Turndown ratio of a gas burner is equal to the __________________ ?
Correct answer: B. Both A. & B.
- A. Maximum to minimum heat input ratio
- B. Both A. & B.
- C. Maximum to minimum permissible gas flow rate
- D. Minimum to maximum heat input ratio
Explanation
Turndown is the range over which a burner operates satisfactorily, expressed as maximum divided by minimum firing rate. For a fixed fuel, firing rate is proportional to gas flow, so both ratios describe the same quantity.
