The fast pyrolysis process is developed to produce liquid bio oil from biomass. In the discussed process the required thermal energy is extracted from a circulating fluidized bed boiler (CFB) as hot sand fed into the pyrolysis reactor. Residual char and uncondensed gases from the pyrolysis process are fed back and combusted in the boiler. Thus, the pyrolysis and the boiler processes are interco...

The use of boiler wood-fired is fairly common equipment utilized in steam generation for energy production in small industries. The boiler activities are considered dangerous and heavy, mainly due to risks of explosions and the lack of mechanization of the process. This study assessed the burden of physical labor that operators of boilers are subjected during the workday. Assessment of these co...

In March 2008, Keppel Seghers started the engineering, supply, construction and commissioning of a Combined Heat and Power (CHP) Waste-to-Energy (WtE) plant in Åmotfors (Sweden). When completed in 2010 the plant will process close to 74,000 tons per year of household waste (average LHV = 10.5 MJ/kg) and limited quantities of (demolition) wood resulting in a yearly production of about 108,700 MW...

Waste heat boiler will be restricted by the exhaust parameters of gas turbine, at same time, it affect thermal characteristics steam side, and its flue resistance directly power efficiency turbine cycle, which have an important impact on combined cycle system. Therefore, is necessary to monitor running status equipment in identify early signs faults, make accurate judgments fault location, degr...

Renewable energy is becoming widely used all over the world nowadays. More single-family houses use such sources to generate heat and electricity. The article presents a case study of house located in central Poland, which photovoltaic system was used, additionally with other renewable sources, as small wind turbine, biomass boiler solar panels. describes advantages using building sector consid...

The rigorous development and veri cation of a boiler system speci cation is presented. Part I shows how the boiler system controller can be developed in a series of elaboration steps in which variables that directly re ect plant conditions are replaced by variables representing sensed, communicated values. Part II shows how the safety of the system can be assessed by rst verifying safety relati...

This paper presents an approach to control pluggage of a coal-fired boiler. The proposed approach involves statistics, data partitioning, parameter reduction, and data mining. The proposed approach was tested on a 750 MW commercial coal-fired boiler affected with a fouling problem that leads to boiler pluggage that causes unscheduled shutdowns. The rare-event detection approach presented in the...

The paper deals with steam flow in experimental turbine T10MW, located Škoda laboratory. was examined for low or negative outputs of the turbine, i.e. so called last stages ventilation. path Boiler Feed Pump Turbine (BFPT) version. It had all together 4 out which two were outlet to condenser. In area each outlets cooling nozzles water and blades root cross-sections. Cooling these areas is neces...
