Abstract

PURPOSE: To enable extremely preferable temperature control even when the feed water flow quantity is either abruptly changed or is in stable state by computing a necessary energy with respect to the set temperature based on the feed water flow quantity, and controlling the quantity of gas to be burnt in accordance with computed value.
CONSTITUTION: A flow quantity sensor 7 for detecting the feed water flow quantity on the inlet side of a heat exchanger 1, and the output signal q of the above sensor 7 is supplied to a computing part 8. The computing part 8 computes the necessary calory Q with respect to a set temperature Tsp on the basis of the output signal q in accordance with the equation, Q=(a/η).(Tsp-Ti)q, where a represents a specific heat; η, a heat exchange efficiency, and Ti, a feed water temperature. A signal corresponding to the necessary calory Q thus obtained is inputted to a driving part 4 to control the combustion quantity of a gas G with respect to the burner 5. In a certain control state, when the flow quantity q changes largely a necessary calory Q1 in a new flow quantity Q1 is computed, and a signal corresponding to this necessary calory Q1 is inputted to the driving part 4.
