“…This was done because of the limited amount of sample generated and sample requirements for further analysis. The procedure adopted is similar to that followed by Man et al [33] in their study. About 4-5 mg of char was placed in the TGA pan for analysis.…”

“…For coal, it is assumed that fuel-bound nitrogen is distributed between the volatiles and the char during coal combustion. High temperature char-N content is the main factor limiting NO x emission reductions by deep air staging [9]. The split of nitrogen in the fuel into volatiles and char during combustion depends on the fuel type, the temperature, and the residence time.…”

“…Man et al [21] tested series of world-traded coal samples using a high temperature wire mesh apparatus (HTWM) in order to assess the relationship between high temperature (1600°C) char nitrogen content and NOx formation in Hemweg Power Station using deep furnace air staging. This studies confirmed a linear relationship between high temperature char nitrogen and NOx formation.…”

Power generation from the combustion of solid fuels has been a conventional technology for electricity production in the UK and most of the world for many decades. While the phasing out of coal as a fuel is an important aspect of the 'decarbonising' the electricity sector, the respective power plant technology could still play an important role into the future by use of abundant sources of solid biomass fuels. If such resources are to be effectively utilised, it is then necessary to accommodate the wide variation in the characteristics and behaviour of biomass fuels. Some of the key challenges in this context include: control of burn-out efficiency for different fuels; predictability of ash behaviour including operational problems and emissions arising from high ash and high potassium content fuels; the fate of fuel nitrogen content and the consequent effects on NOx emissions. This article presents an overview of these issues, their significance in the context of power plant design and operation and details of some recent research seeking to address them. Results of laboratory scale experiments showing the variation in properties and behaviour of different types of biomass fuel are also presented. These include studies on the relationship between fuel particle size and burn-out duration, gas-phase potassium release from biomass materials during combustion, variability in biomass ash composition and nitrogen release patterns from fuels in high temperature combustion.
