The usage of biomass fuel for heat and power production is growing due to an increasing demand for replacing of fossil energy sources with renewable energy. Typical biomass fuel is usually a blend of different batches, for example, spruce bark and dry woodchips with varying moisture content between 30% and 55%. This varying moisture content of the fuel results in uncertainty in the energy conte...

Abstract Given the problems existing in operation of supercritical 600MW boiler, such as spiral pipe water cooling wall outlet, superheater and reheater surface overtemperature easily, amount are too large under high load, low load is small to meet need cold heating, boiler combustion optimization adjustment carried out. Through pulverized coal fineness, air distribution characteristics, swingi...

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...

-The integration of Soft Computing techniques in traditional real-time systems is a promising approach to cope with the growing complexity of real-world applications. A power station is a complicated multivariable controlled plant, which consists of boiler, turbine, generator, power network and loads. The demands being placed on Control & Instrumentation engineers include economic optimization,...

Energy saving is very important for economical and cost effective operation of the facility. In boilers, steam is produced for various process, utility and instrumental applications. It is very important to operate the boiler with proper operating conditions. The parameters like level of feed water, steam temperature and flow of steam need to be optimized. Various studies are carried out on opt...

INTRODUCTION Accurate measurement of dielectric constant and conductivity, also known as, Electrochemical Impedance Spectroscopy (EIS) is a simple, yet powerful technique for analyzing the properties of liquids and gases. EIS is currently used in a wide range of industrial applications including monitoring the purity of boiler water in power plants [1], as well as, the health of lubricants in h...
