    • Drawbacks GOBAR GAS ??? A G b Gobar gas plant b l t based on solid waste chokes th plant.

    • Drawbacks of GOBAR GAS ??? PPLICATION OF RENEWABLE ENERGY E However, the use of cattle dung as the feedstock is , g F the main factor limiting widespread use of methane as household fuel in rural India. Current domestic biogas plants require about 40kg of cattle dungCENTRE FOR AP (from 6 to 8 heads of cattle) every day. And because the dung has a retention period of about 40 days, the size of the biogas plant is also large.C "Restriction of space, money and absence of sufficient animals prevent many aspirants from having a biogas plant Home pages:/ : http://www.careindia.co.nr : http://www.reindia.co.nr : http://www.biogas.co.nr email : care.india@live.co.uk : Skype : care.india Mob : +9122-8097119058 / +9122-8097127783
    • Reasons for Failure Operators did not have the skills or the time required to keep a marginal system operating. PPLICATION OF RENEWABLE ENERGY Producers selected digester systems that were not E compatible with their manure handling methods. Some designer/builders sold “cookie cutter” g F designs to farms. For example, of the 30 plug flow digesters built, 19 were built by one designer and 90 percent failed.CENTRE FOR AP The designer/builders installed the wrong type of equipment, such as incorrectly sized engine- generators, generators gas transmission equipment and equipment,C electrical relays.

    • Reasons for Failure The systems became too expensive to maintain and PPLICATION OF RENEWABLE ENERGY repair because of poor system design design. E Farmers did not receive adequate training and technical support for their systems systems.

    • Reasons for SUCCESS The owner/operator realized the benefits biogas PPLICATION OF RENEWABLE ENERGY technology had to offer and wanted to make it work. E The owner/operator had some mechanical knowledge and ability and had access to technical pp support. F The designer/builder built systems that were compatible with farm operation. The owner/operator increased the profitability ofCENTRE FOR AP biogas systems through the utilization and sale of manure byproducts.

    • THE BIODIGESTER : KVIC Floating d Fl ti drum didigester E t Experiment on i t biogas technology in India began in 1937. In 1956, Jashu Bhai J Patel PPLICATION OF RENEWABLE ENERGY developed a design of floating drum E biogas plant popularly known as Gobar Gas plant. In 1962, Patels design was approved by the Khadi and Village Industries C I d t i Commission (KVIC) of I di i i f India F and this design soon became popular in India and the world. In this design, the digester chamber is made of brickCENTRE FOR AP masonry in cement mortar.

    • THE BIODIGESTER : JANTA Janata designs are relatively easy to construct and maintain because they have no moving parts and because corrosion is not a problem. One drawback is that Janata plants PPLICATION OF RENEWABLE ENERGY may require periodic cleaning due to scum build-up. As gas pressure increases in a fixed p g p E volume, the pressure pushes some of the slurry out of the digester and back into both the inlet and outlet tanks, causing the slurry level in each tank to rise.CENTRE FOR AP F BIOGAS PLANTSC B P Home pages:/ : http://www.careindia.co.nr : http://www.reindia.co.nr : http://www.biogas.co.nr email : care.india@live.co.uk : Skype : care.india Mob : +9122-8097119058 / +9122-8097127783
    • THE BIODIGESTER : CHINA FIXED DOME PPLICATION OF RENEWABLE ENERGYCENTRE FOR AP F E BIOGAS PLANTS Fixed dome Chinese model biogas plant (also called drumless digester) was built in China as early as 1936. It consists of an underground brick masonry compartment (fermentation chamber) with a dome on the top for gas storage. In this design,, the fermentation chamber ) p g g gC P and gas holder are combined as one unit. This design eliminates the use of costlier mild steel gas holder which is susceptible to corrosion. The life of fixed dome type plant is longer (from 20 to 50 years) compared to KVIC plant.

    • THE BIODIGESTER : DEENBANDHU PPLICATION OF RENEWABLE ENERGYCENTRE FOR AP F E BIOGAS PLANTS The Deenbandhu Model is a semi continuous-fed fixed dome Biogas plant. The design essentially consists of segments of two spheres of different diameters joined at their bases. The structure thus formed comprises of (i) the digester (fermentation chamber) (ii) the gas storage chamber and (iii) the empty space just above the chamber), chamber,C P gas storage chamber. The higher compressive strength of the brick masonry and concrete makes it preferable to go in for a structure that could be always kept under compression. A spherical structure loaded from the convex side will be under compression and therefore, the internal load will not have any effect on the structure structure.

The JSEI innovation could be an important E breakthrough in the use of agricultural and forest residues in biogas systems.
