  • Flue Gas Recirculation: History and Uses - EnviroPower

    Jun 19, 2019 · Boilers run at a range of fuel rates but need to produce steam at a constant temperature. Heat transfer rates are low at lower fuel rates, producing cooler steam from the superheater. Recirculating flue gas effectively counteracts this problem by increasing the flow rate, and thus heat transfer, through the superheater coils.Learn More

  • Exhaust Gas Boilers And Economisers for Marine Machinery

    In the event that the main engine has been operating, with exhaust temperatures above 200 degree C for any length of time, without the circulating pump running, the engine must be slowed down and exhaust temperatures in and out of the exhaust gas boiler to be brought to below 100 Centigrade before starting a circulating pump.Learn More

  • Boiler Flow Rates (Why Mains Pressure Matters) | Combi

    For example, say you have a mains supply flow rate of 9 litres per minute. And you install a boiler with an optimum flow rate of 16 litres per minute. In this case, the mains cannot supply the boiler with enough water to maximise its output. So when replacing a boiler you need to ensure your new boiler has a flow rate that matches your mains Learn More
