Heat Transfer Coefficient Estimation and Performance Evaluation of Shell and Tube Heat Exchanger Using Flue Gas

In the past few decades, water and air were commonly used as working fluid to evaluate shell tube heat exchanger (STHE) performance. This study was undertaken estimate transfer coefficients performance in pilot-scale twisted tube-based STHE using flue gas from biomass co-combustion fluid. Theoretical calculation along with experimental results calculate specific of gas. A simplified model then developed integration two methods predict overall coefficient without tedious individual fouling factors. Performance including trailer temperature, load, effectiveness, jointly investigated under variable operating conditions. Results indicated that ranging between 1.044 1.338 kJ/kg·K while increased by increasing temperature decreasing excess ratio. The mathematical validated have relatively small errors coefficient. mass flow rate 61.3–98.8 kg/h, a 13.7–14.1 L/min, parallel arrangement water-to-air heaters an empty found be optimal conditions for space heating purpose. addition, lower poultry litter feeding decreased loss gain water, also provided maximum possible higher actual quickly achieve equilibrium ultimately improves demonstrates possibility collecting residual system outlining systematic approach process evaluating its
