摘要： A combustion system, such as a recuperator in a furnace, has a combustion chamber, a burner which communicates with the combustion chamber and tends in operation to produce acoustic waves leading to the development of vibrations, and a conduit communicating with the burner and supplying thereto a stream of fuel fluid. The development of the waves and vibrations is precluded by providing in the conduit upstream of the burner a compartment having a volume equal to forty times the product of the cross-sectional area and the diameter of the conduit so that the acoustical waves originating in the burner are reflected, and the conduit is further intermediate the burner and the compartment so constructed as to be of unobstructed cross-section and has a length equal to substantially one-quarter of the wave length of sound waves which would develop if the vibrations were allowed to occur.

摘要： A burner includes a central burner duct for passing combustion gas therethrough and an outer annular duct for the passage of combustion air and coaxial to the central burner duct. The ducts open or join at an opening area, upstream of which are one or two areas where the combustion gas and air are combined or brought together and mixed. A disk-shaped mixing element is positioned within the opening area centrally thereof and downstream of the first combination area and adjacent the second combination area. The mixing element has extending therethrough substantially in the direction of flow, a ring of separate passages.

摘要： A method for dismantling a furnace having a multilayered refractory structure including: a furnace shell; a containing layer that is formed of a containing refractory that contains asbestos, and covers the inner side of the furnace shell; and a multilayered non-containing layer that is formed of a non-containing refractory that contains no asbestos, and covers the inner side of the containing layer, the method includes: a primary dismantling process; and a secondary dismantling process conducted after the primary dismantling process. In the primary dismantling process, the non-containing layer is dismantled from a furnace-core side thereof but the containing layer and at least one layer of the layers forming the non-containing layer, which is in contact with the containing layer, are left as a remnant. In the secondary dismantling process, the remnant is dismantled while asbestos measures are implemented.

摘要： A combustion chamber wall is hollow, has a first surface and a second surface and includes a plurality of polyhedron shaped chambers defined by a matrix of integral interconnected walls. The walls of the chambers in a first layer define the first surface of the combustion chamber wall and the walls of the chambers in a third layer define the second surface of the combustion chamber wall. The chambers are fluidly interconnected by apertures extending through the integral interconnected walls of the chambers for the flow of coolant there-between. The walls of the chambers in the first layer have apertures extending there-through to supply coolant into the first layer and the walls of the chambers in the third layer have apertures extending there-through to supply coolant from the third layer into the combustion chamber. The combustion chamber wall is manufactured by additive layer manufacture.

摘要： A method for heating a blast furnace stove by combusting in a stable, visible flame a fuel with a lower heating value (LHV) of 9 MJ/Nm3 or less in a combustion region, arranged in a combustion chamber in the stove, and causing the combustion gases to flow through and thereby heat refractory material in the stove, wherein the fuel is combusted with an oxidant comprising at least 85% oxygen, and combustion gases are caused to be recirculated into the combustion zone and thereby dilute the mixture of fuel and oxidant therein sufficiently for the flame not to damage the refactory material.
