A corrosion sensor for sensing corrosion in a pipeline. The sensor includes a housing and a device for joining the housing to a wall of an enclosure that receives a fluid. The sensor also includes a rupture member which extends across a portion of the housing to define a sealed chamber in the housing. The rupture member, upon rupture, provides an opening to the sealed chamber. The rupture member is formed of a material and thickness such that the rupture member will fail from corrosion before the enclosure wall will fail from corrosion. The rupture member is arranged such that fluid received in the enclosure can contact the rupture member. The sensor also includes a sensory device which is connected to the housing at the sealed chamber to signal a rupture condition of the rupture member when the sealed chamber opens.

The fuel injector nozzle for a gasifier includes a protective refractory sheath that is flush mounted at a downstream end proximate the nozzle outlet portion. The refractory insert is of annular form to surround the nozzle outlet. The annular refractory member can be a one-piece structure or a multi-segment structure of preferably not more than four pieces. Whether the annular refractory member is a one-piece structure or a multi-segment structure, it is recessed in a downstream end surface of the fuel injector nozzle and retained in the recess by locking pins or by thread-like engagement between a projection and a groove that are provided on complementary inter-engaging surfaces of the recess and the refractory member. The retaining structure provided on the annular refractory member and at the recess in which the refractory member is disposed securely maintain the annular refractory protective member in position. The enduring presence of the annular refractory member prolongs the service life of the fuel injector nozzle by protecting the vulnerable surface areas at the downstream end of the fuel injector nozzle that are close to a hot and corrosive reaction zone within the gasifier.
