Abstract: A heat exchanger unit that includes a plurality of first heat exchanger ducts formed by a plurality of plates configured for a first flow of a coolant, a plurality of second heat exchanger ducts formed by the plurality of plates configured for a second flow to be cooled by the first flow, a first inlet for the first flow, a first outlet for the first flow, a first inlet for the second flow, and a second outlet for the second flow. The heat exchanger unit further includes an inlet chamber for the first flow from which a partial flow of the first flow is branched off, conducted through the plurality of first heat exchanger ducts and circulated within the heat exchanger unit to the first outlet.

Abstract: The invention relates to a rotor (1) with a signal transmitter mass (3), which is distributed non-uniformly in the circumferential direction (U), for a reluctance resolver (16) and also to a reluctance resolver (16) for converting a rotational value into an electrical signal based on a change of a magnetic field. In order to minimise an unbalance, generated as a result of the non-uniformly distributed signal transmitter mass (3) during operation, and wear phenomena resulting therefrom, the invention provides for the rotor (1) to have at least one non-magnetic compensating mass (4) compensating for the distribution of the total mass (2) of the rotor (1).

Abstract: The present invention relates to a system for carrying out oxygen-enhanced combustion in an industrial process wherein the industrial process, an oxygen supply system or a source of oxygen, a heat recovery network, and an alternative Rankine cycle system based on a working fluid other than steam are integrated to achieve improved throughput and efficiency, and a method for oxygen-enhanced combustion in an industrial process using said system. Examples of industrial processes include cement production, steel reheat applications, glass production, aluminum and copper melting, as well as any industrial process that uses process heater, furnaces where combustion is carried out using an oxidant stream with oxygen content higher’ than that in ambient air and up to 100%.

Abstract: In a kiln whose interior is heated by combustion with oxidant having a higher oxygen content than air, streams of staging oxidant are fed into the space between the combustion zone and the inner surface of the kiln, and the stoichiometric ratios and amounts of oxygen in the combustion zone and in the overall operation of the kiln are adjusted to provide control or reduction of NOx formation while maintaining or increasing productivity of the kiln.

Abstract: Combustion of petroleum coke using air to carry the fuel into a combustion zone and to provide a source of oxidant. Enhanced combution utilizes oxygen introduced into or proximate primary, secondary, tertiary, quaternary, or over-fire air to effect primary combustion of the fuel. Petroleum coke fuel in an oxygen supported air-petroleum coke combustion process can be used to re-power a utility boiler.
