• MSW Processing Plant

Garbage with 40-60% moisture, depending to the season, will arrive to the drying unit. At this unit, garbage first enters into Solar-Greenhouse for drying. Solar drying in greenhouse with help of solar thermal panels, which generate hot air 20 degrees Celsius above ambient temperature, dries the garbage.
During rainy season, we cannot process the highly wet garbage and it needs more input energy for drying.
Rotary kiln is an extra drying facility, which uses the excess heat from the power plant to further dry the garbage.

Separation of metals and sand are done electromagnetically and by screening. Sand produced at this stage can be used as fertilizer.

 

Pelletization (production of pellet) is a simple compacting method; wherein pellet dye has tapering holes hence by simple protrusion method pellet is formed.

If it was required to export pellets for burning at the other locations, the pellets could be hardened further by adding additives or under high-pressure piston type briquetteing machine (this is only an additional option, not required for power plant)
Based on input garbage of 700 TPD being delivered at site, two units of Pelletisation plant (2x105) will produce 210 TPD RDF.
This environmentally friendly process is the core of our technology, which is very economical and makes us the most competitive in the world.  

• Power Plant
  
  For the Power generation, the boiler has to be designed specially to suit the combustion characteristics of RDF. 30% Auxiliary fuel such as gas, coal, rice husk etc. is needed.
  Special type of “traveling grate” is the highlight of our plant.
  Special alloy coating on the surface of boiler tubes up to 5 meter level at high temperature zone of furnace to protect from erosion and corrosion from acidic gases that may be produced during burning of RDF.  Our in house R&D has developed this.
  The bottom ash could be used as fertilizer and flying ash could be used for concrete block making. There will be a negligible amount of bottom ash and a lot of flying ash.
  If, water scarcity is there, we can provide Air-cooled Condenser in which we have very good experience.
  Assuming that we produce 6.6 MW, after internal consumption of electricity, about 5.9 MW could be exported to the grid.
  
   
• DRDF
  
  DRDF (Densified Refuse Derived Fuel) could be used in other industries such as steel mills, lankashire boilers of textile industry,              Pharmaceutical units, paper factories where they burn RDF to produce heat/steam. Although RDF burns like wood/coal, but if RDF is burned at  low temperature it may release harmful gases. Therefore it is highly recommended to prevent local people to use RDF as fuel for domestic use.
