Abstract

The invention provides an online coal quality identification device and an online coal quality identification method. The device comprises a full-spectrum photoelectric probe, a field control box, a data acquisition and processing unit, a master control cabinet and the like, wherein the master control cabinet is connected with the field control box through a control cable, and is connected with the full-spectrum photoelectric probe through a special connection line; the probe is arranged at the same position as a field flame detection probe; a full-spectrum photoelectric sensor is arranged in the full-spectrum photoelectric probe; and flame characteristics are converted into photoelectric signals, and then the photoelectric signals are sent to an acquisition device, amplified, filtered, sent to a spectrum analysis and modeling software unit and then adaptively processed by a neutral network to obtain coal quality. The whole set of device is simple and convenient to arrange, has no influence to the external environment, particularly to the security of the device, and continuously enriches coal quality data by fired coal quality self-learning to realize the accurate online detection of the coal quality.

Description

technical field [0001] The invention belongs to the field of energy, and relates to an online coal quality identification device and method. Background technique [0002] Judging the stable state of boiler combustion, analyzing the causes of unstable combustion, and instructing operators to perform correct operations are very important and urgent problems faced by many thermal power plants. In view of this problem, it is necessary to conduct some in-depth research on the combustion stability of the boiler, and make timely and accurate judgments on the combustion status of the boiler, so as to improve the safety and stability of the unit operation, make the boiler burn stably, and reduce the fire extinguishing and The number of times of oil injection, thereby improving the economic benefits of the entire unit operation. [0003] On-line detection of coal quality entering the furnace has become a key factor in energy-saving management and combustion optimization and adjustmen...
