Based on energy conservation equation and mass conservation equation

through introducing the idea of modularization into modelling

a dynamic numerical model for emulation study on utility boilers has been established by using the mechanism modelling method

and an algorithms-library being built on the platform of Matlab/Simulink software integrated with CMEX S-function

S-Function module

Memory module

and module packaging etc. as basic methods. Application shows that the developed systematic emulation algoriths-library has all necessary modules

boasting strong universality

being convenient in use

having better expansibility and continuity

being easily extended and applied to study the control systems.
