Abstract

The lock container is connected to a reactor, which serves to gasify or to combust solid fuels. The lock container serves to remove ash from the reactor. A pressure of at least 2 bars prevails in the reactor. The lock container is pressurized and pressure-relieved in alternation. The pressure relief line communicates with a filter element, which is permeable to gas and substantially impermeable to solids and is disposed within the lock container. When the lock container is filled to the usual level during a pressure relief, at least one half of the filter element is surrounded by ash. The filter element may be tubular.
