FIELD: chemistry. SUBSTANCE: invention relates to a method of synthesis of sulphur peroxide intended for synthesis of sulphuric acid using sulphur-containing source materials with high potential for formation of so-called wet dust. The method of synthesis includes combustion over oxygenated flow in a furnace (3). Sulphur-containing compounds form SO 2 in the supply stream. Gas is further cooled by radiation for the heat to be utilized as high-pressure gas. No less than 50% of useful power in the waste heat boiler (5) is transferred by gas and particle radiation. Additionally the process gas outflowing from the waste heat boiler is cooled in a dilution air heater. The dilution air is added to the process gas to provide sufficient oxygen for oxygenation of SO 2 into SO 3 in the SO 2 converter. The diluted process gas is let into the SO 2 converter (12) containing an array of catalyst layers. The waste heat boiler is a radiant heat exchanger in form of a construction with membrane walls, wherein a wall is a cooling surface. EFFECT: improved heat utilization, decreased deposition in the waste heat boiler and decreased occupied space of said boiler, increased turnaround cycle. 12 cl, 3 ex, 3 tbl, 6 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 744 704 C2 (51) МПК C01B 17/765 (2006.01) C01B 17/50 (2006.01) C01B 17/80 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК C01B 17/765 (2020.08); C01B 17/508 (2020.08); C01B 17/803 (2020.08); C01B 17/806 (2020.08); C01B 17/88 (2020.08) (21)(22) Заявка: 2019104749, 04.07.2017 04.07.2017 (73) Патентообладатель(и): Хальдор Топсёэ А/С (DK) Дата регистрации: 15.03.2021 21.07.2016 DK PA 2016 00439 (43) Дата публикации заявки: 21.08.2020 Бюл. № 24 (56) Список документов, цитированных в отчете о поиске: US 1405669 A, 07.02.1922.

Steam boilers

Two types of boilers for generating high pressure steam from gaseous effluents containing abrasive and corrosive solids are provided. Both types of boilers are vertical boilers of the fire-tube type with the gas flowing within the boiler tubes and with the water and steam surrounding the boiler tubes. In one type of boiler according to this invention, the solids-containing gas is downfed through the boiler tubes with the gas emerging from the tubes and impinging on a concave, conical deflector and a convex nose cone located below the deflector. The deflector and nose cone serve to disengage solids from the gas. In the other type of boiler according to the invention, the solids-containing gas first impinges on a baffle plate which serves to disengage solids from the gas. The solids flow down for removal, while the gas flows up the boiler tubes to generate steam.

Steam boiler

The present invention relates to a steam boiler of a new structure which may minimize a volume and is suitable to use a pellet for a raw material. The steam boiler in accordance with the present invention includes a heating case (20) in a housing (10) in which water is stored so that the water is heated by heat generated while the pellet is combusted in the heating case (20). Therefore, the steam boiler in the present invention may be compact in comparison with an existing steam boiler in which a water storage tank (1) and a boiler main body (2) are individually formed. The air of a high temperature generated when the pellet is combusted in the heating case (20) repetitively heating the water while passing through the water stored in the housing (10). The present invention improves thermal efficiency and minimizes exhaust resistance generated when the air passes through first and second heating pipes (40,50).

New type of boiler

Gas-fired water heater and storage cylinder - has gas tube and evacuation tube immersed in cylinder and formed within circular boundary

The water is contained within a cylindrical storage tank (1). At one end (4) is formed a horizontal tubular branch (6) with a flange. The cyylinder has inlet and outlet connections (16a,19). If the heater is to produce steam, this is drawn off through the branch (17a). The gas burner has a flange, to match that of the branch (6). Beyond the flange the burner connects into a heat exchange tube (11) which, in end elevation is maintained within the nes of a circle such that it can pass through the branch (6). The tube (11) connects to an exhaust (12) at the flange. ADVANTAGE - Heat exchanger can easily be removed for maintenance.

Steam boiler and its assembling method

按本发明在组装蒸汽锅炉时首先将锅炉支柱从下向上组装同时将收集器和其他外伸部分组装在锅炉支柱支架上。随后边缘锅炉支架盖板组装在锅炉支柱上且垂直的蒸汽锅炉围壁悬挂在锅炉支架盖板上。与此同时建立内部锅炉支架盖板并将接触加热面从下向上提升组装在内部锅炉支架盖板上。这样完备的总体在周围装置组装结束后提升到边缘锅炉支架盖板高度并将两至此还分开的锅炉支架盖板连接。最后组装垂直或倾斜敷设管子的锅炉壁包括炉腔漏斗。

Vertical heat exchanger

The invention relates to a vertical heat exchanger (1) having a heat exchange volume (2) that is bounded at opposite ends by an upper tube plate (3) and a lower tube plate (4) of the heat exchanger (1), and a homogeneous tube bundle (10), wherein the tube bundle (10) has a multiplicity of heat exchanger tubes (12) that are arranged regularly with respect to one another and extends within the heat exchange volume (2) between the lower tube plate (4) and the upper tube plate (3), wherein furthermore the heat exchanger tubes (12) can be flowed through by a first medium and at least one second medium can be arranged in the rest of the heat exchange volume (2), and wherein an exchange of heat can be carried out between the first medium and the second medium.

High-efficiency enhanced boiler

In devices known in the art, “conventional firetube” and “waste heat recovery” boilers each require many small tubes making successive passes within the boiler. In one embodiment of the invention, however, an enhanced conduit replaces numerous conventional small tubes. In some embodiments, the enhanced conduit incorporates a plurality of fins, each of which extends through a wall of the conduit. In other embodiments, the enhanced conduit incorporates a plurality of tubes along its outer surface, through which a heat transfer medium flows. Both designs enhance the heat transfer relationship between the hot fluid and the heat transfer medium by providing a continuous heat transfer relationship with the heat transfer medium, increasing the surface area involved in the heat transfer relationship and enhancing convection/conduction couples. For some applications, all of the tube banks of other devices in the art can be replaced by one continuous enhanced conduit.
