A biomass burner includes a lateral shell having an axis of main development and a bottom provided in a lower end of the lateral shell to delimit the lateral shell at the lower part in order to internally define a compartment to contain the biomass. The bottom is able to support the biomass inside the containing compartment and is provided with one or more first holes configured for the introduction of primary air into the containing compartment.

Disclosed is a particle heating landscape furnace, which includes a combustion device. The combustion device includes a vertically arranged cover pipe, a grid and a combustion assembly. The combustion assembly has a feed chamber, a flame outlet and a flame outlet opposite to the flame outlet. A feed chamber is arranged obliquely, the flame outlet and the discharge port are both connected with the feed chamber, and the cover pipe is arranged on a periphery of the flame outlet, the grid is arranged on an outer side of the discharge port.

A device to facilitate and maintain a fire, having a camera assembly with a base, an apex, lateral columns, a first ring, and a second ring; and an air intake channel connected to the camera assembly. The first and second rings are intercepted by the lateral columns to define a plurality of apertures. The camera assembly defines a cavity area. The cutouts are positioned around the base separated a predetermined distance from each other, and extend from the base bottom edge without reaching the base top edge. The main opening extends from the base bottom edge towards the base top edge. The main opening defines a semi-circle. The plurality of apertures defined at the camera assembly and air intake through the air intake channel provide a sufficient amount of oxygen so that a fire is maintained until matter upon the camera assembly is consumed without suffocating and become extinguished.

A pellet stove includes a hopper for storing pellets, a basket for receiving the pellets by gravity, a duct for conveying combustion air to the basket, and a conduit for conducting heated air away from the basket. The position of the basket is adjustable, such as by raising and lowering it, or by rotating it, so as to control the number of pellets in the area of most intense combustion. One or more optional burn plates, positioned below the basket, provide platforms on which pellets falling through the basket can burn down to a smaller size. The pellet stove requires no external source of power. The stove so constructed enables quiet, efficient and clean burning of the pellets.

The present disclosure discloses a secondary combustion with a combustion speed adjustment function, including an outer barrel and an inner barrel; the inner barrel is provided with a combustion cavity; the outer barrel is provided with a first air inlet hole; the inner barrel is provided with a second air inlet hole; a ventilation clearance is reserved between the inner barrel and the outer barrel; a waste tray is arranged in the ventilation clearance; a plurality of third air inlet holes are arranged above the combustion cavity; an adjustment valve is arranged at a lower end of the outer barrel; and supporting legs are arranged on a lower end surface of the outer barrel.

A stove includes a combustion chamber, a fuel grate positioned within the combustion chamber, and a pellet adapter removably positionable on the fuel grate. The fuel grate includes a number of first ventilation holes. The pellet adapter includes a number of second ventilation holes sized and shaped to prevent passage of a fuel pellet. The pellet adapter also includes a raised outer rim and a central protuberance with a height greater than the height of the raised outer rim.
