<p>The pre-mixing burner (1) has fuel evaporated or atomized and then mixed with air prior to being fed to the interior of a cylindrical flame holder (10). The cylindrical surface of the flame holder is surrounded by a cylindrical cover (15), which has apertures (16) in its surface through which the hot combustion gases can penetrate and thus flow directly to the inner wall of the boiler. In this way, heat is emitted to the inner wall of the boiler.</p> |
