Abstract
The unplugging apparatus includes an annular member having a refractory ring on its inner surface. A housing is supported by the member and connected to a radially disposed conduit. A tube in the housing is guided for upward movement by the housing. A nozzle may be provided on the upper end of the tube. The tube has a reaction surface within the housing and is adapted to be projected upwardly by gas introduced into the housing from the conduit. The tube has a passage so that the gas from the housing may be discharged through the nozzle.
