i am using coal cobles with a calorific value of 30.1MJ/kg and obtaining an ash with a calorific value of 8.5MJ/kg. this translatates to about 70% coal utilisation. the coal is used on a manually fed fire tube boiler. how good is our performance benchmarking with other coal fired boilers?
are there any operational differences in using calcium hypochlorite as opposed to sodium hypochlorite for water treament. is it possible that calcium ions from calcium hypochlorite could significantly contribute to water hardness and the associated problem of scaling?
