Mr. Nowak's paper finally puts European incinera­ tor practice in its proper perspective. It is interest­ ing to note that incineration is selected for the dis­ posal of refuse for the same reasons in his country that are usually used in our country. Perhaps the decision to generate steam from refuse in this country will follow thei r decision process. Mr. Nowak has pointed out that burning ref...

Sludge is one of the main pollutants from sewage treatment and contains a high content water organic matter. The co-combustion sludge coal can bring about energy conversion sludge. However, moisture in inorganic generated by have adverse effects on combustion environment. In this work, through experimentation, it was demonstrated that does not release obvious toxic elements or create an environ...

The values of reaction forces in the boiler supports are the basis for the dimensioning of bearing steel structure of steam boiler. In this paper, the application of the method of equivalent stiffness of membrane wall is proposed for the calculation of reaction forces. The method of equalizing displacement, as the method of homogenization of membrane wall stiffness, was applied. On the example ...

Abstract: In this paper, we analyze the exergy costs of a real large industrial boiler with the aim of improving efficiency. Specifically, the 350-MW front-fired, natural circulation, single reheat and balanced draft coal-fired boiler forms part of a 1050-MW conventional power plant located in Spain. We start with a diagram of the power plant, followed by a formulation of the exergy cost alloca...

This document describes the motivations for and the effects of cofiring biomass with pulverized coal (pc) in pc-fired boilers. Such cofiring represents a near-term, low-risk, low-cost option for reducing the net CO2 emissions from the power generation sector. This document focuses on four of the critical fireside issues associated with cofiring: ash deposition, NOx production, corrosion, and ca...

Graphical representation is useful to illustrate complex structure in a direct or intuitive way. A graph is a symbolic of network and its connectivity can be simplified as a set of linked notes. In recent studies of complex control system, directed graph has been introduced to define and interpret the interconnection structure underlying the dynamics of the interacting subsystem. Generally, the...

Increasing world-wide energy use and growing population growth presents a critical need for enhanced energy efficiency and sustainability. One method to address this issue is via waste heat scavenging. In this approach, thermal energy that is normally expelled to the environment is transferred to a secondary device to produce useful power output. This paper investigates a novel MEMS-based boile...
