“…During the computational process, the overfiring ration (a) and the domestic hot water load ( H~) are varied to monitor equipment performance under various operating conditions. The AFUE program calculates Mannual by use of equations ( 4 ) , ( S ) , (6) and (7) for each value of a (corresponding to a specific design fuel flow rate), and for each value of domestic hot water load (H,).…”
