In the paper performance of the prototype design of the condensation hood is analysed. Results of some experiments/measurements as well as results of CFD simulations are used to investigate the dependence of quantity called the condensation efficiency on selected working parameters. It was found that both the air inlet temperature and the air mass flow rate have significant impact on the performance of the heat exchanger. However, such changes did not influence the condensation efficiency which stays stable at the level of 100% for quite wide range of parameters changes. The same applies to the relative humidity of the inlet air. The only parameter which causes changes of the condensation efficiency is the steam mass flow rate when it exceeds 2.0 g/s. Nevertheless, operation of the hood with the steam mass flow rate up to ≈ 3.0 g/s guarantees that at least 90% of the steam is condensed. [ABSTRACT FROM AUTHOR] |
