Rice Straw/Paddy Straw as fuel in Boiler
Paddy straw is being burnt in the field of Punjab and Haryana region as crop residue. It has gross calorific value (GCV) nearly 3000-3300Kcal//kg. If we compare it with coal as fuel for boiler some challenges have to overcome. New boiler technology and fuel management are required t o overcome those challenges. And it is found that this is successful ,efficient and environment friendly for power generation. } Biomass( Rice Straw) Fired Boiler } Comparison with Coal } Challenges for Biomass as Fuel } Biomass having high percentage of chlorine (.3 to 1.2%) } High percentage of Volatile Matter (VM-48-60%) } Ash is having high temperature corrosion properties on the boiler tube specially super heater tubes } Ash deposition on the Boiler tube surface } Fuel is available in seasonal so huge storage is required } Fuel management is also a big challenge ( fuel collection to storage to feeding to Boiler) } Comparison of Rice straw a...
