Advantages and Applications of Thermocouples in Garbage Incinerators
Date: 2025-12-05Read: 6

In the field of waste incineration treatment, accurate temperature monitoring is the core link to ensure the safe and efficient operation of incinerators.Eby-WRNLGAs a professional temperature sensor, the thermocouple of the waste incineration furnace has become a key equipment for temperature control in the waste incineration industry due to its unique material technology and design concept. The following analyzes its technical advantages and practical value from three aspects: material characteristics, structural optimization, and application scenarios.

1、 Material technology: a dual breakthrough in high temperature resistance and corrosion resistance

The environment inside the garbage incinerator is extremely complex, and the flue gas temperature can reach up to1200℃Above, it also contains highly corrosive substances such as chlorides and sulfides.Eby-WRNLGThe thermocouple adopts a double-layer sleeve structure, with an outer layer ofCYT301High temperature corrosion-resistant alloy, which is formed by adding elements such as cobalt and niobium to nickel based alloys through solid solution strengthening process to form a stableNi3The oblique lattice phase not only enhances the mechanical strength of the casing, but also effectively resists pitting and crevice corrosion in chloride media. The inner layer is made of corundum (alumina) material, which has a melting point exceeding2000℃It can isolate the direct impact of high temperature on temperature sensing components, while avoiding the corrosion of metals by acidic condensate.

Experimental data shows that the thermocouple is1200℃Continuous operation under high temperature12After a month, only the surface of the casing appeared0.2mmUniform oxide layer without cracks or perforations, far exceeding ordinary thermocouples6-8A lifespan of one month. In addition, its nano alloy coating technology penetrates metal ceramics to achieve the hardness of the casingHRC65Above, the wear resistance has been improved3Multiple times, it can resist the erosion and wear of particulate matter in smoke.

2、 Structural optimization: balance between precise temperature measurement and rapid response

Regarding the transient fluctuation characteristics of the temperature field inside the garbage incinerator,Eby-WRNLGThe thermocouple adopts an armored core design, which encapsulates the temperature sensing element in a diameter of only6mmThe metal sheath significantly shortens the heat conduction path. Its thermal response time(T0.5)InΦ16Under the diameter of the pipe≤90Seconds, improved compared to traditional thermocouples40%It can capture the drastic temperature fluctuations inside the furnace in real time. Meanwhile, the cold end section adopts316LAnti corrosion stainless steel is seamlessly connected to the sheath through vacuum brazing technology, effectively blocking the corrosion of condensed acid on the connection part and ensuring the stability of signal transmission.

3、 Application scenario: Standardized solution for temperature control in multiple industries

In addition to the field of garbage incineration, this thermocouple has been widely used in industries such as hazardous waste disposal, steel smelting, and cement production. For example, in a hot blast stove project at a steel plant, it was achieved through-40℃~1350℃The wide temperature range measurement capability enables precise control of combustion chamber temperature, resulting in improved fuel utilization efficiency; In a chemical waste gas incinerator, its resistanceHClCorrosion characteristics prolong the maintenance cycle of equipment and save replacement costs.

Eby-WRNLGThe thermocouple of the waste incinerator has achieved a triple breakthrough in high temperature resistance, corrosion resistance, and fast response through material innovation and structural optimization. It not only provides reliable temperature measurement tools for the waste incineration industry, but also promotes the upgrading of high-temperature monitoring technology in multiple fields through standardized design. With the increasingly strict standards for solid waste treatment, such high-performance thermocouples will become the core equipment to ensure the safe operation of industrial furnaces.
