在以煤、柴薪为主要燃料的住宅建筑物中,按规范要求,厨房面积往往显得太小,满足不了储料(一星期)、劈柴、烧火等必要功能,为了尽可能地不突破面积指标,常在相邻两厨房的横墙内设烟囱。这种设计将烟囱与横墙溶为一体,沿墙设3个12×12cm的垂直孔洞,中间一孔直通顶层,为烟道;两边的孔称副烟道。副烟道每层分别在楼板底汇入气孔,其下口与灶室相通。此种烟道虽然净化了室内设备,但实践证明,弊多利少,主要表
In residential buildings with coal and diesel fuel as the main fuel, the kitchen area tends to be too small to meet the necessary functions of stockpiling (one week), picking firewood, and burning fire as required by the code, in order not to exceed the area index as much as possible. , often set up chimneys in the cross walls of two adjacent kitchens. This design dissolves the chimney and horizontal wall into one, and sets up three vertical holes of 12×12 cm along the wall. The middle hole passes through the top layer to form a flue; the holes on both sides are called the auxiliary flue. Each of the secondary flue gas ducts has an air hole at the bottom of the floor, and the lower mouth communicates with the stove. Although this kind of flue has purified indoor equipment, it has proved that the advantages and disadvantages are relatively few.
