4.2 Operating principle
MEGAPREX N boilers are fitted with a closed cylindrical furnace, in which the flame produced by the burner is reversed peripherally toward the
front. From there, the burned gas enters the fire tubes. At the outlet, the gas is collected in the smokebox, and is then sent to the chimney. The
combustion chamber is always pressurized during burner operation. For the pressure values, see Table 1, in the column Flue gas side pressure
drop. The flue and flue stack fitting must be made in accordance with current standards and legislation, using rigid pipes that are resistant to
high temperatures, condensate, and mechanical stress, and are airtight.
