This paper provides a feasible way to suppress flame flickering under normal gravity and atmospheric pressure without changing the fuel mass burning rate, thus promoting steady-state combustion. By periodically reciprocating one burner horizontally in a dual burner system, a death mode (namely, amplitude death of flame height oscillation) is generated around the critical burner separation distance, which is a transition point between in-phase and antiphase flickering modes of the two flames. The criterion to obtain a complete death mode region in a general dual burner system (with horizontal movement function) is defined by two dimensionless parameters, which respectively quantify the burner configuration and its dynamic performance.
