This paper uses the energy hub concept to meet the water, heat and electricity demand of a power plant in the Qeshm island in south of Iran. Given the power plant’s high potential for waste heat recovery and some scenarios were considered using the hub energy concept based on energy, exergy, environmental and economic analyzes in terms of meeting the demands of the hub and purchasing/selling en...

We model a steam-boiler control system using hybrid automata. We provide two abstracted linear models of the nonlinear behavior of the boiler. For each model, we de ne and verify a controller that maintains the safe operation of the boiler. The less abstract model permits the design of a more e cient controller. We also demonstrate how the tool HyTech can be used to automatically synthesize con...

This paper is concerned with calculating boiler efficiency as one of the most important types of performance measurements in any steam power plant. That has a key role in determining the overall effectiveness of the whole system within the power station. For this calculation, a Visual-Basic program was developed, and a steam power plant known as El-Khmus power plant, Libya was selected as a cas...

This paper presents an approach to analyze events leading to pluggage of a boiler. The proposed approach involves statistics, data partitioning, parameter reduction, and data mining. Two independent data mining algorithms have been applied to detect both static and dynamic relationships among the process parameters. The multi-angle data mining approach increases the ability to locate rare event...

We describe Boiler, a new software tool for compressing and querying large collections of RNA-seq alignments. Boiler discards most per-read data, keeping only a genomic coverage vector plus a few empirical distributions summarizing the alignments. Since most per-read data is discarded, storage footprint is often much smaller than that achieved by other compression tools. Despite this, the most ...

The backpressure steam turbine installations for combined production generate thermal energy and electricity. produced electricity depends on the heat load determined by consumers. Heat is released in district heating system through water, which heated with exhausted boiler-condenser (district heater). operation regime of installation influenced temperature water at input output boiler-condense...

Performance of a fuzzy system identifier is investigated against a fossil fuel boiler data. A multi-layer neuro-ftrzzy system presents identification of a drum type boiler. This identification techruque provides a rule-based approach to express the boiler dynamics in fuzzy rules that are generated from the experimental boiler data. The interconnections of neuro-fuzzy layers furnish these fuzzy ...

this paper deals with a failure investigation of boiler feed pump’s shaft of a steam power plant. boiler feed water pump is a specific type of pump used to pump, feed water into a steam boiler and is one of most important part of steam power plants. feed pumps failure may cause failure of another part of steam power station, therefore keep them safe is an important problem. there are 12 feed pu...

This article describes the rationale for development of a mathematical model thermal scheme Vladivostok power plant. Four types turbines are installed at this plant, boiler units operate on coal and natural gas. makes it difficult to effective load distribution between turbine units. Application simplified dependencies, built basis reporting data, allows analyse correctness The provides an exam...
