Provided is an electric oven including an oven body and an oven door used for opening and closing the oven body. Heating devices are arranged in an inner upper portion and an inner lower portion of the oven body, respectively. A heat-conducting plate is provided on top of the heating devices located on the lower portion. An outer wall of the oven body is detachably sleeved with a silicon rubber case, and concave-convex textures are arranged on the surface of the silicon rubber case. Supporting legs used for supporting the oven body are arranged at the outer bottom of the oven body. Through holes are configured in positions, corresponding to the supporting legs, on the silicon rubber case, and distal ends of the supporting legs, away from the oven body, pass through the silicon rubber case through the through holes.
Provided is a rotary combustion furnace. The furnace comprises: a combustion section, comprising a furnace body, wherein a heat supply port is provided at the top of the furnace body; and a baking section, comprising a baking chamber, wherein a heat collection through hole in butt joint with the heat supply port is provided at the bottom of the baking chamber, and the heat collection through hole and the heat supply port are configured to heat food in the baking chamber. The combustion furnace may be separated from the baking chamber by virtue of providing the combustion section and the baking section which are removably connected, thus decreasing the floor area and making it easy to carry and use in outdoor activities or camping. The heat supply port of the combustion section is in butt joint with the heat collection through hole.
A furnace using biomass pellets as fuel, comprising a housing arranged on a base, wherein the housing is internally provided with a burning chamber, the bottom of which is provided with a burning grate, and the burning chamber is connected with a primary oxygen supply device; the primary oxygen supply device comprises an oxygen supply cylinder that communicates with the outside, and the bottom end of the oxygen supply cylinder is connected with an oxygen supply pipe II configured to blow air over the burning grate, and a plurality of air outlet holes I is defined in the oxygen supply cylinder.
A stove, using biomass pellets as fuels, includes: a stove body that includes a firebox; at least one hopper; and at least one feed tube extending between the at least one hopper and the firebox; and at least one control lever laterally disposed on the at least one feed tube; wherein, fuels within the at least one hopper enter the firebox along the at least one feed tube under gravity when the at least one control lever is in a second position.
A stove using biomass pellets as fuels is disclosed herein, comprising a stove body that comprises a firebox, at least one hopper, and a feed tube, wherein the at least one hopper is connected to the firebox via the feed tube, and fuels contained inside the at least one hopper can enter the firebox along the feed tube under gravity. The stove has a simple structure and removes any mechanically or electrically controlled feeding system by feeding the firebox using gravity of the fuels, therefore lowers the cost.
F24B 13/04 - Arrangements for feeding solid fuel, e.g. hoppers
F23B 50/12 - Combustion apparatus in which the fuel is fed into or through the combustion zone by gravity, e.g. from a fuel storage situated above the combustion zone the fuel being fed to the combustion zone by free fall or by sliding along inclined surfaces, e.g. from a conveyor terminating above the fuel bed
