摘要

Changes in a heating Boiler gas Burner splante without and with control of partial load.Namely: to Seal the combustion chamber (3) open to the elements of a Heat exchanger (1) in its walls and the air valve (7) to the edges (8) against False entry of air into the combustion chamber (1); present the Venturi Tube (5) Cross Section That limits the amount of combustion air to a fixed part of the amount of Air neededAria in the full load operation; providing the air valve (7) with an Opening (10) calibrated for the entry of Air Flow differential required.
