規模的煤制天然氣運輸。 立式蒸汽鍋爐的使用大大減少了微粒的染色,并且還抑制了諸如氮氧化物的有毒氣體的排放。 效率是垂直蒸汽鍋爐的關鍵指標,也是垂直蒸汽鍋爐效率的根本原因。 經有關部門調查后,立式蒸汽鍋爐的熱量損失可能由兩部分組成:空氣燃燒超理想,煙氣的熱量損失排出。 減少煙氣排放的熱量損失可以通過在立式蒸汽鍋爐末端進行廢氣再加熱,或使用更先進的冷凝鍋爐進行改造。

     
      空氣燃燒非常理想。 用于一般立式蒸汽鍋爐的噴射器燃燒器使得不可能操縱空燃比。 大量立式蒸汽鍋爐使用非自動供氣燃燒器,這導致空燃比不令人滿意。 空氣源比率不理想。 有兩種情況:如果有過量的氧氣,就會有無限多余的冷空氣。 加熱時,會增加立式蒸汽鍋爐的運行成本,而立式蒸汽鍋爐效率低下; 當氧氣不足時,焚燒不充分,垂直蒸汽鍋爐效率低下。
     
      如何調整蒸汽鍋爐設備的蒸汽負荷?
     

      主要是改變燃料立方體來改變蒸汽負荷。 增加燃料,蒸汽鍋爐設備增加了熱量儲存,產生更大比例的蒸汽,從而增加了負荷,減少燃料將減少蒸汽負荷。

    Xiaoyi introduces to you the suppression of poisonous gases in vertical steam boilers

    Almost all of China is carrying out large-scale transportation of coal-based natural gas. The use of vertical steam boilers greatly reduces the dyeing of particulates and also inhibits the emission of toxic gases such as nitrogen oxides. Efficiency is the key index of vertical steam boilers, and also the fundamental reason for the efficiency of vertical steam boilers. After investigation by relevant departments, the heat loss of vertical steam boilers may consist of two parts: super ideal air combustion and exhaust heat loss of flue gas. Reducing heat loss from flue gas emissions can be achieved through waste gas reheating at the end of vertical steam boilers, or by retrofitting with more advanced condensing boilers.



    Air combustion is ideal. The ejector burner used in general vertical steam boilers makes it impossible to control the air-fuel ratio. A large number of vertical steam boilers use non-automatic gas supply burners, which results in unsatisfactory air-fuel ratio. The air source ratio is not ideal. There are two situations: if there is excessive oxygen, there will be unlimited excess cold air. When heated, the operation cost of vertical steam boilers will increase, while the efficiency of vertical steam boilers is low; when oxygen is insufficient, incineration is insufficient, and the efficiency of vertical steam boilers is low.



    How to adjust the steam load of steam boiler equipment?



    The main purpose is to change the fuel cube to change the steam load. Increase fuel, steam boiler equipment increases heat storage, producing a larger proportion of steam, thereby increasing load, reducing fuel will reduce steam load.
