Abstract
A burner for the firing of ceramic articles which can be installed in an industrial kiln can include a firing chamber; the burner further including a mixing body; a spark device; a flame detection device; a first tubular discharge element configured to be flown through by a fluid flowing out of the mixing body and provided with a first end and with a second end opposite the first end; wherein the mixing body comprises both a partitioning system of the fuel, configured to divide the fuel in a plurality of first portions, and an oxidizer partitioning system, configured to divide the oxidizer into a plurality of second portions, which are conveyed so as be mixed in at least two different stages with the first portions.
Claims18
A burner for the firing of ceramic articles (T), which can be installed in an industrial kiln comprising a firing chamber;
- the burner comprising:
- a mixing body comprising, in turn, at least one duct to feed a fuel (FL) provided with a percentage of hydrogen and at least one duct to feed an oxidizer (OX);
- a spark device to start a combustion;
- a flame detection device;
- a first tubular discharge element, which is configured to be flown through by a fluid (F) flowing out of the mixing body and is provided with a first end, into which at least part of the mixing body is inserted, and a second end, which is opposite the first end;
- wherein:
- the mixing body comprises both:
- (i) a fuel partitioning system (FPS) for the fuel (FL), which is configured to divide the fuel (FL) into a plurality of first portions (FL′, FL″, FL′″), and (ii) an oxidizer partitioning system (OPS) for the oxidizer (OX), which is configured to divide the oxidizer (OX) into a plurality of second portions (OX′, OX″, OX′″), which are conveyed so as be mixed in at least two different stages with the first portions.
