    Improving Waste to Energy Plant Performance by replacing frequently failing thermowells.

    Improving Waste to Energy Plant Performance by replacing frequently failing thermocouples

    Background

    OEM specified thermowells were failing every 1 to 2 months. Due to the location, the removal/replacement process was challenging, time consuming and expensive.

    Measuring task

    Thermocouples were installed to monitor the very high temperatures in the ceiling and the second pass of the combustion chamber in order to monitor performance and the protection of the refractory as well as Sulphur and NOx which is a critical measurement for the emissions reporting.

    Customer issues

    The customer was experiencing high levels of thermowell failure due to corrosion caused by chlorides in the flue gas derived from burning of plastic (PVC). Inconel 800 had been selected for OEM design which was considered suitable to combat high temperatures (1000 Deg C) in the combustion zone. Chlorides were corroding the Inconel 800 thermowell within 1-2 months, resulting in failure and loss of signal.

    Due to the location, the removal/replacement process was challenging, time consuming and expensive. These measurements are critical to plant operation, frequent failures and swap outs are undesirable.

    Solution

    Special alloy material was used to manufacture the thermowells. This enabled them to withstand the high temperatures and also the corrosive effect of the variable flue gas chemical compositions.

    The result was increased reliability of temperature measurement. Inspection during the 6 monthly scheduled outage following the upgrade enabled an informed decision to confidently leave them installed until the next scheduled outage. The upgraded thermowells contributed to the safe operation of the combustion chamber refractory lining and control NOx released from the station, which is critical to fulfil emissions legislation.

  • Cyber essentials certificate of assurance

    We’re delighted to announce that we’ve received the UK Government, Cyber Essentials Certificate of Assurance.

    This certifies that CHASE International Ltd was assessed as meeting the Cyber Essentials implementation profile and thus that, at the time of testing, the organisations ICT defences were assessed as satisfactory against commodity based cyber attacks.

    The assessment was not a box ticking exercise, but a rigorous process of in-depth questions that were reviewed by cyber security professionals.

    The certification provides assurance to all CHASE International stakeholders.

    What is Cyber Essentials?

    Cyber Essentials is an effective, Government backed scheme that will help you to protect your organisation, whatever its size, against a whole range of the most common cyber attacks.

    Cyber attacks come in many shapes and sizes, but the vast majority are very basic in nature, carried out by relatively unskilled individuals. They’re the digital equivalent of a thief trying your front door to see if it’s unlocked. Our advice is designed to prevent these attacks.

  • Thermowells for corrosive environments

    Installing thermowells for corrosive environments can help you to eliminate failures between planned outages.

    Recently, one of our orders for bespoke thermowells was complete and Brian, Vanessa and Neale had an opportunity to further increase our understanding of how these items are vital within the Waste to Energy market.

    As well as being passionate about customer service we also like to improve our industry knowledge whenever possible.

    These 2m long thermowells were made for a W2E plant to solve a problem with the existing thermowells regularly failing between planned outages. The environment that these units operate in is particularly corrosive. The material that the OEM units were made from wasn’t up to the task.

    The customer provided us with a specification of the operating conditions; temperature and waste materials, in their boiler and a thermowell was designed to meet their demanding requirements. The material selected was a stocked exotic alloy. The cost of the alloy is more than other materials but not high when compared to the cost of unplanned outages due to failures.

    The adjustable, multipiece design makes it simple for the customer to swap out the old thermowells for the new ones with minimum fuss.

    Installing thermowells for corrosive environments can help you to eliminate failures between planned outages. At each planned outage, the thermowells can be inspected and assessed as to whether they need replacing at this time or whether they can be confidently left in place. The diameter of the thermowell can be measured to assess any deterioration due to corrosion or erosion. From the wear rate it’s possible to estimate the length in service and predict the optimum replacement cycle.

    Cost of ownership is only partly down to the cost of the equipment installed in the W2E plant. More significant costs are incurred from unplanned outages reducing plant availability and capability to incinerate waste and generate power.

    Motors and generators manufactured by these heritage companies are still supported. In fact the design and engineering records for many of these machines are still available. This legacy enables CHASE to offer repeat “plug and play” replacements of historical products.

    The Impak, Flowpak, Unipak and I range motors, developed in the 1970’s, 80’s and 90’s in both Bradford and Rugby are such heritage products. These robust, multi-functional, high power factor-low power cost ranges of cage induction machines, although developed and targeted for the Oil & Gas/Petrochemical Industries were also very successfully supplied into the more general industrial applications within the Power Sector, Metals & Mining and Water Industries to name but a few.

    Capital spares can be easily supplied and we are able to source equivalent spare parts wherever necessary, to extend the lifecycle of these machines.

    We are committed to supporting our customer’s in the effortless replacement of replica motor solutions which will straightforwardly exchange with existing drives, saving you both time and expenditure.

    What are thermowells made of

    For many applications stainless steel is the most cost effective and suitable material, however for corrosive or erosive environments more resistant materials are more cost effective.

    The issue with thermowells made from inadequately specified materials in a harsh environment is that they quickly fail to protect the temperature sensor inside, leading to wrong or no temperature measurement. Replacing the sensor and the thermowell requires the plant, such as a boiler, to be shut down, leading to loss of production/uptime.

    Our manufacturing partners for high performance thermowells, BKW Instruments, were in the process of turning these Stellite6 bars into thermowell tips when we visited their plant in Manchester. Stellite6 is particularly resistant to erosion and is therefore the material most suitable for harsh environments like the pulverised coal dust supply for power station boilers.

    Only Western European material suppliers are used to ensure guaranteed origin and can provide 3.1 Material Certification giving chemical analysis. They also have the capability to do Positive Material Identification (PMI) testing to ensure genuine supplies and to reverse engineer materials when diagnosing failed components.

    how long is a thermowell

    This roof mounted thermowell is 3m long! It was manufactured by our partners BKW Instruments, based only a few miles from CHASE HQ in Manchester, England.

    Some applications require the thermowell to pass through a thick wall, like the refractory lining in a high temperature boiler. The first metre might be the thickness of the boiler lining and the remaining two meters are to take the tip of the thermowell, containing the temperature sensor, to the bottom of the boiler.

    This extra-long thermowell is part of a set to measure the temperature at the top, middle and bottom of the boiler. This allows the plant engineer to monitor the performance of the boiler accurately at all levels.

    BKW manufacture thermowells in a range of materials, specific to the temperature and the environment of the application. Stainless steel is appropriate for many applications however corrosive or erosive environments require materials such as Alloy600, Alloy800, Monel, Hastelloy, Titanium or other specialist alloys and coatings.
