Advanced power generation will be operated at higher temperatures and pressure to achieve efficiency reduce CO2 emission. This may significantly impact the use of carbon steel that previously has been used in boiler fabrication. In thi

Wood chips are often used as solid fuel in modern biomass boilers. Experiments were conducted on 22 boilers located Serbia burning wood fuel. The influence of characteristics is analyzed relation to the flue gas losses and thermal efficiency boiler. Measured useful heat output tested was 460-2585 kW. Moisture content 19.21-38.23% with a net calorific value 10177-14139 kJ/kg ash 0.84-3.59%. Ther...

The title of the paper purports to discuss the feasibility of 100% RDF firing for power generation. It is implied that it is possible to fire 100% RDF in a single boiler. However, for the case study cited, the author suggests a much more elaborate system for a 16 MW system. The flow sheet suggests 80% heat input from RDF and 20% from coal. He also suggests that three boilers handle the RDF. Thi...

Abstract: The paper presents the research results related to control of the steam boiler parameters: drum level, furnace pressure and steam pressure. It was developed the mathematical model of the water-steam system and furnace part of the boiler. Also, the paper presents the algorithm for real time detection of model parameter variations. In this context a correction method, validate through s...

Flue Gas Condensers (FGC) are used to increase the thermal output of biomass boilers. This reduces emissions per unit produced energy but furthermore, fine dust particles will be collected in condenser. These condensers therefore have a double effect on specific particulate matter emissions. In addition mechanisms that cause particle capture such as thermophoresis and diffusiophoresis, other ag...

A numerical simulation for analysis and optimization of the performance NOx production was applied to a natural gas fuel boiler in South Pars Gas Complex. For this purpose, nine actual environmental operational parameters were measured recorded every two hours then averaged daily year. Using thermodynamic laws, important such as body exhaust flue losses, well thermal efficiency exergy efficienc...

In the Modern scenario, the naturally available resources for power generation are being depleted at an alarming rate; firstly due to wastage of power at consumer end, secondly due to inefficiency of various power system components. A Combined Cycle Gas Turbine (CCGT) integrates two cycles- Brayton cycle (Gas Turbine) and Rankine cycle (Steam Turbine) with the objective of increasing overall pl...

Creep resistant alloys designed for power plant applications like thick section boiler components, steam lines, turbine rotors and turbine castings must be reliable over long periods of time in sever environments. Besides high creep strength these materials must exhibit also other properties, i.e. good corrosion and crack resistance as well as good weldability. The environmental impact and econ...

Combined Cycle Gas Turbine (CCGT) integrates two cyclesBrayton cycle (Gas Turbine) and Rankine cycle (Steam Turbine) with the objective of increasing overall plant efficiency. In modern gas turbine the temperature of the exhaust gases is in the range of 500 oC to 550 oC. Modern steam power plants have steam temperature in the range of 500 oC to 630 oC. Hence gas turbine exhaust can be utilized ...
