The article contains the results of the systematic scientific-research and research-development work, which ensured the implementation of innovating power efficient and ecological technologies, aimed at the increase of reliability and economic efficiency of heat supply to industrial facilities and populated areas in the regions, experiencing deficiency of traditional power-generating fuel. The article presents the solution of relevant scientific problems, results of the researches, on the basis of which the new structures of combined low emission burner device with staged burning of gaseous and liquid fuels and fire-tube boilers with increased efficiency (not less than 94 %) are suggested. The results of experimental researches on factory test benches and operation facilities in operating load range from 40 to 100 % of nominal load, confirmed the boiler efficiency of more than 94 % – this is by 4–6 % higher than existing indicators in case of burning raw oil and fuel oil and by 2–4 % higher than in case of burning natural gas. The protection of boiler from low temperature sulphur corrosion is provided by the compact remote economizer. The developed equipment reduces emissions of nitrogen oxide into the atmosphere by 25–30 % in comparison with the regulatory levels and by 10–15 % in comparison with the best foreign analogues. Boilers and burners are supplied to the facilities in finished form as a part of compact modular boilers, which significantly reduces commission deadlines.

Tasmania is the only state in Australia which is not supplied with natural gas, and yet a significant gas, condensate and oil resource lies off the Tasmanian coast awaiting development.The Yolla field, discovered by Amoco, SAGASCO Resources, the Bass- Cue Group, Romsey Resources and Southeastern Petroleum in 1985, has sufficient resource potential to support the development of a natural gas supply infrastructure in Tasmania. The field is rich in LPG and condensate and also contains a small oil pool. Tests on the Yolla 1 well were the first in the Bass Basin to flow hydrocarbons and they demonstrated that the field has excellent reservoir properties for commercial development.The keys to the initiation of a gas, condensate and oil development in Tasmania are the need for a significant market for the natural gas and an oil price somewhat better than US$20 per barrel. While there are many major manufacturing and mineral processing plants on the Tasmanian North Coast which would benefit from the stimulus provided by a reliable natural gas pipeline supply, these industries alone provide insufficient load to make an offshore gas development economic. The Bell Bay power station, a thermal power station of 240 MW capacity fired on fuel oil, could, if converted to gas and operated to provide base load supply, generate sufficient base gas demand to enable a project development to proceed.A gas condensate development would provide a substantial stimulus to the Tasmanian economy through:direct investment in the project itself;fostering further development of processing industries on the North Coast;providing cheaper electricity than available from new hydroelectric and coal fired stations;contributing significantly to Tasmanian self- sufficiency in liquid fuels; andreleasing scarce government capital for debt reduction or other uses.

The gas turbine market tends to drive development towards higher operational and fuel flexibility. In order to meet these requirements the GT13E21 combustion system with the AEV burner has been further developed to extend the range of fuels according to GE fuel capabilities. The development includes operation with diluted natural gas, gases with very high C2+ contents up to liquefied petroleum gas on the gaseous fuels side and non-standard liquid fuels such as biodiesel and light crude oil. Results of full scale high pressure single burner combustion test in the test facilities at DLR-Köln are shown to demonstrate these capabilities. With these tests at typical pressure and temperature conditions safe operation ranges with respect to flame flashback and lean blow out were identified. In addition, the recent burner mapping at the DLR in Köln results in emission behavior similar to typical fuels as natural gas and fuel oil #2. It was also possible to achieve low emission levels with liquid fuels with a high fuel bound nitrogen content. Based on these results the GT13E2 gas turbine has demonstrated capability with a high variety of gaseous and liquid fuel at power ranges of 200 MW and above. The fuels can be applied without specific engine adjustments or major hardware changes over a whole range of gas turbine operation including startup and GT acceleration.

Capital Construction

One of the most important issues for modern domestic power industry is the creation and further widespread introduction of solid propellant energy units for super-critical steam parameters with high efficiency (43–46%) and improved environmental parameters. This will significantly reduce the use of natural gas.At the same time, one of the major drawbacks of the operation of pulverized coal power units is the need to use a significant amount of fuel oil during start-up and shutdown of boilers to stabilize the burning of the coal torch in the variable boiler operating modes.In this regard, solid fuel TPPs need to be provided with fuel oil facilities, with all the associated problems to ensure the performance (heating of fuel oil in winter), reliability and safety. All of the above problems increase both the TPP capital construction costs, and the electricity generating cost.A practical solution to the above problems at present is the use of a plasma technology for coal torch ignition based on thermochemical preparation of fuel for combustion. The materials of the developments of JSC “NPO CKTI” on application of plasmatrons in boilers of thermal power plants at metallurgical complexes of the Russian Federation are also considered.Plasma ignition systems for solid fuels in boilers were developed by Russian specialists and were introduced at a number of coal-fi red power plants in the Russian Federation, Mongolia, North Korea, and Kazakhstan. Plasma ignition of solid fuels is widely used in China for almost 30% of power boilers.The introduction of plasma-energy technologies will improve the energy efficiency of domestic solid-fuel thermal power plants and can be widely implemented in the modernization of boilers.During the construction of new TPPs, the construction of fuel oil facilities can be abandoned altogether, which will reduce the capital costs of the construction of thermal power plants, reduce the construction footprint, and increase the TPP safety.

Recently, prospective direction of the combustion theory development is the preparation of fuel compositions and study of the composite fuels ignition characteristics, for example, in the form of emulsions and suspensions. Such fuels and their combustion processes are characterized by higher environmental, energy, economic, and operational properties. Of great interest is the use of gel fuels prepared by thickening emulsions and suspensions to the state of elastically deformable materials for the aerospace industry and thermal power engineering. Gel fuels have advantages over widespread liquid fuels in environmental and fire safety aspects of storage processes, transportation, and combustion.

The nitrogen oxides in a flame of burning fuel can be created by many mechanisms. The amount of NOx concentration emitted to the ground atmosphere mainly depends on the type of fuel burned in the industrial and heating boilers. Changes in the country's thermal policy and requirements that are set for us by the European Union States are forcing us to reduce greenhouse gas emissions. Directed metered ballast method is one of the most attractive techniques for reducing NOx emissions. In recent years, moisture injection technology is still investigated on low and medium power thermal power boilers operating on gaseous fuel. The goal of this work was to perform the investigations of the process of a moisture injection into the zones of decisive influence (SDW-I and SDW-II) on steam and water boilers: DKVR 10-13, DKVR 20-13, DE 25-14 and PTVM-50. The obtained results clearly show how the proposed method affects NOx reduction and boiler efficiency.

Abstract International maritime shipping—powered by heavy fuel oil—contributes 2.5%, 12%, and 13% of global anthropogenic CO2, SO2, and NOx emissions, respectively. The direct electrification of vessels has been underexplored as a low-emission option despite its considerable efficiency advantage over electrofuels such as green hydrogen and ammonia. Previous studies of ship electrification have relied on outdated battery cost and energy density values and have incorrectly assumed mechanical space to be a fixed technical variable. We show that with near-future battery prices of $100 kWh-1 the electrification of intraregional trade routes of less than 1,000 km is economically feasible with minimal impact to ship carrying capacity. Projected declines in battery price to $50 kWh-1 could improve this range to 5,000 km. We describe a pathway for the battery electrification of containerships within this decade that electrifies over 40% of global containership traffic, reduces CO2 emissions by 40% for US-based vessels, and mitigates the health impacts of air pollution on coastal communities.

The difficulties of burning the watered fuel oil used at the TPP as a reserve fuel for boilers are associated with its preparation by heating to reduce viscosity and the choice of a method of spraying with nozzles into the combustion zone. The quality of the preparation of fuel oil for combustion affecting the boiler efficiency is estimated by the length of the flame, the presence of burning large particles of fuel oil, the injection of coke and unburned particles onto screen and other heat-receiving surfaces. One of the ways to prepare fuel oil for combustion is cavitation treatment, which results in an emulsion consisting of fine micronsized particles. Heating of fuel oil particles after the nozzle in contact with the combustion zone is due to the flow of radiation from the burning torch. Therefore, in this article, the values of the flux density from the torch during the combustion of fuel oil are experimentally determined. The influence of particle size on the burning rate of the fuel oil M100 with the different density of the thermal radiation of the flame. It is found that the effect of cavitation treatment of fuel oil on the combustion rate is most significantly manifested in particle sizes less than 10 microns. For this purpose, the use of hydrodynamic cavitators are preferred at high fuel oil consumption rate.

An analysis of Ukraine’s sustainable development targets, in particular in the field of energy, resource management and environmental protection, are presented. It is shown that regional energetic is a determining factor for achieving the aims of sustainable development. Changes in the natural environment in Ukraine due to external (global) and internal (local) factors that are intertwined and overlapped can cause threats to socio-economic development. It is proved that in the areas of mining and industrial activity a multiple increase in emissions of pollutants into the environment are observed. The comparison confirmed the overall compliance of the structure of consumption of primary energy resources (solid fossil fuels, natural gas, nuclear fuel, oil and petroleum products, renewable energy sources) in Ukraine and in the European Union, shows a steaby trend to reduce the share of solid fuels and natural gas and increasing the shares of energy from renewable sources. For example, in Ukraine the shares in the production and cost of electricity in 2018 was: the nuclear power plants – 54.33 % and in the cost – 26.60 %, the thermal power – 35.95 and 59.52 %, the renewable energy sources – 9.6 and 13.88 %. The energy component must be given priority, as it is crucial for achieving of all other goals of sustainable development and harmonization of socio-economic progress. The paper systematizes the indicators of regional energy efficiency and proposes a dynamic model for the transition to sustainable energy development of the region.
