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...

The title of the paper purports to discuss the feasibility of 100% RDF firing for power generation. It is implied that it is possible to fire 100% RDF in a single boiler. However, for the case study cited, the author suggests a much more elaborate system for a 16 MW system. The flow sheet suggests 80% heat input from RDF and 20% from coal. He also suggests that three boilers handle the RDF. Thi...

Article history: Received October 15, 2011 Accepted 10 March 2012 Available online 12 March 2012 The recent development of world is being adversely affected by the scarcity of power and energy. To survive in the next generation, it is thus necessary to explore the non-conventional energy sources and efficiently consume the available sources. For efficient exploitation of the existing energy sou...

Abstract: The paper presents the research results related to control of the steam boiler parameters: drum level, furnace pressure and steam pressure. It was developed the mathematical model of the water-steam system and furnace part of the boiler. Also, the paper presents the algorithm for real time detection of model parameter variations. In this context a correction method, validate through s...

Cement production is an energy-intensive process, so that the cement industry occupies a top position among other energy-consuming industries. Among the equipment used in cement industries, boilers are one of the energy-consuming equipment. Boilers are among the common heating equipment in industrial, commercial, and institutional facilities. In this paper, the performance of thermal oil bo...

SPIN is a tool for the simulation and veriication of protocols. PROMELA, its source language, is a formal description technique like SDL and Estelle that is based on communicating state machines. The tool and the language are in the public domain and therefore widely used. The "Steam-Boiler Control Speciication Problem" consists of an informal speciication of a steam boiler system in a nuclear ...
