Sommario/riassunto |
|
Putting Assessment for Learning into Practice is about the purpose of teaching and assessment as a means to ensuring deep, maximised, engaged and challenging learning. The simple message is good teaching can overcome bad testing and central to assessment for learning is empowering learners through developing learning autonomy. This means involving learners in their own learning through reflection but also as co-constructors and co-negotiators of their learning. This book is for all teachers and school leaders who are committed to ensuring learners are engaged in successful, meaningful and deep |

Sommario/riassunto |
|
This book focuses on pulverized coal particle devolatilization, ignition, alkali metal release behavior, and burnout temperature using several novel optic diagnostic methods on a Hencken multi-flat flame burner. Firstly, it presents a novel multi-filter technique to detect the CH* signal during coal ignition, which can be used to characterize the volatile release and reaction process. It then offers observations on the |

prevalent transition from heterogeneous ignition to hetero-homogeneous ignition due to ambient temperature based on visible light signal diagnostics. By utilizing the gap between the excitation energies of the gas and particle phases, a new low-intensity laser-induced breakdown spectroscopy (PS-LIBS) is developed to identify the presence of sodium in the particle or gas phase along the combustion process. For the first time, the in-situ verification of the gas phase Na release accompanying coal devolatilization is fulfilled when the ambient temperature is high enough. In fact, particle temperature plays a vital role in the coal burnout process and ash particle formation. The last part of the book uses RGB color pyrometry and the CBK model to study the char particle temperature on a Hencken burner. It offers readers valuable information on the technique of coal ignition and combustion diagnostics as well as coal combustion characteristics. |
