Influence of increased primary air ratio on boiler …

1/6/2018 · Hence, the effects of PA/PC temperature on coal combustion behavior and boiler performance were examined before the influence of PAR was conducted. As shown in Table 5, with PA/PC temperature increasing from 328 K to 343 K, the flue gas temperature at the hypothetical furnace exit increases about 0.32% while the concentration of unburned char particles (UCPs) decreases by 0.74%.

15/10/2019 · In the present work, the overall behavior of a steam boiler is investigated using RELAP5/MOD3.2 system code at three different operating loads. Main thermal–hydraulic parameters are analyzed at steady-states corresponding to 60%, and 110% of the boiler nominal load. RELAP5 system code is widely used in the design and safety analysis of nuclear reactor installations as well as …
