The most important aspect of the specification of solid fuel is the calorific value.
The higher the calorific value of the fuel more is the heat generated by its combustion. All my products have a very high cv of around 33000 kj/kg typically coal is around 28000 kj/kg and wood 6500 kj/kg
I have included the specifications of each product in the description pages.
The other important characteristic is the ash content which is a very low 3-5%.
