Heat transfer coefficient calculation
Thread Content
Dear experts, is there any information available for sharing regarding the calculation of the heat transfer coefficient of flue gas condensation heat exchangers?
Gas-to-gas heat exchange or gas-liquid heat exchange?
Gas-liquid heat exchange, that is, flue gas and cooling water:)
Just provide the parameters, and it will be fine after designing it
The components of the flue gas, flow rate, temperature, water temperature – these values need to be provided; the calculation is relatively simple
The saturated flue gas volume is 1,173,185 Nm3/h; the inlet temperature of the flue gas is 51°C, with a required outlet temperature of 44°C. The inlet temperature of the cooling water is 20°C, and the required outlet temperature is 30°C. The heat exchange tubes are titanium tubes with a diameter of φ25×1.5. How is the overall heat transfer coefficient generally calculated, or are empirical values used?
The heat exchange tubes can be φ10×1 fluoroplastic tubes
Send us the parameters and our company will carry out professional design and manufacturing of such heat exchangers.
50~90W/(m2.OC)
This cannot be shared; it is necessary to examine the composition of the smoke, and then calculate the physical properties of that smoke in order to carry out thermal calculations. Coal with different calorific values and boilers with different compositions must be different, right?
