Burner system and a method for increasing the efficiency of a heat exchanger

摘要

The present invention is a burner system that allows ‘quasi continuous burning’ of fluids at very high temperatures by using controlled continuous pulsing explosions or detonations instead of continuous flow and thus creating pulsing pressure waves that can be easily utilised for increasing heat exchanger efficiency. After initiation the explosions or detonations are maintained by use of infrared radiation. The pulsed explosions or detonations send their shock waves directly onto the heat exchanger walls thus introducing a bigger part of energy into the heat exchanger wall then would be possible with any other method of heat exchange. In addition the kinetic energy of the negative acceleration of the mass in the explosion or detonation wave is added as additional heat introduced into the heat exchanger walls.

1. A burner system comprising a reaction chamber and at least one long, small cross-section friction channel through which at least two pressurized fluid compounds flow into said reaction chamber where they react to produce a controlled continuous sequence of pulsing detonations and/or explosions, wherein each explosion or detonation is followed by an interval during which no reaction takes place, wherein:
a) said reaction chamber of said burner system has a shape and dimensions configured such that, after each detonation and/or explosion is initiated:
i) a small part of the shock wave produced by each detonation and/or explosion is directed towards and travels into said friction channel; andii) the remainder of said shock wave strikes the interior walls of said reaction chamber causing said interior walls to emit infrared radiation, which is directed towards and focused by design at selected locations within said reaction chamber; and b) said friction channel has a shape and dimensions configured such that said small part of the shock wave produced by each detonation and/or explosion that travels into said friction channel and flows in the opposite direction to the flow of said at least two fluid compounds temporarily blocks the flow of said at least two fluid compounds into said reaction chamber thereby creating said interval until friction between said small part of the shock wave and the walls of said friction channel dissipates the energy of said small part of the shock wave in the friction channel whereupon the pressure of said at least two pressurized fluids and the vacuum created behind said shock wave of the explosion or detonation travelling in said friction channel causes said at least two fluid compounds to resume flowing into said reaction chamber, where said at least two fluid compounds pass through emitted infrared radiation until they reach the designated ignition point whereupon said focused infrared radiation ignites said two compounds.
