In all types of chemical Industries/ Star Hotels/ Hospitals, boiler is a important process unit. Mainly steam boilers are needed. Steam as means of direct or indirect heating, system as a raw material, steam as a means of generating electricity. The management of a boiler’s operation conditions is an obvious necessity. If we take into account that the excessive working parameters are the main hazardous problems because of the risk explosion. Boiler nominal state and to control them is difficult task because a steam boiler is a very complier system in which all the elements are connected. It is very difficult to carry out test directly on a boiler, both from the technical point of view dangerous derived from manipulating the operating and the economic point of view. Taking this into consideration we have to be look for an alternative method of analysis by simulation modules.
