Heat and mass balance is a document produced by process design engineers while designing a process plant. Sometimes heat and mass balance is not a separate document but appears alongside the Process Flow Diagram (PFD). A heat and mass balance sheet represents every process stream on the corresponding PFD in terms of the process conditions.

Most heat rate deviations are often small in relation to the overall heat rate. For instance, a 70 Btu/kWh deviation is only 1% of a 7,000 Btu/kWh heat rate that is normal for a combined cycle plant. This does not mean much to most people; however, if we calculate the fuel cost associated with the heat rate deviation, this puts in perspective what this is really costing the plant.

Earth''s heat balance is and extremely important factor in what makes the Earth livable. 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 phenomenon is also closely connected to flows on the Earth, and the Solar energy to the Earth.

WhatsApp A mass balance, also called a material balance, is an application of conservation of mass to the analysis of physical systems. By accounting for material entering and leaving a system, mass flows can be identified which might have been unknown, or difficult to measure without this technique. The exact conservation law used in the analysis of the system depends on the context of the problem
WhatsApp There is wide variation in energy balance across refinery configurations. Refineries such as those in West Iowa, near corn supplies, livestock operations, transport infrastructure, and final markets have the best energy balance. There is a significant potential for a 30fold improvement in energy balance by using biomass (stover)powered
WhatsApp Earth''s energy budget accounts for the balance between the energy that Earth receives from the Sun, and the energy the Earth radiates back into outer space after having been distributed throughout the five components of Earth''s climate system and having thus powered Earth''s socalled heat engine. This system is made up of Earth''s water, ice, atmosphere, rocky crust, and all living things.

Heat balance. An application of the first law of thermodynamics to a process in which any work terms are negligible. 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.
