Sulfur removal at high temperature during coal combustion
Jan 01, 2003· 1 Introduction Sulfur pollutants derived from coal combustion are harmful to the environment China is foremost in the world with total SO 2 emissions of 235 million tons in 1997 50% of this comes from power station pulverized coal fired boilers (PCFB) and 33% from industrial grate furnaces (IGF)Among the various kinds of desulfurization technologies, sulfur removal in furnaces isLuttrell adds, "If we can remove the sulfur, we can increase the value of eastern US coals" Studies at the Center for Coal and Minerals Processing showed that the patented technology can increase the retail value of coal by $23 per ton by virtue of the lower sulfur content in the coal The new process is being marketed by Virginia TechSpectrum Volume 19 Issue 01 August 29, 1996 New
Sulfur Removal in BioBriquette Combustion Using Seashell
Presently, biomass is mostly utilized as cofuel in coal combustion in view of energy diversification and emission reduction However, since the coal content of biobriquettes is high (up to 80% in this study), gas emissions such as those of SO x still occur Therefore, the introduction of SO 2 adsorbent is common in coal briquette or biobriquette combustionsulfur in the coal to fix about 6080% of the sulfur into the ash Many coal ranks can be used, including bituminous coal, subbituminous coal, and brown coal In particular, the biobriquettes produced with low grade coal containing large amounts of ash and having low calorific value combust cleanly, thus the4C3 Briquette Production Technology
