VGB PowerTech e.V. VGB-Standard: Fire and Explosion Protection in Biomass Fired Power Plants
VGB-S-018-00-2013-12 Sebastian Zimmerling
VGB PowerTech e.V. | SLIDE 2
Activities
� VGB is a voluntary association of power plant operators, manufacturers and supply
industry.
� We concentrate technical expertise and services for our member companies
in all areas of power and heat generation.
� We collaborate in the preparation of European and national standards and develop
our own VGB-Standards
� We initiation and co-ordinate joint R&D projects for our members
� We focus on operational safety and environmental compatibility, as well as
availability and economic efficiency

VGB PowerTech – Technical Committees
In more than 90 committees about 1,600
experts meet regularly for information exchange on all technical power plant
issues

Starting Point
Members of VGB´s European Working Group “Biomass” repeatedly reported on fires
occurring in their power plants, especially during storage and conveying of biomass.
external ignition source
self ignition
ignition by hot surfaces
ignition source unknown
VGB PowerTech e.V. | SLIDE 8
� Biomass is biological active, macro-biological and especially micro-biological
� Microbiological and chemical activities generate heat, which leads to self-heating
� Heat, that can not be dissipated can even lead to self ignition
� The higher the amount of stored biomass the lower the dissipation rate (adiabatic
boundary layer)
Challenges
VGB PowerTech e.V. | SLIDE 9
Challenges
� Biomass fuels often contain huge amounts of dust
� Biomass dusts settle on surfaces and structures
� Biomass dusts are highly flammable, e.g. by hot surfaces
� Biomass dusts can build hazardous explosive atmospheres

VGB-Standard
Conclusion
A new VGB-Standard is necessary to tackle the
challenges of storing and conveying large amounts of
biomass fuels
Outlines
� Addition to VGB-Standard R108: „Fire Protection in Power Plants”
� Explosion prevention had to be included
� Short but comprehensive “living document”
� Brief theoretical background
� Strong focus on recommendations for daily operation
� Best, to carry along during plant inspection

Structure
Basics
� What is a fire?
� What is an explosion?
� Which parameters are important for the characterisation of the fuel and its dust?
System Assessment
� Which possible hazards can be derived from the fuel properties?
� What promotes self-ignition during storage?
� Where are the risks during conveying and preparation (hot surfaces, sparks…)?

Protection against fire and explosion
� Fire risk precautions for
• Storage
• Conveying and preparation
� Protection against explosion
• Explosion prevention
• Explosion protection by construction
� Organizational measures against fire and explosion
Hints for fire fighting
� Common Measures
� Specific procedures for fire in open area storage
� Specific procedures for silo fires
