An exhaust temperature spread refers to a high differential in readings between the thermocouples placed radially around the exhaust of a gas turbine. This can be indicative of combustion troubles.
So, what causes most exhaust temperature spreads? Most are due to mechanical issues such as plugged or enlarged fuel nozzle orifices, and fuel nozzle assembly problems.
MD&A has In-Situ Air Flow Test stand capabilities that allow for immediate and conclusive data on gas turbine nozzle performance. We are your full-service, OEM-alternative!

MD&A welded and repaired the HPIP outer shell, HP & IP inner shells, and nozzle box on a 677MW large steam unit, after inspections showed axial distortion & mechanical damage of the critical positional fits.
The damage was caused by galling during an overhaul disassembly, and out-of-roundness of the HP and IP inner shells due to operational thermal stresses.
Because of our vast knowledge and experience with different types of OEMs, MD&A experts are capable of performing any welding repairs. We are your full-service, OEM-alternative! https://mdaturbines.org/CasingWeldRepairs #powerthroughexperience #GTAWwelding

Over time the seals on your steam turbine may deteriorate and components can become distorted, causing efficiency and operational issues.
MD&A has developed specialty products, like the Guardian® packing rings and Vortex Shedder® tip seals to address these issues.
In one case after the installation of our products, efficiency was measured at an impressive 3.5%, giving the customer 1.4% incrementally improved efficiency. https://mdaturbines.org/SealingSystems

Heavy Load! MD&A recently performed a Stator Replacement, removing the old stator off the foundation and replacing it with a brand new #Stator. The generator stator traveled by large vessel overseas, then by railcar to the site.
In addition, the project included a full test and inspect on field, where MD&A experts rewound, applied a blocking modification, and restored the journals. Following receipt of the upgrades, the field was high-speed balanced with a thermal heat run at MD&A’s high-speed balance facility in St. Louis, MO.

MEET THE EXPERT: 40th Anniversary Edition. We asked some of our most tenured employees to share their thoughts on working for MD&A.
Tom Brittain, General Manager of the Generator Division shares his thoughts on how MD&A has changed over the years, his favorite memories, and more.
See what Tom had to say: https://mdaturbines.org/TomBrittainExpert
Our experts inspected, straightened, and high-speed balanced an A-10 frame rotor on a 3600 rpm, 90 MW combined-cycle unit.
The rotor was received with a bow of 0.040” TIR in the N-3 packing area. Because of this, the rotor would not be able to spin up through critical speeds, let alone get to rated speed without severe vibration.
MD&A straightened the HP rotor to 0.003” TIR using an initial stress relief operation, as well as multiple iterations of thermal straightening. It was then balanced and tested without incident.

CASE STUDY: MD&A experts performed two generator stators and field rewinds and a modified hot gas path inspection for a forced outage.
Both generators were experiencing aging and flooding due to leaking hydrogen coolers. We determined the proper solution was to rewind both stators and to rewind one field with new copper.
At the same time, our Gas Turbine Services specialists performed a modified hot gas path inspection on the turbine, along with refurbished gas turbine parts.
This project is just one example of our in-depth analysis, emphasis on precision, attention to detail, and commitment to owner/operator online trust. https://bit.ly/3rYeKCq #PowerThroughExperience #PowerPlantGenerator #GasTurbine
