Water temperature rise property to start of water temperature rise retarded to rise

摘要

PURPOSE: To enable controlling the amount of combustion with close care in details by a method wherein the amount of gas for the start-up of combustion for the resupply of hot water is corrected by an increase or decrease in a corrected amount of gas to compensate for a lag difference, which compensates the difference between the amount corresponding to a lag in start-up for the resupply of hot water and the amount corresponding to a lag in fall, and to compensate for variation in ignition performance. ;CONSTITUTION: A corrected amount of gas is obtained as a value compensating for a decrease or increase in the temperature of hot water from the difference between a drop D in hot-water temperature agreeing with falling characteristics GD and a rise U in hot-water temperature agreeing with rising characteristics GP. On the other hand, processing is done to obtain an amount of gas to compensate for a lag difference between a time lag LP in rise and a time lag LD in fall and an amount of gas to compensate for a lag in ignition (minimum throttling of gas in the case of an advance in ignition), which compensates for a lag or excess in rise of the temperature arising from variation in time of the ignition such as a lag in ignition or an advance in ignition. A finally corrected amount of gas is set by increasing or decreasing a corrected amount of gas by the amount of gas to compensate for a lag difference and by the amount of gas to compensate for variation in ignition performance. This method enables controlling the amount of combustion with close care in details.;COPYRIGHT: (C)1995,JPO
