Waste Heat Recovery Boilers (WHRB's) enhance the thermal efficiency of gas turbine power generating plants by capturing the heat from the exhaust gas and utilising it to raise steam for increased electricity production or district heating. Under normal conditions the exhaust gas from the turbine is cooled from around 550°C to 80°C.Learn More

Mar 03, 2021 · Summary. Economizers lower the consumption of fuel for a given steam demand. They also reduce thermal stress in the boiler and add heat transfer surface area to the boiler system. "By recovering waste heat, an economizer can often reduce fuel requirements by 5% to 10% and pay for itself in less than 2 years.".Learn More
thermal analysis of the diverter damper which gives us the temperature distribution and thermal stresses induced in it. Steady state thermal analysis is assumed. By using the analysis software Ansys Workbench V14.0, color results are generated. Key words: diverter damper; waste heat recovery boiler system, thermal analysis, ansys I.Learn More
