The kiln has an operation capacity of 90 t/h and upper bound of 110 t/h. A total of 57 t/h of the clinker is produced inside the kiln. For the heating of the raw mill, kiln raw meal, and a coal mill, hot flue gases from the kiln are deployed. Gases exit from a preheating tower with a temperature at about 370°C.

In an effort to reduce carbon dioxide emissions, Black Dog is one of the latest power plants to convert from coal to natural gas. The process — expected to cost 100 million — began in 1999, when two units were replaced with natural gas. The most visible changes started in July 2018, when Veit Company, a Minneapolisbased specialty ...
