Abstract

PURPOSE: To positively prevent the overshooting and undershooting of the temperature of a feed hot water by computing the necessary calory with respect to the set temperature based on the feed water temperature and feed water flow quantity to control the gas combustion quantity in accordance with the computed value.
CONSTITUTION: A flow quantity enser 7 and a temperature senser 8 which detect the feed water flow quantity q and feed water temperature Ti respectively, are provided on the inlet side of a heat exchanger 1. The output signals of respective sensers 7 and 8 are supplied to the computing part 9. The computing part 9 computes a necessary calory Q with respect to the set temperaturs Tsp based on respective output signals supplied, in accordance with the equation, Q=(a/η)(Tsp-Ti), where a represents a specific heat; Ti, an output signal of the temperature senser, (and η, a heat exchange efficiency). A signal with respect to the necessary calory Q thus obtained is inputted to the driving part 4 to control the combustion quantity of a gas G with respect to the gas burner 5. Accordingly, the overshooting and underhooting of the feed water temperature can be prevented and constantly excellent temperature control can be performed.
