Title: Replaceable mouth impulse burner prolonging burner life - and improving refractory
Inventor: KANERT ERICH DR-ING
IPC: F23C7/00
Filed: 1970-05-05
Abstract: Impulse burner for the partial heating of shaft furnace consists of a pipe, into which are pushed telescopically several pipes, which depending on the burning away of the mouth of the burner can be pushed forward replacing it. Provision is made for the adjustment of the air flow into the burner in accordance with the requirements arising from the effective change in burner diameter one of these being, that the temperature of the mouth region of the burner must only be slightly higher than the temp of evaporation of the fuel. The introduction of the inserts results in prolongation of the service life of the burner, whilst the possibility of adjusting the airflow helps to keep down the refractory wear near the mouth region of the burner nozzle.

Title: Dust separation from exhaust gases - continuous renewal of filter medium in filtration zone and continuous removal of dusty medium
Inventor: SGASLIK FRIEDRICH
IPC: E01C19/05
Filed: 1972-11-04
Abstract: In the separation of dust from exhaust gases using a filter medium the particles are separated from the gas, and clean gas is obtained after passage through the filter medium. The feature of the process is the continuous renewal of the filter medium in the filtration zone, and the continuous removal of dusty filter medium. Operation can be either continuous in a single unit, or dual apparatus can be used with unit filtering whilst filter medium is renewed in the other. The absence of counter-current air flow for cleaning of the medium makes the dew point temperature irrelevant.

Patent DE-2362628-A1 (DE)
Title: Tubular furnace with resistance heating - having tubes directly connected to transformer windings
Inventor: PAWLIK RUDOLF
IPC: H05B3/00
Filed: 1973-12-17
Abstract: Tubular furnace consists of tubes to which electrical connections are made dividing the tube into a series of sections. For Zn tube sections, the Zn+1 electrical connections are connected to Zn secondary windings of transformers. These are so arranged that the (Zn)th and the (Zn+1)th electrical connection are connected to the same pole. This means that the windings in adjacent sections are in fact opposed to each other. Neighbouring tubes are electrically connected in parallel. The sections are connected in pairs to transformers with two secondary windings. By generating the heat directly in the wall of the tube, the need for heat transfer between the tube and an external heating element is avoided. To achieve a given temp. in the tube (e.g. 150 degrees C) the element would have to run considerably hotter (about 1300 degrees C). Elements at this temp. are unreliable and have a very short life. Resistance heating in the tube wall is more reliable and controllable.
