Oil shales - a competitive fuel of thermal power generation with new technologies
We show that, in spite of the low heat of combustion of oil shales, use of them on the basis of a new thermal-processing technology that produces high-calorie products (shale tar and fuel gas) makes this type of fuel competitive for thermal power plants (TPPs) in comparison with high-calorie coals. When a certain amount of shale tar and all of the fuel gas are used in a combined cycle of a TPP, ...

Development of an energy efficient curtain flame ignition system for sintering of iron ore fines
Research and Development Centre for Iron and Steel (RDCIS) of Steel Authority of India Limited (SAIL) has developed a 'curtain flame' ignition system for sinter mix ignition. Conventionally, either horizontal fired burners or top fired or a combination of both are used for ignition of sinter mix. These burners big in size but few in number are mounted on a rectangular box type furnace. This is ...

Modelling industrial flares impacts
This document introduces a new software to estimate the atmospheric impact of industrial flares. The software allows to design stacks with correct height and diameter in order to minimise risks for workers and nearby structures. It also allows to estimate the thermal impact and acoustic impact of existing or future flares. Flame tilting due to the wind speed can be modelled with a simple ...

Catalytic boilers with catalytic fluidised bed
In this paper, conditions of work, special features and problems of boilers with catalytic fluidised bed are described. The specific conditions, when the catalyst layer remains stationary and granular or becomes spouting, are also considered. There are some main zones in the catalytic boilers with fluidised bed, which characterise such boilers and which must exist in them under normal working ...

Replacing of mechanical compressors by gas ejectors in flare gas recovery systems
One of the main concerns of humankind in this century is the global warming induced by the increasing concentration of greenhouse gases in the atmosphere. A promising process for controlling the atmospheric CO2 level is prevention of combustion in flares causing high losses of raw material and energy that could generate more desired products. In the present work, a flare gas recovery unit (FGRU) ...

Environmental pollution from the use of alternative fuels in a four-stroke engine
This paper discusses the use of the fuels propane and butane–propane (80:20) in a four-stroke engine made to function with gasoline (petrol). The experiment covered gas emissions, emissions temperature and fuel consumption. It was observed that gas emissions were reduced compared with gasoline. The reduction for carbon monoxide emissions was greater when butane–propane was used. The same was true ...

Project Tank Vapors - Case Study
Project Overview: In 2015 Questor was selected to provide emissions control for a truck loading and tank vapors at a Shell oil battery in Alberta, Canada. The waste gas stream consists primarily of rich gasses, ethane (~19 mol%), propane (~35 mol%), butane (~24 mol%) and remaining hydrocarbons, ~35 mscf/d of fuel gas is required to draw the low pressure waste gas stream into the thermal oxidizer ...

The influence of climate change considerations on energy policy: the case of Russia
To those working on climate change, it is obvious that energy policy should be influenced by climate change considerations. The question that this paper seeks to answer is, to what extent do they influence policy and what contribution can a careful analysis of the costs and benefits of climate change options have on the formulation of that policy? We seek to understand this by looking in some ...

Plasma resource recovery technology –converting waste to energy and valuable products
Abstract Plasma Resource Recovery (PRR) is a revolutionary technology that can treat virtually any type of waste by combining gasification with vitrification. Vitrification produces inert slag that can be used as a construction material. Gasification produces a fuel gas containing carbon monoxide (CO) and hydrogen (H2), used for cogeneration of electricity and steam. The plasma fired eductor ...

Method of producing power-generation and engine fuels from oil shale fines with solid heat carrier units (SHCU)
The technical feasibility and economic expediency of the shale-converting power technology complex at the Leningradskoye deposit in northwest Russia is substantiated herein. Two basic options of production utilisation are considered: manufacture of power fluid fuels, mainly for gas turbines and combined-cycle units; and production of boiler and ship fuel oils and domestic gas fuels.Keywords: ...

Practical guide to alternative fuel utilisation
Today’s business environment for the cement producers is becoming more challenging. Rising production costs and environmental regulations are only two of the main limiting factors. Therefore the cement industry is using alternative fuels. In most cement kiln processes today, the conventional fuels (primary fuels) are gas, fuel oil, various coals and petcoke. The required calorific values can be ...

CHP efficiency for biogas
Combined heat and power plant efficiency is a function of the conversion efficiency of the energy in the fuel gas to useful energy in the form of electricity and heat. A combined heat and power (CHP) plant is typically a reciprocating gas engine that uses the energy in the gas to drive a crank shaft. The crank shaft turns an alternator to produce electricity. Heat is released during the gas ...

Evaluating technologies in automobile markets
A new approach has been developed for the comprehensive comparison of competing technologies. It combines two well-established tools: life-cycle assessment (LCA) and energy-engineering models (EEM). The approach has been applied to evaluate different car powertrains and fuels. The results show how the ranking of different technologies depends on assumptions and the value system of the ...

The viessmann domestic fuel cell energy centre in its trial phase
As far as mass production is concerned, the domestic fuel cell energy centre represents an equipment without much history. The reversible and irreversible influences on its function and the service life of the equipment are not yet not fully understood; in particular the decrease in the effectiveness of the catalysts poses a real challenge. The service life required for detached and two-family ...

Problems of catalytic boiler safety and their role in designing and operation of gas-fired boiler
In the following paper, some problems of safety for catalytic boilers with fixed and fluidised beds are discussed. The reason is to protect the boiler from gas and fuel-air mixture explosion. For it the conditions excluding the transition from catalytic combustion to flame must be observed, and they are presented in the article for different combustible gases. A special attention has been paid to ...

Case study - Agiba Gas Power Generation
Proserve has recently carried out a power generation project with Agiba Petroleum Company in the western desert of Egypt to utilize the waste free flare gas instead of the very expensive fossil diesel fuel to power the oil production wells ‘pumps. The project faced several technical challenges. The associated gas has a low methane number” less than 45”, which necessitated a ...

World’s Fastest Compressed Natural Gas Car - Case Study
Fueled by Clean Air Power gas injectors, the Lessman Streamliner proved to be the world’s fastest natural gas vehicle when it hit an official speed of 370 mph at the Bonneville Salt Flat in September 2018. Lessman is motivated to demonstrate the performance of green fuel technology with the new goal of 400mph set as the target for 2021. With an official timed speed by the Southern ...

Desulfurization and reduction of siloxanes in biogas
Reducing the carbon footprint of our society is essential. This can be achieved by capturing and confining anthropogenic CO2 emissions, as well as by replacing fossil fuels with renewable fuels. MCFCs (Molten Carbonate Fuel Cells) are the only ones capable of doing both. Thanks to their principle of operation, CO2 can be extracted from a gas stream on the cathode side and fuels such as biogas ...
