# PNG burners replacement with Induction stoves

## PNG burners replacement with Induction stoves

(OP)
Hi All,

We are planning to replace PNG fired burners with induction stoves. Some burners of type T70.

What is the criteria for one to one replacement of a PNG fired burner with an induction stove ?

Do i need to find the BTU output of T70 burner and then equate that BTU to an induction stove kW (while considering their efficiencies) ?

We have done some preliminary calculations of efficiencies of PNG fired burner and an induction stove. The farmer having 45% and latter found to be 75% to 80%

is it the correct process ?

kindly suggest.

Thanks,

### RE: PNG burners replacement with Induction stoves

(OP)
Dear Sirs,

Please vet this approach below >>

A T78 burner specs:
Length 100 mm, dia 117 mm, working pressure 4.5 psig, gas consumption 3/550 kg/hr, rated heat output 40,250 kcal, inlet 3/8 inch.
So if i equate this 40,250 kcal to kW then it comes to 46.82 kW.

A PNG burner has approx. 40% efficiency.
40% useful energy of a burner is 16,100 kcal (40% of 40,250).

To achieve this kcal with 80% efficient induction stove 20% is added.
16,100 plus 3220 kcal. Total 19,320 kcal.

In kW it is 22.5 kW. So i need 22.5 kW induction stove for replacing a T78 PNG burner.

Is this approach ok ?
