[001] O seguinte relatório descritivo para invenção se refere ao desenvolvimento de um gerador de vapor saturado a baixa pressão que consiste em atomizar água transformando em estado de névoa, por intermédio de bicos atomizadores, onde dita nevoa será injetada em um duto de calor dinâmico, dotado de alguma fonte de calor capaz de propiciar aíta temperatura ao ambiente, de modo que as gotfculas de água se transformem em vapor saturado quase instantaneamente.  The following descriptive report for invention relates to the development of a low pressure saturated steam generator which consists of atomising water into a mist state by means of atomizing nozzles where said fog will be injected into a dynamic heat duct , provided with some heat source capable of providing ambient temperature therein, so that the water droplets become saturated vapor almost instantaneously.
ESTADO DA ARTE STATE OF ART
[002] Vapor é utilizado em uma vasta gama de aplicações, desde o uso doméstico até industrial. Aplicações comuns para vapor são, por exemplo, processamento de alimentos, processos aquecidos a vapor em usinas, fábricas e turbinas movidas a vapor em usinas de energia elétrica, processamentos químicos, mas os usos de vapor na indústria vão muito além disso, tais como: aquecímento/esteriíização, propulsão/movimento, força motriz etc.  [002] Steam is used in a wide range of applications, from domestic to industrial use. Common applications for steam are, for example, food processing, steam-heated processes at power plants, steam-powered plants and turbines at power plants, chemical processing, but steam uses in industry go far beyond this, such as: heating / sterilization, propulsion / movement, power, etc.
[003] A forma mais comum para gerar vapor é por intermédio de uma caldeira. A maioria das caldeiras é indireta na medida em que elas queimam algum tipo de combustível (lenha, resíduos, gás, óleo etc.) para aquecer as paredes de um trocador de calor. Fluxos de água são empregados do outro lado da parede trocadora de calor (normalmente dentro de tubos). A água nos tubos aquece até o ponto de ebulição, conforme a água passa através da caldeira. A água está, assim, indiretamente aquecendo em vapor. Se água for aquecida além do ponto de ebulição, ela se transforma em vapor, ou água em estado gasoso. No entanto, nem todo vapor é igual. As propriedades do vapor variam gradativamente dependendo da pressão e temperatura na qual ele está sujeito. [003] The most common way to generate steam is by means of a boiler. Most boilers are indirect in that they burn some kind of fuel (wood, waste, gas, oil, etc.) to heat the walls of a heat exchanger. Water flows are employed on the other side of the heat exchanger wall (usually inside pipes). The water in the tubes heats up to the boiling point as the water passes through the boiler. The water is thus indirectly heating in steam. If water is heated beyond the boiling point, it turns into steam, or water in the gaseous state. However, not all steam is the same. The properties of the vapor vary gradually depending on the pressure and temperature at which it is subjected.
[004] O vapor saturado ocorre em temperaturas e pressões onde o vapor (gás) e água (líquido) podem coexistir. Em outras palavras, isto ocorre quando a taxa de vaporização da água é igual a taxa de condensação. Deste modo, quando toda a água foi fervida em vapor, e nenhum calor adicional foi adicionado, o vapor é considerado "saturado". Se a água não foi completamente fervida, mas tem um pouco de água condensada ainda neia, o vapor é considerado como "úmido". Se mais calor foi adicionado passado o ponto de ebulição de toda a água, e todo o vapor foi elevado em temperaturas acima do ponto de ebulição da água na pressão dada, o vapor é considerado "superaquecido". Dependendo da temperatura do vapor requerido, e se é ou não é importante que o vapor seja completamente gasoso ou se beneficie de ser úmido, a caldeira está configurada para aumentar o vapor para temperatura e estado desejados.  [004] Saturated steam occurs at temperatures and pressures where vapor (gas) and water (liquid) can coexist. In other words, this occurs when the rate of vaporization of water equals the rate of condensation. Thus, when all water has been boiled in steam, and no additional heat has been added, the steam is considered to be "saturated." If the water has not been completely boiled, but has some condensed water still neia, the steam is considered as "moist." If more heat was added past the boiling point of all water, and all the steam was raised at temperatures above the boiling point of the water at the given pressure, the steam is considered to be "superheated." Depending on the required steam temperature, and whether or not it is important that the steam is completely gaseous or benefits from being moist, the boiler is configured to increase the steam to desired temperature and state.
[005] Também é conhecida a geração direta de vapor, através de combustão de oxicombustfvel, onde um combustível contendo hidrogénio e/ou carbono é queimado com oxigénio. O hidrogénio no combustível reage com o oxigénio para diretamente formar água. A temperatura de tais reações é tal que normalmente a água é formada no estado gasoso na forma de vapor superaquecido. Mais tipicamente com combustão de oxicombustível, a água também é adicionada em uma câmara de combustão para esfriar o vapor de alta temperatura produzido pela combustão do combustível com o oxigénio. Essa água adicional é aquecida diretamente em vapor e é misturada com o vapor gerado pela combustão do combustível com o oxigénio. [006] Um gerador de vapor com uma câmara de combustão na quai o oxigénio e um combustível contendo hidrogénio são direcionados para a combustão nela é descrito no documento US 20100224363. O gerador de gás também inclui saídas de água e uma saída para uma mistura de vapor e CO2 gerado dentro do gerador de gás. A mistura de vapor e CO2 pode ser usada para vários processos diferentes, com alguns tais processos resultando em recirculação de água do processador de volta para a entrada da água do gerador de gás. Direct steam generation is also known through combustion of oxyfuel, where a fuel containing hydrogen and / or carbon is burned with oxygen. Hydrogen in the fuel reacts with oxygen to form water directly. The temperature of such reactions is such that normally water is formed in the gaseous state in the form of superheated steam. More typically with combustion of oxyfuel, water is also added in a combustion chamber to cool the high temperature vapor produced by the combustion of the fuel with oxygen. This additional water is heated directly in steam and is mixed with the vapor generated by the combustion of the fuel with oxygen. A steam generator with a combustion chamber in which oxygen and a hydrogen-containing fuel are directed to combustion therein is described in US 20100224363. The gas generator also includes water outlets and an outlet for a mixture of steam and CO 2 generated within the gas generator. The vapor and CO 2 mixture can be used for several different processes, with some such processes resulting in recirculation of water from the processor back into the water inlet of the gas generator.
[007] O documento US 7780152 descreve um gerador de vapor de combustão direta, que compreende um queimador de difusão de fluxo de redemoinho em uma zona de combustão dentro de uma câmara, compreendendo 0 dito queimador, pelo menos, uma entrada de combustível e pelo menos uma entrada de fluido contendo oxigénio, e em que pelo menos uma das referidas entradas está adaptada para criar uma zona de recirculação de vórtice, derrtro de uma flama aerodinamicamente estável implantada ao longo de um núcleo axial da referida zona de combustão dentro da referida câmara, e em que a referida chama é de intensidade suficiente para produzir caior latente de vaporização de água correspondente à pressão de operação; e em que a referida câmara é definida por uma parede que compreende uma entrada adaptada para introduzir um fluxo giratório axiai de água ao longo de uma superfície interior da referida parede, 0 dito fluxo de água que define a referida zona de combustão e isolando a referida parede da referida chama. Uma aplicabilidade particular é encontrada na geração de vapor no espaço compacto.  US 7780152 discloses a direct combustion steam generator comprising a swirl flow diffusion burner in a combustion zone within a chamber, said burner comprising at least one fuel inlet and at least one fuel inlet. less one oxygen-containing fluid inlet, and wherein at least one of said inlets is adapted to create a vortex recirculation zone, from an aerodynamically stable flame implanted along an axial core of said combustion zone within said chamber , and wherein said flame is of sufficient intensity to produce latent heat of water vaporization corresponding to the operating pressure; and wherein said chamber is defined by a wall comprising an inlet adapted to introduce an axially rotatable flow of water along an inner surface of said wall, said flow of water defining said combustion zone and isolating said wall of said flame. A particular applicability is found in the generation of steam in the compact space.
PROBLEMAS DA TÉCNICA  PROBLEMS OF THE TECHNIQUE
[008] A geração de vapor por meio de caldeiras pode ser de dois tipos: caldeiras fiamo tubulares, onde os gases quentes providos de água circulam pelos tubos de troca, transferindo o calor para a água, normalmente operam com baixas capacidade de produção e pressão; ou as caldeiras aquatubulares, onde essa água circula pelos tubos e entre dois vasos comunicantes recebendo calor dos gases quentes gerado no queimador. São caldeiras com capacidades maiores de produção e altas pressões. Também, tem as caldeiras mistas. The generation of steam by means of boilers can be of two types: tubular hot boilers, where the hot gases provided by water circulate through the exchange tubes, transferring the heat to the water, usually operate with low production capacity and pressure; or aquatubular boilers, where this water circulates through the tubes and between two communicating vessels receiving heat from the hot gases generated in the burner. They are boilers with higher production capacities and high pressures. Also, there are the mixed boilers.
[009] Independentemente do modo de trabalho, uma caldeira é um equipamento que requer cuidados especiais em sua manutenção, exigem profissionais habilitados para seu manuseio e podem ser muito caras.  [009] Regardless of the way of working, a boiler is an equipment that requires special care in its maintenance, require professionals qualified for its handling and can be very expensive.
[010] O sistema de geração direta de vapor por meio de oxicombustível é mais barato do que uma caldeira convencional e não requer tanta manutenção. No entanto, o sistema opera com temperaturas muito elevadas, da ordem de 1000ºC, gerando vapor superaquecido.  [010] The system of direct steam generation through oxyfuel is cheaper than a conventional boiler and does not require as much maintenance. However, the system operates at very high temperatures, on the order of 1000 ° C, generating superheated steam.
[011] Também, é importante observar que o documento US 20100224363 (oxicombustível) descreve um método de geração de gás misturado de C02 e vapor, onde o gerador de gás inclui múltiplas câmaras adjacentes com entradas separadas de água passando para o gerador de gás entre as câmaras adjacentes, de tal forma que as temperaturas nas câmaras adjacentes sejam progressivamente mais baixas conforme a distância a partir da câmara de combustão aumentar. Neste sistema, as câmaras adjacentes devem ser resfriadas com água para evitar o superaquecimento.  It is also important to note that US 20100224363 (oxyfuel) describes a method of generating mixed gas of CO2 and steam, wherein the gas generator includes multiple adjacent chambers with separate water inlets passing to the gas generator between the adjacent chambers in such a way that the temperatures in the adjacent chambers are progressively lower as the distance from the combustion chamber increases. In this system, adjacent chambers must be cooled with water to prevent overheating.

Deste modo, não se trabalha com vapor superaquecido. In order to solve the above problems the invention proposes the development of a continuous low pressure saturated steam generator with water atomization in micro droplets, which consists of atomising water into a mist state, for This is done by means of atomizing nozzles, where said mist will be injected into a dynamic duct, where the heat can be directly, through burners or indirectly, these heating systems providing a high temperature to the environment, so that the droplets of water become saturated vapor almost instantly.
