Modelling of systems is very much useful to study the response of a system for different input variations and for the design of control schemes in both real time application and in the off-line simulation. The development of optimized fuzzy model for a boiler superheater of a 210 MW coal fired thermal boiler power plant is reported in this paper. The fuzzy model has been developed first taking ...

This investigation has been undertaken to better understand pollutant formation in Waste-to-Energy (WTE) systems by using Computation Fluid Dynamics (CFD). An above-grate gas phase only model was built and calculated in FLUENTTM with the intent of specifically studying the factors that influence the formation of NOx. Results are shown for a typical reciprocating-grate WTE boiler operating on mu...

The autonomous energetic system is for a residential building and it has as primary sources exclusively renewable resources (biomass and solar energy). For obtaining electrical energy, photovoltaic sources and a Stirling engine are used. They operate simultaneously in 1:3 ratio – electrical/thermal energy. Solar collectors and a pellet boiler are used to cover the necessary of thermal energy. T...

biomass co-firing with lignite represents an attractive solution for operating lignite-fired thermalpower plants (tpp) with the dual advantage of using local renewable resources and simultaneously reducingemissions. the subject of this study is technical and environmental investigation of the feasibility of the cofiring of soma lignite with some dried agricultural residues in the soma thermal p...

In this paper an attempt has been made to develop an expert system called VIBMASTER to help the plant maintenance persons in diagnosing the cause of excessive vibration at the bearing supports of a rotating machinery. In the expert system a data base has been compiled from Standards, Journals, Handbooks and Rules from Maintenance Manuals related to maintenance engineering and management. The tr...

The main sources of anthropogenic emissions into the atmosphere Murmansk are from thermal power plants and boiler houses operating on fuel oil. As a result analysis dynamics pollutant stationary for period 1997-2019 it has been established that level air pollution is assessed as low; there tendency towards decrease in gross sources. pollutants sulfur dioxide, nitrogen oxides, carbon monoxide, f...

A black liquor recovery boiler has two main functions. On one hand, it generates steam from the heat energy liberated upon combustion of the organic constituents of black liquor burned in the boiler, whereby the recovery boiler serves as a steam boiler. On the other hand, the chemicals from pulp digesting sulphur and sodium are recovered from the black liquor, the recovery boiler then serving a...
