A burner apparatus () includes a fluid-based flame stabilizer for discharging a stabilized flame therefrom, a burner tile (), and fuel lances associated with the burner tile. Each of the fuel lances has a discharge nozzle (). A Coanda feature () having a Coanda surface directs a portion of the stabilized flame from the passage defined by the burner tile at the discharge end of a primary flow passage () toward at least one first fuel lance of the plurality of fuel lances to cross light the at least one first fuel lance. In another embodiment, a method of combustion includes supplying a first gaseous fuel to fuel lances of a burner apparatus and igniting and sustaining combustion of a gaseous fuel by cross lighting at the discharge nozzles of the fuel lances by flow from the fluid-based flame stabilizer along a Coanda surface of a Coanda feature toward the discharge nozzles.

Burner apparatus and method of combustion

A method for determining temperature information for a plurality of tubes in a furnace where one or more digital images provide temperature information for imaged tubes, and temperature information for non-imaged tubes is determined from the temperature information for the imaged tubes and measured temperatures of combined effluent from the imaged and non-imaged tubes.

Method for temperature data acquisition

Methods and apparatuses for separating COand sulfur-containing compounds from a synthesis gas obtained from gasification of a carbonaceous feedstock. The primary separating steps are performed using a sour pressure swing adsorption (SPSA) system, followed by an acid gas enrichment system and a sulfur removal unit. The SPSA system includes multiple pressure equalization steps and a rinse step using a rinse gas that is supplied from a source other than directly from one of the adsorber beds of the SPSA system.

Sour pressure swing adsorption process

A feed gas comprising CO, HS and His treated to produce an H-enriched product and an HS-lean, COproduct. The feed gas is separated to provide the H-enriched product and a stream of sour gas. The stream of sour gas is divided into two parts, one of which is processed in an HS removal system to form one or more streams of sweetened gas, and the other of which bypasses the HS removal system, the stream(s) of sweetened gas and the sour gas bypassing the HS removal system then being recombined to form the HS-lean, COproduct gas. The division of the sour gas between being sent to and bypassing the HS removal system is adjusted responsive to changes in the HS content of the sour gas, so as to dampen or cancel the effects of said changes on the HS content of the HS-lean, COproduct gas.

Method and apparatus for adjustably treating a sour gas

According to an embodiment, a method of operating an oxy/fuel system and an oxy/fuel system circulate a support gas in the combustion system prior to activating at least one burner, produce the combustion fluid including CO, wherein a level of the COin the combustion fluid increases as a function of time, and continue production of the combustion fluid to exceed a predetermined level of the COin the combustion fluid, for a period of time, the predetermined level being sufficient to permit the COto be purified by a COpurification unit.

Transient operation of oxy/fuel combustion system

A combustion system and method for operating a combustion system, such as a furnace or boiler. The method includes providing a burner system having one or more burner elements configured to combust solid fuel and one or more oxygen providing devices configured to introduce oxygen into the near burner zone of one or more burner flames. A sensor is provided and arranged and disposed to measure a flame parameter in the near burner zone of the burner flame associated with one or more the burner elements. The flame parameter is measured with the sensor and an oxygen flow is determined in response to the measured flame parameter. Oxygen flow is introduced to one or more locations in the combustion system with the one or more oxygen providing devices.

Oxygen control system for oxygen enhanced combustion of solid fuels

A method of configuration of combustion process control. The method includes providing a combustion system having a plurality of burner elements, a plurality of gas injection points and a controller. The gas injection points are configured to provide a support gas. One or more tasks for operation of the combustion system are determined. A plurality of groupings of the gas injection points are determined for each of the one or more tasks. An individual ranking for each of the plurality of groupings is determined in response to the one or more tasks. A composite ranking of injection points in response to the individual rankings and the controller is configured to operate the plurality of gas injection points in response to the composite ranking. A combustion system and a method for operating a combustion system are also disclosed.

Oxygen control system for oxygen enhanced combustion

A feed stream, comprising hydrogen sulphide (HS), carbon dioxide (CO), hydrogen (H) and, optionally, carbon monoxide (CO), is separated into at least a COproduct stream and an Hor Hand CO product stream. The stream is separated using a pressure swing adsorption system, an HS removal system and a further separation system, which systems are used in series to separate the stream. The method has particular application in the separation of a sour (i.e. sulphur containing) syngas, as for example produced from the gasification of solid or heavy liquid carbonaceous feedstock.

Separation of a sour syngas stream

A gaseous mixture, comprising CO, H, HS and optionally CO, is separated into an Hor Hand CO product stream (H/CO product stream), and a COenriched stream containing at least one combustible component selected from HS, H, CO and any additional combustible components present in the gaseous mixture. A support fuel stream, comprising one or more combustible components, is combusted to form a stable flame, and the COenriched stream and flame are contacted in the presence of sufficient Oto combust all or substantially all of the combustible component(s) present in said COenriched stream. A COproduct stream is formed from said combustion effluent. The support fuel stream may be generated from the process of generating or separating the gaseous mixture or from the H/CO product stream. Where the COenriched stream contains HS, the support fuel stream may also be a stream obtained off-site that comprises HS.

Method of treating a gaseous mixture comprising hydrogen, carbon dioxide and hydrogen sulphide

A feed gas comprising CO, HS and His treated to produce an H-enriched product and a COproduct. The feed gas is separated by pressure swing adsorption to provide a stream of the H-enriched product, and two streams of sour gas depleted in Hand enriched in HS and COrelative to the feed gas. One of the streams of sour gas is processed in an HS to elemental sulfur conversion system, in which HS in the sour gas is converted to elemental sulfur order to obtain a stream of sweetened gas, from which the COproduct is formed. The other of said streams of sour gas is processed in an oxidation system, in which HS in the sour gas is oxidized to SO(SOand SO) which is introduced into the HS to elemental sulfur conversion system.

Method and apparatus for treating a sour gas

NOmay be removed from a carbon dioxide feed gas comprising NOand at least one 'non-condensable' gas as contaminants by passing the feed gas at a first elevated pressure through a first adsorption system that selectively adsorbs at least NOto produce at least substantially NO-free carbon dioxide gas. The adsorption system is at least partially regenerated using a carbon dioxide-rich gas recovered from the substantially NO-free carbon dioxide gas after purification. The invention has particular application in removing NOand water from flue gas generated by oxyfuel combustion.
