Hazardous Area Classification

Which part? Be specific.

Your question is far too broad. Same with your (very general, non-specific) gas turbine fuel consumption question.

That is what schools are for.

For such elementary questions you should use a search engine (Google, or any of the others) to get your basic, "student" questions answered.

Practical Guidelines for Electrical Area Classification in Combustion

If you have specific problems, such as "I have a (brand xxxxxxx, model # xxxxxx, located in (countryxxxxx) that has a problem with the xxxxxxxx.

Questions such as this one and the generator question are, as I said, more for the classroom.

many thanx my friend this is which i am looking for.

As lyn has posted, your question is too general to give more than a general answer.

I doubt that an overall plant can be given a single classification because depending on the equipment and operating conditions in a specific area, there will be more than one classification. For example, in a coal-fired plant combustible dust is a consideration, but only in areas where dust can accumulate. In another area, there may be flammable liquids present, and that is an entirely different classification but once again only in affected areas.

Try looking up NFPA codes or Google hazardous electrical classifications for a starting point.

Different plant areas can and will be classified in different manners

Fuel tanks are one, Sub Stations are another.

Also do not confuse electrical hazardous classification with plant area classifications

Most plants being built today use gas turbines. The CT enclosure will generally be Class 1, Division 2, groups C & D. Generator (exciter housing) will probably be group B (hydrogen cooled). Fuel oil skid will be same as CT enclosure. MCC/PCC/EPE enclosures are ordinary hazard.

Again, this is for most new plants. Without specific data on your plant, we are shooting over our shoulder.

What a broad question.

It depends upon location. North Americal classification differs from pan-European classification, for example. So the best way is to receive training appropriate to the task, and appropriate to the location of the intended installation.

Broad-enough answer?
