Patent number: 5231939Abstract: This invention relates to an in-ash unburned component estimating device for a coal-fired furnace which monitors the density of in-ash unburned component contained in burning waste gases to operate the furnace efficiently. The object of the invention is to infer and estimate from the current situation by a simple means the density of in-ash unburned component in the burning exhaust gases that affects the combustion efficiency. A furnace temperature, a load band in the furnace, a furnace contamination coefficient, a ratio of two-stage combustion air supplied to the furnace, and a coal mixture ratio are taken in as fuzzy quantities to infer fuel ratio data and correction data used to correct predetermined reference values of reference in-furnace temperature distribution, reference in-furnace air ratio distribution and reference powdered coal grain diameter distribution.Type: GrantFiled: January 30, 1992Date of Patent: August 3, 1993Assignee: Kawasaki Jukogyo Kabushiki KaishaInventors: Shinji Tanaka, Tatsuya Miyatake, Kazuyoshi Yamamoto, Yuichi Miyamoto, Eiichi Harada

Patent number: 5158024Abstract: This invention relates to a combustion control apparatus for a powdered coal-fired furnace that monitors noxious substances contained within the burning waste gases, unburned substances within the ash and the power data of a pulverizing mill in order to operate the combustion furnace safely and efficiently. The combustion control apparatus infers from the current states or data optimal control amounts that will maintain within the minimum allowable ranges the noxious nitrogen oxides and the in-ash unburned substances that affect the combustion efficiency-and thereby controls the combustion furnace with good stability. The combustion control apparatus qualitatively evaluates as fuzzy quantities the density data of the nitrogen oxides contained within the exhaust gases of the unburned substances contained within the ash, and the power data of the pulverizing mill.Type: GrantFiled: January 2, 1992Date of Patent: October 27, 1992Assignee: Kawasaki Jukogyo Kabushiki KaishaInventors: Shinji Tanaka, Tatsuya Miyatake, Kazuyoshi Yamamoto, Yuichi Miyamoto
