Abstract

The invention discloses a system and a method for testing the thermal efficiency of a boiler, relates to the technical field of thermal power generation, and solves the problem that boiler combustionoptimization cannot be accurately adjusted in real time due to the fact that the currently obtained boiler thermal efficiency cannot meet the real-time performance and accuracy at the same time. The system comprises a first pulse laser coal quality online detector; the first pulse laser coal quality online detector is arranged above a belt of a coal feeder and is used for detecting components andheat value of coal as fired on the belt of the coal feeder. The system and the method for testing the thermal efficiency of a boiler are used for saving energy and reducing consumption.

Description

technical field [0001] The invention relates to the technical field of thermal power generation, in particular to a system and method for testing boiler thermal efficiency. Background technique [0002] Energy saving and consumption reduction in thermal power plants is an extremely important task. High energy consumption will not only affect the economic benefits of the enterprise, but also cause damage to the environment. Therefore, it is necessary to calculate the thermal efficiency of the boiler to provide guidance for the optimization and adjustment of boiler operation to reduce energy consumption. [0003] Boiler thermal efficiency is mainly affected by various heat losses. Currently, there are two methods for measuring various losses: off-line test and simplified online test. Although the offline test has high test accuracy, the test process usually needs to go through the process of sampling, sample preparation and testing. The whole analysis process takes a long tim...
