Method for introducing aid material into flow path of crude gas flow, involves detecting whether there is sufficient crude gas flow through filter element, where introduction of aid material is carried out into flow path of crude gas flow

摘要

The method involves detecting whether there is a sufficient crude gas flow (120) through a filter element (172). The introduction of aid material into the flow path of a crude gas flow is stopped when an insufficient crude gas flow is detected. The introduction of the aid material is carried out in the flow path of the crude gas flow. Independent claims are included for the following: (1) a device for introducing aid material into a flow path of a crude gas flow (2) a system for painting of objects, particular vehicle body.
