Numerical modeling of atomization and combustion of liquid fuel injections and the influence of the initial gas temperature in the combustion chamber on these processes has been carried out. The temperature in the combustion chamber varied from 700 K to 1500 K for two types of liquid fuels: octane and dodecane. The distributions of liquid fuel droplets along the radii and temperature at various points in time are constructed. The influence of the initial temperature on the concentration characteristics of various types of fuel is revealed. As a result, it was found that at a pressure of over 80 bar with high turbulence, the gas temperature equal to 900 K was taken as optimal. At this temperature, the chamber is heated to high temperatures and the concentration of the resulting reaction products is the lowest. The obtained results can be applied in the construction of the liquid fuels’ combustion theory and will contribute to a deeper understanding of the complex physical and chemical phenomena that occur in combustion chambers.","PeriodicalId":414729,"journal":{"name":"ГОРЕНИЕ И ПЛАЗМОХИМИЯ","volume":"305 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116221534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In terms of the prospects for decarbonization of sectors of the economy, the use of such technologies is carbon-negative, because otherwise waste will rot in landfills and emit methane for 20 years – a greenhouse gas that is 20 times more active than carbon dioxide in terms of climate change. Thus, the carbon contribution is defined as negative in the equivalent of 188 kg of carbon dioxide per MJ compared to 20 kg for hydrogen obtained from carbon and zero for standard green hydrogen. This allowed the authors of some developments to classify the hydrogen obtained from waste as greener than green. The prospects of application of plasma technologies for hydrogen production in relation to the tasks of hydrogen energy in terms of their energy efficiency are discussed on the examples of gasification of sewage sludges and rubber crumbs of worn tires. The analysis of existing empirical dependences for determination of thermophysical characteristics of a wide range of combustible substances is carried out and the most acceptable of them for those types of carbonaceous raw materials which were subjected to gasification in the present work are selected.\u0000 ","PeriodicalId":414729,"journal":{"name":"ГОРЕНИЕ И ПЛАЗМОХИМИЯ","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117339738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In plasma-fuel systems, coal of any quality is upgraded before it is burned. In general, a plasma-fuel system is a fuel device (a device into which fuel is supplied) with a plasma source. In plasma-fuel systems, the processes of plasma preparation and/or processing of solid fuels are carried out. The basic principle of the operation of plasma-fuel systems is the organization of electrothermochemical preparation and/or processing of coal dust in electric arc plasma. The use of plasma-fuel systems makes it possible to expand the range of coals burned in the same boiler and, ultimately, reduce the sensitivity of pulverized coal boilers to fuel quality. It is shown that an important advantage of the plasma technology is the quick payback and low cost of its implementation, while reducing emissions of nitrogen oxides, sulfur and vanadium pentoxide and fuel burnout during plasma stabilization of a pulverized coal flame. This makes them practically the only real means of improving the environmental and economic efficiency of using solid fuels and replacing scarce and expensive fuel oil in the fuel balance of TPPs in the required volumes.\u0000 ","PeriodicalId":414729,"journal":{"name":"ГОРЕНИЕ И ПЛАЗМОХИМИЯ","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130070741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, direct combustion or pyrolysis of the initial solid waste, which ensures the gasification of its organic components, is usually only the first stage of the general technological process. In general, it consists of three stages. At the second stage, the gas products of the first stage are brought to a predetermined composition, at the third stage, the inorganic residue is neutralized - ash, the formation of which is up to 20% of unsorted medical waste. A promising option for the technology under consideration is the use of electric arc plasma installations. Compared to non-plasma furnaces, even those using intensive gas-dynamic operating modes, a number of significant advantages are achieved: a decrease in the volume of the furnace (while maintaining the productivity of raw materials) and a decrease in the volume of exhaust gases by about an order of magnitude with an increase in temperature in the reaction zone of the furnace to 2000–2300 °C.","PeriodicalId":414729,"journal":{"name":"ГОРЕНИЕ И ПЛАЗМОХИМИЯ","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124686462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Такой объем водорода не может быть получен за счет возобновляемых источников энергии, гидроэнергетики или атомной энергетики. До промышленного освоения энергии термоядерного синтеза единственным реальным источником такого объема водорода может быть только конверсия природного газа. Поэтому наиболее эффективный способ снижения углеродного следа энергетики – повышение эффективности использования углеводородов, в том числе их конверсии в водород. Как энергоноситель водород обладает серьезными недостатками: низким объемным содержанием энергии, большими затратами энергии на его получение, сжижение и компримирование, высокой взрывоопасностью. На начальном этапе развития водородной энергетики наиболее реальный путь преодоления сложных проблем транспортировки и хранения водорода – его рассредоточенное малотоннажное производство непосредственно в местах потребления.","PeriodicalId":414729,"journal":{"name":"ГОРЕНИЕ И ПЛАЗМОХИМИЯ","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115897677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

При этом отходы могут содержать до 50 % углерода. Малая промышленная энергетика, муниципальные котельные используют преимущественно слоевое сжигание углей. При этом коэффициент выгорания углерода составляет 50–60%, и коэффициент полезного действия котлов нередко не превышает 60%, а их экологические показатели не удовлетворяют современным требованиям. Эффективным способом решения проблемы утилизации углеотходов может оказаться перевод котлов на сжигание углей в виде водоугольной суспензии (ВУС). В статье представлены результаты авторов по технологии приготовления водоугольного топлива (ВУТ) и его сжиганию в вихревых топках котлов. Представлены данные по новому оборудованию, необходимому для реализации технологии. Показано, что и рядовые угли, и антрацит, и угольные шламы, а также отходы углеобогащения могут служить основой для производства ВУТ. Приведены примеры опытно-промышленного применения водоугольной технологии.
