PROBLEM TO BE SOLVED: To provide a combustion equipment provided with a neutralizing equipment, which can accurately control the mixing of lye which is required for neutralizing drain according to the generation of the drain by a combustion equipment provided with a latent heat recovering heat exchanger, which fluctuates by a large extend according to the use related to business of the combustion equipment for preventing the deterioration of buildings and environmental pollution by acid drain. SOLUTION: In neutralizing the drain by lye prepared with a certain concentration, the mixing quantity of lye is accurately controlled in real time by arranging a neutralizing controller 24 in a combustion equipment controller 20, feed-forward processing the required quantity of combustion using the self-recognizing instantaneous parameters of external environment and the combustion, and correction processing the time delay element from the condensation to flow into neutralizing equipment of the drain regarding to the mixing quantity of the lye, the temperature of exhaust gas which changes according to the combustion air ratio, and drain condensation ratio which changes according to the difference between the inlet water temperature and flame temperature, based on the feed-forward quantity. |
