Abstract:
A burner for industrial furnace, which can be installed in a furnace (2) comprising at least one firing chamber (3), the burner comprises a main tubular body (6) provided with at least one first port (7) for the inlet of a fuel, with at least one second port (8) for the inlet of combustive agent, and with an end nozzle (15) provided with an outlet mouth (16) facing towards the firing chamber (3), and elements (12) for triggering combustion of the fuel - combustive agent mixture. The burner also comprises at least one duct (17) adapted to pick up a portion of the gases present within the firing chamber (3) and to convey them at the outlet mouth (16) of the end nozzle (15).
Abstract:
The present invention relates to a vehicle engine system (1) comprising a combustion part (2), a heat engine (3) arranged to convert heat from the combustion part (2) to kinetic energy, and an electrical generator (4) arranged to convert the kinetic energy from the heat engine (3) into electrical energy for directly or indirectly actuating propulsion means (5) of a vehicle on which the vehicle engine system (1) is arranged. The combustion part (2) comprises a metal burning unit 6 adapted to generate heat by burning of metal fuel (7), and this metal burning unit 6 comprises a metal burner (10). The combustion part (2) further comprises a metal fuel tank (8) for storing metal fuel (7) to be burned, and a metal fuel transport system (9) for transporting metal fuel (7) from the metal fuel tank (8) to the metal burner (10). The invention further relates to a vehicle comprising such a vehicle engine system (1) and to a method of driving such a vehicle.
Abstract:
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.
Abstract:
The combustor (10) includes an axially symmetric tube (12) along with means for introducing fuel (18) and air (20) into the tube. A swirler (24) is disposed within the tube to impart rotation in a first direction to the air/fuel mixture. A plurality of holes (26) downstream of the swirler are disposed around the tube and offset at an angle relative to an inward normal to the tube wall. Air is injected through the offset holes to impart rotation to the air/fuel mixture in a second direction opposite to the first direction. A combustion chamber (14) having a diameter larger than that of the tube receives and burns the air/fuel mixture from the tube.
Abstract:
Es wird eine Vorrichtung zur Wärmebehandlung von Blechbändern (6) mit wenigstens einer Strahlrohreinheit (1), die drei in einer gemeinsamen, zum Blechband (6) parallelen Ebene liegende Rohre, nämlich ein an einen Brenner anschließbares Mittelrohr (2) und zwei an beiden Enden mit dem Mittelrohr (2) über Rohrbögen (4) verbundene Außenrohre (3), aufweist, und mit einem Auflager (8) auf der dem Brenner gegenüberliegenden Seite der Strahlrohreinheit (1) für einen mit den beiden Rohrbögen (4) zwischen dem Mittelrohr (2) einerseits und den beiden Außenrohren (3) anderseits verbundenen Lagerzapfen (9) beschrieben, der axial verschiebbar in eine Zapfenaufnahme (10) des Auflagers (8) eingreift. Um vorteilhafte Konstruktionsbedingungen zu schaffen, wird vorgeschlagen, dass zwischen der Zapfenaufnahme (10) des Auflagers (8) und dem Lagerzapfen (9) ein eine Gleitschicht (15) bildender Einsatz (16) im Auflagebereich des Lagerzapfens (9) vorgesehen ist.
Abstract:
The invention relates to a heat exchanger system and to a gas-heated appliance, which is fitted with said heat exchanger, for treating, in particular cooking foodstuffs, wherein said appliance has a cooking space provided for holding the foodstuffs. A problem addressed by the invention to create a burner and heat exchanger system which is distinguished by a high. Said problem is solved according to the invention in that the burner is designed as a perforated pipe stub which is perforated even on the end side. To obtain good flame stability at in the event of a high burner overpressure and a high outflow speed, the gas outlet surface has alternating concave and convex surface sections.
Abstract:
A radiant heating tube (5) comprises a tube element that has a central section (6) and at least one recirculation section (7, 8) which adjoins the central section and forms a loop (9, 10) along with the central section. A joint bearing (23) is arranged at one end (12) of the radiant heating tube, while a sliding bearing (15) is provided at the other end (11) of the radiant heating tube, opposite the joint bearing (23). A burner (14) heats the radiant heating tube (5).
