A siding tool for siding installation in building construction to efficiently measure the distance between adjacent siding panels and to install siding. The body of the siding tool is preferably approximately 3/16&#x2033; ( 3/16 inches) wide, and a depth of approximately two inches (2&#x2033;). The width and depth are used to measure distances according to building code. The body has a lip at one end that extends from the base of the body. The lip is configured to position the siding tool in place by catching the bottom edge of a panel of siding that has been placed. The lip of the siding tool is also configured for a user to position the siding tool upside down and use the lip to draw measurement lines.

Siding tool

A fuel, an oxidant, and a diluent can be introduced to a combustion zone, wherein the oxidant comprises air, oxygen-enriched air, or oxygen-lean air. At least a portion of the fuel can be combusted to produce an exhaust gas comprising, nitrogen, nitrogen oxides, and carbon monoxide. The exhaust gas can be expanded to produce mechanical power and an expanded exhaust gas. A concentration of at least one of oxygen, hydrogen, nitrogen oxides and carbon monoxide, in the exhaust gas or the expanded exhaust gas or both can be determined, and an amount of the oxidant or the fuel introduced to the combustion zone, or both, can be adjusted based on the determined concentration to produce an exhaust gas containing a combined amount of oxygen and carbon monoxide of less than about 2 mol % and a nitrogen concentration ranging from 20 mol % to 75 mol %. The diluent to the combustion zone can include at least a portion of the exhaust gas containing a combined amount of oxygen and carbon monoxide of less than 2 mol % and a nitrogen concentration ranging from 20 mol % to 75 mol %.

Systems and methods for controlling combustion of a fuel

The present invention relates to methods and systems for controlling a combustion reaction and the products thereof. One embodiment includes a combustion control system having an oxygen supply stream and a high concentration carbon dioxide stream, mixing the streams to form an oxygenation stream substantially comprising oxygen and CO2 and having an oxygen to CO2 ratio, then mixing the oxygenation stream with a combustion fuel stream and combusting in a combustor to generate a combustion products stream having a temperature detected by a temperature sensor, the data from which is used to control the flow a carbon dioxide diluent stream to produce a desired temperature of combustion. The system may also include a control system configured to regulate the flow of the oxygen supply stream based on the flow rate and composition of the combustion fuel stream. The system may also include a gas turbine with an expander and having a load and a load controller in a feedback arrangement. Other embodiments include a hydrocarbon analyzer and multiple fuel streams that may be combined to form the combustion fuel stream.

Methods and systems for controlling the products of combustion

The present techniques are directed to a flexible liquefied natural gas (LNG) plant that may be tied to an external electric grid for importing or exporting electric power. Exemplary embodiments provide a method for producing LNG that includes producing a base load capacity of refrigeration capacity for LNG production from a first compression system. Electricity may be produced from a second compressor string if electricity is needed by an external power grid, or a second amount of refrigeration capacity may be provided by the second compressor string is natural gas feed is available and the external grid does not need power.

Systems and methods for an oxy-fuel type combustion reaction are provided. In one or more embodiments, a combustion system can include at least two mixing zones, where a first mixing zone at least partially mixes oxygen and carbon dioxide to produce a first mixture and a second mixing zone at least partially mixes the first mixture with a fuel to produce a second mixture. The combustion system can also include a combustion zone configured to combust the second mixture to produce a combustion product. In one or more embodiments, the first mixture can have a spatially varied ratio of oxygen-to-carbon dioxide configured to generate a hot zone in the combustion zone to increase flame stability in the combustion zone.

Combustor systems and combustion burners for combusting a fuel

Methods and systems for low emission power generation in hydrocarbon recovery processes are provided. One system includes integrated pressure maintenance and miscible flood systems with low emission power generation. An alternative system provides for low emission power generation, carbon sequestration, enhanced oil recovery (EOR), or carbon dioxide sales using a hot gas expander and external combustor. Another alternative system provides for low emission power generation using a gas power turbine to compress air in the inlet compressor and generate power using hot carbon dioxide laden gas in the expander. Other efficiencies may be gained by incorporating heat cross-exchange, a desalination plant, co-generation, and other features.

Low emission power generation and hydrocarbon recovery systems and methods

A method for in situ heating of an organic-rich rock formation is provided. Preferably the organic-rich rock formation comprises kerogen. The method may include the steps of providing a first wellbore extending at least to a depth of the organic-rich rock formation, and providing a second wellbore also extending to a depth of the organic-rich rock formation and intersecting the first wellbore. The method may also include injecting air and a combustible fuel into the first wellbore, and providing a downhole burner in the wellbore so as to cause the air and the combustible fuel to mix and to combust at substantially the depth of the organic-rich rock formation. The method may further include, circulating combustion products into and up the second wellbore such that a pyrolysis zone is created from the first wellbore and second wellbores that provides substantially complete pyrolysis of the organic-rich rock formation between the first wellbore and the second wellbore. Operating conditions may be set or controlled so that the pyrolysis zones surrounding the first and second wellbore mate so to minimize underheated and overheated regions.

Downhole burner wells for in situ conversion of organic-rich rock formations

A method for in situ heating of a selected portion of a targeted organic-rich rock formation such as an oil shale formation is provided. The method includes the steps of providing casing in a wellbore extending to a depth within or below the selected portion of the organic-rich rock formation, and also providing a tubing within the casing. An annular region is formed between the tubing and the surrounding casing. Air or other oxidant and a combustible fuel are injected into the wellbore. Either the air or the combustible fuel is in stoichiometric combustion excess. The method also includes providing hardware in the wellbore so as to cause the air and the combustible fuel to mix and to combust at substantially the depth of the organic-rich rock formation. The hardware may include more than one burner. Insulation may be placed along the tubing adjacent the first burner in order to reduce the heat transfer coefficient within the tubing and to provide a more uniform temperature within the annulus.
