Journal ArticleDOI
Biomass combustion technology development – It is all about chemical details
TL;DR: In this article, a review of chemical details related to biomass combustion processes is presented, where the focus is on large-scale combustion technologies for biomass and biomass derived waste fuels, either in district heating or also power production.
Journal ArticleDOI
Corrosion in biomass combustion: A materials selection analysis and its interaction with corrosion mechanisms and mitigation strategies
TL;DR: In this article, a materials selection strategy for superheater tubes used in biomass combustion, assessing its interaction with both the corrosion mechanisms and mitigation methods was used with the Ashby's approach.
Journal ArticleDOI
Heating temperature dependence of Cr(III) oxidation in the presence of alkali and alkaline earth salts and subsequent Cr(VI) leaching behavior.
TL;DR: Based on the proposed reaction mechanisms, countermeasures to prevent Cr oxidation (addition of NH4H2PO4, heating under inert atmosphere) were proposed and successfully tested for synthetic mixtures and for the case study.
Journal ArticleDOI
High temperature corrosion of superheater steels by KCl and K2CO3 under dry and wet conditions
TL;DR: In this article, the influence of both solid KCl and solid K 2 CO 3 on the oxidation behavior of a ferritic 10CrMo type steel and a nickel-based Alloy 625 type steel was investigated in the laboratory.
Journal ArticleDOI
Chlorine-induced high temperature corrosion of HVAF-sprayed Ni-based alumina and chromia forming coatings
TL;DR: Chlorine-induced corrosion of HVAF-sprayed Ni21Cr and Ni5Al coatings was investigated in 5 vol. as discussed by the authors with and without KCl at 600 °C up to 168 h.

SGTE data for pure elements
TL;DR: In this article, the authors present the data for the condensed phases of 78 elements as currently used by SGTE (Scientific Group Thermodata Europe) as a sound basis for the critical assessment of thermodynamic data, thereby, perhaps, limiting unnecessary duplication of effort.

TL;DR: Emphasis is placed on the new databases and the calculation and manipulation of phase diagrams and complex phase equilibria in the FactSage thermochemical software and databases.
Journal ArticleDOI
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.
Journal ArticleDOI
Utilizing biomass and waste for power production—a decade of contributing to the understanding, interpretation and analysis of deposits and corrosion products
TL;DR: In this article, the authors provide an overview of the experience gained on ash, deposit and corrosion formation in thermal fuel conversion systems fired with solid non-fossil fuels, and focus attention on how these results fit into our current understanding of this subject.

Deposition of potassium salts on heat transfer surfaces in straw-fired boilers: a pilot-scale study
TL;DR: In this paper, the fate of inorganic salts in straw-firing combustion systems was studied in Sandia's multifuel combustor and the deposition of potassium, chlorine, and sulphur and the sulphation of potassium chloride to potassium sulphate.
