Abstract:
Power cycle generation equipment is operated in a more efficient and economical manner by using an uncooled (and potentially uncleaned) fuel gas supplied to the equipment directly from a gasification process, i.e., without first quenching or pressurizing the gas. In one embodiment, a burner used in conjunction with the power cycle generation equipment accepts such fuel gas directly from a syngas generator (or perhaps after particulate removal). The burner preferably operates with fuel gas and oxidizer inputs reversed as compared to existing configuration.
Abstract:
A method for the combustion of ammonia, wherein a first combusion chamber (2) receives ammonia and hydrogen in controlled proportions, and an oxygen-containing gas such as air. Combustion of the ammonia and hydrogen produces nitrogen oxides among other combustion products. A second combustion chamber (13) receives the nitrogen oxides along with further ammonia and hydrogen in further controlled proportions along with further oxygen-containing gas such as air. The nitrogen oxides are combusted into nitrogen and water.

본 발명은 서로 격리되지 않은 하나의 공간에서 산화반응과 환원반응이 분리되어 일어나도록 하는 환원용버너 및 이를 이용한 합성가스 리사이클링 시스템에 관한 것으로서, 연료공급공(210)과 다수의 산소공급공(220)이 구비된 환원용버너(200)를 반응로(100)의 벽체(101)에 다수 설치하여 반응로의 버너를 구성하되 환원용버너(200)의 헤드(201) 선단에 환원용버너(200)점화 후 연료를 산화시킬 수 있는 양보다 적게 공급되는 산소를 완전히 없앨 수 있도록 버너 깊이를 충분한 깊이로 연소실(202)을 구비하여 연소실(202) 내부에서는 산소의 산화(연소)반응이 충분히 되게 하고 반응로(100) 내부에서는 유입된 산소가 없고, 불완전 연소한 연료(C, C0, H2)와 복사열과 환원용버너 내에서 산화에 의해 발생된 H2O분자나 CO2분자가 유입되면서 1200 이상의 고온으로 가열된 후에 H2O분자나 CO2분자에 의한 환원 반응만이 일어나게 되어 본 발명인 서로 격리되지 않은 하나의 공간에서 산화반응과 환원반응이 분리되어 일어나도록 하는 환원용버너를 얻을 수 있다. 또한 불완전 연소로 유입된 합성가스(H2와 CO의 혼합가스)는 다시 포집하여 재사용하기 때문에 문제될 게 없다. 그리고, 상기와 같이 깊이가 깊은 연소실(202)이 헤드 선단에 구비된 환원용버너(200)와 반응로(100)로 구성되는 서로 격리되지 않은 하나의 공간에서 산화반응과 환원반응이 분리되어 일어나도록 하는 환원용버너 외에, 혼합가스배출공(120)과 연결된 혼합가스 회수라인(121)를 통해 포집된 가스를 냉각 및 압축시키는 냉각압축기(400); 냉각압축기(400)에서 냉각압축된 혼합가스를 받아 저장하였다가 상기 반응로(100)의 환원용버너(200)로 공급하는 저장탱크(500); 산소공급공(220)으로 산소를 공급하는 산소발생기(600);를 구비하면 반응로에서 생성된 합성가스를 포집 저장하였다가 환원용버너에 연료로 공급하여 재사용할 수 있는 합성가스 리사이클링 시스템을 얻을 수 있다.
Abstract:
A combustion method in which a fuel gas having a velocity less than 50 feet/second is mixed with a stream of motive gas having a velocity of a least 200 feet/second to form a stream with a velocity greater than 50 feet/second, and the mixed stream is combusted with oxidant. In particular the fuel with low velocity is produced when heated flue gas heats a regenerator through which a mixture of fuel and flue gas is then passed to undergo endothermic reactions that produce syngas which is fed into a furnace together with a motive gas stream. The motive gas stream can be fed inside the firing port, in the duct for the fuel or from points in a wall outside of the furing port at a specific distance. All embodiments lead to better control of the shape of the flame.

Ela compreende etapas realizando a gaseificação da matéria prima contendo carbono por meio de um fluxo gasoso contendo essencialmente CO 2 , sendo a oxidação do fluxo gasoso obtida após a gaseificação pelos portadores de oxigênio e a oxidação dos portadores de oxigênio desativados obtidos. O processo permite valorizar a energia global gerada pelo conjunto dessas etapas para alimentar um sistema de geração de eletricidade tal como um turbo-alternador. A invenção corresponde igualmente a um sistema para executar tal processo.
