Preheater and precalciner kilns are shorter than a long cement kiln and contain tall preheater towers that use the heat produced by the kiln to preheat the raw materials as they move through the various stages of the tower. Thermo Sensors Make thermocouples are mounted & running successfully at many preheater furnaces.
Blast Furnace is the heart of Integrated Steel Plant. Thermocouples used in Blast furnace faces the most challenging temperature & flue gas conditions. The temperature extremity along with flue gas corrodes the outer sheath of Thermocouple resulting the failure of T/c in not more then a month. With years of experience & expertise in thermocouple Engineering, Thermo Sensors has developed a special design, specifically for Blast Furnace to give long life, thereby reducing the cost.
Semi Rigid thermocouples manufactured from mineral insulated stainless steel sheathed thermocouple cable. These thermocouples are used in a variety of processes as their many characteristics make them a good choice for general and special purpose use, their ruggedness and moderately high temperature range make them a popular choice for a multitude of temperature sensing environments. A robust temperature sensor which is resistant to bend creasing and wall splitting due to the thickness of the sheath and extreme compaction of the magnesium powder. These units are fitted with a quick release plug connector fitted directly to the sheath.
We manufacturer thermocouple for molten aluminum in Silicon Nitride outer tube featuring long life and maintenance free advantages. There is no eluted contamination into molten aluminum. Therefore, the purity of the metal is maintained. Superb thermal shock resistance. Light weight, high strength, and easy to handle. Even with flux, Silicon Nitride is hardly eroded. This ensures long life.
Thermo Sensors Thermocouple protection tube is a dense, sintered ceramic especially designed for use in many molten non-ferrous metals and corrosive chemicals. It is very strong, thermally shock resistant and dimensionally stable. Mechanical strength is retained at extremely high temperatures (over 1000C Deg). These features together with very low wear resistance, makes it an ideal Thermocouple protection tube for applications such as molten aluminum, lead, tin and zinc. Preheating is not necessary because the tubes has very low thermal expansion coefficient.
Thermo Sensors Protection tubes are also recommended for use in oxidizing environments to 1200 Deg. C. Most acids, such as hydrochloric, nitric, sulphuric, and phosphoric, do not attack it. This is also resistant to hydrogen gas.
It is well known that Glass Melting Furnace includes a melting chamber in which solid batch materials are heated to produce molten glass. The arch of this melting chamber is known as crown. To measure and control the temperature of furnace crown is important, because with the correct temperatures one can improve the service life of crown, as the overheating of the crown may cause of early erosion of crown refractory and the other side if the temperatures are low, it can affect the melting efficiency and will increase the fuel consumption. The highest temperature in melting furnace is at crown. To select the right materials and assembly is quit important as the temperature at crown is even more than 1600°C. The design we recommend is with dual protection sheaths. In most of the furnace thermocouples are placed in block pockets, but over a period of service it may get through hole. At crown there are number of points to measure in center, Right & Left, the same kind of assemblies can be used for Regenerator Crown as well.
