Clinkerization - Cement Plant Optimization

Heat loss distribution across different elements can be established through heat balance and process audit of pyro section. Fuels used commonly to provide heat for the conversion processes are coal, fuel oil, and natural gas. Alternative fuels like petcoke, rubber tyres, wood chips, etc. have been introduced to economize cement making process.

Furnaces: principles of design and use - ScienceDirect

Heat Balance(and Saving) A heat balance is a convenient way of assessing the efficiency of a furnace. After carefully evaluating the above details, a heat balance can be drawn up – either in a graphical form by use of the Sankey diagram 12 or by simple tabulation. This can serve not merely as a guide to overall fuel consumption but also as a ...
