HIGH-PERFORMANCE HOT-AIR GENERATOR PROVIDED WITH EFFICIENT BIO-MASS BURNER

摘要

The invention relates to a high-performance hot air generator provided with an efficient bio-mass burner, meant to heat, at low costs, large spaces, such as workshops, garages, industrial halls, shops, green houses, solaria, auditoriums, gymnasiums, office and dwelling buildings. According to the invention, the generator consists of a primary combustion chamber (2) or fireplace, a horizontal main-combustion chamber (9) and a vertical total-combustion chamber (12), the primary combustion chamber (2) being made of a steel tube and provided in the upper side with a primary air inlet (3) and with an adjusting valve (4), and in the lower side with a slot (6) through which the flame resulting from the primary combustion passes downwardly, a fuel supply door (5) is mounted in the front side, and, in the rear side, a valve (1) is placed to be opened when initiating the combustion, in order to prevent the smoke exit into the enclosure, the main combustion chamber (9) is made of a steel pipe and it is provided in the front side with a secondary air inlet (7) and an adjusting valve (8), in the upper side it communicating with the slot (6) of the primary combustion chamber, and in the rear side with a vertical combustion chamber (12) made of refractory materials, a heat exchanger (13) is made of some concentric steel tubes and, is provided in the upper side with a valve (16) which is opened when starting the fire and closed during operation, a wall (14) of the generator being also made of a steel tube, the hot-air generator being also provided with an inlet connection (10) and a fan (11) for entraining the heated air, with a heated air discharge connection (15) and a connection (17) for the smoke stack.
