Biomass cofiring is widely considered as the most costefficient and easily deployed way for mitigating the CO 2 emissions from the coal power sector. Apart from policy and market benefits and bottlenecks, the implementation of cofiring in a coalfired power plant is affected by several technical and environmental concerns.

1 This fact sheet is focused on topping cycle CHP where fuel is first used to generate power. In a bottoming cycle CHP system, also referred to as "waste heat to power," fuel is first used to provide thermal input to a furnace or other industrial process and heat rejected from the furnace or process is then used for electricity production.

In this study, the cocombustion characteristics of coal and biomass blends (20, 40, 60, 80, and 100 wt%) were investigated by thermogravimetric analysis. All the samples were operated under an oxidative atmosphere, with a heating rate of 20 C/min. The reaction stages, ignition and burnout temperature, maximum weight loss rate, and different combustion indices were determined. When the ...

Introduction and Basic Principles. Blending of alternative coals is the backbone of the fuel blending practice. It is estimated that blends of coals are more commonly combusted or gasified than single coals in commercial applications. It dwarfs the practices of blending coals with biomass or wastebased fuels.

The first one is blending in coal beds. In this method, blending takes place during reclamation with homogenisation at transfer points. The advantage of this methodology is that blending takes place at coal handling plant (CHP) transfer points. However, this process has disadvantages as the entire coal needs to be stacked first and CHPs are ...
