When you are looking at a system some defined area in which material is entering interacting reacting and perhaps leaving you are interested in more than just th. The fact that the earth can respond to slight changes in the amount of incoming radiation to maintain a fairly stable temperature is a result of earth s energy budget this phenomenon is also closely connected to flows on the earth and the solar energy to the earth. Definition of heat balance i.

A heat balance is another name for an energy balance. For a closed system one that always consists of the same material the first law is q w δe where q is the heat supplied to the system w is the work done on the system and δe is the increase in energy of the material forming the system.
A heat balance sheet is an account of heat supplied and heat utilized in various ways in the system.

Heat balance is an important concept geologically because if the planet is not in a state of relative equilibrium with regard to heat the average temperatures can rise or fall creating either global warming or global cooling. Necessary information concerning the performance of the engine is obtained from the heat balance. Even a slight change in the heat balance of a planet can effect the organisms that inhabit the planet.
The total balance of the blast furnace can give an overall picture of the energy input and output while the multistage balance often two stage balance takes into account the temperature effect on the heat flow according to the second law of thermodynamics. Heat balance definition is the distribution of the heat energy supplied to a thermomechanical system as a steam power plant among the various drains upon it including both useful output and losses. Also the method of determining or the graphical or tabular record of such distribution. To draw a heat balance sheet for the i c.
