A water-wall modeling method and apparatus of supercritical once-through boilers

摘要

The water-cooled wall modeling method and apparatus. Comprising a water-cooled wall modeling method set to the (a) section tangi flow rate, pressure, and the fuel flow rate input variables fed into the furnace in the enthalpy, and the primary superheater outlet temperature at the outlet; (B) setting a flow rate, enthalpy, pressure and temperature in the water-cooled wall outlet as an output variable; (C) step of setting the density and enthalpy of the water-cooled wall in the outlet to a state variable; (D) using a steam table deriving a value of the state variable in accordance with the target temperature and the target pressure; And (e) a group a plurality of equilibrium the input change the temperature inside the water-cooled wall according to the change in the variable based on the value of the derived state variable by using the value, the pressure change value and the value of the output variable of the set water-cooled wall model and a step of calculating. ;
