Waste Heat Recovery Power Plants, contribute significantly, to the electrical energy saving (to the tune of 25%). The reduction in CO 2 emission, makes it environmental friendly. Installation of the waste heat recovery plant has to be tackled as a system approach, rather than considering cement plant and WHRPP operations, independently.
Cement is a global commodity, manufactured at thousands of plants. The industry is consolidating globally, but large international firms account for only 30% of the worldwide market. The principal and most visible market for cement is the construction industry in a multitude of applications where it is combined with water to make concrete.
species, temperatures and amounts and the Heat Balance module automatically calculates the heat and material balances using the BAL sheet. The Heat balance module updates the calculated results on the BALANCE row at the bottom of the form each time the user changes the input data.
The heat balance calculation provides a snap shot of the specific heat consumption of the kiln system with the kiln in stable operating conditions. The purpose of heat balance calculation is to:- Establish the specific heat consumption of the stably operating kiln. Yield information about where the heat losses occur in the system.
