efficiency of waste reuse
Cement is the main component of concrete, which is, in turn, the
second most consumed material on earth. To reduce the costs of
fossil fuel consumption (non-renewable source), the technique of
co-processing has been employed for introducing alternative fuels
as part of the manufacturing process.They generate waste when
discarded in inappropriate places. It is evident that the cement
industry sector is highly intensive in energy consumption, and
should be considered in studies on energy planning.The ecological
analysis is done through comparison between ecological efficiency,
pollution indicator and values for CO2equivalent from cement
industry rate, before and after adoption of waste reuse.

1. The heating surface of this type employs suspension structure
which is good for absorbing boiler expansion and makes it safe in
2. The three cast-off mixed burning and blown gas waste heat boiler
uses special sealing devices to reduce boiler air leakage and
improve boiler efficiency.
3. The heating surfaces employ reasonable flue gas velocity design
to prevent soot accumulation.
4. Straight-arrangement adopted keeps the heating surface clean and
improve the heat exchange efficiency.
5. This equipment organizes flue gas dynamic field to the flow of
flue gas steady and uniform.
6. The convection tube-bank employs assembled structure with fast
installation and low cost.
