본 발명에 따라 고온 물질의 통로 아래에 배열된 열 차폐용 패널(4)은 한정된 움직임이 허용되도록 지지된다. 각각의 패널의 양단부에 위치한 버팀용 바아(10)는 또한 이동 가능하게 장착되어 패널 아래에 놓이게 되는 지지용 요소(20)를 구비한다. 버팀용 바아는 뒤틀린 물질에 의해 부딪히게 될때 순간적으로 이동할 수 있게되며, 패널과 함께 상기 지지용 요소의 지지식 맞물림을 통해 또한 패널의 이동이 일어나기 때문에 흐트진 침전물을 패널의 상부면(4c)위로 교란시키게 된다. 따라서, 패널의 간헐적인 교란은 피동적으로 발생하며 패널의 상부면상에 적층된 침전물은 상부면의 경사각 감소를 허용할 수 있도록 조정될 수 있다. The heat shield panel 4 arranged under the passage of the hot material according to the invention is supported to allow a limited movement. Bracing bars 10 located at both ends of each panel also have a support element 20 which is movably mounted to be placed under the panel. The prop bar can move instantaneously when it is hit by warped material, and the displaced sediment above the top surface 4c of the panel because the movement of the panel also occurs through the supportive engagement of the supporting element with the panel. It is disturbed. Thus, intermittent disturbances of the panel occur passively and deposits deposited on the top surface of the panel can be adjusted to allow for reduction of the tilt angle of the top surface.
