Combustion of hot gases of low calorific power

A combustion chamber for the complete combustion of hot gases of low calorific value, comprising:

• a. a chamber having a vertical wall, a base and top, said vertical wall disposed between said base and top,
• b. a chimney connected to the top of the wall for the discharge of combustion productions from the chamber,
• c. a base plate associated with the base of said chamber,
• d. at least one burner upwardly directed associated with the base plate and having a nozzle arranged to supply gas at a pressure close to atmospheric pressure and means for force supplying said primary air,
• e. said base plate including for each of said at least one burner, peripheral oblique convergent nozzles directed to a point situated above the burner and comprising means for force supplying said secondary air,
• f. distribution means for distribution of combustion air flow in two parts, one part directed to the burner and the other part to the peripheral nozzles,
• g. first regulating means operable to control the flow of air for combustion depending on the temperature in the vicinity of the top of the chamber, and
• second regulating means operable to control the distribution of the flow of primary air and the flow of secondary air depending on the flame temperature.
