GASIFICATION-(Paralyzes)

 

 
A non-conventional, CO-Generation, Renewable energy source, a green Project. This process is a major achievement in the development of renewable energy systems. It is a thermo-chemical process that converts of renewable energy systems. It is a thermo-chemical process that converts solid waste, coal to a low heat value (LHV) gaseous fuel called “Producer Gas”. This producer gas is fuel for many different applications of shaft power, thermal power or electricity in the equipment.

Receiving GOL backing, utilizes Municipal solid

Waste as fuel, viz – waste Wood, saw dust, furniture

Waste wood, bagasse, rice husk, Coconut Shells,

Thermocol, waste plastic, rubber, tyres, leather, Coal etc.

Max.Output of a single Unit-05 Mega Watts. & Minimum Output-500 Kw.

For higher requirements multiple Units can be commissioned.


PYROLATIC GASIFIER WITH EXTENDED SHAFT

The equipment to be utilized is the new generation Gasifier a modified version developed recently to obtain clean, rich and consistent supply of producer Gas soots and smoke formed by cracking of tar with higher gasification efficiency and low coal consumption rate. Further Volatile Matter contents of the coal are converted into fix carbon which on gasification increases the calorific value of gas & reduce fuel conception and ioncreases the overall efficiency of gasification. The modified design has been developed by consistent
R & D at Bijendra by incorporating new modifications to get better viability of gasifiers .

The two in -line ESP’s or electro static precipitators help in the removal of tar  developed in the process of Pyrolysis.

COAL GASIFIER TECHNOLOGY

The Gasifier, which can gasify variety of coals & low grade fuels & produce Producer Gas. In the thermal application, the Producer Gas is burnt directly in Kiln, Furnaces, Hot Air Generator and Boiler with the help of specially design Producer Gas burners with proper mixing of combustion air to replace any type of existing liquid fuel.  

CONVENTIONAL GASIFIER TECHNOLOGY

Gasification technology has proven results of one hundred percent replacement of liquid fuels, at a net saving of almost 50 percent, in the existing fuel consumption for industries consuming from 1000 to 20,000 liters per day. (Thermal Output range 10,00,000 to 60,00,000 K.Cal/Hr) 

EXTENDED SHAFT GASIFIER TECHNOLOGY

In the new design the extended shaft is made to transform the feed coal from hopper into nearly charcoal state and removing most of its volatile matters towards faster gasification process. This down ward flow of coke carburizes the upward moving Producer Gas to enrich its calorific value.. The height of the shaft is optimized by trial & error to avoid over cooling of PG  and keeping the gas below the cracking temperature of Tar. The height of the coal bed is designed to avoid crushing of coal which leads to uneven flow of saturated air and gas and causing difficulty in rotation of the Rotary Grate. New design covers the double off-taking of PG from the extended shaft for smoother gas off-take and imparting uniform gas flow from the coal bed void spaces. Reverse flow gas wash out with recalculated phenolic water is provided for getting no effluent of any kind from the process. In the thermal application, the Producer Gas is burnt directly in Kiln, Furnaces, Hot Air Generator and Boiler with the help of specially design Gas burners for proper mixing of secondary combustion air to provide ease of combustion control.    



Feature & Advantages:

  • The producer gas generated in the Pyro – Gasifier has higher Calorific Value in the range of 1000-14000 K.Cal/NM3 which is suitable for getting high flame tempearature in the range of 1200-14000C as required by most of the thermal processes.
  • Tar Content in the  gas by pyro-gasification is minimal as the gas temperature is @ 1500C, thus delivering gas of higher calorific value to result in higher gasification  efficiency and lower coal consumption rate.
  •  Due to cleaner gas, the occurrence of choking of the burner and duck pipes is less, which results in increase in productivity and lesser cleaning interruptions in the process.
  • Minor traces of Sox / Nox formation due to low gasification & low flame temperature.
  • There is no effluent output in the process. The washing of gas is done with hot (70-800 C) re-circulated water which separates out the Tar in liquid form like FO which can be burnt in the furnace for giving extra energy to combustion.
  • The two in line ESP’s or Electro Static Precipitators help in the removal of Tar from the gas produced during the process of pyrolysis.
  • Extremely Low Particulates and smoke emission due to the complete direct firing of producer Gas & lesser than Pollution Control board norms.
  • Worldwide accepted environment friendly Renewable Energy technology.
  • Very early payback period.
