Abstract

La invención se refiere a un quemador (10; 11; 12) para calentar un espacio de calefacción (55; 55') con reducción de las emisiones de NOx. El quemador (10; 11; 12) comprende una cámara de mezcla y combustión (54; 54'), un equipo de mezcla y encendido (51) que está dispuesto en la cámara de mezcla y combustión (54; 54'), y un suministro de combustible (50) que está conectado con el equipo de mezcla y encendido (51) y está configurado para el suministro de combustible al equipo de mezcla y encendido (51). Además, está previsto un suministro de aire (30; 30') que está configurado para el suministro de al menos un flujo parcial de aire (L1) a la cámara de mezcla y combustión (54; 54'). Una abertura de cámara de combustión (53; 53') abre la cámara de mezcla y combustión (54; 54') hacia un espacio de calefacción que ha de calentarse (55; 55'). Además, están configurados agentes de control (60) configurados para el control de un flujo de combustible (B) por medio del suministro de combustible (50) y para el control de al menos un flujo de aire parcial (L1) por medio del suministro de aire (30; 30'), estando configurados el quemador (10; 11; 12) y los agentes de control (60) para el funcionamiento del quemador (10; 11; 12) con una llama estable (56; 56') que se extiende desde el equipo de mezcla y encendido (51) a través de la abertura de cámara de combustión (53; 53') hacia el espacio de calefacción (55; 55'). A este respecto, la sección transversal referida a la capacidad del quemador de la abertura de cámara de combustión (53; 53') se sitúa en el intervalo entre 1,5 mm2/kW y 10 mm2/kW.
