special thermocouple water circulating fluidization bedcirculating vulcanization bed wear-resistant thermocouple is my company after several years of field application and combined the improved styling products specifically for circulating fluidized bed boiler temperature measurement. Thermocouple protection tube of high temperature alloy, gold service life of the circulating fluidized bed wear-resistant thermocouple protection tube 8 ~ 16 up. 的特点。 1 circulating fluidized bed wear-resistant thermocouple treated with density of high temperature alloy surface hrc76 rockwell hardness ( About vivtorinox1750, ceramics class) Is8times ordinary stainless steel hardness. Hardness is lower than hrc60 common wear resistant materials. 2 sheathed金属蠕变高:1850 ~ 2050℃; Melting point: 2100 ℃ で, 1800 ℃ high temperature burning is not bending deformation. The3surface stainless steel alloy layer and matrix of the whole, the thermal expansion coefficient and thermal resistance are the same, not in high temperature cracking. 4 high temperature generated oxide film, effectively prevent so2gas, oxidation corrosion. Along with the circulating fluidized bed boiler ( Circulating fluidized bed) In the popularization of China's power industry, the ideal high temperature corrosion resistance, and fluidized bed wear-resistant thermocouple monitoring is a priority of furnace temperature. Circulating fluidized bed boiler temperature control points: 1, the main bed fluidized bed dense-phase zone bedfluidized ( Distribution board) , temperature range of 0 ~ 1100 ℃ で, containing coal, and contains a lot of burning hydrogen sulfide, sulfur dioxide, ammonia, co2corrosive gas fluidized state, material erosion power. Fluidized bed freeboard, the range of 0 ~ 1100 ℃ で, curing condition of materials have very strong scouring force and corrosive gas. 2, cyclone separator entrance and feed back to the temperature range of 0 ~ 900 ℃ で, entrance isabout25 ~ 27 million/s high speed air flow, and contain particles medium, strong erosion force. 3, fluidized bed cooling of slag temperature range of 0 ~ 800 ℃ で, and contain particles and carbon monoxide, carbon dioxide, sulfur dioxide, hydrogen sulfide and other corrosive gases. In view of the above measurement environment, the company developed a new generation of high temperature resistance, corrosion resistance, wear resistance thermocouple. The product is durable, safe and reliable, long service life, and convulsions of good performance, high coefficient of heat transfer, oxidation, thermal shock, resistance to high temperature wear resistance, corrosion resistance, and no nodules, slagging, installation convenient use, can be used for the temperature to 1300 ℃ temperature measurement occasions, is our country existing high-alumina corundum, and graphite, silicon oxide, carbide and other materials of the thermocouple protection tube of alternative products throughout the product structure design of vibration resistance. Circulating fluidized bed boiler is the preferred temperature sensor. The main technical indicators; Measuring range: 1 0 ~ 1250 ℃ for 2 wear hardness: ( Hardness) で す 603:30 m/aggressive resistance4corrosion, carbon dioxide, sulphur dioxide: company, hydrogen sulfide and other corrosive gas5spray, nh3and welding layer density: & gt; 98% 6:30 basic knot strength private mpajacket pipe specification: phi 25 mm aboveorder need to know: 1 marked temperature thermocouple, graduation date, use. 2 thermocouple protection tube diameter, length.
