The internal stainless steal liner plantes are in good shape, no repairs necessary.
I am able to drill through the outer casing wall (or cut through if need be).
Internal access in areas were the tube banks and baffels are located is impractal. Access would require moving large tube banks, and then the inner skin.
Externall access is for the most part un-restricted.
Has anyone used or experience with Kaowool Pumpable insultation?
I have three, 20 year old Heat Recovery Steam Generators with numerous hot spots. Many of the hot spots are in inexcessable areas.
Thank You
Anyone have experience using Biodiesel as the primary fuel for Combustion turbines?
What issues did you experience?
Specifically:
-combustor/fuel nozzels
-filter clogging
-cold weather performance
-above ground storage tanks
Thank You
I have three simple cycle Combustion Turbine sites that use diesel as a backup fuel. Each site can store inexcess of 100,000 barrels of diesel.
Any information or directions to standards and Industry Best Practices regarding diesel fuel maintenance, rotation, and long term storage is...
The exhaust stacks on my combustion turbines are not lined, i.e. bare steel. Every time we start a unit, it rains rust flakes. A vendor has offered to "flame spray an aluminum coating" on the inside of the exhaust stack.
Does anyone have experiense with corrosion in this area? Does anyone...
I have corrosion problems in the exhaust stack of My Pratt & Whitney simple cycle combustion turbines. A vendor claims he can solve my corrosion problems by flame spraying the lower 20 feet of the exhaust stack with Aluminum (sorry no alloy specifications yet). Exhaust stack temperatures can...
At my utility the following are trench depth standards:
600V - 50Kv Min. = 76cm, prefered = 90cm, Max. = 122cm
Allowable exception due to rocky soil conditions are as follows:
All cable in schedule-80 conduit, allowable trench depth to top of conduit = 46cm.
All cable in DB 120 conduit with...
I am comparing my utility planning practices with prevailing practices. With that in mind I have some questions I would greatly appreciate your responce on.
The definition of Utilization Factor (UF) we use/go by is: UF is the ratio of the maximum demand of a system to the rated capacity of...
I would like to ask a few questions regarding Asset Utilization Factor to compare our pratices with prevailing paratices.
Utilization Factor (UF) as we define/use it: UF is the ratio of the maximum demand of a system to the rated capacity of the system. In other words, the UF indicates the...
GregLocock Excellent point!
Hydrogen being about 6 times less dense than Methane. Power consumed in a compressor being directly proportional to density. Everything else being equal (and perhapse a little over simplified). Hydrogen (gas) transport via pipeline should be significantly...
The Heating Value range for Natural Gas is approximatly 38.1 to 42.5 MJ/kg. The heating value range for hydrogen is approximatly 120.1 to 141.9 MJ/kg. The economics of transporting natural gas via pipeline is well established. Natural gas transmission pipelines are frequently designed and...

Is there an upper limit (theoretical and/or practical) of the DC voltage for "splitting" the hydrogen-oxygen bond? What is the upper limit based on?

Interesting patent, I looked up the patent on the US patent office web site. The pilings on the piers I can look at...
My original question had to do with; what to do with off-peak electrical power produced from a tide stream generator. Given that tidal flows are very predictable (especial comparied to other forms of alternative energy) but frequently will not match up with peak electrical requirements...
Power lines are not with out losses. In fact, transporting hydrogen via pipeline is more effcient (less energy lost) than transmitting electricity via transmission lines for distances over approximatly 200 miles. The exact distance escapes me, the point is that over realtivily short distances...
I agree that the production of hydrogen and the subsequent use of hydrogen to produce electricity are inefficent. However, all thermal power cycles share the same/similare ineffciencies. If one then compares the effcientcies associated with the production, transport, and storage of the...
OK,I will admit my ignorance of photocatalytic materials, and platinum production. I was/am interested in the possibilities of using ocean tide streams to generate electricity. Since tide flows are cyclical and often do not corrispond to peak electricity demands, I was also interested in using...
