Title: Process and plant for the reduction of nitrogen oxides emission in flue gases and furnace plants
IPC: B01D53/86
Filed: 1983-07-20
Abstract: The process and plant for the reduction of nitrogen oxides emissions in flue gases of furnace plants have a first furnace plant operated with an air excess of e.g. 15% and a second furnace plant, in which afterburning is carried out in the stoichiometric range with consumption of the residual oxygen. The flue gases coming from the second furnace plant no longer contain free oxygen, but contain the pollutants: uncombusted hydrocarbons, carbon monoxide, nitrogen oxides, sulphur dioxide and sulphur trioxide. The first-mentioned pollutants - uncombusted hydrocarbons, carbon monoxide and nitrogen oxides - are converted on a multifunctional catalyst to carbon dioxide, water vapour and nitrogen. The sulphur is removed from the flue gases in a flue gas desulphurisation plant. The catalytic conversion of the nitrogen oxides takes place without additives, so that the operating costs are low. Furthermore the capital costs are not as high as with conventional plants for the reduction of nitrogen oxide emissions, since the first furnace plant has only to be designed for a thermal output which corresponds to 85% of the required total output, while the second furnace plant supplies the remaining 15% of the required thermal output. The efficiency of the plant is raised since the flue gas stream is smaller, at the same total heat output, and the flue gas losses are reduced.

Title: Method of reprocessing metal dusts or chips and/or metal oxide dusts or chips, in particular grinding dusts
Inventor: HANS WALTER ING
IPC: C22B7/00
Filed: 1983-11-03
Abstract: For reprocessing metal dusts or chips and/or metal oxide dusts or chips such as, for example, grinding dusts, calcium carbonate in a quantity from 10 to 20% by weight is admixed to the dusts or chips to be reprocessed. This admixing can be carried out after a low-temperature carbonisation of the feed material at 200 to 400 DEG C in order to separate off oils and greases, whereupon the resulting mixture is heated to a temperature from 950 to 1100 DEG C and held for 30 minutes to 3 hours at the end temperature. The heating up to the end temperature is here carried out in an advantageous manner at a rate of 10 to 25 DEG C/minute. After the holding time, the heated mixture can be quenched with cold water, whereupon leaching with water takes place, to which sodium carbonate can be added in quantities from 5 to 15% by weight. The leaching can be carried out at elevated temperature and under superatmospheric pressure, whereupon the residue remaining after the leaching can be mixed again with calcium carbonate, roasted once more and then leached.

Title: Cleaning carriage for ship's sides
Inventor: FIEDLER ARNO ING GRAD
IPC: B63B59/08
Filed: 1984-09-22
Abstract: Method for cleaning the side wall surfaces of submarines on both sides of seagoing ships while under way. The ship's speed decreases, i.e. the resistance increases, due to algae and barnacle fouling. The object of the device is to employ onboard means in order to remove this fouling, which frequently forms suddenly and unforeseeably. The carriage, which has runners running in forwards, is, on the one hand, pressed against the ship's side by the slipstream impinging on the inclined surfaces and, on the other hand, driven alternately upwards and downwards with the aid of a rudder (see sketch with plan view and side view). The carriage is retained by a retaining cable which extends around the ship's bow, and paid out astern in centimetres after each operation. The runners of the carriage can be arranged permanently or exchangeably, and additionally be provided with cleaning apparatuses such as rotating or fixed brushes, etc. The device is to be handy and not too heavy. Many ways are possible for automatic, or else automatable operation and height control, and for paying out astern. <IMAGE>

Title: Television camera for observing furnaces
Inventor: SEITZ GERHARD
IPC: G02B27/00
Filed: 1984-10-05
Abstract: Television cameras are known whose objective and recording tube are accommodated in a cooled housing. A viewing opening, which is located in the centre of an outlet funnel, is provided on the tip of the housing which projects into the furnace which is to be observed. In order to keep it free of ash and dust particles, compressed air is blown through it. However, this does not reliably prevent dust and ash particles being deposited on the outlet funnel and the field of view of the camera being constricted. According to the present invention, this is prevented in that an annular groove (6) is incorporated in the wall (5) of the outlet funnel, into which channels (7, 8, 9, 10) open from the interior of the camera housing. Said channels are set up such that the compressed air flows into the annular groove from the camera housing with a component tangential with respect to the annular groove (6), rotates in the said groove and flows along the wall (5) of the outlet funnel in a rotating manner. The invention is used in the case of furnace-probe cameras. <IMAGE>

Abstract: In a process for producing a fuel comparable with heavy fuel oil, using heavy residues from crude oil processing, it is proposed to mix the residual oils originating from crude oil with distillate oils produced from coal. Owing to the lower sulphur content, the relatively low viscosity and the high aromatic content of the distillates originating from coal, a stable homogeneous low-sulphur fuel is formed which can readily be accommodated by the market as a substitute for heavy fuel oil.
