A penetration seal and its installation method for use with a pipe extending through an opening, or penetration, in a vessel, such as a boiler, containing fluid. A first collar surrounds the pipe adjacent the vessel and is in fluid communication with the opening in the vessel. A second collar has a sleeve portion engaging the exterior of the pipe and is spaced from the first collar. An insulation pillow substantially surrounds the pipe and is connected to the first and second collars. An expansion sleeve substantially surrounds the insulation pillow and is connected to the first and second collars, wherein the sleeve portion of the second collar is configured to compressively engage the exterior surface of the pipe sufficiently to frictionally fix the second sleeve against movement relative to the pipe.

An expansion joint for a solids return system includes a female joint portion, a male joint portion received by the female joint portion, the male joint portion and the female joint portion forming a lateral breach therebetween, a double rope seal positioned within the lateral breach, the double rope seal being configured to accommodate relative lateral movement between the female joint portion and the male joint portion, and an insulating pillow received about the male joint portion and abutting a distal end surface of the female joint portion, the insulating pillow being configured to accommodate relative axial movement between the female joint portion and the male joint portion.

Embodiments of the invention provide a novel band clamp insulation system for ensuring a tight insulation around a pipe during extended operation of the system and mitigating adverse effects of differential thermal expansion. The band clamp insulation system typically comprises a band clamp for securing insulation around the pipe and a securing member fixed to the pipe. The band clamp insulation system further comprises a coupling member for fastening the band clamp and the coupling member together.

Presently disclosed self-regulating thermal insulation may include one or more thermal actuators that may expand and contract in response to changes in temperature adjacent the thermal insulation, thereby automatically changing the thermal resistance of the thermal insulation. In this manner, a self-regulating thermal insulation may be configured to locally adjust in response to local changes in temperature of a part being insulated, for example, during curing or some other manufacturing process. Such self-regulating thermal insulation may be configured to respond to temperature changes without feedback control systems, power, or human intervention. One example of self-regulating thermal insulation may include a first plate, a second plate, a support structure coupling the first plate and the second plate and defining an insulation thickness therebetween, an internal partition positioned between the first plate and the second plate, and at least one thermal actuator positioned between the second plate and the internal partition.
