calcium contents that were 5 times higher than the raw rice straw (2.0%). The lignin samples were combusted in a drop-tube furnace under conditions similar to a utility boiler and evaluated for slagging and fouling propensity. Tests were conducted for 1.5 to 2 hours with feed rates averaging 0.12 g/min and residence times close to 4 seconds.
It is estimated that about 3.1 million tons/year of rice straw are disposed by burning directly in the open field causing environmental problems. The present study was undertaken to assess the performance of rice straw power plant to specify the amount of the power, and GHG mitigation relative to the disposal rice-straw in energy production.

What is rice straw? Rice straw is a rice by-product produced when harvesting paddy. Each kg of milled rice produced results in roughly 0.7 - 1.4 kg of rice straw depending on varieties, cutting-height of the stubbles, and moisture content during harvest. Rice straw is separated from the grains after the plants are threshed either manually, using stationary threshers or, more recently, by
