Stationary hot air generator MARSILI

biomassindustrial

The MARSILI hot air generation system is designed and built to produce hot air for use in various drying processes—both for food products (using a heat exchanger) and for agricultural products intended for animal feed, olive pomace, sawdust, etc. There is a basic configuration of the system related to hot air generation, which includes the fuel feeder and doser, the heat generator, the flue gas cleaning and shaping chamber. Feeder The feeder consists of a motorized hopper equipped with level sensors, where the fuel is stored. A spring extractor rotates at the base of the hopper, pushing the material towards the feed opening connected to the burner auger. Burner Auger It is made up of two superimposed augers: The upper auger receives the material from the feeder above and doses it to the lower auger, The lower auger then transports the fuel to the crucible located inside the combustion chamber. The two augers are driven by a single gear motor connected via a chain and sprocket system. This system is designed so that the dosing rate of the upper auger is lower than that of the lower auger, in order to prevent clogging and to avoid potential fire hazards from residual material in the feeder when the generator is turned off.
