Special Issue Information

Dear Colleagues,

Striving for a minimization of non-renewable energy resources consumption and greenhouse gases (GHG) emissions is crucial from the point of view of sustainable mankind development.Reduction of fossil fuels consumption and consequent GHG emission in energy supply sector is increasingly a more and more important issue. One of the approaches aiming at this is substitution of fossil fuels with solid biomass, commonly regarded as CO2-neutral fuel. Combustion of biomass and co-firing it with fossil fuels is a popular technology across Europe and USA. It can be done in many technological configurations, where grate technology combustion, pulverised fuel combustion (PF) and fluidised bed combustion (CFB – circulating fluidised bed and BFB – bubbling fluidised bed) should be named as the most popular. Although all the listed technologies are already mature and through the very broad and detailed experience of combustion and co-firing installations, biomass co-firing ratio (determined at most by biomass share on mass or energy basis) is not unlimited for existing plants, designed primarily for coal. The potential replacement depends on technical limitations as well as limitations imposed by the authorities and financial and legal provisions. On the other hand, considering the real “carbon-neutrality” of biomass combustion, we should focus on maximisation of use of non-woody biomass, like agro-origin biomass (including straw and other residues) or energy crops.

In the planned Special Issue, we intend to focus (but not exclusively) on:

  • state-of-the-art large scale applications of biomass combustion and co-firing,
  • life cycle assesment of biomass combustion systems,
  • technological and operationsl bottlenecks of biomass combustion,
  • biomass processing and upgrading,
  • energy and ecological effects of biomass combustion,
  • biomass torrefaction for high-share co-firing ratios,
  • optimization of non-woody (agro) biomass combustion by additives.

The paper presents the combustion profile of selected fuels as a result of thermogravimetric analysis. The main purpose of this study was to investigate a mixture of different types of fuel and the influence of the use of a fuel additive on the combustion process profile. As a fuel additive, halloysite was used to investigate the thermogravimetric profiles. It was confirmed that the main combustion parameters such as ignition temperature, burnout temperature, and maximum peak temperature correlated accordingly with different combustibility indices such as the ignition index, the burnout index, and the combustion indices. Furthermore, the present study provided a comparison of selected methods for analyzing non-isothermal solid-state kinetic data and investigated the kinetics of thermal decomposition to describe the ongoing process. Two non-isothermal model methods (Kissinger and Ozawa) were used to calculate the Arrhenius parameters. The effect of heating rate and the addition of halloysite as a fuel additive on decomposition were studied. Full article
