Burner Device for the Partial Oxidation of Gaseous Gasification Materials

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a specially designed burner device for the partial oxidation of gaseous materials used in gasification processes. Unlike conventional burners that tend to cause a recirculating flow inside the gasifier, this invention establishes a predominantly plug (piston-like) flow, improving reaction efficiency. The burner incorporates multiple insulation layers, cooling channels, dedicated supply lines for fuels, oxidants, and shielding gases (like steam or CO2), and a unique structural arrangement to separate and safely inject these reactants at extremely high temperatures and pressures.

Use CasesContent extracted from patent full text and abstract with AI.

• Producing synthesis gas (syngas) from natural gas or other gaseous hydrocarbons for use in chemical manufacturing (e.g., ammonia or methanol production).
• Hydrogen generation plants that rely on autothermal or partial oxidation reformers.
• Integrated gasification combined cycle (IGCC) power plants, where gasification is used for cleaner electricity production from fossil fuels.
• Production of synthetic fuels (Fischer-Tropsch process) via gasification of gaseous feedstocks.
• Any industrial process requiring efficient, safe, and high-performance gasification of gaseous materials under extreme operating conditions.

BenefitsContent extracted from patent full text and abstract with AI.

• Improved reaction efficiency by promoting plug flow instead of recirculating flow, leading to faster and more complete conversion of reactants.
• Enhanced safety due to dedicated shielding gas layers and segregated injection of reactants, preventing undesired reactions or hazardous mixing inside the burner.
• Superior temperature and pressure management through advanced insulation and active cooling, allowing safe operation at up to 1600°C and high pressures (up to 100 bar).
• Flexibility to handle different process modes (both autothermal reforming and partial oxidation) and variable feedstock compositions.
• Increased burner and reactor lifespan as a result of improved cooling and thermal stress management features.
• Minimized risk of gas leaks and backflow due to pressure differentials and robust mechanical design.

Patent Abstract

The invention relates to burner devices for the partial oxidation of gaseous gasification materials. These are in particular characterized in that the reactants can be supplied to the gasifier internal space - which is pressurized and at temperatures of up to 1600°C - such that, instead of a predominantly recirculation flow, a predominantly plug flow is established in the gasifier internal space. To that end, the burner device has a first insulation covering the gasifier internal space, a cooling device having one coolant supply line and one coolant discharge line, a second insulation, a gasification material distributor space which has a gasification material supply line and is on either the second insulation or the cooling device with a second insulation, a shield gas space having a shield gas supply line above the gasification material distributor space, a cover covering the shield gas space and having a distributor for oxygen or oxygen-containing gasification material in conjunction with a supply line, burners and a third insulation as an insulation surrounding the cooling device, the gasification material distributor space and the shield gas space.
