The heat sensitivity coefficient of water-wall with vertical pipe-loops in supercritical CFB boilers has been quantitatively calculated
the infuence of parameters
such as the dryness
the mass flow speed
and the pressure etc.upon the heat sensitivity of water-wall in the boiler being analysed.The temperature deviation and enthalpy deviation at outlet of the water-wall under different boiler load have been calculated
the calculation shows that the temperature deviation on water-wall in supercritical CFB boiler with 30% increament of heat flux density on its water-wall is far lower than that of supercritical pulverized coal boiler with 10% increament of heat flux density on its water-wall.
