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 value product pulverize optimum 30%. The percentage of this value greatly affects the production of steam in the boiler. Th...

Due to the important role of the boiler-turbine units in industries and electricity generation, it is important to diagnose different types of faults in different parts of boiler-turbine system. Different parts of a boiler-turbine system like the sensor or actuator or plant can be affected by various types of faults. In this paper, the effects of the occurrence of faults on the actuators are in...

Property-oriented testing uses the specification of a property to drive the testing process. The aim is to validate a program with respect to a target property, that is, to exercise the program and observe whether the property is violated or not. We define a test strategy for safety properties in cyclic control systems. It consists of the stepwise construction of test scenarios. Each step explo...

The product of corrosion in the feed water system transported into the boiler and gets deposited on the internal surface of waterwall tubes. Proper treatment of boiler feedwater effectively protects against corrosion of feedwater heaters, economizers, and deaerators. It leads to overheating and on-load corrosion and ultimately tube failure.. Heat is transferred through a thin layer of superheat...

Combustion optimization adjustment can effectively suppress NOx emissions from power plant boilers. Current combustion optimization adjustment methods involve nonlinear optimization based on the boiler combustion model, such as optimization by a genetic algorithm or particle swarm algorithm. The computational complexity of these methods results in poor real-time performance, which limits their ...

Every six months or so the majority of steamdriven ships spend a few days in docks having their boilers scaled and cleaned. In the larger docks there are men who are employed full time in this occupation, but elsewhere and in industry generally the cleaning is more often done as an occasional job. The total number of men engaged in the work full time is not large, but the occupation is a very d...

Wall thinning due to corrosion in utility boiler waterwall tubing is a significant operational concern for boiler operators. Historically, conventional ultrasonics has been used for inspection of these tubes. Unfortunately, ultrasonic inspection is very manpower intense and slow. Therefore, thickness measurements are typically taken over a relatively small percentage of the total boiler wall an...

This paper presents a system specification of the steam boiler control system described in [?]: To manage complexity and to foster separation of concerns the design model is divided into three views: The architectural view specified with object and class diagrams, the reactive view specified with statecharts, and the functional view specified with Z. A systematic relationship between the reacti...

This paper is constructed with the effort of development of controlled system on the application of a traditional Zeigler-Nichols (Z-N) tuning method implemented for a boiler-turbine power plant to achieve better efficiency of the system. Extensive study and analysis of the state space representation to mathematical modeling approach is developed for the system introducing simulation method. A ...
