PREXTHERM RSH N
4.2 Operating principle
PREXTHERM RSH 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 smoke box, 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.
