Describe with water and without water floating drum type plant |
|
Answer» In the past, floating-drum plants were mainly built in India and are THEREFORE referred to as Indian drum BIOGAS digestors or Indian floating cover biogas digestors. Floating-drum plants are used chiefly for DIGESTING animal and human feces on a continuous-feed mode of operation, i.e. with daily input. They are used most frequently by small- to middle-sized farms (digester size: 5-15 m3) or in institutions and LARGER agro-industrial estates (digester size: 20-100 m3). A floating-drum PLANT consists of a cylindrical or dome-shaped digester and a moving, floating gas-holder, or drum. The gas-holder floats either directly in the fermenting slurry or in a separate water jacket. The drum in which the biogas collects has an internal and/or external guide frame that provides stability and keeps the drum upright. If biogas is produced, the drum moves up, if gas is consumed, the gas-holder sinks back. |
