Embodiment 1
[0054] Suppose the amount of red coke processed per day is ; The amount of medium-pressure steam produced at 450°C and 4.6Mpa is ; Specific enthalpy of medium pressure steam at 450°C and 4.6Mpa and specific entropy ;Enthalpy value of boiler feed water at 105℃ and specific entropy ; Enthalpy of water in boiler at 256°C and specific entropy ;Enthalpy of red coke at 1050℃ and entropy ; Enthalpy of coke at 180°C at CDQ outlet and entropy ; Specific enthalpy of coke combustion ; The proportion of boiler blowdown is ;system fire The coefficient of loss is ; The amount of steam leaked from the boiler . For specific parameter selection, please refer to "Practical Handbook of New Technologies and Standards for Installation and Maintenance of Coking Equipment" edited by Wang Xiaodong (Heilongjiang Cultural Audiovisual Publishing House, 2004 edition). Into the formula:
[0055]
[0056] The burning loss rate obtained by reliable calculation is 2.2%. Und...
