To calculate the total energy used to heat and melt scrap steel we will assume that the steel is pure iron (Fe). During the melting process, iron's specific heat varies greatly from an ambient temperature of 298 °K to iron's melting point of 1811 °K, ranging between 0.45 - 1.5 J °K-1 g-1. Iron also goes through three phase changes during ...
mass balance around a typical flowsheet for producing one oven dry tonne of pulp. The calculations start at the outlet of the white liquor clarifier by determining the flow of white liquor needed at the digester plus any white liquor required by the pulp mill bleach plant and then calculating the lime required to make that quantity of white liquor.

Thermal Efficiency. An ideal heat engine is an imaginary engine in which energy extracted as heat from the high-temperature reservoir is converted completely to work. But according to the Kelvin-Planck statement, such an engine would violate the second law of thermodynamics, because there must be losses in the conversion process.The net heat added …

A raw mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. It's mainly used in grinding raw materials and end products in cement plant. Raw mill is made up of feeder part,discharging part,rotating part,transmission part (reducer,samll transmission gear,motor,electric control) etc.

Preparation of raw Material. Wood that has been received at a pulp mill can be in different forms. It depends on the pulping process and the origin of the raw material. It may be received as bolts (short logs) of round-wood with the bark still attached, as chips about the size of a half-dollar that may have been produced from sawmill from ...
The efficiency of a boiler is quoted as the % of useful heat available, expressed as a per-centage of the total energy potentially available by burning the fuel. This is expressed on the basis of gross calorific value (GCV). This deals with the complete heat balance and it has two parts:
