Chapter 7 The Steel Industry - Princeton University

Since the energy required to melt iron under the most ideal circumstances is about 1 MMBtu/ton, the inherent thermodynamic ad- vantage of making liquid steel from scrap rather than from iron ore is about 6 MMBtu/ton. When process heat losses are included, the advantage falls in the range of 9 to 14 MMBtu/ton.

How to Calculate the Coal Quantity Used in a Power Plant

Heat rate is the heat input required to produce one unit of electricity. (1 kw hr) One Kw is 3600 kJ/hr. If the energy conversion is 100 % efficient then to produce one unit of electricity we require 3600 kJ. After considering the conversion efficiency in a power plant we require an heat input of (3600 / 33.44% ) 10765 kJ/ kw hr. Coal Quantity
