Abrégé

The invention concerns a method and an arrangement for the detection of the detonation of an explosive during mining or similar. According to the method, a radio signal-based system is used that has one or several ID transmitter units (10:1-10:n) that can transmit a code that has been determined in advance, and a receiver unit (20) for the reception of a radio signal from a particular transmitter unit. Each transmitter unit is electrically passive and lacks a source of power. Each ID transmitter unit is charged during a blasting operation with the required electrical energy and activated to transmit its identification code by using a part of the energy that is released during the detonation in order to power the radio transmitter. Before a blasting operation, a report is drawn up containing primary identification, consisting of information about the identity code of each ID transmitter unit that has been associated with a charge, and after the blasting operation has been carried out a report is drawn up with secondary identification data consisting of signals received in the receiver unit (20) whose identification code from a particular ID transmitter unit constitutes a confirmation that the charge that has been associated with the same has been detonated.

The use of the combustion arrangement includes the ignition of the fuel, combustion of the fuel, and the transfer of the combustion heat to the first medium that is present at the combustion arrangement. A second medium is introduced to the inlet through an intake in the direct vicinity of the combustion arrangement, where the ignition of the fuel and the combustion of the fuel take place for the transfer of combustion heat also to the second medium. The heated first medium and the heated second medium are mixed before or during their introduction into the compartment.

The present invention relates to a process for the direct reduction of iron ore performed by means of a plant comprising a gravitational furnace (2) having at least one iron ore reduction zone (8) in the upper part thereof, and at least one carbon deposition zone (9) and one reduced metal product cooling zone (10) in the lower part thereof, and means for feeding a reducing gas mixture into the reactor in correspondence to the with the reduction zone, means for recycle exhaust or reactor off gas from the reactor to syngas and mixing the recycled gas with natural gas to form a reducing gas mixture. According to the invention a in first reformation step (5) unreacted carbon monoxide CO and steam present in the reactor off gas is reformed to carbon dioxide and hydrogen following the water gas shift reaction CO+H2O=CO2+H2, in a secondary reformation step the de-watered reactor off gas comprising mainly of carbon dioxide and hydrogen is processed to remove carbon dioxide, and in a third reformation step physical separation of both nitrogen and carbon oxide CO from the reducing syngas is carried out to bring down the levels of CO and any existing other gases in the recycled gas to as low level as possible such that recycled reducing gas is as close to pure hydrogen H2 as possible.
