Abstract

The invention discloses a movable burner nozzle temperature measuring device and method. A front end measuring tube outlet of the device is communicated with a tail positioning tube inlet, a positioning turntable is arranged between the front end measuring tube and the tail positioning tube, and an angle positioning wheel is arranged outside the positioning turntable; and the outlet of the tail positioning tube is communicated with the inlet of the measuring instrument through a measuring tube line. When the device is used for measuring, the positions of all measuring points have corresponding scale records, and the measuring points can be randomly positioned in a plane while the measuring depth is changed so that the measuring points can be accurately measured at any position in the whole nozzle flame space. Due to the arrangement of the temperature measurement element and the gas channel, different measurement purposes can be achieved only by connecting a temperature measurement instrument or a flue gas analyzer according to needs, and one instrument can carry out various measurement and is complete in function. The device is convenient to disassemble, easy to assemble, convenient to store and carry and capable of flexibly meeting the monitoring requirements of various occasions.

Description

technical field [0001] The invention belongs to the field of thermal power generation equipment, and in particular relates to a movable device and method for measuring the temperature of a burner nozzle. Background technique [0002] In recent years, after long-term operation of coal-fired boilers in some thermal power plants, due to changes in the combustion mode, severe high-temperature corrosion has occurred on the water-cooled walls of the boilers, especially for boilers with opposing combustion methods on the front and rear walls. There are multiple wall thickness reductions and transverse cracks. At the same time, there are also burnouts of burners in varying degrees, which have a great impact on the safe operation of the boiler. [0003] The traditional treatment is to observe the flame at the fire viewing hole, or use a pyrometer and other instruments for simple temperature measurement. However, the measurable range of this method is small, and the measurement posit...
