  1. There are a lot of advantages when inner trachea applied in air pre - heater, such as the improvement of the temperature of pipe, the low consumption of metal, except for the increment of flow resistance. according to many related papers, it is more proper inner trachea with the structure of short distant between two whorls and shallow depth of whorl. it can enhance heat transfer with smaller flow loss

    內螺紋管是一種異形管,和光管相比,管內側的換系數大大增強了,應用於空氣預可以起到提高總系數、節約受面金屬消耗量的目的;同時提高了管溫度,能夠減輕低溫腐蝕的程度和速度;不足之處是帶來了更大的阻力
  2. Taking some tubular air pre - heater used in one boiler whose capacity is 130 t / h as an example, new blue print with inner trachea is completed by means of computer program. several key design variables may be changed, such as diameter of pipe and velocity of flow of gas. these cases have been considered, and their results have also been compared with each other
