Abstract:
An internal lining system (60) of an industrial chimney (70) comprises an arrangement of adhesively adhered building blocks( 40). A building block(40) for use in an internal lining system of a chimney, preferably made from closed cell foamed borosilicate glass,comprises a front face (42) and a back face (44) and side faces (46, 48, 50, 52). The front face (42) has a height (Z) and a width (X)and is spaced apart by a depth (Y) from the parallel back face(44). At least one of the side faces (46) has a first recess (54) for accommodating an adhesive, allowing to construct an internal lining system wherein the at least one side face (46)having the first recess (54) of the building blocks (40 are oriented horizontally, without horizontal joints of adhesive at the front faces(42) being present.

Abstract:
A refractory insert is provided, including a main body part having a first surface defining a first sidewall, an opposed second surface defining a second sidewall, and an outer peripheral surface separating the first and second surfaces, and a mechanical mating member provided on at least a portion of the outer peripheral surface thereof. The mechanical mating member includes a retention mechanism for controlling and retaining a position of a corresponding mating member in connection therewith.
Abstract:
A burner sub-system, a furnace comprising the same, a fuel combustion process and steam cracking process carried out in the furnace. The burner sub-system comprises a barrier wall segment (60) between the burner tip (20) and the flue-gas recirculation ("FGR") duct (40), effectively blocking direct gas flow between the burner tip and the FGR duct opening, but without encircling the whole burner tip. The presence of the partial barrier wall has the advantage of preventing the temperature inside the FGR duct from becoming too high, while achieving low NOx emissions from the combustion process without overheating the burner tip because of reduced amount of heat reflection to the burner tip compared to an annular barrier wall. The invention is particularly useful in furnaces where hydrogen-rich fuel gas is combusted.
Abstract:
Le procédé selon l'invention comprend un brûleur à prémélange constitué d'un ensemble de buses (2) de prémélange disposées circulairement selon un diamètre DB autour d'une buse centrale (4) disposé sur un axe central A au brûleur (1) et destinée à créer une flamme radiale (5) caractérisée en ce que l'ensemble des buses (2, 4) a un ratio comburant/carburant (R) compris entre 1,3 et 1,75. La flamme radiale (5) a pour mission d'assurer l'inter-allumage entre les différentes buses (2, 4) de prémélange. Une flamme annulaire est également réalisée par une combustion en prémélange afin de conserver le ratio (R) favorable à la faible production d'oxydes d'azote d'origine thermique à l'intersection de la flamme radiale et des flammes issues des buses.
Abstract:
The invention relates to a fireproof inner layer (1) for an industrial furnace wall (2), which comprises several wall elements (3), which are at least partially retained on the industrial furnace wall (2) by means of at least one retaining element (4) each, wherein the retaining element (4) has a base section (4F) and an end section (4E) connected to the base section and the retaining element (4) is fastened to the industrial furnace wall (2) in the region of the base section (4F) and has an anchor (4.1) in the region of the end section (4E), which anchor is coupled to the wall element (3) in a form-closed manner, wherein the wall element (3) has a back side (3R) facing the industrial furnace wall (2), a front side (3V) arranged opposite the back side (3R), an end face (3S) arranged at least partially between the back side (3R) and the front side (3V), and at least one cavity (3.1) for at least indirectly receiving the anchor (4.1), wherein a fireproof anchor pocket (5) is provided, which is inserted into the cavity (3.1), wherein the retaining element (4) is inserted into the anchor pocket (5) by means of at least part of the end section (4E) and/or the anchor (4.1). The invention further relates to a retaining element lining (5) designed as an anchor pocket as part of a fireproof inner layer (1).
Abstract:
Burner for conveyor gas propelled particulate solid fuel, said burner comprising a burner block (100) and an injector assembly (200), the injector assembly being at least partially surrounded by an injector passage (130) of the burner block, the injector assembly comprising an inner oxygen supply pipe (210) surrounding a fuel injector, which in turn surrounds an oxygen injector (230), each having a downstream end (211, 221, 231) on the side of the passage outlet, the inner oxygen supply pipe having a lateral surface onto which are mounted a set of lateral primary oxygen nozzles (212) for the injection of lateral jets of primary oxygen into the fuel injector with an injection orientation which follows a same sense of rotation around the longitudinal direction and which is directed towards the downstream end of the fuel injector, said lateral primary oxygen nozzles being positioned at a number of different distances from the downstream end (221) of the fuel injector.
Abstract:
The inventive subject matter is directed toward a pyrolytic waste treatment system having a pyrolysis chamber supported in a manner that causes minimal movement or flexing of the chamber as the temperature of the chamber changes. Preferred solutions utilize support structures made from materials having low coefficients of thermal expansion, and structures adapted to allow chambers to expand and contract with temperature changes.

Abstract:
The invention relates to a thermal shielding brick (1, 1A, 1B), especially for lining a combustion chamber wall. Said thermal shielding brick has a hot side (5), which can be exposed to a hot medium, a wall side (7) located opposite said hot side (5), and a peripheral side (69) that is joined to the hot side and to the wall side. A damping element (3, 3A, 3B) is placed on the peripheral side and effectively prevents fragments (81,81A) from detaching from the thermal shielding brick (1, 1A, 1B) if broken. The invention also relates to a combustion chamber having an inner combustion chamber lining, which comprises said thermal shielding bricks (1, 1A, 1B), and to a gas turbine with a combustion chamber.
