Title:
HEAT FLUX SENSOR INSTALLED ON BOILER WATERWALL TUBE OF THERMAL POWER PLANT
Document Type and Number:
WIPO Patent Application WO/2020/138763
Kind Code:
A1
Abstract:
The present invention relates to a heat flux sensor installed on a boiler waterwall tube of a thermal power plant and, more specifically, to a heat flux sensor installed on a boiler waterwall tube of a thermal power plant, wherein the heat flux sensor is installed by drilling a hole into a membrane which connects a water tube forming a boiler waterwall and an adjacent water tube, thereby making it possible to secure accuracy and durability of the heat flux sensor for measuring a heat flux inside a boiler, ensuring safety of the boiler by eliminating a cutting process and a welding process of the waterwall, and enabling a simple installation, and as the problem of damaging thermocouples caused by a heat source in the welding process such as pin welding is simply solved by means of a fitting-engagement method by drilling a hole into the membrane of the boiler, there is no damage to the thermocouples, and when the heat flux sensor is broken or replaced, the sensor can be easily disassembled and assembled to facilitate maintenance and reduce maintenance costs.
