Small stove, stove core and shape of briquette assorted with smokeless combustion of combustible solids/semisolids

A novel stove assorted with a briquette stack for smokeless combustion of combustible solids/semisolids applied prominently to the field of non-forced combustion and usually to medium/small stoves, using a thermally insulating/refractory stove core and a flame concentrator, and a shape of briquette capable of ensuring sufficient ventilation quantity to match the briquette stack for smokeless, efficient and clean combustion, the stove core and the shape of briquette, characterized in that, as compared with existing stoves, stove cores and shapes of briquette with good thermal resistant and poor thermal insulation for anthracite briquettes and compared with known similar stoves, stove cores and shapes of briquette for “beehive briquette for upper ignition”:

• I, a section A stove core inner ring (2) or an integrated stove core, the flame concentrator (6) or the whole core are made of high-whiteness aluminum silicate fibers with thermal insulation/resistance effects selected as main materials, a section A stove core outer ring (17) is made of cheaper foam glass, foam ceramic or calcium silicate, and the two are bonded and combined to form a section A stove core;
• II, a recess is pressed on the top of a small-diameter cylindrical underlying briquette (9) which has difficulties in aligning vent holes, such that hole alignment is simple, convenient and quick;
• III, an overall cross-sectional area of the vent holes of the briquette stack and an area of an air inlet and slag outlet opening (5) are expanded by more than 30% compared with that of existing anthracite briquettes with the same diameter, and the air vents are properly arranged to ensure a more reasonable air distribution so as to meet the requirement of sufficient combustion of a pyrophoric briquette (10) having more than 40% of volatile component;
• and IV, the height required by a large combustion chamber (7) is obtained by properly adjusting the height of the pyrophoric briquette (10).
