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:
Aug 26, 2021· Successes in condensation-type solvent-recovery systems are tied to heat transfer, so it is important to audit the system's energy balance periodically to validate its effectiveness. Even when a system is operating at design conditions, downstream process samples may report higher concentrations than those predicted by vapor-liquid ...
Use for energy balances. Sankey diagrams are ideal for visually representing energy balances. This is because an energy balance represents the contribution and flow of various energy commodities (fuels, heat and electricity, i.e. energy carriers in a marketable form) into the different sectors of the economy (e.g. supply, transformation and consumption) in energy units.
