The two or more gas hookups are connected to the table so as to be portable therewith, the two or more regulator and flow meter pairs are connected to on the table so as to be portable together therewith, the two or more control valves are connected to the table so as to be portable therewith, and the two burner heads are likewise connected to the table so as to be portable together therewith. At least one of the two burner heads is connected to the table via a moveable mount allowing the distance between the burner faces to be adjusted.
Abstract:
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.
Abstract:
A valve (1) for supplying fuel gas to a gas appliance comprises a valve housing (2) having a valve chamber (3) extending therethrough. Fuel gas is supplied through an inlet port (5) to the valve chamber (3) and form main and secondary outlet ports (6, 7) to a burner and a pilot light jet, respectively, of the gas appliance. A primary valving member (35) and a secondary valving member (36) co-operate with a primary valve seat (15) and a secondary valve seat (20), respectively, for isolating the main and secondary outlet ports (6, 7) from the inlet port (5). A main carrier member (30) carries the primary valving member (35) and is magnetically coupled to a first secondary carrier member (31) which is driven by a stepper motor (38). A second secondary carrier member (32) is magnetically coupled to the main carrier member (30) for carrying the secondary valving member (36). Electromagnetic coils (60, 61) magnetically couple the first and second secondary carrier members (31, 32) to the main carrier (30) so that the drive motor (38) can operate the main carrier (30) and in turn the primary and secondary valving members (35, 36) for opening and closing primary and secondary communicating passageways (19, 25) through the primary and secondary valve seats (15, 20).
