Cofiring of Coal and Biomass in a Travelling Grate Boiler in India

Fulltext - Cofiring of Coal and Biomass in a Travelling Grate Boiler in India. Most of the industrial sources of pollution come from coal fired power plants which The generated steam has a maximum temperature and pressure of 485°C and With regard to the ash content, values for biomass are much lower that for coal.:KV Narayanan - ‎2006 - ‎:7 - ‎
