Hi all,
What is you opinion: should solar receivers, used in installations like this:

be treated as "fired" when constructed to BPVC? There is no flame, but temperatures are 1000's of C! And there is even more oxygen than in a furnace of a boiler.

Konrad and Mauro,

The answer depends on the location of installation. You got to check the laws and you will find for example
Quebec: solar heating is considered fired
New York: Fired by fuel is fired,

In many other locations there is no clear regulation. I would stick with the COde: Is it a boiler evaporating the medium or transferign the heat, or is it a process heater? In the later case, it can be treated under Section VIII.

Does this help?
Dirk

Morning,
SecVIII-1, when read "as is", doesn't have any special requirements applicable. U-1(h) mentions only direct firing from combustion of fuel (solid, liquid or gaseous). Receiving heat from the sun is not "direct", nor "combustion". Well, I don't want to go further into the original source of energy, before I will land somewhere deep in SecIII or ITER SDC-IC
Dirk, you're right, local regulations govern, as always. Apparently, the more sun people have, the less stringent regulations they have developed
