Problems solved by technology

Such regenerators achieve efficiencies of up to 90%, but due to the necessary alternating operation of the two regenerators and therefore due to the continuous inversion, this leads to increased installation and control costs

Embodiment Construction

[0026] figure 1 A heat exchanger 1 is shown in , which serves to heat the furnace chamber 2 and which is arranged for this purpose in a perforation of the furnace wall 3 . The recuperative burner has a burner head 4 for supplying combustion air and fuel and for discharging exhaust gases. For this, set at the burner head 4 - Gas connection 5, heating-gas connection 6, - Air connection 7, heating-air connection 8 and exhaust gas connection 9 for gas discharge. - Gas connections 5 and - Air connection 7 for supplying fuel and air in liquid or vapor form or gaseous form to operate the recuperative burner 1 with flameless oxidation in the furnace 2 . The heat-gas connection 6 and the heat-air connection 8 are used to ignite the combustion chamber 10 in the heat exchange burner 1 .

[0027] The combustion chamber 10 is surrounded by a tube 11 which preferably narrows on the furnace side and which is held on one side on a flange plate 12 . The flange plate 12 is optionally ...

Abstract

The invention relates to a robust, highly effective recuperator burner. Said burner comprises at least optionally a combustion chamber for heating operation and is otherwise configured for FLOX TM operation. Heat exchanger tubes (16) are provided for preheating combustion air with the recuperator (30) by means of exhaust gas heat in counterflow, having a flattened gap cross section (34) in a heat transfer segment (31) and comprising a nozzle cross section (35) deviating from the gap cross section (34) on the end (33) thereof facing the volume (2).

Description

technical field [0001] The invention relates to a recuperative burner for heating a volume, such as the interior of a furnace or injection tube. Background technique [0002] Regeneration burners are used, for example, for the direct or indirect heating of industrial furnaces. On direct heating, oxidation of the fuel occurs in the furnace. In the case of indirect heating, combustion takes place, for example by means of injection tubes, in a tube (injection tube) which extends into the furnace but is closed relative to the furnace, whereby the tube is heated and emits thermal radiation. [0003] An example of a recuperative burner with or without injection pipes can be obtained from EP 0685683B1. The heat exchanger is located in the furnace wall and has a typical length of 400 mm and a diameter of 100-300 mm depending on the furnace power. The heat exchanger consists of ribbed segments made of heat-resistant cast steel or ceramic. To reduce the generation of nitrogen oxid...
