Biomass gasification

Biomass gasification Gasification provides a way to convert solid fuel into gases. Energy conversion always involves exergy and energy losses. Gaseous fuel enables use of combined cycle power generation, where both gas turbine and steam processes produce electricity. This increases energy efficiency 1,2. Higher yields of biofuel based electricity fits with national and international targets

Agreement on energy conservation and energy audits

Agreement on energy conservation and energy audits Energy audits provide valuable information on the possibilities that exist for improving energy efficiency. Finland has an official Energy Audit Programme (EAP), launched by the Ministry of Trade and Industry (MTI) already in 1992. The EAP contains management procedures, detailed guidelines, an auditor training and authorisation scheme, a

Monitoring and control

Monitoring and control The stability of processes and uniform quality of products are essential characteristics for energy efficient production. In existing processes, merely by fine-tuning the process, e.g. by introducing better control systems, energy consumption can be reduced. Online measurement and process control give accurate process information to help operating personnel avoid web breaks and

Process integration

Process integration Process integration can be defined as a collection of strategies, methods, and tools that focus on the efficient use of resources (energy, raw materials, water, and capital) on a systems level (OECD/IEA, 2000). Process integration can be used to identify an applicable flow sheet structure for integrated processes for the purpose of improving

Improvement of skills and motivation of personnel

Improvement of skills and motivation of personnel The skills and motivation of operating personnel have a great influence on the way the mill is run and equally on energy efficiency. By training the personnel to pay attention to the energy efficiency of processes and devices, good proposals for the improvement of energy use can be

Improvement of energy efficiency

Improvement of energy efficiency The reliability of processes and high production efficiency are, together with cost-effectiveness, primary objectives of industrial production. The objective of energy efficiency can either support or be contradictory to these goals. Often, an improvement in energy efficiency has followed on from an enhancement of production efficiency. For example, the reduction of

Alternative processes

Alternative processes There are other processes developed to replace the conventional evaporator, recovery boiler, causticising, lime kiln process. One driving force is the relative inefficiency of the recovery boiler. Even though the recovery boiler compares well with modern power production it is still the greatest entropy producing unit process in the kraft mill 1. Most

Torrefaction for biofuel production

Torrefaction for biofuel production Torrefied biomass for energy production is a rather new product 1. In torrefaction the wood is heated up until reactions start to occur, producing gases and changing the structure of the end product to a more brittle state (Figure 1). The highest temperatures are 200‒300 oC so pyrolysis reactions do not

Metsä Fibre Äänekoski bioproduct mill

Metsä Fibre Äänekoski bioproduct mill The new generation of pulp mill came into operation during Spring 2017. The Metsä Fibre Äänekoski bioproduct mill (Figure 1), with an investment cost of 1.2 billion euros, has the capacity of producing over 1.3 million tonnes of pulp 1,2. The annual use of softwood and hardwood is 4.7 and
