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...

According to the recent European guide lines concerning the smart grids, the generation of electricity and heat from poultry derived wastes based on hightemperature thermal destruction techniques, i.e. combustion, could be a promising local waste management solution [1-5]. In this work we set out to investigate the technical and the economic feasibility of the combustion of poultry litter blend...

Abstract Supercritical boiler system has been widely used to increase efficiency of electricity generation in power plant industries. However, the supercritical operating condition can seriously affect structural integrity components due high temperature that causes degradation material properties. Pressure reducing valve is an important component being employed within a main steam line boiler,...

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...

Livestock farms are a major contributor to CO2 emissions. The use of renewable energy sources (RES) is an important step mitigate emissions from farms. This paper develops and evaluates market-integrated, cost-effective, case-sensitive RES solution for livestock For this purpose, the dairy farm at LVAT-ATB in Germany; which includes three barns milk production with total area 3950 m2, was consi...
