Biomass combustion in fluidized bed boilers: Potential problems and remedies
TL;DR: In this article, the authors present the major issues concerned with biomass combustion with special reference to the small scale fluidized bed systems (small to pilot scale). Problems have been identified, mechanisms explained and solutions have been indicated.

Physical characterisation and chemical composition of densified biomass fuels with regard to their combustion behaviour
Ingwald Obernberger,Gerold Thek +1 more
TL;DR: In this paper, a questionnaire survey of European producers of densified biomass fuels was performed, where the authors evaluated the quality of their products in terms of the following parameters: the dimensions of the fuels, the bulk and the particle density, the water and the ash content, the gross and the net calorific value, the abrasion, the content of starch (as an indication for the use of biological binding agents), the concentrations of C, H, N, S, Cl, K as well as of the heavy metals Cd, Pb, Zn,

The implications of chlorine-associated corrosion on the operation of biomass-fired boilers
TL;DR: In this paper, the potential corrosion problems associated with burning biomass fuels either alone or in blends with coal, for electricity production are discussed, and the most severe corrosion problems in biomass-fired systems are expected to occur due to Cl-rich deposits formed on superheater tubes.

Transformation and Release to the Gas Phase of Cl, K, and S during Combustion of Annual Biomass
TL;DR: In this paper, the transformation of inorganic constituents in annual biomass was experimentally investigated at grate-combustion conditions, and the experimental results revealed that potassium was released to the gas phase in significant amounts at combustion above 700 °C.
Journal ArticleDOI
Grate-firing of biomass for heat and power production
TL;DR: A review of the state-of-the-art knowledge on grate-fired boilers burning biomass can be found in this article, where the key elements in the firing system and the development, the important combustion mechanism, the recent breakthrough in the technology, the most pressing issues, the current research and development activities, and the critical future problems to be resolved.

The effects of chlorides, hydrogen chloride, and sulfur dioxide in the oxidation of steels below deposits
TL;DR: In this article, it was shown that the evaporation of FeCl2(g) and its outward diffusion through the scale is the rate controlling step of the active oxidation of a low alloy steel at 500°C and high alloy steels at 600 and 700°C.

Direct Observation of Alkali Vapor Release during Biomass Combustion and Gasification. 1. Application of Molecular Beam/Mass Spectrometry to Switchgrass Combustion
TL;DR: In this article, a molecular beam/mass spectrometer was used to identify alkali metal containing species released during the combustion of switchgrass at four different conditions: 1100 °C in He/O 2 -(20%), 800 °c in He 2 O 2 (20%), 1100 °c IN He O 2 2 (5%), and 1100 ×C IN HE O 2 O 3 (10%)/steam (20%).

Whitney Award Lecture—1986: Chemistry and Electrochemistry of the Hot Corrosion of Metals
TL;DR: In this article, the basicity-dependent solubilities for NiO, Co3O4, Al2O3, Fe oxides, SiO2, and Cr 2O3 in fused Na2SO4 at 1200 K were investigated.

Accelerated oxidation rate of chromium induced by sodium chloride
TL;DR: In this article, the authors measured the oxidation rate of NaCl-coated chromium over the temperature range of 823-1043 K. Although the melting point of NaCL is 1074 K, accelerated oxidation was observed at every temperature.
