초록 ▼

In the case of a heat generator which essentially consists of a premix burner (100) and a flame tube (1), the hot gases (10) from the combustion in the premix burner (100) are fed into the flame tube (1), and there undergo staged post-combustion. This post-combustion takes place by means of a first post-combustion stage (11) and a second post-combustion stage (12). The air/fuel mixture (11a, 12a) is provided for each post-combustion stage (11, 12) in individual mixers (200, 300). These mixers are arranged axially with respect to the flame tube (1) and work in such a way that injection of the corresponding mixture (11a, 12a) makes it possible to obtain different combustion zones which extend in a staged sequence over the flame tube (1). By virtue of this staged post-combustion mode NOx emissions can be reduced by a factor of 5 compared to conventional techniques.

대표청구항 ▼

Device for carrying out a combustion process for atmospheric combustion systems, comprising: a premix burner comprising at least two hollow conical-section bodies disposed to define a conical hollow space having a longitudinal axis parallel to a flow direction of the burner, respective longitudinal symmetry axes of the bodies being offset with respect to one another so that mutually adjacent walls of the bodies form channels along the longitudinal direction for a tangentially directed combustion-air flow, and at least one fuel nozzle disposed to inject a fuel in the conical hollow space; a flame tube connected downstream of the premix burner so that heated gases generated in the premix burner are delivered into the flame tube, wherein the flame tube defines a plurality of post-combustion stages in a flow direction therethrough; and, at least one air/fuel mixer disposed at each post-combustion stage to form and introduce an air/fuel mixture into the flame tube.
