Design issues of waste heat boilers
Thread Content
The rated saturated steam output is 4 t/h, with a pressure of 0.5 MPA. The inlet and outlet temperatures of the flue gas are 640 and 165 respectively. The treatment capacity is 5000 m3/h. The temperature of the cooling circulating water is 140, while the temperature of the superheated steam is 161. How should the mixed flue gas be calculated? Should it be based on heat?
What is the flue gas volume? Regular smoke?
For the mixed flue gas of CO2, O2, N2, and H2O, the average molecular weight was calculated to be 30. I used a calculation website to determine the thermodynamic parameters, but I’m not sure how to proceed with further calculations
