摘要:
The invention relates to a steam generator (D1, D2) having a first passage, which is formed by one or more pipes (R1, R2) and through which a medium can be conducted in liquid and/or vapour form, and having a second passage (F1, F2), through which a hot gas can be conducted along the outer side of each of the pipes (R1, R2) which form the first passage. Each of the pipes (R1, R2), which form the first passage, of the steam generator (D1, D2) is surrounded by a pressure-resistant casing (M1, M2) which has a heat-insulating coating (W1, W2) on the inner side thereof and through the interior space of which the second passage (F1, F2) runs.
摘要:
The invention relates to a process for producing a synthesis gas product by catalytic steam reforming of a feed which predominantly comprises hydrogen (H2) and carbon monoxide (CO) and contains hydrocarbons (C feed), and to an apparatus for carrying out the process. The C feed (6) is mixed with steam and/or reformer gas (8) and converted into the synthesis gas product (13) in a reactor (10) by steam reforming.

摘要:
The invention relates to a burner comprising a burner head and gas supply channels arranged in the burner head. In order to improve the heat and corrosion resistance of the burner, the burner head consists of a material containing aluminium at least in the region of the outlet ends (5 and 6) of the gas supply channels (2 and 1).
摘要:
The invention relates to a device for the reactive conversion of gaseous streams at high temperatures in excess of 1000° C. Said device comprises a reaction chamber (8) with an inlet opening for the gaseous streams to be converted, in particular a burner head (2) and an outlet opening for the converted gaseous streams. In order to guarantee the highest possible conversion performance, the reaction chamber (8) has a narrow construction, extending longitudinally from the inlet opening to the outlet opening to form a controlled gaseous flow, thus preventing a circulatory flow in the reaction chamber (8). To achieve reaction conditions that are as adiabatic as possible, the reaction chamber (8) is thermally insulated with a layer (7) that has a porous foam and/or fiber structure. In the simplest embodiment, the reaction chamber (8) is cylindrical, thus achieving a tubular flow reactor construction for the entire device.
摘要:
A method and a device for the separate introduction of a fuel gas and also of an oxidizing agent into the reaction chamber of a tubular reactor, in order there to be mixed and reacted with the release of heat. Not only the fuel gas but also the oxidizing agent are introduced into the reaction chamber in each case in more than three gas jets, wherein the margin between a fuel gas jet and an oxidizing agent jet as adjacent as possible thereto, on entry into the reaction chamber, is between 2 and 500 mm, preferably between 5 and 50 mm.
摘要:
The invention relates to a burner with a burner head and burner tubes (A, I, Z), arranged in the burner head, which are made of metal and are intended for feeding at least one fuel (K) and an oxidizing agent (O) into a reaction space. At least one of the burner tubes (I) is provided with a cladding (V) which is composed of a ceramic material and entirely or partially covers the inner or the outer surface of the burner tube so that hot gas corrosion and mechanical abrasion are avoided. In order to minimize the mechanical loads acting on the cladding, the ceramic cladding (V) is connected to the metallic burner tube (I) by means of a form-fitting connection.
摘要:
The invention relates to a burner with a burner head (1) and a gas feed pipe (2) that is located in the burner head (1) and that is surrounded by an ring channel (3) for feed of another gas. In the gas feed pipe (2) and in the ring channel (3), there are means (10, 11) for producing a swirl of the gas flowing through the gas feed pipe (2) and that flowing through the ring channel (3).
