This paper describes a systematic approach to predict the water level in the drum of a steam boiler with the help of artificial neural networks (ANN). The parameters of the model can be obtained from the physical dimensions and characteristics of the boiler. The frequency of deviations and the degree of deviation of the water level in the drum can be significantly reduced by the ANN modeling of...

In order to improve the performance properties, in particular viscosity-temperature, of boiler fuel, it is proposed combine them with narrow fuel fractions obtained by thermal destruction secondary polymer raw materials (low pressure polyethylene and polypropylene).
 When compounding grade 100 oil fractions, values ​​of density are reduced 865 (873) kg / m3, conditional viscosity 2.50 (2.6...

A Data Analysis System for Industrial and Enterprise Greenhouse Gas Emission, for meeting the needs of the giant energy-consuming enterprises has been set up through a series of studies on the verification method of Greenhouse Gas (GHG) in industries such as cement, thermal power, cogeneration, transport, sewage treatment etc. The analysis system consists of six modules: Organization Structure;...

Abstract This paper presents an algorithm for generating association rules from a given large database consisting of inputs and outputs of a 330 MW coalfired thermal power plant. The input parameters include fuel properties, operational parameters of the boiler, and the conditions on the stack. The outputs include emissions and heat losses along with the thermal efficiency of the power plant. T...

Measurement of thermal conductivity of rocks is important to understand the thermal properties of earth materials, the characteristics of terrestrial heat flow, and the formation of oil. In this paper we report thermal conductivity, thermal diffusivity, and heat capacity data for 12 conglomerate, sandstone, and gypsum-bearing samples from the Paleogene Kuqa River profile in Kuqa, China. Samples...

Major furnace explosions have resulted in the deaths of personnel, extremely expensive repair costs and, in most cases, loss of revenue during the repair period. For a large power station boiler the total cost of a furnace explosion could easily be in the $10M to $20M range. The protection systems fitted to a modern boiler have been developed to the stage where boiler explosions are a rare occu...

This paper describes a prototype instrumentation system for photogrammetric measuring of bed and ash layers, as well as for flying particle detection and pursuit using a single device (CCD) web camera. The system was designed to obtain images of the combustion process in the interior of a domestic boiler. It includes a cooling system, needed because of the high temperatures in the combustion ch...

Our world and every person require a huge amount of energy, both electric thermal, which are produced mainly at various types power plants, but mostly on thermal. During the production electricity heat thermal plants different potential hazards occurring: chemical, environmental, fire or explosion. In accordance with identified possible six emergency situation scenarios suggested. The failure t...

There is strong observational evidence that a quasi-thermal population of electrons (or pairs) exists in compact X-ray sources. It is, however, unclear what mechanism thermalizes the particles. Here, two processes, Coulomb scattering and synchrotron self-absorption, that may be responsible for the thermalization, are reviewed. The parameter spaces in which respective process dominates are given...

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...
