Process and device for applying circulating water to the riser bend walls of coke oven batteries

摘要

The invention relates to a process and device for applying circulating water to the riser bend walls of coke oven batteries via at least one nozzle, a pressure of about 1 to 3 bar being applied during the normal operating period to the riser bends via nozzles arranged vertically above the receiver connection and/or in the vicinity of the connection of the bend to the riser at the upper apex of the bend and, while the ovens are charged with coal, high pressures of more than 10 bar are applied to the nozzles located above the receiver connection for extraction of filling gas. According to the invention, it is proposed that, while the ovens are charged with coal, high pressures of more than 10 bar are applied additionally to nozzles laterally arranged on the bend in the vicinity of the riser connection for extracting the filling gas and/or during repair work in the cover region. <IMAGE>
