Composite curves are used to simultaneously visualize hot streams, cold streams and the heat transfer potential between them on the same graph. It is a graphical technique for determining the heat cascade. In each temperature interval (i in the hot stream scale and j in the cold stream scale) (we use the original temperature scale), the total heat power is calculated separately for …

In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill or ball mill, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.

The overall mass balance equation is: m1+ m2= m3 The total solids balance equation is : m1x1+ m2x2= m3x3 The total water balance equation is : m1(1-x1) + m2(1-x2) = m3(1-x3) The total water balance equation is however NOT a totally new equation. It can be obtained by subtracting the total solids balance equation from the overall mass balance

The law of conservation of mass leads to what is called a mass or a material balance. Mass In = Mass Out + Mass Stored Raw Materials = Products + Wastes + Stored Materials. Σm R = Σm P + Σm W + Σm S (where Σ (sigma) denotes the sum of all terms). Σm R = Σm R1 + Σm R2 + Σm R3 = Total Raw Materials Σm P = Σm p1 + Σm P2 + Σm P3 ...

mass balance is based on a number of user specified parameters as well as chemical relations found in the literature. A general method to approach the different concentrations and mass flows when constructing a WinGEMS block is also included in the report. In the energy balance the fuel consumption of the lime kiln is calculated.

Heat transfer is dependent on the mass flow of hot gases, mass flow of water or steam, temperature difference and surface area. A single-pressure HRSG can recover heat up to a specific level. If more heat is to be recovered, then the area of the heat exchanger increases, which soon becomes economically unfeasible.

For one-dimensional heat conduction (temperature depending on one variable only), we can devise a basic description of the process. The first law in control volume form (steady flow energy equation) with no shaft work and no mass flow reduces to the statement that ΣQ& for all surfaces = 0 (no heat transfer on top or bottom of figure 2.2).
