    摘要: A bi-propellant rocket engine may include a primary propellant flowing in a central passageway, a secondary propellant flowing in a secondary passageway generally coaxial with central passageway and a pintle tip having a central chamber sidewall coaxial with the primary passageway and surrounding a central chamber, the central chamber sidewall having a first plurality of apertures there through so that some of the primary propellant exits the central chamber transverse to the flow of the secondary propellant in the secondary passageway. The pintle tip may have a secondary chamber sidewall, substantially thicker than the primary chamber sidewall, surrounding a secondary chamber downstream of and in fluid communication with the primary chamber, the secondary chamber sidewall having a second plurality of apertures there through so that some of the primary propellant exits the secondary chamber transverse to the flow of the secondary propellant in the secondary passageway. The pintle tip may have an end wall generally traverse to the flow of the primary propellant in the central passageway and adjacent the secondary chamber sidewall so that the flow of primary propellant through the secondary chamber sidewall cools a downstream face of the end wall during combustion of the mixed propellants adjacent the downstream face of the end wall. The pintle tip may be used for mixing a first liquid with a second liquid.

    摘要: The invention relates to the field of power machine building and may be used in mixing devices of gas generators for driving gas turbines, in particular, for liquid-propellant rocket engines. A gas generator comprises a cover with a hole, a bottom with a mixing chamber, a housing with an axial duct communicating with the hole in the cover. The housing is fastened in the cover hole and/or in the mixing chamber of the bottom. Grooves are made uniformly along the circumference of the cross section of the housing in the bottom and/or on the housing. The hole in the cover and the axial duct are designed to supply propellant, and the space between the cover and the bottom and the grooves in the bottom and/or on the housing are designed to supply an oxidizer. A propellant space is made in the cover, and the axial duct communicates through the propellant space with the hole in the cover by means of tangential propellant supply holes. An annular oxidizer duct and a cylindrical mixing chamber are additionally made in the module housing. The annular oxidizer duct is placed concentrically to the axial duct and communicates coaxially with the cylindrical mixing chamber, and by tangential oxidizer supply holes communicates with the space between the cover and the bottom.

    摘要: A method of minimizing the production of SO.sub.x and NO.sub.x in the burning of a fuel containing significant amounts of SO.sub.x and NO.sub.x precursors in which the fuel is treated to remove significant amounts of SO.sub.x precursors without the removal of significant amounts of NO.sub.x precursors and the fuel is thereafter burned in a two-stage, rich-lean burning step in which significant amounts of the NO.sub.x precursors are converted to N.sub.2. Treating the fuel to remove SO.sub.x precursors is preferrably carried out in the presence of an oxidizing agent, such as H.sub.2 O.sub.2, a reducing agent, such as hydrogen, and/or steam, and still more preferably, the oxidizing agent, the reducing agent and steam are generated by burning an auxiliary fuel and passing the effluent thereof to the step of treating the fuel to remove SO.sub.x precursors.

    摘要: There is a process for operating a utility boiler. The process has the following steps: a) continuously adding one or more slag control agents, one or more oxygen-generating agents, and a fuel oil to a furnace of the utility boiler; b) providing air to the furnace; c) burning the fuel oil to generate heat and an exhaust gas; d) periodically or continuously varying the dosage rates of the one or more slag control agents and/or the one or more oxygen-generating agents to maintain to substantially maintain one or more emissions variables in the exhaust gas within pre-determined limits. There is also a method for reducing emissions from a utility boiler and a method for reducing slag deposits within a utility boiler.

    摘要: A method for implementing a system and a device for enhancing the starting process of a turbine engine by use of at least one solid mass of oxidizing-species-releasing material, ORM, selected as a solid oxidizer, or SO, and/or as an oxidizing-species-releasing burning substance, or ORBS. The ORM is introduced into the combustion chamber of the turbine engine and the starting process of the turbine engine is initiated, by help of the igniter and in association with the mass of ORM, to enhance the starting process. In operation, an ORM selected as an SO releases gaseous oxygen when heated to decompose, while an ORM chosen as an ORBS discharges oxidizing species when ignited to burn. An ORM such as an SO or an ORBS may operate alone or in various combinations of both. The ORM is configured to release a predetermined mass flow rate of oxidizing species or of gaseous oxygen.

    摘要: Apparatus and processes are provided for combusting hydrocarbon-containing waste fuel with an oxidizer, preferably liquid oxygen, and producing a substantially clean exhaust gas and a separate high purity steam product (e.g., superheated steam) that can be used to generate electrical power. The apparatus includes a plurality of combustion chambers in series with means to control the combustion temperature while facilitating complete combustion. The apparatus and method are useful for transforming waste materials, particularly solid and liquid wastes, such as the rubber from scrap tires into non-hazardous materials and energy.

    摘要: At least one solid mass of oxidizing-species-releasing material (ORM), selected as a solid oxidizer (SO), and/or as oxidizing-species-releasing burning substance (ORBS) is used as a device for enhancing the starting process of a turbine engine under various ambient conditions. The ORM is introduced into the combustion chamber of the turbine engine and the starting process of the turbine engine is initiated, by help of the igniter and in association with the ORM to enhance the starting process. In operation, an ORM selected as an SO releases gaseous oxygen when heated to decompose, while an ORM chosen as an ORBS discharges oxidizing species when ignited to burn. An ORM such as an SO or an ORBS may operate alone or in various combinations of both. The ORM is configured to release a predetermined mass flow rate of oxidizing species or of gaseous oxygen.
