Title: Sulphur di:oxide removal from steam boiler stack gas - by parallel wet and dry absorbers to give combined prod. above dew point
Inventor: HOELTER HEINZ ING GRAD
IPC: B01D53/50
Filed: 1980-08-21
Abstract: In a process for the desulphurisation of stack gas from a power station boiler, 80-90% of the gas is taken at about 130 deg.C and wet purified and the remainder taken at about 400 deg.C and purified dry (e.g. with a CaCO3 bed followed by an electrofilter). The two streams are then mixed in adjusted proportions to give a stream at about 90-100 deg.C, i.e. above the dewpoint, which is sent to the stack. The system is useful where the SO2 loading is relatively low. The deg. of desulphurisation satisfies the regulations without the need to reheat the stream purified in the wet way, as in prior art.

Title: Coke quenching dust extractor - with three differently curved sections on parallel extractor plates
Inventor: REGEHR ULRICH DR ING
IPC: C10B39/08
Filed: 1980-12-09
Abstract: A dust extraction system for the quenching vapours from coke quenching towers uses an array of parallel dust extractor plates which are arranged in the tower chimney in vertical planes. In asection in the flow direction, each extractor plate consists of at least three curved stretches of different survature, with an apex and a trough separating them, also a fin forming a trap chamber for dust. This ensures that dust particles, once collected, are deposited in traps and not raised again, thus lowering the residual dust content in the emitted gases to below the present 50 g per tonne of quenched coke.

Patent DE-3108452-A1 (DE)
Title: Oil/gas heating boiler
Inventor: THUEMMLER SIEGFRIED
IPC: F24H1/28
Filed: 1981-03-06
Abstract: An oil/gas heating boiler having a combustion chamber which is directly arranged in the water chamber and a multiplicity of exhaust pipes which are guided through the water chamber and open out at one end into a flue discharge pipe, is to be improved by making almost complete utilisation of the heat energy available while keeping overall length low. To this end, the combustion chamber is completely closed on all sides except its bottom, which is situated opposite the burner connection side. Starting from a plurality of bottom apertures, deflection pipes having a larger cross-section than the exhaust pipes are guided to an annular space which surrounds the combustion chamber on the burner connection side and in which the exhaust pipes open out as well. This ensures that three regions are available for the transfer of heat. As a result, the temperature of the exhaust gas is much lower when it enters the exhaust pipes than is the case in previously known designs of heating boilers. <IMAGE>

Patent DE-3127606-A1 (DE)
Title: Protective-gas furnace with separate gas supply
Inventor: KOERTVELYESSY LASZLO VON DIPL
IPC: F27B17/00
Filed: 1981-07-13
Abstract: Protective-gas furnaces are normally supplied with gas by a pipe. Through this pipe, a number of gas components pass into the furnace interior and protect the charge. In many protective-gas furnaces, hydrogen - one of the most important protection components - also reaches the heat insulation and reduces its insulating effect greatly. The vapour emissions from the charge and water vapour also are precipitated in the large-area heat insulation and reduce the heat-insulating effect. During subsequent heat treatments, these precipitations can exert a harmful effect on the charge, and also extend the conditioning time. In the protective-gas furnaces which have been built according to the invention, the protective-gas components are guided into the furnace separately: nitrogen and other not very heat-conducting gases directly into the heat insulation (Fig. 2) and hydrogen and hydrogen-containing gases by the conventional path into the heating chamber. The advantages of the new furnaces are: better heat insulation, more rapid heat treatment by the nitrogen which additionally protects the ceramic fibres against the destructive effect of the reducing gases. <IMAGE>

This pulse sequence is integrated in the evaluating stage (26) and indicated. The device can be implemented with little expenditure and is distinguished by good measuring accuracy. <IMAGE>
Patent DE-3133762-A1 (DE)
Title: Heating appliance for sheet-like hand tools, especially wetting-off irons for leatherware production
Inventor: GROSSMANN PETER
IPC: C14B1/56
Filed: 1981-08-26
Abstract: The invention relates to a heating appliance for sheet-like hand tools, especially wetting-off irons for leatherware production, with an electrically heated bearing plate. The disadvantage of the known heating appliances for this purpose is that they have a very high electrical power requirement, since they radiate heat to all sides in an unimpeded manner. The result of this is, also, that burns occur on the hand because of these highly heated and easily accessible bearing plates. A third disadvantage is that the poor heat transmission from the heated bearing plate to the wetting-off iron necessitates increased heating times. These disadvantages are eliminated, according to the invention, in that a further clamping plate of approximately the same shape and dimensions, having high thermal conductivity and moving back resiliently, is arranged above the bearing plate, and the two plates are accommodated in a container lined with heat-insulating material, for example glass wool, having a lateral orifice.
