Abstract
The object is to rapidly clean-up an off-gas generated by blasting in a pressure vessel to such a level as to permit the exhaust of the off-gas. An object to be blasted is blasted in a pressure vessel to generate an off-gas, which is introduced into a combustion furnace to burning a combustible component contained in the off-gas. The off-gas after the burning in a reservoir section is stored in the reservoir section, and exhausted out of the reservoir section if a component contained in the off-gas complies a predetermined emission requirement, otherwise returned to at least one of the pressure vessel and the combustion furnace to be re-treated if the component does not comply the emission requirement.
