Method for introduction of a fuel mixture, including methane and an aggregate of air and coal dust, into a combustion chamber and/or into a kiln through a series of injectors (10) including at least one pair of ducts, a working end (13) situated inside said chamber (F) includes the following working steps: A: collecting coal dust from a storeroom (1) and conveying the collected dust to the inlet (I) of a first forced conveyance conveying path (20), communicating with the first ducts (12) of the injectors (10), by first branching members (21) having first valve means (22); B: aspirating air from the surrounding environment and conveying it to the inlet (I) of the first forced conveyance conveying path (20) to form an aggregate formed by the coal dust and the aspirated air; C: conveying the aggregate -along the first forced conveyance conveying path (20) and conveying methane, taken from the relative source, along a second forced conveyance conveying path (40), communicating with the second ducts (11) of the injectors (10) by second branching members (41) having second valve means (42); D: contemporary introduction of the aggregate into the injectors (10), through the first branching members (21) by opening the first valve means (22), to make it pass through the first ducts (12), and of methane, through the second branching members (41) by opening the second valve means (42), to make it pass through the second ducts (11), so as to convey the two components toward the working ends (13) in order to mix them, due to their passage at the working ends (13) and to introduce, into the chamber (F), with relative combustion, a fuel mixture including, at the same time, methane and an aggregate of air and coal dust. |
