Along with power augmentation, ECT also provides products for online and offline gas turbine compressor
cleaning, such as this skid featuring a combination of online cleaning and
power augmentation capabilities.

patterns be checked twice yearly if possible and once yearly if under base load
conditions. The full nozzle assemblies
should be inspected during scheduled
outages for cracks, loose connections,
etc., as part of the standard gas turbine
maintenance practices.”
Tassone also indicated that ECT has
received no complaints from its customers showing any adverse effects on
turbine component life by using a combination of evaporative cooling and
mass flow augmentation. “In normal
applications, the inlet assembly and
compressor should be inspected during routine maintenance to ensure the
components have not incurred any erosion or corrosion effects.”
With regard to lowering gas turbine
exhaust emissions, NOx emissions tend
to lower during the injection of water
either by fogging or power augmentation. “As the compressor temperatures
are lowered, there is a reduction in the
NOx levels. However, these fluid injection technologies are not specifically
designed to achieve lower emission,
but rather to improve gas turbine performance,” Tassone said.
All of ECT’s technologies are designed to ensure safe and dependable
results. The online, crank wash and
mass flow augmentation equipment are
all engineered for ease of installation
and maintenance, minimize vibration
and extend life. The various liquid
injection technologies offered by ECT
can be combined onto a single skid as a
turnkey package. This lowers the up-front purchase and installation costs.
Customers can also select discrete functionalities using ECT’s modular technology for future expansion.
Customers also have the option to
purchase component subassemblies.
This allows the end user the advantage
of assembling their own new package
or upgrading existing equipment.
“These technologies can be combined
with existing hardware. This allows the
plant to effectively upgrade their existing equipment without a complete
rebuild. In one case study, by replacing
the fog nozzle tips, ECT was able to
lower the operating pressure of the fog
skid, lower the pump failure rate and
still achieve maximum fog inlet cooling,” said Tassone.
ECT designs and manufactures specialty chemicals and cleaners to improve
the performance of turbomachinery and
internal combustion engines. “We offer
custom nozzle assemblies along with
specialty pump skids to accommodate a
wide variety of flow rates, pressures, liquid media and site-specific requirements. ECT’s — and their affiliate’s —
equipment is placed in gas turbine,
diesel and centrifugal flow compressor
applications worldwide.” A
