Abstract

The invention discloses a hearth outlet smoke temperature on-line soft-measurement system of a coal-fired boiler and a measurement method of the hearth outlet smoke temperature on-line soft-measurement system. The measurement method comprises the following steps that (a) a smoke physical property parameter module is built; (b) a working medium lateral heat-absorption module and a low-temperature area outlet smoke enthalpy value module are built; (c) a hearth outlet smoke enthalpy value is obtained according to the step (a) and the step (b), and the hearth outlet smoke temperature is worked out. The hearth outlet smoke temperature on-line soft-measurement system of the coal-fired boiler and the measurement method of the hearth outlet smoke temperature on-line soft-measurement system can continuously monitor the average temperature of an outlet fracture surface of a hearth on line, and are easy to operate, small in investment of additional hardware and suitable for various boiler types.

Description

technical field [0001] The invention relates to the technical field of computer monitoring, in particular to an online soft measurement system for flue gas temperature at the furnace outlet of a coal-fired boiler. Background technique [0002] At present, as the capacity of coal-fired thermal power units increases, their structures become more and more complex, and more and more parameters need to be detected and controlled, which brings new issues to control and optimization. The online soft measurement system for flue gas temperature at the furnace outlet of coal-fired boilers is used to measure the temperature distribution of the furnace outlet section of large-scale power plant boilers. The exit section is the exit smokestack located in the horizontal flue of the boiler, and the positions of the exit smokestacks are different for the tangential combustion mode, the opposite combustion mode, the front wall combustion mode and the W flame combustion mode. [0003] The out...
