摘要

The unit has a combustion chamber (7), a following flame tube, a heat exchanger, means for fuel and combustion air feed, an ignition device a device for conducting away heat transmission means and exhaust gas, together with a ring chamber enclosing the combustion chamber (7) with a floor (7a) and air through passage apertures (12) in the peripheral wall. The floor of the combustion chamber has a central downstream open insert (15) which is pot-shaped and of a material capable of suction and heat-resistant, which has air through passage apertures (14) in the peripheral wall. ADVANTAGE - It burns well even in the lower part load range and remains within acceptable limits even at full load.
