Here are a few others to consider: Bethlehem Steel - a shell of its former self and dying. A victim of obsolete technologies and overseas competition. Westinghouse - Sold off in parts. The great power generation division is now part of Siemens. Became an afterthought in the CBS empire and...

amrh, I'm not sure what, in particular, you are looking for. In general, ambient temperature (aka compressor inlet temperature, or CIT) has a definite impact on gas turbine performance based on the fundamental principals of thermodynamics and the ideal gas law (pv=RT). The gas turbine is...

KANN, In general, the location of the drips/drains on high energy piping systems will be determined by the physical layout of the piping system. Superheated steam will not generally require condensate drainage during steady-state operation, however, the transient states (such as start-up...

KANN, A lot of good advice in the previous responses. One additional issue to consider, which you raised in your original question, is the location/configuration of drips or drains. This will be a key issue for any piping that has the potential for water induction into the steam turbine...

joan271273: The spreadsheet that is used quite a bit is Excel but this does not tell you how to develop a proforma. The initial model is generally developed by your financial folks to ensure it captures all of the necessary costs/impacts. It really depends on what the proforma is intended...

Try the ASME. They publish a Journal for Engineering of Gas Turbines and Power on a monthly basis that will probably have a back-article or two on this subject.

Building is a 15-story office building. Total estimated peak electrical load is 7500 kW. Cogen is sized to match building thermal load and will provide a peak output of 3,800 kW with remainder of load served from utility connection. Expect to split the building sevice such that the cogen...

Thanks, Rich2001. I'll take a look.

Hi all, I'm looking a an option of installing a natural gas fired engine generator on the roof of a building. The natural gas would have to be piped from the Gas Company's meter/regulating station (at grade) up to the roof (15 floors up). I am concerned about running a gas pipeline in an...

Try "Maintenance Manager's Standard Manual" by Thomas Westerkamp. Chapter 28 deals with recommended maintenance programs for air conditioning equipment.

Very good insight. We have considered operating in parallel with the local utility as an option. However, we are interested if we can operate our in-house generation (it is a cogen) to feed particular loads while the utility feed supplies other loads and the in-house generation is not...

I have been reviewing a proposal from a company to install on-site power generation (natural gas fired engine generators) to handle a part of their building load. The remaining load would still be supplied from the local utility power grid. Has anyone dealt with this situation? I am...

There is one combined cycle power plant in the United States that has a CO2 recovery plant that removes CO2 from the exhaust gases (Northeast Energy Associates in Bellingham, MA). It has been operating for 10 years and recovers the CO2 via chemical absorption. The CO2 is then compressed...

You might also take a look at a fluidized bed type boiler instead of a stoker type boiler. A combination of some prep to the fuel and a different boiler may make it feasible. Note that, in this day and age, you will need to address the emissions issues an provide post-combustion controls to...

Go back to the good ol' First Law of Thermodynamics which addresses the conservation of energy about a control volume (think boiler).
