A rope is used as a combustible material in a heating system, the rope comprising or consisting of fibrous plant material. Also, a method of operating a heating system comprises feeding a combustible material to a combustion chamber of the heating system, the combustible material being a rope of fibrous plant material.

A heating device, preferably for the combustion of biomass, in particular of pellets of biomass, in one aspect, includes a burner part and a heating part. The burner part includes a combustion chamber; a double-walled, internally hollow combustion-chamber wall, which has an upper opening leading above the combustion zone into the combustion chamber; a flue-gas duct which leads the flue gas downwards along the combustion chamber, wherein the flue-gas duct is followed by a heat-exchanger area including initially, a flat-tube flue-gas heat exchanger, then, a tertiary-air heat exchanger; a flue-gas ventilation stack, a radiant-heat exchanger located above the combustion chamber, a flue-gas flap at the upper end of the flue-gas duct, which, when open, connects the flue-gas duct to the stack. A flat-tube flue-gas heat exchanger of the heating part forms a heat-exchanger circuit with an exhaust-air heat exchanger with the same heat-transfer medium as the flat-tube flue-gas heat exchanger.

An outdoor wood-burning boiler is provided that includes a wood-burning enclosure, a wood support structure, and an air supply system configured for supplying air to wood that is supported by the wood support structure. The air supply system includes conduits for carrying a flow of air. At least one conduit can extend through a sidewall of the enclosure such that an end of the conduit is located outside of the enclosure. The end can include a re-closable closure. The re-closable closure can be configured to be opened from outside of the enclosure and provide access to the interior of the conduit so the conduit can be cleaned. The end and the re-closable closure can instead be located inside the enclosure and accessible through an access panel. An air supply conduit system is also provided that can be installed after-market or as original equipment.

A furnace including a housing and a firebox in the housing having a combustion chamber. The furnace includes a combustion air delivery system for delivering combustion air to the combustion chamber. The combustion air delivery system includes a manifold mounted outside the combustion chamber and extending vertically along the front face of the combustion chamber from a lower end to an upper end. An air blower is mounted on the manifold. The combustion air delivery system includes a primary combustion air passage for delivering air from the air blower to a primary combustion air outlet at the front face of the combustion chamber. The combustion air delivery system includes a secondary combustion air passage for delivering air to a secondary combustion air outlet positioned inside the combustion chamber adjacent the top face of the combustion chamber.

A rotary cascading bed combustion system for converting waste product into energy includes a rotary cascading bed combustor boiler including a rotating cylinder surrounding a combustion chamber; the rotating cylinder being structured and disposed for cascading the fuel to facilitate the mixing of air and solids, wherein the rotational speed of the rotating cylinder is selectively varied based on the amount of fuel, airflow and combustion properties; wherein combusting waste is mixed with sorbents and cycled through a plurality of combustion zones to produce controlled heat for generating steam; wherein the steam is routed to a turbine; and wherein if carbon burnout is not complete it will be recycled back into the combustion chamber.

The invention provides a use of a rope as a combustible material in a heating system, said rope comprising or consisting of fibrous plant material. The invention also provides a method of operating a heating system, comprising feeding a combustible material to a combustion chamber of the heating system, said combustible material being a rope of fibrous plant material.

A combustion apparatus includes a burner having a sheet-metal combustion plate which covers an open surface of a burner body; and a combustion box having a connection flange part to be coupled to a body flange part enclosing the open surface of the burner body, and is equipped with a cooling means for cooling the combustion box, an arrangement is made that overheating of the burner body due to heat transmission from the combustion plate can be prevented, even without enhancing thermal insulation performance of a packing to be interposed between a combustion plate flange part and the body flange part. The connection flange part is kept in direct contact with the combustion plate flange part and, coupled to the body flange part. The packing is provided with: a combustion plate seal part to be pressed under pressure against the combustion plate flange part; and a combustion box seal.
