boiler system


The boiler system is made up of:
Makeup water which is the raw water which must come from outside the boiler room and plant processes. The steam system collects and controls the steam produced in the boiler. Steam is directed through a piping system to the point of use.

The Pulverize is a major part of the boiler combustion system and an important part in the system of steam power plant (PLTU). Pulverizer plant serves to break chunks of coal into the coal ash was then fed to the burner. Type of feed coal into a pulverize is cleaned with a

Automatically verifying an object-oriented specification of the steam- boiler system
free download

Correctness is a desired property of industrial software systems. Although the employment of formal methods and their verification techniques in embedded realtime systems has started to be a common practice, the same cannot be said about object-oriented software. This

Passive fuzzy controller design for perturbed nonlinear drum- boiler system with multiplicative noise

Nonlinear adaptive control based on parameter identification for a boiler system
free download

It is well-recognized that in real practices, some or even all of the parameters for a well- defined model are subject to change due to the following reasons:(1) it is difficult to construct an exact model for the boiler system because of its complexities; and (2) even if an exact

ROBUST MIXED H_2/Passivity PERFORMANCE CONTROLLER DESIGN FOR UNCERTAIN DRUM- BOILER SYSTEM
free download

This paper discusses a robust control problem of uncertain drum- boiler system subject to H2 and passivity performances. The main aims of H2 control scheme are to minimize output energy and guarantee robust asymptotical stability. Besides, passivity theory is applied to
