Low sulphur content is an advantage from an environmental perspective as it results in lower sulphur dioxide emissions. The high ash fusion temperature means that the ash melts at a higher temperature, but if furnace temperatures exceed this point, it can form slag, which sticks to boiler tubes.<br \/>\n<\/section>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following is\/are the characteristic\/characteristics of Indian coal?
