摘要:
The performance of gas-fired residential sized twin pulse combustors with two aerodynamic valves for residential heating appliances is discussed. Two injection system are tested. Pre-mixed injection resulted in having better stability of anti-phase operating mode between the two combustion chambers which reduced the noise level less than 50 dB(A). The combustor shows NOxemissions of 25 ppm and a thermal efficiency of 93% over a wide turndown from 1,100 to 6,000 W. At a lower heat input region, the combustor can still operate in the anti-phase mode with fuel supply to only one combustor. It is shown that twin-valveless pulse combustors have the potential for compactness, low noise, and efficient operation over a wide turn down ratio for residential use.
