Furnace


Furnace heating systems heat air in a combustion chamber. The energy performance of a furnace heating system is influenced by a number of factors such as the type of fuel, the furnace capacity and seasonal efficiency. Other factors include the size and the type of the heating load (i.e. space and/or process heating, single or multiple zones, single or multiple buildings). Refer to the Fuel-Fired Furnace Schematic and the Furnace Losses Diagram for more information.

Software & Data
The RETScreen Software Furnace Model can be used worldwide to evaluate the energy production and savings, costs, emission reductions, financial viability and risk for furnace projects, ranging in size from high efficiency condensing furnaces for space heating in residential, commercial and institutional buildings, to industrial process furnaces and ovens in foundries, brick and ceramic manufacturing plants and chemical plants. The software (available in multiple languages) also includes product, project and climate databases, and a detailed user manual.
