Actually, this is not washing, but desinsection of clothes.
Barrel is known as "partisan desinsection barrel", or just "partisan barrel" - it has water in bottom, upper part with wooden holders for clothes, and fire is heated below. Hot steam would (hopefully) kill ticks, which spread typhoid fever.
Very important during partisan war, since risk of infection was high.
