Title:
HOT-WATER SUPPLY BURNING EQUIPMENT
Document Type and Number:
Japanese Patent JP3859811
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To supply hot water by setting delayed water temperature rise hot water in a hot-water supply heat exchanger to a hot water set value.
SOLUTION: A feed water passage 2 is connected to an input side of a hot-water supply heat exchanger 1, and a feed water passage 3 is connected to an output side. The passage 2 communicates with the passage 3 via a feed water control bypass passage 18. A second flow control means GM2 is provided at the passage 18, and flow of hot-water side joined with water output from the passage 18 is controlled by a first flow control means GM1. When hot water supply operation is started in the state that hot water of delayed temperature rise is generated in the exchanger 1, the means GM1 and GM2 are controlled in a direction for eliminating the delayed rise to control a flow ratio of flow Q of hot-water side to bypass control flow QBP passing the passage 18 to eliminate the delayed rise. At the time of mixing operating state of eliminating the delayed rise, only feedforward heat amount for raising the flow Q of hot water side from a feed water temperature to hot water supply set temperature is supplied at the time of mixing operation state of eliminating the delayed rise to heat the exchanger 1.
