A line for the dip coating (200) of objects (204) operates with a known conveyor system (206). In order to avoid a collision between the objects (204) and the hard structure adjoining the movement path, a position transducer (274, 274', 275, 275', 276) measuring the absolute value is provided for each possible degree of freedom of movement of the object (204) fixed to the holding frame (212). The course of a first boundary surface or a boundary line (270), which reproduces the course of the hard structures along the movement path of the object (204), is stored in a memory. Also stored is the course of a second boundary surface or boundary line (271), which runs at a distance from the first boundary surface or boundary line (270). Finally, the course of a contour (273) which represents the course of the object (204) fixed to the holding frame (212) is also stored. The control device (232) calculates, from the signals supplied to it by the position transducers (274, 275, 276) and the other stored data, whether the contour (273) representing the object (204) fixed to the holding frame (212) intersects the second boundary surface or boundary line (271) or not and, in the first case, interrupts immediately the further movement of the object (204).

The invention describes a burner (10) for a thermal post-combustion device, which, in a known way, has a burner jet (1) arranged in a housing (12). Arranged on the end region of the housing (12) is a swirl apparatus (13), through which the exhaust gas to be purified can be made to flow. The burner jet (1) comprises an outer tube (2) and an inner tube (3), wherein it is possible for combustion gas to be made to flow through the interspace between said two tubes (2, 3) as far as an annular outlet gap (4) in the end region thereof. The flow path for the combustion gas has a bottleneck in the vicinity of the outlet gap (4). In this way, a compact flame can be achieved, the form of which can be designated "bell-shaped" and which, for a given volume, has a relatively small surface. Although, from a conventional point of view, such a flame has poor CO2 values, the swirl apparatus (13) ensures that the exhaust gas burns in the flame with very low NOx and CO values.

SYSTEM FOR COATING, IN PARTICULAR VARNISHING, OBJECTS, IN PARTICULAR VEHICLE BODIES
The invention relates to a system (1) for coating, in particular varnishing, objects, in particular vehicle bodies, having a coating cabin (2) in a known manner wherein coating material can be applied to the objects. An air stream that takes up and discharges the overspray particles of the coating material is conducted through the coating cabin (2). This air stream is conducted to an inlet opening (15) of an electrostatically operating separator (14) that is located on the underside of the separator (14). Overspray particles are separated from the air flowing upward in the separator (14) on at least one separator electrode (25) in the electrical field to at least one counter electrode device (26). The purified air leaves the separator (14) via an outlet opening (16) on its top side. The type of air flow in the separator (14) from bottom to top protects sensitive interior components of the separator (14). The strongest separation occurs in the lower region of the separator electrode (14) such that during the upward movement of the air, increasingly clean air interacts with increasingly clean regions of the separator electrode (25,, 40).

All areas (9, 11) in which the combustion process takes place have sufficient heat removed that the melting point of the ash of the waste product, particularly 70°C, is not exceeded at any point. In this manner, a fine-grained ash forms and largely mixes into the fluidized bed (9) and is easily disposed of. The useful heat is obtained partially from the flue gas arising from the combustion, and partially from the heat extracted from the combustion process for maintaining the maximum temperature.
