目前,炕面普遍使用的材料是砖和土坯,以热性能的要求看还是可以的,但由于砖的面积小,在布置炕洞时要受到炕洞支承点的限制,使传热和烟气流动受到干扰。为此,在今后推广新式炕时,应选用导热快而蓄热多的材料。从表中可以看出,导热快,蓄热多为石板,其次为混凝土水泥板。但从炕的结构发 At present, the commonly used materials on the kang surface are bricks and adobe, which can be seen by the requirements of the thermal performance. However, due to the small area of ​​the bricks, the kang hole needs to be limited when the kong hole is arranged so that heat transfer and flue gas Flow disturbed. To this end, in the future promotion of new kang, heat should be used quickly and heat storage materials. As can be seen from the table, thermal conduction, heat storage and more for the stone, followed by concrete cement board. However, the structure from the kang hair
