一、设计原理:回风灶是根据燃料燃烧过程中的热量分布,被加热物体吸热后热又二次利用设计的:即充分利用烟道余热,又减少排放热量。二、制作过程1.材料选配。采用黄砂、煤碴、水泥三种材料按照1:2:1配比加水拌和,使至手捏成团不出水为宜。2.模制成型。将拌好的料分别装入模内捣固密实,加水保养一周即成。3.分解模制成型。回风灶的烟道制作较难,为使烟道符合设计规格,又能马上脱模,因此一次成型是不易做到的。我们采用
First, the design principles: Back to the stove is based on the distribution of heat in the fuel combustion process, the object was heated after absorbing heat and re-use of the second design: that is, make full use of flue heat, but also reduce emissions. Second, the production process 1 material matching. The use of yellow sand, coal ballast, cement three materials in accordance with the ratio of 1: 2: 1 with water mixing, so that the hand into the group is not suitable for water. Molding. Will be mixed with the material into the mold tamping dense, add water to maintain a week Serve. 3 decomposition molding. It is harder to make the flue of the return air stove, so that the flue can meet the design specifications and can be demolded immediately. Therefore, it is not easy to mold once. We use
