A method for accommodating thermal expansion of a heater in a formation includes flowing a heat transfer fluid through a conduit to provide heat to the formation and providing substantially constant tension to an end portion of the conduit that extends outside the formation. At least a portion of the end portion of the conduit is wound around a movable wheel used to apply tension to the conduit.

Catalytic cracking riser reactor extending between an inlet for hydrocarbonaceous feed and catalyst particles and an outlet for discharging cracked products and spent catalyst particles, which riser reactor has been provided with at least one contacting device, wherein the contacting device comprises a composite of refractory material and a metal structure, which metal structure is connected to the outer wall of the riser reactor. If more contacting devices have been provided, they are preferably axially spaced apart and are disposed along the inner surface of the riser reactor.

A protective shield for protecting a feed nozzle encloses, not only the circumference of the feed nozzle, but also encloses and protects the end of the feed nozzle. The protective shield includes an open portion in its end which corresponds to, and surrounds the slit in the end of the feed nozzle. Optimal shape of the open portion is determined by spray visualization tests.
