An internal lining system of an industrial chimney includes a first building block and a second building block, each having a front face facing gas flowing through the industrial chimney; a joint of binding material configured to connect the first and second building blocks such that the front faces of the first and second building blocks are aligned; and a slot formed on the front face of the first building block, smoothly crossing the joint of binding material, and formed on the front face of the second building block; wherein the slot has a depth smaller than depths of the first and second building blocks.

The Smoke Chamber Sealing Device is a non-solely-cement method and system of sealing Smoke Chambers. Material such as metal, plastic, glass, composite, and/or any other material suitable for smoke chambers can be formed into the layers that seal smoke from going to where it is not supposed to go. One of many designs can involve installing metal walls on the inner walls of a smoke chamber, these metal walls would last much longer than cement and would be easier to work with considering the difficulties of parging a smoke chamber.

Disclosed are a flue pipe separation sensing apparatus and a boiler including the same. The flue pipe separation sensing apparatus of a boiler for sensing separation of an exhaust flue pipe that is fitted with and coupled to an exhaust adapter provided in an exhaust opening of a boiler body includes a sensing member located on an outer side of the exhaust flue pipe in a state, in which the exhaust flue pipe is coupled to the exhaust adapter, and that passes through the exhaust adapter by an elastic force and proceed into an interior of the exhaust adapter to sense the separation of the exhaust flue pipe when the exhaust flue pipe is separated from the exhaust adapter.

A joint seal system and method may include a seal and a band. The seal may be positioned between abutting flanges of two adjacent duct sections. A band may be positioned over the two flanges and the flange interface. The joint seal system and method may be configured to mitigate and/or eliminate leakage of pressure, flue gases, condensate, and/or any other fluid, gas, and/or vapor between abutting flanges of duct sections at a flange interface.

An exhaust tube holding member is supported by an exhaust pipe and holds, on an inner peripheral surface thereof, an exhaust tube to be inserted into the exhaust pipe. The exhaust tube holding member includes a first annular portion, a second annular portion, and an outward protruding portion. The first annular portion is formed with a first through hole. The second annular portion is formed with a second through hole in communication with the first through hole and having an inner diameter larger than that of the first through hole, and is connected to the first annular portion. The outward protruding portion protrudes peripherally outward from an outer peripheral surface of the second annular portion and is supported by the exhaust pipe. The inward protruding portion protrudes peripherally inward from an inner peripheral surface of the second annular portion and is supported by the exhaust pipe.

An exhaust pipe holding member includes an annular portion, an annular outward protruding portion (protruding piece), and a flange portion. The annular portion is formed with a through hole penetrating from one end through the other end. The outward protruding portion protrudes peripherally outward from the outer peripheral surface of the annular portion. The flange portion is disposed closer to one end than to the outward protruding portion, extending peripherally outward from the outer peripheral surface of the annular portion, and is configured to have a thickness greater than that of the outward protruding portion. The flange portion is formed with an annular groove surrounding the through hole.
