Reference of the industrial boiler operation experience for reference, and the advantages of similar products on the basis of design, the product as double horizontal cylinder decorate natural cycle pot along the converter row structure. This boiler for low pressure, double the transverse layout, natural cycle tube bustion equipment, steel frame fixed, is add coal scuttle and turn scale not leak chain grate coal. Be full of water-wall tubes all round chamber, the exit layout of the furnace slag tube. The sparse Still lying between the cylinder and densely layout of the convection over. The boiler in shaft layout cast iron economizer and tube type air preheater. Stoker deceleration machine adopts stepless change. The double boiler installation way of operation for zero meters layer elevation. The main design content includes: 1, determine the boiler general pattern. 2. The structure of boiler design and thermodynamic calculation. 3. Local radiation heating water circulation of calculation. 4. Pot tube strength design and strength calculation. In this paper, the design of the boiler in meet the load demand, and on the basis of considering the maximum level of technical and economic demands KEY WORDS : Steam boiler, thermodynamic calculation, natural circulation, pot tube strength 青岛理工大学毕业设计(论文)用纸 3 目录前言........................................................................................................................................... 1 第1章锅炉设计资料....................................................
