Fly ash generation and collection

The fly ash produced from the burning of pulverized coal in a coal-fired boiler. Typically, coal is pulverized and blown with air into the boiler's combustion chamber. Where it ignites immediately generating heat and producing a molten mineral residue. Boiler tubes extract heat from the boiler, cooling the flue gas which causes the molten mineral residue to harden and form ash (Figure 1).

Modeling for the Steady State Production of Large Open Cast Mines- Case Study

When mining company gets the lease of a mineral deposit, the difficult is then how to mine and process that deposit the optimum way. The main problem facing managers or engineers who must select on equipment selection, mine plant site and long range scheduling is how one can optimize a property not only in terms of efficiency but also as to project duration.
