A new mathematical model is developed to simulate the BP-2450 boiler dynamics. The boiler is currently under construction in one of the Polish power plants. The developed models of the boiler heating surfaces (the evaporator, steam superheaters, and reheaters, feedwater heater, SCR reactor, and RAH) are considered as a distributed parameter models.
