Design of SHL12-1.25/250-WI boiler
Abstract:     In order to consolidate, improve and enrich the knowledge of boiler principle, This design content for a SHL12-1.25/250-W I boiler. In combination with the  curriculum knowledge, this design will list the Structure layout and the Thermodynamic calculation, the ultimate goal is to master the general calculation methods and steps.
The structure of the boiler adopts the horizontal arrangement of the double boiler drum. The combustion chamber and the slag pipe is arranged as an ascending flue. The provincial gas and the air heater are arranged in a vertical flue, while Boiler furnace is full of light tube water wall. The primary criterion is the safety and reliability, and the heat transfer, combustion, smoke, air, working fluid are also under consideration. In the process of design, we need to ensure the continuous of the fire and enough radiation heat in the furnace. As the fuel the s burn ,the gas velocity and the Smoke temperature are very important. Of course, air tightness is also necessary to ensure the negative pressure combustion. In the whole process,  we need furnace, slag coagulating pipe, heater, boiler tubes, economizer, air heater of thermodynamic calculation.

We use CAD2014 to complete the picture.
Key words：thermal calculation; structure calculation
