摘要： An arrangement for adjusting the ratio between supplied amounts of fuel (PA) and air (I) in a burner, which is intended for a gaseous and/or liquid fuel is disclosed. The burner comprises a fuel and air mixing zone, a fuel supply conduit adapted to supply the mixing zone with a given inlet flow of fuel, a combustion air supply means adapted to supply the mixing zone with a given inlet flow of combustion air, and burner automation. The burner automation contains measuring instruments. The burner has its mixing zone accompanied by a combustion chamber which is in communication with a flue gas conduit. The combustion chamber or flue gas conduit has at least one catalytic zone. In the arrangement, the measuring instruments include at least one sensor, such as a lambda sensor, measuring the amount of residual oxygen in flue gases (flue gas oxidation/reduction potential). In the arrangement adjustment for an inlet flow (QI, QItot) of combustion air generated by the combustion air (I) supply means (determined as a volume flow per unit time), as well as the adjustment for an inlet flow (QPA, QPAtot) of fuel arriving in the mixing zone by way of the fuel supply conduit (determined as a volume flow per unit time), by means of burner automation, is based on the amount of residual oxygen measured from flue gases (S) with the measuring instrument, by way of which the burner automation adjusts the relative ratio between said inlet flow (QI, QItot) of combustion air as well as the inlet flow (QPA, QPAtot) of fuel in such a way that the amount of residual oxygen is within the range of 0.05-0.5% in flue gases prior to the catalytic zone.

摘要： The invention relates to a burner installable to a boiler for burning a premixed air-fuel mixture, said burner comprising a frame member provided with an elongated combustion head protruding from the frame member and having what in a view from the frame member is its distal end provided with a tip plate. In said burner between a side edge of the tip plate and the plane of the tip plate is an oblique angle of incidence for directing a gas delivered forward of the tip plate away from the longitudinal center axis of the combustion head, the combustion head has its tip plate provided with a plurality of air openings extending through the tip plate and it is for cooling the tip plate that the inner tube is additionally provided with a supply of combustion air for conveying the combustion air through the tip plate's air openings.

摘要： A burner (1) installable to a furnace (9) for burning an air-fuel mixture and for generating a flame in the furnace (9), said burner (1) comprising a frame member (6) provided with an elongated combustion head (2) protruding from said frame member (6) and being adaptable inside the furnace (9), what in a view from the burner's (1) frame member (6) is a distal end (2a) of said combustion head (2) being adaptable to generate both a main flame (B) and a primary flame (E), said combustion head (2) comprising an outer, larger diameter channel (3) for a mixture (80) of combustion air and fuel, as well as a smaller diameter, inner channel (4), surrounded by said outer channel (3), for primary air (60) as well as for primary gas (70), whereby

the inner channel (4) extends from the burner's frame member (6) to the distal end (2a) and comprises an inner tube (4, 41) for primary gas (70) and an outer tube (4; 42) surrounding said inner tube (4; 41), wherein a flow space (4; 43) for primary air (60) is provided between the outer side of the jacket (41a) of said inner tube and the inner side of the jacket of the outer tube, and which combustion head's (2) outer channel (3) extends from the burner's frame member (6) to the combustion head's distal end (2a) and can be provided with a supply of premixed air-fuel mixture (80) from the burner's frame member (6), or from that section of the combustion head (2) which is associated with the frame member and located, in the flowing direction of the premixed air-fuel mixture (80), upstream of a combustion chamber (90), for generating the main flame B).

In said burner the space delimited by the outer wall (31) of the outer channel (3) and the jacket of the outer tube (42) of the inner channel (4) is constructed as a discharge channel (10) extending from the frame member (6) to the distal end (2a) of the combustion head (2), whereby the discharge end (10a) of said discharge channel is veered away from the longitudinal center line (P) of the combustion head (2) so that the center line (10A) of said discharge end (10a), or an extension thereof, forms an inclined angle of incidence (t) with the combustion head's (2) longitudinal center line (P), said angle of incidence (t) being 90-140 degrees as said discharge end (10a) of the discharge channel (10) is viewed from the direction of the burner's (1) frame member (6),

a flow controller (7) is provided in the flow space (4; 43) for primary air, at the distal end (2a) of the combustion head (2), for directing the flow of primary air (60) in the flow space (43) so that the primary air (60) flows from the flow controller (7) towards the mouth (43a) of the flow space (43), in the vicinity of the jacket (42a) of the outer tube (4; 42) of the inner channel (4),
a plurality of nozzles (8) is provided in the inner tube (4; 41) of the inner channel (4), at the distal end (41a) of said inner tube (4) in the flowing direction of the primary gas (70), for directing the primary gas (70) into the flow space (4; 43), either upstream or downstream of the flow controller (7) in the flowing direction of the primary air (60).
