Steam Hammer - The Causes And Effects of Steam Hammer
WebThis phenomenon occurs in the subcooled or low-quality region. The nucleate boiling heat flux cannot be increased indefinitely. At some value, we call it the “critical heat flux”, the steam produced can form an insulating layer over the surface, which in turn deteriorates the heat transfer coefficient. Dynamic changes of boiling regime ... WebStall occurs when the backpressure is higher than the pressure in the heat exchanger. Consider an example of process heating where a fluid is being heated using steam at certain temperature and pressure. The trap discharging the condensate will have certain backpressure at the exit against which the condensate will be discharged. shop 716 locations
