Gasifier could cut fuel cost in Bakeries

In one of   my post  on energy balance    we got  response from a gasifier  manufacturers  M/s Infinite  Energy P ltd  who have  pioneered  biomass conversion  and its application to bakery industry with processes like  biomass gassification,biomass pyrolysis , biomass briquetting and biomass drying.  I thought  to post a article on this technology .

With increase in fuel prices the bakery manufacturers  are now experimenting for low cost technology  to save fuel cost . One such  technology is  gasification . Thermal gasification is a process that converts biomass usually consisting  of  fire wood  into burnable gas or in other words to get producer gas . The producer gas  can be piped from the gasifier  to ovens which  is burnt  in specially designed burners . Wood can be replaced  with biomass briquettes , rice husk , coconut shell or any other  powdered  biomass in the process.

Gasifier  is basically  a chemical reactor  where  reactions like pyrolysis , combustion and reduction  takes place .It effectively replaces the  expensive liquid gases with  low cost  wood  without any change  in operations .

Advantage of  gasifier  are  that they  use low cost fuel such as wood and  ensures minimum energy loss . Dry gas generators  improve overall thermal efficiency .  Most of the operations have been automated except for  the biomass feeding and  ash disposal which are at present done manually . Other advantage  of such gasifiers are  its has low waste generation  and zero liquid effluent.

Gasifier process benefits

  • Reduced  energy  cost 
  • Extremely  fuel efficient  combustion with  high combustion temperature
  • No emission  of  air from  the gasifier 
  • Environment  friendly
