Abstract
A Venturi device with a primary flow path and a secondary flow path introduced into the primary flow path, wherein a flow of one or more flowable mediums in the primary flow path and the secondary flow path creates a vortex generating a suction at an inlet of the Venturi device. A particulate burner system can be used to combust fuel emission byproducts by injecting fuel and air into a housing having a bottom plate with a round bottom opening for burners to inject fuel into a combustion chamber and a top plate with a round top opening for exhausting fuel emissions. A thruster system can be used to propel munition for deep earth penetration by using a thruster system having a transfer cone connected to a munition body.
Claims23
A particulate burner system for combustion of fuel emission byproducts, the system comprising:
- a housing forming a combustion chamber, the housing comprising:
- a bottom plate with a round bottom opening for burners configured to inject fuel into the combustion chamber;
- a top plate with a round top opening for exhausting fuel emissions from the combustion chamber, the round bottom opening and the round top opening aligned along a central axis of the housing;
- and
- a round sidewall extending between the bottom plate and the top plate about the central axis and connected to the bottom plate and the top plate, the round sidewall comprising a round sidewall opening for directing air into the combustion chamber, the round sidewall opening tangential to an inner periphery of the round sidewall to inject air into the combustion chamber tangential to the inner periphery of the round sidewall to centrifugally direct air in an airflow direction along the inner periphery of the round sidewall and entrain fuel from the round bottom opening into the air moving in the airflow direction along the inner periphery;
- a deflection plate positioned in the combustion chamber and connected to at least one of the bottom plate or the top plate, the deflection plate axially extending along the central axis and extending along the round bottom opening, the deflection plate positioned between the round bottom opening and the round sidewall opening to mitigate flow of fuel from the round bottom opening to the round sidewall opening and to mitigate flow of air from the round sidewall opening to the round bottom opening;
- a plurality of fins positioned in the combustion chamber and connected to the bottom plate, the plurality of fins radially extending in the combustion chamber proximate from the round bottom opening toward the inner periphery of the round sidewall, wherein a first radial extent of a first fin of the plurality of fins from the central axis is less than a second radial extent of a last fin of the plurality of fins from the central axis, wherein a first axial extent of the first fin along the central axis is less than a second axial extent of the last fin along the central axis, wherein the first fin is positioned adjacent the deflection plate downstream of the deflection plate along the airflow direction, and wherein the last fin is positioned adjacent the deflection plate upstream of the deflection plate along the airflow direction,
- wherein the first radial extent of the first fin of the plurality of fins is less than the second radial extent of the last fin of the plurality of fins and the first axial extent of the first fin along the central axis is less than the second axial extent of the last fin along the central axis to allow air to flow from the round sidewall opening to minimize backpressure by the first fin on flow of air from the round sidewall opening,
- wherein radial extents of other fins of the plurality of fins are longer relative to the first radial extent of the first fin to direct fuel further toward the inner periphery of the round sidewall as the air moves in the airflow direction along the inner periphery and entrains fuel toward the inner periphery along the plurality of fins for combustion of fuel emission byproducts along the round sidewall;
- and
- a Venturi device in fluid communication with the round sidewall opening, the Venturi device comprising:
- an inlet configured to receive a primary flow comprising compressed air;
- an outlet in fluid communication with the round sidewall opening to direct the primary flow through the round sidewall opening into the combustion chamber;
- and
- a body disposed between the inlet and the outlet, the body comprising:
- a converging portion and a diverging portion, wherein a movement of the primary flow through the converging portion and the diverging portion produces a Venturi effect, pulling the primary flow in through the inlet;
- and
- a secondary input disposed between the converging portion and the outlet, the secondary input configured to direct a secondary flow of fluid into the primary flow to create a vortex for producing a suction at the inlet to pull the primary flow through the inlet and into the body to increase the primary flow through the outlet.
