Process Design of Waste Heat Recovery in Continuous Blowdown of Steam Boiler Based on MATLAB Software |
| |
| Abstract: | An energy-saving scheme is proposed to solve the waste heat and water resources in continuous blowdown of steam boiler. Matlab software is utilized to design calculation program for heat exchanger in heat recovery of steam boiler's continuous blowdown because of the complex problems in heat recovery design. Iterative methods are applied to obtain the heat gain of the deaerated water tank and softened water tank respectively. The heat exchange area of heat exchanger is calculated and investigated in different ways in the process of the waste heat recovery. The optimal plan for calculating heat exchange area is selected with comparison and analysis. The energy saving effect of the continuous waste heat recovery scheme for steam boiler is analyzed and calculated. |
