The numerical research of the gas flow in the exhaust duct
A gas flow in the exhaust path of the gas turbine unit GPA-C-16 with a waste heat boiler is investigated. The aim of this study was to optimize geometric characteristics of the waste heat boilers gas duct. A flow in the exhaust stack has been simulated by CFD. For turbulence modeling the standard kε model was used. Analysis of the results allowed us to optimize the waste heat boiler.

Steam Calculators: Boiler Calculator
Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure. Does not include any evaluation of any complex boiler configurations or fluctuations in operation.
