ABSTRACT:
Apparatus comprising a metal shell enclosing a spaced adapted to be heated, low heat retention, thermal shock resistant insulation on one substantially entire surface of the metal shell, a heater to heat the space enclosed by the metal shell, a vent for heated gases from the shell-enclosed space, a conduit and nozzle to supply atomized water into the shell-enclosed space to controllably cool the shell-enclosed space, and a vent for steam from the shell-enclosed space.
A method comprising applying a low heat retention, thermal shock resistant insulation on one substantially entire surface of a metal shell enclosing a space, heating the space enclosed by the metal shell by means of hot gases with venting of the hot gases from the shell-enclosed space, supplying atomized water into the shell-enclosed heated space to controllably cool said space, and venting steam from the cooling shell-enclosed space.
