Infrared radiant heater for large spaces

摘要

1. Thermal radiator for the heating of large areas or rooms with at least one radiation tube (10), on the one end of which a burner facility (20) is disposed and at the other end of which there is disposed an exhaust gas pipe (30) that can be connected to a chimney breeching, in which the radiation tube (10), within the area of the burner facility (20), is provided with a refractory insulation (50:150) for shielding against a direct flame action and against overheating and possesses a large diameter (D) suitable for the emission of long-wave thermal radiation, characterized in that a) the burner facility (20) is constructed in the form of a pressure oil nozzle burner (21) with a blower (22), b) the radiation tube (10) over its entire length (L) is provided with an insulating layer (60) which, with increasing distance from the burner facility, possesses a decreasing thickness and/or effectiveness and c) the radiation tube (10), over its entire length (L), is constructed so as to be gas-proof and in that the burner facility (20) is constructed so as to be operable within the excessive pressure ranges, while inside the radiation tube (10) and/or within the area of the exhaust gas pipe (30), a drag (170) is mounted.
