Νatural draught flow rate (draft flow) - calculator - fx

The structure which provides ventilation for hot flue gases or smoke from a boiler, stove, furnace or fireplace to the outside atmosphere causes a flow rate. The height that structure (e.g. chimney) influences its ability to transfer flue gases to the external environment via *stack effect*. The higher pressure outside the chimney is the driving force that moves the required combustion air
