Abstract

The invention discloses a method for boiler real-time on-line monitoring-based measurement of an optimum work efficiency of a generator set. The method comprises the following steps: step one, measuring a percentage of an oxygen component in smoke during product exporting; measuring one of a supply quantity of coal of a coal pulverizing system during product exporting, a total air volume during product exporting, and a gas volume during product exporting and measuring a primary air volume of the coal pulverizing system and inlet and outlet temperatures of a coal mill; step two, according to the measurement results, solving one of a boiler combustion heat release amount, a coal heating value, and a coal quality component by an empirical equation so as to obtain real-time monitoring measurement data of the coal electric burning boiler performance; and step three, on the basis of different coal qualities and environment parameters during set running, determining whether the power supplying coal consumption of the set on the combination condition is the minimum one for different loads. The provided method has the following beneficial effect: deviation of the heating value and the coal quality component due to the time-lag effect caused by the water-steam system heat accumulation can be avoided.

Description

technical field [0001] The invention relates to a method for monitoring and measuring the optimal working efficiency of a generating set, more specifically, it relates to a method for measuring the optimal working efficiency of a generating set based on boiler real-time on-line monitoring. Background technique [0002] In today's world, energy is increasingly scarce and environmental pollution is becoming more and more serious. While accelerating the development of renewable energy, more attention should be paid to energy conservation and consumption reduction in traditional industries. Thermal power plants are not only power generation enterprises but also energy-consuming enterprises. How to improve the operating economy of thermal power plants and reduce energy loss and pollutant emissions has become a hot topic of research at home and abroad. The thermal power plant operation optimization system is increasingly showing its importance as a function of guiding the optimal ...
