Abstract

Karıştırma cihazı, bir karıştırma lülesine (1) özellikle, bir gaz beslemesi (4, 5) olan, her durumda hava ileten iki kanalına (2,3), kapağı (9) içeren bir kapatma ünitesine (6) sahip bir ventüri lülesine sahiptir. Kapatma ünitesi, kapağın sondaki hava kanalının veya sondaki hava beslemesinin düşük hava kütle akış oranları ile işlem sırasında kapalı pozisyonda kapatacağı şekilde tasarlanmaktadır. Düşük hava akış oranı ve yüksek hava akış oranı arasındaki geçiş bölgesindeki sondaki gaz beslemesi bölgesindeki hava hızı, yanıcı gaz hava karışımının zenginleştirilmesinin mümkün olmayacağı kadar düşüktür. Bir bağımsız istem karıştırma cihazının çalıştırılması için yöntemle ilgili olarak dahil edilmiştir.The mixing device has a mixing nozzle (1), in particular a venturi nozzle with a gas supply (4, 5), two channels (2, 3) that convey air in each case, a closing unit (6) comprising a cover (9). The closing unit is designed so that the trailing air duct or the trailing air supply of the cap closes in the closed position during operation with low air mass flow rates. The air velocity in the trailing gas supply zone in the transition zone between low air flow rate and high air flow rate is so low that it is not possible to enrich the combustible gas-air mixture. An independent request is included in relation to the method for operating the mixing device.
