Portable burning stove providing warm air
11143408 · 2021-10-12 ·

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.

Hybrid boiler-dryer and method

A method for reducing the emission of contaminants by a furnace is provided. The method includes forming a bed from a stream of fuel within the furnace; fluidizing the bed with flue gas from the furnace; and heating the fuel within the bed so as to generate char, ash and contaminants. The method further includes capturing the contaminants via the ash.

A smoker configured to infuse smoke into flavor and/or taste of a beverage or food includes a body member having a through bore extending from a first end of the body member to an opposite second end of the body member in a first direction and an insert configured to be received in the through bore at the first end and retained by the through bore at a position between the first end and the second end. The through bore and the insert are configured to define a chamber for receiving a combustible material between the insert and the first end, the through bore is configured to permit a flow of smoke from the combustible material out the through bore at the second end of the body member, and the second end of the body member is configured to rest on a rim of a container to block the flow of air from the container where a surface of the second end of the body member contacts the rim.

Combustion by controlled ionisation
11105503 · 2021-08-31 ·

This invention is intended to produce more energy during the combustion of fuels (solid, liquid or gas). This is achieved by separating the electrons and the cations which are produced at the very beginning of the phenomenon of combustion. This way of making conducts to more violent shocks between the cations (C+++; H+) and the anions (O−−); thus more energy.

COMBUSTION SYSTEM COMPRISING AN ANNULAR SHROUD BURNER

The present disclosure is directed to systems and methods for high flame temperature oxy-combustion that enables the capture of CO.sub.2 cost effectively. One part of the presently disclosed subject matter comprises an annular shroud burner which utilizes a supply of undiluted oxygen and minimal flue gas recycle to generate a high flame temperature to maximize efficiency. The annular shroud burner may deliver oxygen into a combustion zone where mixing of the oxygen and a stream of fuel occurs. Flue gas recycled from the exit of the combustion system serves the dual purpose of conveying the coal into the reaction zone, as well as providing local cooling and protection from high incident heat fluxes through the novel shroud cooling design. The annular shroud burner may be configured to produce an axial jet flame that controls the rate of mixing of oxygen and fuel, thereby extending the heat release. Oxygen and coal may be mixed in a ratio such that peak flame temperatures exceed 4,500° F. (2,482° C.) while the flow of recycled flue gas is regulated to control flame temperature and protect burner components and near-burner surfaces.

ORGANIC MATTER DEGRADATION DEVICE
20210164654 · 2021-06-03 ·

An organic matter degradation device has a furnace and a gas supply device. The furnace has a furnace chamber. The gas supply device has a gas supply tube and a negative ion generating device. First branch tubes are disposed on the gas supply tube axially, and second branch tubes are disposed on the first branch tube. A first pipeline of the second branch tube is disposed horizontally, the first pipeline is communicative to the first branch tube via the second pipeline, and the negative ion generating device is installed on the first pipeline. The negative ions generated by the negative ion generating device can pass the first pipeline and directly enter the furnace chamber, which decreases the resisting force applied to the negative ions, and increases the negative ion flow kinetic energy.

Infrasound generator for enhancing the combustion of solid fuels
10974279 · 2021-04-13 · ·

The invention refers to an infrasound generator for enhancing the combustion of solid fuels burning in a combustion chamber. The infrasound is generated by one or more set(-s) of each two vibrating plates, vibrating in the same direction with the same displacement amplitude but in antiphase. The infrasound generator does not cause vibrations and is not sensitive to ash and heat from the combustion.

The invention comprises: a) first comburent supplying means (18) connected to the lower part of the oxidation chamber, for introducing pressurized oxygenated gas in the oxidation chamber at a speed that comprises a tangential component; b) a particle recirculation system, which comprises: a particle separator (24) on the upper part of the oxidation chamber for trapping hot particles of ash and unburned material, and a transportation system (25) for transferring trapped particles from the particle separator (24) to the base of the oxidation chamber; and c) a gas recirculation system comprising: a sucker (26) for suctioning combustion gases from the upper part of the oxidation chamber, and pipes (27) for transferring the suctioned gases to the base of the oxidation chamber. It provides an optimized thermal transfer that reduces the emission of pollutants in waste recovery.

Forced primary and forced secondary air biomass internal combustion top-lid updraft cook stove
20210063019 · 2021-03-04 ·

The invention is a novel Top-Lit-Updraft cook stove with internal forced primary and secondary air, designed to burn biomass. The cook stove is specifically designed to cleanly burn biomass. The stoves design innovations include a cylinder-within-cylinder design to provide heated, forced secondary to the burner area right below the burner. The burner design addresses limitations in previous cookstove burner design by implementing a bluff body design to direct syngas to the secondary air jets, improving mixing and combustion of volatile gases.
