Industrial Solution for Biomass Torrefaction - RHC

Industrial Solution for Biomass Torrefaction
A Cmi engineered facility to tranform biomass in an improved fuel in the
range from 3t/h
What is Torrefaction ?
• Industrial Process for converting Biomass
into a fuel:
• Concentration of heat value (LHV)
•
•
•
12000 KJ/Kg for wood chips
16500-18000 KJ/Kg for pellets
21000-24000 KJ/Kg for torrefied biomass
• Homogeneous
• Stable (hydrophobic)
• Easily grindable

Timeline of CMI research on torrefaction
• 2005: First torrefaction test on CMI’s pilot plant
• 2005-2007: TorbiGaP - AgroParisTech, CEA, CIRAD, CMI, IFP, UTC
• 2009-2011: Partnership
Scientific and industrial objectives:
•
To improve scientific knowledge about torrefaction
•
To adapt and optimize CMI’s technology to torrefaction
Resources:
•
Pilot plant and instrumental means
•
Analytical facilities
•
Simulation: CFD model
R&D and experimental capacities to support and secure
upsizing of torrefaction plant to industrial scale

Adaptation and optimization
• Objectives:
 To experiment in conditions representative of industrial scale
 To test and approve innovative configurations
 To obtain reference tests and validate CFD model
• Adaptation:
 Burner
 Tightness
 Carrier gas
 Instrumentation
 More than 30 measures of temperature
 Sampling solid along the furnace
 Sampling gas along the furnace
• Improvement obtained:
 Temperature stable and controlled
 Oxygen fraction limited
 Product quality controlled

Advantages of the CMI-Nesa Solution
CMI propose a complete solution
• tested (MHF > 125 ref all uses included)
• From a recognized worldwide equipment
manufacturer
• working 8000 h/y – limited maintenance
• Long lasting equipment
• Low energy overcost compared to classical
drying and mechanical preparation
11
Summary
For forestry industry or coal fired power plants
needing an industrial scale torrefaction solution,
CMI develops a complete process based on the
MHF experience from drying to flue gas
recirculation, cleaning and energy recovery
which unlike competition comes along proven
experience in project management, equipment
delivery and commissioning.
