| Abstract: | Abstract:This paper developes a heating coefficient model to study the heating performance of multi-nozzle water-jet steam ejector. It analyzes the factors of heating performance, and explores the relationships between the heating performance and different operating parameters theoretically and experimentally. The results show that the heating performance of multi-nozzle water-jet steam ejector is very good. The heating coefficient decreases with the increase of the inlet water temperature, and increases with the increase of the steam pressure and ejecting coefficient. The relationships between heating performance of ejector and different operating parameters by calculation and experiment are in good agreement. |
