Furnace heat regulation system - transfers heat from combustion gas to fresh ambient air delivered to furnace

摘要

The furnace heat regulation system exchanges heat between the air charged with combustion gas and the fresh ambient air, which is then delivered, in whole or in part, inside the furnace. There can be fan positioned at the combustion gas outlet and working with a set of shutters mounted in a distribution nozzle. This delivers hot air to a drier supply pipe and to a chimney, and also the furnace via a recycling conduit. The fresh air intake can be between the combustion gas outlet and the fan, and there can be two recycling conduits at the sides, connecting the hot air inlet conduits to the distribution nozzle.
