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 boiler's gas duct. A flow in the exhaust stack has been simulated by CFD. For turbulence modeling the standard k–ε model was used. Analysis of the results allowed us to optimize the waste heat boiler.

Fossil Fuel Fired Boiler Air and Gas Path

A typical coal-fired power plant with an electrical output of 500 MW requires about 50 kg s–1 of coal and about 550 kg s–1 of air to produce about 600 kg s–1 of exhaust gas. This, translated into volumetric air and gas volume flow rates at the inlet and outlet, gives about 500 m3 s–1 and 675 m3 s–1 respectively.

PROCEDURE FOR DETERMINING THE THEORETICAL

gases which are emitted by the boiler is a function of the firing rate and associated theoretical air requirements and excess air used in the combustion process. The more excess air used, the larger the volume of exhaust gases for a given firing rate and the lower the exit gas temperature. The volume rate of flow of the exhaust gas can

Diesel Exhaust Gas

Maximum exhaust flow rate as function of engine rated power The data in the chart correlates well with the traditional rule of thumb, which states that the flow rate of hot exhaust gas in m 3 /h equals the engine power in hp multiplied by 10 (or by 6 to obtain the flow rate in CFM). The reader is cautioned however that this simple rule of thumb is subject to errors as high as ±40%.
