Hazardous area in reheating furnace
Hazardous area in reheating furnace
(OP)
We are putting up an offer for a walking beam type reheating furnace. The instrumentation part of the bid document specifies that "all instruments and equipment located in hazardous locations shall be explosion-proof or intrinsically safe".
Can anyone let me know which areas (if any) might qualify as a hazardous area for installation of explosionproof or intrinsically safe equipment?

the fuel is mixed gas having calorific value of about 3000kCal/Nm3 and about 800mmWC pressure.

I would take it from your post that the owner wants all local controls to be classified as explosion proof or intrinsically safe. I would get with them and discuss the options you have available, like remote operation, or a local control booth or panel.

Certainly in Europe its all part of the AtEx regulations which will probably shed some light on what would be classified as the hazardous area in your situation
Have a look at this link on the UK Health and Safety Executive page or generally try searching for Atex regulations.
