1. A boiler using an enhanced heat transfer element comprises a boiler shell or a water pipe, a hearth or/and a hot flue gas channel and a working medium;

  • the method is characterized in that;

    the boiler shell or the water pipe wall separates the hearth or/and the hot flue gas channel from the working medium and transfers the heat in the hearth or/and the hot flue gas channel to the working medium;

    the single surface or double surfaces of the boiler shell or the water pipe wall are provided with boss-shaped enhanced heat transfer members made of high-heat-conductivity materials, and the enhanced heat transfer members are densely distributed with mutually communicated small holes from the outer surface to the inner part;

    the cross section of the reinforced heat transfer element is circular or square, the cross section area of the top of the appearance of the reinforced heat transfer element is smaller than the cross section area of the bottom, the angle between the geometric center line of the top of the appearance of the reinforced heat transfer element and the cross section of the bottom of the reinforced heat transfer element is smaller than 90 degrees, and a cavity which is opened towards the same direction is formed in the reinforced heat transfer element.
