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.

Grill cookboxes including dual-lipped lower rims are disclosed. An example cookbox includes an interior surface, an exterior surface, and a lower rim. The exterior surface is located opposite the interior surface. The lower rim is located along a bottom portion of the cookbox. The lower rim includes an inner lip, an outer lip, and a downwardly facing channel. The inner lip defines an opening formed in the bottom portion of the cookbox. The downwardly facing channel extends between a free end of the inner lip and a free end of the outer lip.

A carbon sequestration system includes a furnace having an oxy-combustion burner, a mill configured to receive a fuel and to provide the fuel to the oxy-combustion burner, a waste heat recovery exchanger configured to receive a flue gas from the furnace, the flue gas ultimately supplied to one or more of an overfire air port of the furnace, the oxy-combustion burner, the mill, and a CO.sub.2 purification unit, the CO.sub.2 purification unit configured to produce a purified CO.sub.2 stream.

The invention relates to a sealing arrangement of a rotary kiln for sealing on a rotary tube, comprising a first and a second seal half (10, 20) and a first and a second traction system (3, 4), wherein the two seal halves (10, 20) exert a tensile force (F) for sealing on an outer periphery of the rotary tube, by means of the two traction systems (3, 4).

A boiler 7 includes: a combustion furnace 100 having a combustion chamber 100F therein; a heat exchanger 140 configured to transfer, to water, thermal energy obtained by burning a solid fuel in the combustion chamber 100F; a belt conveyor 120 including a movable loader 120a, disposed on a bottom of the combustion chamber 100F, and configured to move the solid fuel on the movable loader 120a in the combustion chamber 100F; and a fuel supplier 130 connected to a fuel supply port 111a that communicates an inside and an outside of the combustion furnace 100. The belt conveyor 120 has a starting point below the fuel supply port 111alb . The fuel supplier 130 includes a thickness adjuster 131 that adjusts a thickness of the solid fuel on the movable loader 120a of the belt conveyor 120.

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.
