TTEC's MVD Thermowells are designed for applications where thermowells will be exposed to highly abrasive conditions such as are found in Power Plant Coal Pulverizers. Product life has always been a problem in these applications, where barstock wells can be eroded away within short periods of time. For these difficult applications, TTEC designed Thermowells which utilize a process known as Mechanical Vapor Diffusion (MVD).

Tungsten Carbide is fused with the thermowell material and becomes an integral part of the mass of the well. A new and substantially harder thermowell is the result of the MVD Process.

The MVD Process is normally applied to the insertion portion of the Thermowell. When applied, the significant increase in wear life is achieved without sacrificing the corrosion or temperature features of the thermowell material.

To order: Specify the thermowell part number from the TTEC Series 10000 Thermowells catalog and add Option Code "X30". Custom designs are also available.

TTEC Bearing Temperature Thermocouples and RTD's feature reliable spring loaded temperature measurements of Bearing Surfaces in Power Plants. TTEC's unique Oil Seal, Spring Loaded Fitting ensures firm sensor tip contact with the Bearing Surface. These Assemblies can be specified to the exact length needed or ordered as a KWIK-FIT Field Cuttable Probe and cut to length in the field.

For Thermocouples: See TECPAK Styles 1022,1019 and KWIK-FIT Style 1060-J, K, T or E Probes with 1060-33 Fitting and Accessories.

For RTD's: See SERIES 8000 Styles 8022, 8019 and KWIK-FIT Style 1060-A, B, C or D Probes with 1060-33 Fittings & Accessories.

Custom designs available.

Features:

• TTEC manufactures Thermocouple Assemblies for severe high temperature corrosive environments. These assemblies utilize an HR160 Thermowell or Protection Tube.
• HR160 is a solid, solution strengthened NI-Co-Cr-Si Alloy with outstanding resistance to various forms of high temperature corrosion attack.
• Outstanding High Temperature Corrosion Resistance. High levels of Cr & Si combine to form a very protective surface Oxide scale that resists attack from Sulfur, Chlorine, Fluorine, Vanadium, Phosphorous & Salt deposits to 2200 ºF (1204 ºC).
• Life extensions greater than 10x compared to Ni-Cr alloys & stainless steels are common.

Applications:

• Municipal, Industrial, Hazardous & Nuclear Waste Incinerators
• Utility Boilers
• Sulfur Furnaces
• Resource Recovery Units
• Fluidized Bed Combustion Systems
• High Temperature Furnaces, Kilns & Calciners
• Recuperators, Heat Exchangers & Waste Recovery Systems
• Cement Kilns
• Pulp & Paper Recovery Boilers

TTEC CFB Boiler Assemblies are specially designed to withstand the highly erosive conditions found in Circulating Fluidized Bed Boilers. These rugged assemblies are installed throughout the Combustor Section, Cyclone Inlets, Cyclone Outlets and in the Coal/Ash Feed Lines. They provide critical temperature inputs to the Fluidized Bed Supervisory System for indication, control & safety. TTEC CFB Boiler Assemblies utilize a unique Protection Tube with a special heavy-duty tip and the TTEC MVD Abrasion Resistant Treatment. This design has been proven to provide superior product life in very erosive environments with temperatures as high as 1800°F. Customers have encountered product life of 1 year or longer in the high erosion areas and over 4 years in the low erosion areas (upper area of the Combustor). TTEC CFB Boiler Assemblies are designed to withstand hostile environments characterized by exposure to CO, CO₂, SO₂, NOX & NH₃, Bituminous Coal, Limestone, and Ash.
