Cast-iron sectional boiler i.e. calorific value boiler, has boiler members forming combustion chamber with surrounding gas flues, where water flows into inner water chamber by water base between inner and outer water chambers
摘要
<p>The boiler has circular boiler members (1) forming a combustion chamber with surrounding heating gas flues. An inflow opening (11) is formed on each boiler member in a lower region of the heating gas flues, where the inflow opening is provided for heating gas in a modular-like calorific value-heat exchanger (9) that is arranged in a retainer. The return water partially flows into an inner water chamber (4) by a water base (6) that is arranged between the inner water chamber and an outer water chamber (5) in a lower region of one of the boiler members.</p>
