desi, cooling or humidify (!) inlet air will decrease the amount of compressor power. so if u can cool inlet air it is advisible however a refrigeration cycle will need power which will influence the total efficiency (probably lower). For swirl flash technology see: www.alphapowersystems.nl

For any heat transfer problem: VDI waermeatlas. Cees-Jan

Mr Muralidaran, I work at a dutch company which has a broad experience with boiler diagnostics. What we can do: Performance Assessments (boilers): -Burner / Soot Blower Optimisation -Extending Inspection Intervals -Performance (fouling) Monitoring -Boiler Thermal Design Optimisation Technical...

For a coal fired plant. approximately: HP 25% Load IP 45% Load LP 30% Load adding up to 100% regards, Cees-Jan

PSE, I am a mechanical engineer (MSc, Thermal Power Engineering) and if I look around me I see that the choice you refere to really depends on someone's interest and personality. Both specialists and consultants are needed and the first type is mostly more the quiet puzzle-solving type while...

Is it possible to upgrade manure gas to natural gas and actually inject it in the gas infra structure for a more sustainable society? Or does anybody know any projects as such? The manure will produce a H2S rich gas and must be treated accordingly, but will the gas from the manure not change...

Robski, calculating the water temperature is not so simple as it seems. Various factors play a role (indeed sunlight, depth of the pond, location etc etc). If u use the water in your condenser and want to know the temperature of your water you have to measure or use a correction (water...

Don't you think it's time for engineers all over the world to use the same system?? Ofcourse this must be the metric system! c-j

TBP I totally agree with you. It's the way things work. I find that by programming the relations in the VDI-warmeatlas, which is the best book on the topic, u can calculate any heat transfer problem. Oh yeah the book is in German and metric, of which the latter is the way we engineers should...

Q. Is the hydrogen used in a gasturbine? Hydrogen combustion in a gasturbine will produce (only!) thermal NOx due to the higher adiabatic flame temperature: but no need for a deNOx measuures. Cees-Jan

Check http://www.ieagreen.org.uk/capt1.htm You will find basic knowledge of CO2 capture. Furthermore you will find out that CO2 capture decreases plant efficiency by approx. 10 pct points, and will result in much higher energy prices.
