Ferrous metallurgy is a colossal industry with huge number of industrial facilities and equipment built for centuries. It accounts approximately 8 % current global anthropogenic emissions CO 2 oxides. The future decarbonization these assets depends on investments by major market players in the development implementation breakthrough steel production technologies operation carbon units market. With careful responsible management companies’ climate agenda, even against backdrop ever-growing...

The paper presents the developed fiber-optic sensors for monitoring pressure measurement on elements of mine supports. sudden destruction support leads to collapse workings and poses a serious threat life safety underground workers. A system changes in pressures supports will increase share mining automation reduce manual labor, as well eliminate errors associated with human factor. Systematic state working allow timely tracking their deformations caused by an rock them. Implementation at...

The article describes a method of integrating small distributed generation components in the power system Republic Vietnam. features energy Vietnam and technologies used for mini thermal plants are considered. classification is presented with implantation most resources Vietnam—fossil renewable. A generalized methodology selection calculation technological schemes steam-turbine operating coal gas-turbine solar air heaters selected. Based on selected plant schemes, their distribution...

The creation of efficient and compact heat exchangers is one the priority tasks arising during design gas supply to industrial residential buildings. As a rule, finned surfaces turbulization carrier flows are used increase efficiency exchange in exchangers. present paper proposes use novel materials, namely porous material, highly investigation was carried out experimentally theoretically. To study possibility creating such exchangers, multi-purpose test bench created. aim assess intensity...

RELEVANCE. Agricultural enterprises generate vegetable waste, which is difficult to utilize. Such waste can be used for combustion in boilers, providing thermal and electric energy an agricultural complex. A hybrid mini-thermal power plant combining renewable sources biofuels will able provide more economical, environmentally friendly reliable supplies of heat electricity under any demand conditions compared using one these systems. OBJECTIVE. Determination fuel consumption during various...

Introduction. Installations for thermal energy storage make it possible to smooth peak loads and provide stability of heat power system. These solutions are particular relevance private households. The purpose this paper is analyze the feasibility using a accumulator based on talc-magnesite with aerogel insulation. Materials methods. In order determine temperature insulation surface visualize profile, simulation in ANSYS software package was carried out. Autodesk Inventor selected as an...

This article discusses how a steam screw-rotor machine (SSRM) can be introduced as an energy-saving measure at chemical plants.The difference between SSRM and traditional blade turbine installations is also shown.It proposed that SSRMs into the thermal circuits of plants in parallel with existing pressure reduction desuperheating station (PRDS) 30/16 PRDS 15/8 to make it possible use potential energy steam.Passing through SSRM, decreases its required parameters then directed technological...

In the article an overview of main direction complex use ash and slag waste from coal-fired stations was provided. The composition waste, methods isolation valuable components key areas their further using were noted. results analysis residual carbon, nitrogen mineral part Kirov Moscow dumps Kazanskaya heat power station - 2 shown perspective directions utilization determined.

This paper investigates fibrous thermal insulation materials of various densities to assess the change in their thermophysical properties at high temperatures. The conductivity is discussed as a function temperature range from 50 °C 500 °C. It shown that insulating depend not only on physical material (e.g., density or diameter fibres), but also geometric parameters structure and orientation fibres. influence temperatures mass associated with burnout synthetic binders shown. These features...

The growing demand for energy and fossil fuels creates increased number of difficulties, while renewable sources are still rarely used worldwide, particularly in Vietnam. In this article hybrid thermal power plants based on gas turbine discussed, the efficiency which is achieved by air heating after compressor solar heaters. basic design equations results evaluating fuel consumption presented two 4.6 MW 11.8 MW. dependence intensity extraction climatic conditions Ninh Thuan province Republic...
