A heating device having a burn chamber that includes at least one opening, a conduction chamber adjacent to the burn chamber and including at least one aperture, a heat manifold including a first port and a second port, and at least one source vent extending between and coupling the first port of the heat manifold to the at least one opening of the burn chamber, and at least one exhaust vent, protruding from a surface of the heat manifold and extending between and coupling the second port of the heat manifold to the at least one aperture of the conduction chamber.

Disclosed herein is a self-assembly brazier. The self-assembly brazier includes: a pair of floor plates arranged bilaterally symmetrical to face each other; a pair of side wall modules having a plurality of side panels disposed to be rotatable, being combined with each other to face each other symmetrically so that a combustion space is formed, and being arranged on upper surfaces of the floor plates to be erected; and a pair of fuel loading parts seated inside lower portions of the side wall modules so that fuel is loaded on the upper surfaces of the fuel loading parts.

The present disclosure describes a chimney vent cap for controlling the flow of exhaust gases exiting a vent stack or chimney of a grill, cooker, smoker, or other device. The chimney vent cap is adapted to receive and reside about the vent stack or chimney and is configurable in multiple configurations using single plane movement and absent insertion of a user's hand into the exhaust gases, with each configuration corresponding to a particular flow rate of exhaust gases through the chimney vent cap and, hence, through the vent stack or chimney. The chimney vent cap is adapted to retain such configuration absent user intervention during movement of the vent stack or chimney caused by opening and closing of the lid or top of such grill, cooker, smoker, or other device, such that the flow rate of exhaust gases after such movement is substantially the same as prior to such movement.

A burner for burning fuels and modular heat utilizing appliances therefor. The burner includes a fuel holder, an outer wall surrounding the fuel holder and defining a combustion chamber, and optionally, a second wall surrounding the outer wall. Air is inducted from an inlet which may be an ash pan pivotally coupled to the outer wall at the bottom to open the combustion chamber. Supplementary combustion air is conducted to just above the fuel holder by the outer wall. Additional supplementary combustion air is conducted to just above the fuel holder by the second wall. The burner may include a pivotally mounted cooking grate and a pivotally mounted solid cover for closing the combustion chamber, and supporting legs. Modules individually yet replaceably attachable to the burner include a closed or open cooker, a smoker, a space heater, and a pyrolyzer.

A portable biomass stove includes a tubular seat unit and an insulation unit. The tubular seat unit includes an inner tubular seat and an outer tubular seat. The outer tubular seat surrounds the inner tubular seat, cooperates with the inner tubular seat to define an internal space therebetween, and is formed with an air inlet located under the tubular body. A top end portion of the outer tubular seat is connected to a top end portion of the tubular body in a sealing contact manner. The insulation unit is disposed in one of the internal space and an ambient space outside the outer tubular seat so as to prevent dissipation of heat out of the outer tubular seat.

In one aspect, a stove can include a first cover including a cavity, and a second cover including a cavity. The stove can include a main portion including a first end portion and a second end portion. The first end portion can define a first opening and the second end portion define a second opening. In a stowed configuration, the first end portion of the main portion can be disposed in the cavity of the first cover and the second end portion of the main portion can be disposed in the cavity of the second cover. In a deployed configuration, the second cover can be arranged so that the cavity of the second cover is facing in a downward direction away from the main portion.

A system and method of tracking and classifying an athlete's stick techniques used during a sporting event are disclosed, which includes measuring detailed motions and position of at least one stick object being used in sports, producing relevant stick technique patterns and classifying those patterns in a relevant manner. Classified stick pattern data is used to improve the accuracy and clarity of sporting event metrics, the ability to quantify athlete's skill and the ability to develop athletes based on their game situation techniques. The method used allows for accurate, near real-time discovery of stick patterns during live sporting events without altering or impacting the game or an athlete's ability to perform.

A burning stove includes a stove body, a front seat, a door, a rear seat, a top cover, and a baffle. The baffle divides the stove body into an air inlet chamber and a combustion chamber. The door is provided with first air inlet holes and second air inlet holes. The baffle is provided with first air holes. The baffle is provided with an air guide port and an air guide face. First partial air flows backward in the air inlet chamber, flows through the air guide port and the air guide face, and flows upward into the combustion chamber, and second partial air in the air inlet chamber flows through the first air holes into the combustion chamber. The first partial air and the second partial air form a vortex air flow in the combustion chamber.
