    Reduce Boiler Tube Leaks with Better Steam Temperature Control

    As the contribution of renewable energy sources grow on electrical power grids, so does the cycling its intermittency creates for power producers. This cycling affects steam used to drive the generators. For power stations where the electric generators are steam-driven, this steam is created by coal, nuclear, geothermal, solar thermal, waste incineration and sometimes natural gas. Boiler tube leaks caused by frequent...

    Reducing Thermowell Dynamic Stress Forces

    Thermowells are traditionally a circular cylinder installed into the piping to protect the temperature sensors from the flow. From an Emerson whitepaper, Thermowell Calculations : As a process fluid passes around the thermowell, low pressure vortices are created on the downstream side in laminar, turbulent, and transitional flow. The combination of stresses, generated by the static in-line drag forces from fluid...

    Building IIoT—Temperature Measurement Style

    One quick example of the Industrial Internet of Things (IIoT) in action is temperature measurement. Traditionally, these measurements included piping or vessel penetrations, thermowells installed, RTD or thermocouple sensing elements and transmitters, wiring/fittings/junction boxes/conduit/cable trays/etc., marshalling panels and connections in the control system I/O. For critical temperature measurement and control this...
