Biomass energy plant key features
 Pyrolysis and Gasification - complete combustion
 High efficiency of energy recovery without auxiliary fuel
 Wide range of feed stock
 Manage low quality wastes (high in moisture)
 Easy operation with complete automation systemfeed
 Residents considered system (compression packaging to minimize
odor)
 Modular system to increase capacity
Business
 Gasification converts hydrocarbons such as coal, petroleum coke
(petcoke), biomass or various wastes to a synthesis gas (syngas).
 Gasification produces the building blocks for a range of high-value
products from a variety of low-value feedstocks.

Why Kentec?
 Secondary Chamber
 Combustion control
Depends on energy demand, automatically controls the gasifier combustion
 Energy control
Energy generation can be controlled from 30% to 120% (stoker type cannot run
with 30% output)
 Emission control
Automatically controls the emission
 Oxygen control
Controls oxygen level (6-10%) by mixing emission gas to control temperature and
oxygen
 Nozzles
Multi step injection nozzle to control oxygen and temperature for gasification
Why Kentec?
320 injection nozzles to control oxygen level
