Document Type and Number:
Japanese Patent JPS62402
Kind Code:
B2
Abstract:
Off-gases and liquid residues containing chlorinated hydrocarbons, are subjected to joint combustion by forming a mist comprising a mixture of off-gases and atomized liquid residues, the latter being atomized by means of air and/or steam, and directing this mist into a preheated combustion chamber lined with refractory bricks. The mixture is introduced into the combustion chamber jointly with combustion air through a burner having four feed pipes arranged coaxially with respect to each other and terminating in conically tapered outlets, the three outer feed pipes defining three separate and coaxial annular zones around the innermost feed pipe. The liquid residue fed in and burnt is used in a quantity sufficient to maintain in the combustion chamber a predetermined maximum temperature which is not above the range 1200 DEG to 1800 DEG C., and which is compatible with the refractory properties of the brick lining of the combustion chamber. The resulting hot combustion gases are withdrawn from the combustion chamber, quenched with water, and hydrochloric acid is recovered from the resulting aqueous solution.
