Burner and applications thereof

A burner comprising a housing, a fan, a burning head and an ignition mechanism, wherein:

• the housing comprises an air inlet, the air inlet and an input end of the burning head form a pressure equalizing cavity;
• the fan blows a mixed gas comprising a fuel gas and air through the burning head to uniformly mix the mixed gas;
• the ignition mechanism is arranged at an output end of the burning head and is configured to ignite the mixed gas;
• the burning head comprises a main frame and at least one stable burning isolation strip;
• an interior of the main frame is divided into at least two ventilation areas by the at least one stable burning isolation strip in a gas channel direction;
• a plurality of separation mechanisms are arranged in each ventilation area and divide each ventilation area into a plurality of through holes;
• and
• the plurality of through holes are configured to allow the mixed gas to pass through;
• wherein:
• one or more of the at least one stable burning isolation strip is attached to a surface of the main frame, or penetrates the main frame in a thickness direction, or extends into the main frame by a preset length and one or more of the at least two ventilation areas are embedded in the main frame, or
• one or more of the at least two ventilation areas and one or more of the at least one stable burning isolation strip are integrally fixed on the main frame, or
• one or more of the at least two ventilation areas and one or more the at least one stable burning isolation strip form an integral structure;
• each through hole has a cross-sectional area Shole satisfying 0.1 mm2≤Shole≤9 mm2;
• each ventilation area comprises a plurality of through holes and has a cross-sectional area Sn satisfying 30 mm2≤Sn≤22500 mm2;
• a thickness dhole of each separation mechanism satisfies 0.03 mm≤dhole≤3 mm;
• the main frame has a wall thickness douter satisfying 0.03 mm≤douter≤50 mm;
• the ventilation areas have a height h satisfying 4 mm≤h≤1000 mm;
• each stable burning isolation strip has a width D1 equal to a total length of three to ten through holes, and satisfying 2 mm≤D1≤50 mm;
• and
• the stable burning isolation strip is continuous or discontinuous, and a discontinuous section has a width D2 that equals a total length of one or two through holes.
