What should I pay attention to when turning on a steam and

Gas-fired steam boilers need to install relevant requirements and regulations from opening to normal and stable operation. Parameters must not be changed at will or they are not opened and closed in order. Then what should be paid attention to when opening steam-gas boilers? What are the operating procedures? Turn on the steam and gas boiler

Oct 15, 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 …
