sulfer removal process from coal briquette

Sulfur fixation characteristics of single coal briquette

Coal briquette combustion is a typical reaction process of shrinkage particle model (Chen et al., 2003), different combustion atmospheres will appear around and inside the coal briquette during the combustion process in the furnace, which affect the sulfur fixation reaction process and products types.

Sulfur removal at high temperature during coal combustion

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 23.5 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 is

Sulfur Removal in Bio-Briquette Combustion Using Seashell

Presently, biomass is mostly utilized as co-fuel in coal combustion in view of energy diversification and emission reduction. However, since the coal content of bio-briquettes 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 bio-briquette combustion.

Luttrell adds, "If we can remove the sulfur, we can increase the value of eastern U.S. coals." Studies at the Center for Coal and Minerals Processing showed that the patented technology can increase the retail value of coal by $2-3 per ton by virtue of the lower sulfur content in the coal. The new process is being marketed by Virginia Tech

In particular, the bio-briquettes produced with low grade coal containing large amounts of ash and having low calorific value combust cleanly, thus the

Briquette Wikipedia

Coal briquettes have long been produced as a means of using up 'small coal', the finely broken coal inevitably produced during the mining process. Otherwise this is difficult to burn as it is hard to arrange adequate airflow through a fire of these small pieces; also such fuel tends to be drawn up and out of the chimney by the draught, giving visible black smoke.
