15 Ways to Increase Boiler Efficiency in Your Facility

Jul 30, 2020 · Over time, soot may build up on the fireside of the boiler tubes, especially with older equipment. This layer of soot acts as an insulator, bringing down the heat transfer rate and increasing fuel use. Because of the lower heat transfer rate, the hot gases pass through without transferring the heat to the water, increasing your stack temperature.

Heat transfer - Wikipedia

Heat is defined in physics as the transfer of thermal energy across a well-defined boundary around a thermodynamic system.The thermodynamic free energy is the amount of work that a thermodynamic system can perform. Enthalpy is a thermodynamic potential, designated by the letter "H", that is the sum of the internal energy of the system (U) plus the product of pressure (P) and volume (V).
