Exchangers are thoroughly used equipment for heat transfer. These equipment play a climacteric role in variegated business administration and buildings by providing heat exchange between two fluids. However, over time, exchangers can be subject to variegated problems such as contamination and sediment build-up. This can diminish heat transfer efficiency, leading to energy waste and equipment malfunctions. Calcification is a problem that comes off when water becomes saturated with hard minerals and exceeds the solubility of these minerals. These... minerals precipitate as a consequence of water evaporation or chemical reactions and form a solid layer called limestone. Limescale can bring variegated problems in homes, business administration, and water transportation systems. Lime accumulates on heat transfer superficies, reducing the superficies area of ​​these superficies. This reduces the superficies area available for heat transfer and inhibits heat transfer. The thermal conductivity of lime is lower than water. Scale, which is the formation of a scale layer on heat transfer superficies, reduces the thermal conductivity of these superficies and prevents heat transfer. This study focuses on the types of contamination in heat exchangers, the effect of contamination on heat transfer and other factors, and methods of clogging.Read more

Over the past decades, interest in renewable energy has grown, this is due to the aggravation of climate change. The emerging trend of decarbonization of the world economy, including transport and energy, which are one of the main sources of air pollution with carbon dioxide emissions. The article discusses issues of climate change, decarbonization scenario, a road map for “greening” the economy, and presents a brief analysis of trends in the development of hydrogen energy and the importance of the development of “green”... hydrogen in the world and in Turkmenistan. The main attention is paid to the prospects and scale of development of hydrogen energy to a certain extent will depend on the characteristics of the hydrogen sources proposed for use ­, primary energy sources and hydrogen production technologies, environmental consequences when using different approaches to hydrogen production, expected costs for hydrogen production, potential consumers and volumes of hydrogen consumption within the country and abroad, technologies for storing and delivering hydrogen to consumers, the competitiveness of hydrogen as an energy carrier in the domestic and foreign markets, taking into account all the necessary costs and a potential “transboundary carbon ­tax”.Read more

Many countries have used various strategies in the effort toward transition to alternative energy as a solution in developing renewable energy. Indonesia is the second largest producer of geothermal energy in the world. The potential of Indonesia lies in the Ring of Fire along with 117 active volcanoes, giving Indonesia high geothermal potential. This research aims to reveal and formulate the potential of geothermal as renewable energy in Indonesia as an alternative energy to be used in the future. The methods in this research are qualitative a...nd quantitative. Through the quantitative method, this research will present secondary data from various organizations as well as data from prior research on geothermal potential in the world. While qualitative method will formulate ideas of several geothermal usages from many countries by using comparison from prior research and literature from journals, books, and other publication sources. Qualitative research results will also come from in-depth interviews with stakeholders that have implemented geothermal energy in Indonesia. The result of this research will illustrate the importance of geothermal energy as an alternative renewable energy in Indonesia to replace crude oil resources as the main natural resource in Indonesia. This research recommends the mapping of resources, requiring technology as a breakthrough in processing geothermal energy to take it directly from the reservoir because of its unorthodox classification based on its source as well the cost and benefit impact on the economy related to consumer mapping to detect early the market changes of energy to geothermal.Read more

Sri Lanka is facing an energy crisis due to insufficient exploitation of renewable energy resources and high reliance on imported fossil fuels. Building-integrated PV (BIPV) systems are one approach that provides various benefits in countries with limited land areas and congested metropolitan regions for ensuring energy security. This study was conducted to evaluate the rooftop solar PV capacity and yearly electricity generation potential in selected provinces in Sri Lanka. The study found 115 km2 of rooftop area for solar PV installation in fo...ur Sri Lankan provinces; Sabaragamuwa, Western, Northern, and North Central with approximately 25 GW of solar PV installation capacity could lead to annual electricity generation of 45 TWh which could reduce carbon emissions by 20 million tCO2 per year.Read more

The purpose of this article is to propose a model of an electric-fired brick oven, with the aim of eliminating the imperfections presented by traditional brick ovens. To complete this study, we used the concepts of heat transfer, and material resistance, as well as those of computer-aided mechanical design.Deemed satisfactory, the results found give a yield of 94.5% and a cooking time of 7.29 hours based on 2000 bricks cooked.

The article examines the priorities and prospects of the road map for the development of renewable energy using the example of Turkmenistan. The main scientific conditions of the goal, objectives, principles of public policy, a heterogeneous class of renewable technologies, the main scientific conditions of the road map for sustainable development, the environmental aspect of climate change, mitigation potential, and costs are presented. The compiled roadmap for the use of renewable energy sources outlines the expected energy, economic, and env...ironmental effects from the use of renewable energy technologies in remote areas from the centralized power line. The author believes that the outlined development roadmap for the use of renewable energy sources will become the basis for drawing up programs in other countries, depending on natural, climatic, and geographical conditions. Thus, the road map for the development of renewable energy sources, the use of local renewable energy resources, can reduce the need for fossil fuels in some cases by up to 80% and will significantly reduce the anthropogenic load on the environment. The introduction of renewable energy sources is one of the most relevant and promising for the development of the desert and the fight against desertification in the Karakum.Read more

The article obtained systematized, scientifically substantiated gross, technical, economic, and environmental energy resource potentials from the introduction and use of solar energy technologies. The technical, economic, and environmental priorities of power plants were assessed in terms of energy efficiency, fuel economy, and the environmental impact per square meter from conversion to thermal and electrical energy in the city of Arkadag.The calculated results are, kWh/m2 per year: gross resource potential of solar energy - 1844.6; the techni...cal potential for conversion into thermal and electrical energy is equal to - 1256.44 and 242.44; economic - 502.6 and 96.98 kg fuel equivalent/m2 per year; environmental reduction in emissions of various harmful substances into the environment when using solar photovoltaic modules in the city of Arkadag will be: with annual electricity generation per m2 - 242.44 kW⋅h, annual fuel consumption savings - 96.96 kg. e., the reduction in emissions will be, kg per year: SO2 – 2.0; NOx – 1.1; CO – 0.14; CH4 – 0.29; CO2 – 155.0; solids – 0.21; when converted into thermal energy per m2 and annual production of 1256.4 kW⋅h, annual fuel savings are 502.6 kg of fuel equivalent; emission reduction will be, kg per year: SO2 – 10.4; NOx – 5.6; CO – 0.73; CH4 – 1.53; CO2 – 803.5; solids – 1.1.Empirical equations (1-5) have been obtained taking into account the gross, technical, economic, and environmental resource potentials of solar energy in the city of Arkadag, it is possible to carry out energy and environmental forecasting when drawing up a feasibility study.Read more
