“…It is seen that straws from rye, oat and barley, with high contents of K 2 O have much lower melting temperatures compared to the wheat straw, which have lower content of K 2 O. If no experimental data of ash melting behavior is available, molar ratio of (Si+P+K)/(Ca+Mg) used in [11] gives first information ash melting tendencies. It has been proved to be more accurate than well-known Si/(Ca+Mg) ratio, especially for P-rich fuels (Fig.…”

“…Combustion characteristics of miscanthus are also presented in [9] and for Miscanthus x giganteus in [10], where special attention is given to optimization of the harvest time. Ash composition, as the most important parameter while designing the combustion system, is analysed in [11] and [12], whereas in [13] ash melting behaviour is investigated in detail.…”

“…First involves intelligent fuel blending in order to overcome ash and emissions related problems. Authors in [14] propose blending it with coal while new investigations [11] found that blending it with peat also yields positive results. Second possibility involves the new cost-effective design solutions for high ash biomass combustion systems.…”

SummaryBiomass is one of the oldest energy source known to mankind. Progress made so far in understanding of a rather complex direct combustion process allowed for a constant technology development. Increasingly stringent environmental requirements of the EU, especially in terms of the pollutant emissions, require development of new design solutions of the combustion system for residential hot water boilers fuelled by some form of solid biomass. The emissions are becoming even greater problem if, various residues from agricultural production are used instead of a wooden biomass, as they are becoming more desirable fuel due to their lower cost.In this paper, various issues related to the combustion of agricultural biomass are discussed. Attention is given to the problems associated with high volatile matter contents, presence of nitrogen, sulphur, chlorine and low ash melting temperatures. At the end, novel design modifications of a conventional residential biomass combustion system are proposed, as the well-known methodologies for combustion and emissions control applied in industrialscale boilers are in most cases not suitable for small-scale units.

“…But it is possible to estimate emissions of NO x and PM on the basis of an 'additivity' rule, that is, the emission of the blend is approximately the sum of the emissions of the individual components on a pro rata basis (Sommersacher et al, 2015;Mitchell et al, 2015).…”

“…As a result, the variability in conservation sites gives rise to a wide variety of different biomass forms that could be utilised in the production of bioheat (Kuhlman et al, 2013;Kask et al, 2013Kask et al, /2014Wichtmann et al, 2014;Ranjitkar et al, 2014;Sommersacher et al, 2015). Consequently, conservation management practices can produce a considerable amount of biomass wastes that are currently disposed of by open burning.…”

A number of countries have introduced energy policies to reduce the emission of carbon dioxide which, in the case of bio-heat, has resulted in increased use of small wood burning stoves and boilers, particularly in Europe. There are issues surrounding the supply of sustainable wood feedstock, prompting a desire to utilise local biomass resources. This includes biomass generated through the management of natural woodlands in nature reserves and conservation areas. These management practices can also extend to other areas, such as raised bog wildernesses and estuary Reed beds. We term the biomass from this resource as conservation biomass. This study is concerned with the viability of this resource as a fuel within the United Kingdom, and combustion tests were carried out using a small domestic stove. It was concluded that there is as much as 500kty(-1) that could be used in this way.
