VALIDATATION OF CFD MODELS:SIMULATION OF BURNER AT RESEARCH CENTER

GOAL OF THE SIMULATIONS:

� Validation of physical cfd models: Comparison of temperature profiles, shape and flame length with experimental results

� "CFD" is a tool for comparative prediction of possible solutions

CHARACTERISTICS OF THE SIMULATIONS:

� unsteady

� hybrid mesh (1M cells)

� turbulence: kepsilon "realizable" model

� combustion: Eddy dissipation/finite rate model

� species: O2, CO2, H2O, CH4, CO, N2

� radiation: P1

GAS-FIRED INDUCT BURNERSBurner Overview

Fives

Gas fired induct burners

(Patents : FR 87/14686, CAN 580.005,Europe 88.402659.2).

Applications: HRSG supplementary firing.

Advantages: Performances in compliance with the latest European Standards for emission

TEG mode: Reburning of a part of NOx from GT: (downstream rate < upstream rate).

Fresh air mode, natural gas firing:

(mg/Nm3 eq. NO2, 3 % O2, dry basis)NOx < 200 without FGR

NOx < 100 with FGR

DIFFERENT BURNER DESIGNSDEVELOPED IN OUR TEST CENTER

12

Along the 25 past years we developed and tested num erous designs to cope with:• More and more stringent TEG characteristics

– Lower O2 content

– Higher water vapour

• Burner installation between modules– Lower temperature

– Lower TEG velocity

– Shorter space available to develop the flames

• Requirements concerning the temperature profile

• NOx, CO emissions

• Operation with fresh air

Fives
