10results about "Liquid fuel burner" patented technology

The present invention relates to particular combustors, and e.g., to a combustor comprising a central primary fuel lance, a pilot fuel conduit, a primary oxidant conduit, a secondary oxidant conduit, and optionally a secondary fuel conduit, which are arranged in a particular and advantageous manner so as to surround each other at least in their downstream sections. The invention also relates to a furnace comprising the burner and a method of operating the burner. The burner according to the invention provides, in particular, a particularly advantageous way that comprises a pilot burner as part of the main burner in order to ignite a liquid fuel flame in a cold furnace. If desired, the pilot flame may help extend the flammability limit or operating range of the liquid fuel burner.

A burner includes an atomizing chamber, a flame tube in front of the atomizing chamber adapted to direct combusting fuel introduced by the atomizing chamber along an interior of the flame tube, and a controller. The controller is programmed to independently control rate of fuel flow to the atomizing chamber, rate of atomizing air flow to the atomizing chamber, and rate of combustion air to the flame tub. The controller is also programmed to perform operations including regulating, based on output of a gas sensor, at least the rate of combustion air to the flame tube to substantially maintain a first predetermined amount of excess air in the flame tube.

A burner comprising least one first passage and at least one second passage are formed in the burner, the at least one first passage and the at least one second passage are arranged such that a first fluid from an outlet of the at least one first passage and a second fluid from an outlet of the at least one second passage are mixed with each other, and the at least one first passage is configured to cause the first fluid to produce a rotational flow in a first rotation direction, and / or, the at least one second passage is configured to cause the second fluid to produce a rotational flow in a second rotation direction.

The present invention relates to a burner, in which at least one first passage (21) and at least one second passage (31) are formed, said at least one first passage (21) and at least one second passage (31) being arranged such that a first fluid from an outlet (23) of the at least one first passage (21) and a second fluid from an outlet (33) of the at least one second passage (31) mix with each other, and the at least one first passage (21) is configured to generate swirl of the first fluid in a first swirl direction, and / or the at least one second passage (31) is configured to generate swirl of the second fluid in a second swirl direction. The burner of the present invention has advantages in terms of making the flame more stable, avoiding the risk of explosion, improving the combustion performance when hydrogen is burned as fuel, avoiding the backfire of the burner, reducing the ablation to the burner, avoiding the clogging of the nozzle by the heated medium, monitoring the state of the burner, etc.

The present invention discloses a fireplace for gasifying and burning fuel. The fireplace includes a housing, a burner, a gasification device, a liquid supply device, a fuel tank, and a controller. The burner is composed of a gas intake port, several horizontal portions, and several inclined portions. One end of each inclined portion located at a lower position is connected and fixed to one end of a horizontal portion, and the other ends of all the horizontal portions are connected to each other either directly or by means of a combustion chamber main body. The horizontal portions, the inclined portions, and the combustion chamber main body each have an internally hollow structure and are in communication with each other. The inclined portions are inclined upwardly with respect to the horizontal portions, and the inclined portions and the horizontal portions are combined into a three-dimensional geometric space shape. The gas intake port is provided below the burner and communicates with the interior of the burner. The horizontal portions are provided with first flame holes, the inclined portions are provided with second flame holes, and the combustion chamber main body is provided with third flame holes. When the burner is ignited, flames are burning in each of the combustion chamber main body, the horizontal portions, and the inclined portions, thereby forming a flame effect in a three-dimensional (3D) form.

A method for heating reactor using a multi-function burner comprising feeding primary fuel through an annular channel, feeding oxygen through a central channel within the annular channel, and feeding an auxiliary fuel through a central lance within the central channel to produce a flame extending into a furnace having a temperature and a pressure; wherein the flow rate of the auxiliary fuel and oxygen are increased while maintaining an equivalence ratio below 1 to increase the temperature of the furnace; wherein after the furnace temperature exceeds the auto-ignition temperature of the primary fuel, increasing the flow rate of the primary fuel to increase the equivalence ratio to be greater than 1.

The invention relates to particular burners, and e.g. to a burner comprising a central main fuel lance, a pilot fuel conduit, a main oxidant conduit, an auxiliary oxidant conduit, and optionally a secondary fuel conduit, which are arranged in a particular and advantageous way to surround each other at least in their downstream sections. The invention further relates to furnaces including the burners and methods of operating the burners. Among others, the burners of the present invention allow a particularly advantageous way of including a pilot burner as an integral part of the main burner to ignite liquid fuel flame in a cold furnace. If required, the pilot flame can assist in extending the flammability limit or operating range of the liquid fuel burner.

The present disclosure generally relates to fuel burners, for example, for use with photonic crystals as part of thermophotovoltaic power generators or with other thermal power generators. In certain aspects, fuel is supplied into a reaction tube and mixed between swirling streams of gases moving in opposite directions (e.g., clockwise and counterclockwise) within the tube. This may allow for rapid mixing and relatively complete oxidation or combustion of the fuel. Heat may be extracted from the heated exhaust and may be supplied to a thermal power generator to produce power.

A multi-tube burner system for efficient mixing of fuel and air for combustion is disclosed. The multi-tube burner system includes an air supply plenum, a multi-tube burner, and a combustor. Further, the multi-tube burner includes a set of tubes including the air supply section to receive combustion air and supply the received combustion air to a mixing section. Furthermore, the multi-tube burner includes a set of fuel pipes to receive fuel from a set of fuel inlets and supply the received fuel to a set of fuel plenums. Furthermore, a pair of fuel receiving channels receive the fuel from the set of fuel plenums and a fuel injector pin injects the received fuel from the pair of fuel receiving channels to the mixing section. Further, a set of mixing holes allow egression of the combustion air and the fuel mixture from the mixing section to the combustor.

Generally described, one or more aspects of the present disclosure relate to a rigid lance of a boiler burner device. The rigid lance includes a first tube having a first diameter, a second tube having a second diameter larger than the first diameter, a hexagonal bar connecting the first tube with the second tube, and a sealing gasket positioned between the first tube and the second tube.
