- a loading device of this type is known from DE 29 03 199 A. known.
- this known loading device is only the Sealed guide part, so that fine parts during operation between the rectangular cross section and penetrate its adapted guide arrangement can, which can lead to a blockage of the thrust part.
- the thrust part and the guide part are circular cylindrical trained, but it is not a seal for one of the two parts provided so that this loading device neither for incineration plants nor for gasification plants can be used because an outflow of toxic gases from the Gasification system and sucking in ambient air the incinerator are undesirable.
- the loading device has a circular cylindrical thrust piston with a correspondingly designed Guide part, but there is also none Sealing provided.
- This feeder is in set up a water reservoir from the feed hopper, from which out the fuel to be fed through a tubular Chute is conveyed diagonally upwards into the kiln. There is a certain seal through the from the Burning plug formed in the feed chute and through the water reserve, however, such an arrangement is not can be used for all combustion and gasification plants, because in most cases the fuel is humidified before being sent to the incineration or gasification plant is out of the question.
- US 3 863 779 A is a loading device known, which is a square in cross-section thrust piston has in a corresponding channel by means of a guide carriage supported by rollers is guided, however, no seal is also provided here, so that this Feeder for most combustion and Gasification plants is not suitable.
