    Power Generation Improved Steam Temperature Control

    Emerson’s Jeff Williams presented, Holistic Approach to Steam Temperature Control, at the 2018 Ovation Users’ Group Conference. Jeff opened describing the trend of plants being started and operated more frequently than in the past due to intermittent sources of renewable energy sources on the grid. A key challenge to this mode of operation is to maintain consistent superheat temperature in this transient environment...

    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...
