一、未绝热的炉顶结构 通常加热炉由于结构所限,炉顶均不能绝热。这对减少炉体散热,节约能源而言是一个薄弱环节。一般在同等厚度下,炉顶的热损失要比炉墙大50％,何况炉顶砌体厚度均比炉墙小得多。因此实行炉顶的绝热就更为必要。 某厂原来未绝热的炉顶结构如图1所示。由于予制梁的顶部是配有钢筋的,所以在两根梁的中间部分不仅不能进行绝热,而且经常漏气,从而造成更大的热损失。
First, the roof structure is not insulated The furnace is usually limited by the structure, the roof can not be adiabatic. This is to reduce the heat of the furnace, saving energy is a weak link. Generally in the same thickness, the top of the heat loss is 50% larger than the furnace wall, not to mention the thickness of the furnace roof masonry walls are much smaller. Therefore, the implementation of roof insulation is even more necessary. A factory has not been insulated roof structure shown in Figure 1. Since the top of the prefabricated beam is reinforced with steel, not only the middle of the two beams can not be insulated, but often leaks, resulting in greater heat loss.
