Abstract

The invention provides a detecting platform for measuring the efficiency of an induced draft fan of a power station boiler, and belongs to the technical field of energy saving of coal-fired boilers. The detecting platform comprises a sampling device and a control device, wherein the control device is electrically connected with sensors in the sampling device through a data acquisition unit separately, and is used for collecting data collected by the sensors, the input original data of the power station boiler of the control device are combined, and the efficiency of the induced draft fan of the power station boiler is calculated. The invention further provides a method for measuring the efficiency of the induced draft fan of the power station boiler. The method for measuring the efficiencyof the induced draft fan of the power station boiler aims to solve the technical problem that an existing induced draft fan efficiency detecting method has low test accuracy, more high-altitude operations, high labor intensity and long consumed test time.

Description

technical field [0001] The invention belongs to the technical field of energy saving of coal-fired boilers, and more specifically relates to a detection platform and method for measuring the efficiency of induced draft fans of power plant boilers. Background technique [0002] The induced draft fan is one of the most important auxiliary machines in power plant boilers. The efficiency measurement test of induced draft fan is an important test item for power plant boilers. The operating characteristics of the induced draft fan can be understood through the efficiency test of the induced draft fan. According to the operating curve of the induced draft fan, the working condition area of ​​the induced draft fan can be known, and its safe operation status and energy-saving potential can be understood to provide reference for the operation and transformation of the induced draft fan. Therefore, the test for measuring the efficiency of induced draft fans is of great help to the saf...
