### re calculation of flame momentum of a multi channel burner

Dear chari

Thanks you

To give calculation flame momentum on the basic of % PA* Velocity.

But sir i want know any conversion  factor between above flame momentum to N /MW

Most of expert given flame momentum in N /MW  flame optimisation.

### re calculation of flame momentum of a multi channel burner

Dear Sharma ji

The burner momentum in N/MW is calculated as

A (N/MW) = (M x V)/P

where M = Mass of air in kg/sec

V = velocity at nozzel in m/s

and P = Heat Capacity at sintering zone in Megga watt.

For old burners the value is 7 to 12 N/MW

for new burners it is 4 to 10 N/MW
