Indian Sub-bituminous and Low-Rank Coal Gasification Experiments in a Circulating Fluidized Bed Gasifier Under Air Atmosphere

摘要

This present research work aims to investigate the gasification of waste coal and sub-bituminous coal at low temperatures under air atmosphere. This paper also focus on the comparison of Indian low-rank coal and sub-bituminous coal with commercial circulating fluidized bed gasifiers. Current research shows the effective results for Indian sub-bituminous coal and low-rank coal gasification in a CFB system. Experiments conducted at different ratio of steam and coal and with different temperatures of gasifying agent. Results show that low-rank coal or waste category Indian coal can be used for gasification in any CFBs systems. This paper also focuses on different state of coal gasification technology for production of syngas use with particular attention and environmental impacts for coal gasification.
