The sun nicely produces biomass, but how to apply this as a profitable, sustainable and reliable co-firing fuel?!
KEMA has developed a methodology to ensure profitable, risk-optimized co-firing of biomass in coal-fired power plants.
This methodology is based on an integral co-firing chain approach. We have more than 10 years of experience in co-firing in the Dutch coal-fired power plants with a variety of fuels and co-firing systems. Our focus is on recognizing business opportunities and risk awareness by identification, managing and controlling risks associated with co-firing, thus ensuring profitable and reliable assets.
KEMA has more than 10 years of experience in the co-firing of biomass, and substantially more in relation to coal fired and other thermal power plants. We have been involved in a huge number of projects and studies for government bodies, regulators and utilities. This experience gives us the ability to ‘hit the ground running’ and to accelerate the return of value to the customer.
KEMA has gained hands-on experience through involvement with more than 50 small and full scale trials, co-firing up to 40 wt% of a variety of biomass and waste fuels with coal. In doing so, we have gained broad operational, maintenance and management experience and insight into co-firing of biomass and all associated aspects and underlying risks.
KEMA Co-firing Risk Assessment (CoRA) is based on an integral co-firing chain approach comprising:- identification, quantification and ranking of all risks within defined co-firing scenarios, accounting for:
- external factors
- company strategy and priorities
- plant-specific and technical constraints
- development of a short and long term co-firing strategy
- realization and monitoring of co-firing activities and impact
- an evaluation and feedback loop.
CoRA consists of different phases, depending on the type of support you have requested. In short: with this approach we are your “one-stop shop” for profitable, sustainable, risk-optimized and reliable co-firing activities.
