摘要：本文是設計DZS2-1.0-Q型燃氣蒸汽鍋爐。設計中首先已知鍋爐參數，如鍋爐的蒸發量為2。根據設計范圍，首先進行鍋爐的燃料與燃燒計算。燃料與燃燒計算包括理論空氣與理論煙氣容積的計算，煙氣焓溫表以及鍋爐熱平衡及燃料消耗量的計算, 計算得出燃料消耗量為368.2 ,鍋爐效率為89.28%，選擇了國產火神全自動控制燃燒器的AW型杯轉式自動燃燒器。給出爐膽尺寸和螺紋管束標準。進行鍋爐的爐膛和對流受熱面的計算，其后確定了其他主要部件的尺寸并進行熱力計算。其中主要是對流管束的結構和熱力計算。在這些基礎上，又進行了鍋爐的爐膽、零件的強度校核計算,提高鍋爐運行的安全性。從而得出結論，設計的鍋爐是可行的。

Abstract: This article is to design steam boiler DZS1-1.0-Q .The first step of tile is to calculate the fuel and the combustion base on the Boiler parameters and the Design standard., fuel consumption is calculated as 368.2 m3 / h, the boiler efficiency is 89.28%.we select the burner, which determine the type and size of furnace, including the conical furnace , flat corrugated furnace and furnace. The forth is determining the size of other major components and making thermal calculation.The calculation of the fuel and combustion include calculation of Theoretical air and Theoretical gas ,the volume of the gas, fuel consumption calculation and thermal balance of the boiler. Select the furnace size, the standard of screw bundle base on the Combustion calculations. And then doing the calculation of the surface and the convection heating surface. The heat calculation of convection heating surface include the structure of convection bundle and the thermal calculations. In this basis, the boiler's furnace tube, part of the strength check is calculated to improve the safety of boiler operation. Thus, concluded that the design of the boiler is feasible.
