mathematical model of boiler

Mathematical model of a supercritical power boiler for

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.

Mathematical modelling of transient processes in

May 11, 2007· Mathematical modelling of transient processes in convective heated surfaces of boilers. The proposed model is based on solving equation describing the energy conservation and is simplified because the mass and momentum balance equations are omitted. The suggested method considers the superheater or economizer model as one with distributed parameters.
