Often times we get questions about why someone’s well running diesel truck isn’t “rollin’ coal” or making black smoke. The simple answer is, the fact that you are not seeing any black smoke is a good thing. A properly running diesel engine should not have any smoke at all. Black smoke is an indication of restricted air among other things.View More
Pulverized coal fired boilers the total losses account to about 12 to 14 .
