A vented fire tarp is provided that includes a base portion and a plurality of vents formed in the base portion, wherein each vent allows for air, smoke, and carbon dioxide to pass through the vent from one side of the base portion to the other. The vented fire tarp also includes securing devices to couple the base portion to a ground surface over a fire. In use, the vented fire tarp covers a fire and controls a burn rate of wood of the fire in response to controlling airflow through the plurality of vents of the vented fire tarp.

System for cleaning the burner and confining fuel in solid-fuel boilers of the type that consist of one plate, one supply device, at least one ash discharging device. The plate is mobile and has means to rotate with respect to the supply device and/or to each ash discharging device; each ash discharging device is fixed and has at least one blade with means to guide it at will on the plate occupying at least part of its perimeter. The blades of each ash discharging device are increased in height and occupy the entire perimeter of the plate, all of them delimiting, in conjunction with the plate and in an initial position where they act as side slats, a perimetrally closed container to confine a larger quantity of solid fuel on the plate without varying its size.

A biomass burner includes a hopper, a ventilating chamber, a U-shaped fire box, a feeding cylinder including an output end, an auger, a feeding motor including a driving wheel, an ignition device, an ignition motor, a ventilation plate, a first poking device, a second poking device, a first poking motor configured to drive the first poking device, a second poking motor configured to drive the second poking device, a first fixed plate, and a second fixed plate. The hopper is disposed below the feeding cylinder. The feeding cylinder is disposed through the ventilating chamber and the output end of the feeding cylinder extends into the U-shaped fire box. The auger is disposed in the feeding cylinder and is driven by the feeding motor; one end of the auger is provided with a driven gear, and the driven gear is meshed with the driving wheel of the feeding motor.

This solid fuel burner is provided with: a venturi tube in which a channel for mixed fluid in a fuel nozzle narrows toward the center in the channel cross section; a fuel concentrator that imparts, to the mixed fluid, a velocity component away from the center of the fuel nozzle; and a channel separation member that separates the channel of the fuel nozzle into an internal side and an external side; wherein the channel separation member is shaped in such a way that the cross sectional area of an external channel is larger at the downstream end than at the upstream end, and the upstream end of the fuel concentrator is located between the upstream end and the downstream end of an expanded portion of the venturi tube. This solid fuel burner prevents solid fuel particles, which is ground biomass fuel, from adhering and depositing inside the nozzle.

A heating apparatus for supplying heated air to a dryer for grain or other particulate materials. The apparatus features a biomass furnace with a burn chamber for combustible biomass material, a chimney having a lower end in fluid communication with the burn chamber interior, and air ducting that has a fresh air inlet, an output end connected or connectable to the dryer, and is in in fluid communication with the chimney to enable redirection of said heated exhaust air from the chimney to the dryer via the air ducting. An airflow control system is configured to both control airflow to the dryer through the air ducting, and control a temperature of said airflow by varying a ratio between the fresh ambient air and the heated exhaust air.

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.

An apparatus for cooking, a cooking appliance monitoring system, and a method of monitoring a cooking appliance are provided. The monitoring system collects and processes signals from sensors linked to the cooking appliance. Further, the monitoring system determines attributes of parameters associated with the cooking appliance and stores the attributes in a cloud-based system and stores the metadata about the attributes in a blockchain.

A heating apparatus can include a fire cage defining a cage space containing heated fuel. The heating apparatus can also include a container configured to be supported by the fire cage at a container position, wherein the container is above at least a portion of the cage space. The container can be designed to hold burning fuel above the heated fuel. Also, a heating apparatus can be arranged to form a food grill, and the heating apparatus can be rearranged to form a fire cage configuration. A thermal store can be placed in a heat collecting position on a side of the fire cage in a first location to heat the thermal store. The thermal store can be moved away from the fire cage and can be positioned in a second location away from the fire cage to emit thermal energy to heat air around the second location.

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.
