For an alcohol tank, is it necessary to silver solder?
Not that I have ever built one, but I would have thought just regular soft solder would be fine unless perhaps on a tank loco where there might be risk of a fire at which point the solder might melt.
You photo seems to suggest that it is on a tender and somewhat protected from risk of fire.
Certainly silver solder, or silver bearing solder, with a higher temperature than soft solder might make you feel safer.

Hi Royce,
I have only ever silver soldered 'little' parts together.
A torch is enough to get everything red hot.
So, unless it is a kiln to melt gold or something, I don't think that an oven will get hot enough for a boiler.
I was just looking at the instructions for the G1MRA 'Project' locomotive fuel tank, and they have you use copper rivets to assemble it before soldering.
Maybe you can use something like that to keep everything in alignment.
Cheers,
David
