Agro-chemical-based power plant

  • An "agrochemical-based power plant" typically refers to a facility that generates electricity using agricultural waste or biomass, often in conjunction with or as a byproduct of agrochemical manufacturing processes.
  • These plants may use technologies like combined heat and power (CHP) or cogeneration to produce steam or electricity, which can then be used for in-house operations or sold to the grid. 


Function of the gasifier:

A gasifier is a key component in biomass-based or agrochemical-based power plants. Its role is to convert solid biomass (like wood chips, crop waste, etc.) into a combustible gas mixture (called syngas or producer gas) using a thermochemical process involving partial oxidation (limited oxygen).
