The ash produced in big boilers is so high in quantity, that to utilize it completely converting into useful product is not always possible. The most efficient method of disposing ash in such cases is by pumping it in form of slurry through cast basalt pipes.

systme The carrying medium is always water. Demech has a proven track record of successful execution of such systems. Flow quantity of Slurry and pressure required are the basic parameters required for designing the system.
However, these two parameters in turn depend on many other conditions like rate of ash to be disposed, pipeline distance, pipeline profile, density of slurry, viscosity of slurry etc. Moreover ash is highly abrasive and pipeline wear also needs to be considered.
A critical aspect of system is selection of slurry velocity in the pipeline which should be low to minimize abrasion but high enough to avoid settling of Ash in the pipeline.

The viscosity of slurry does not have much effect for such conditions while calculating pressure requirement, but as the slurry concentration increases the viscosity effect has a dominant effect for calculating pressure requirement. Such high pressures can be developed using piston diaphragm pumps. These pumps can develop very high pressures but are very costly and have a very high maintenance cost.
The disosal pressures result in higher power consumption though the water requirement is lower in this system. In spite of double pumping in low concentration slurry pumping, the power requirement is either low or equal. Another advantage of this systems is the easy maintenance and less cost of spares, that makes the system more viable. Ash Disposal Ash Disposal Systems.
Overview The ash produced in big boilers is so high in quantity, that to utilize it completely converting into useful product is not always possible. Demech is the only manufacturer of Cast Basalt pipes in India which are the best option for such highly abrasive ash slurry pumping.
