EU regulation of combustion plant - A power industry perspective
Any installation that contains combustion plant with an aggregated thermal input greater than 50 MW is regulated under the Industrial Emissions Directive (IED) which requires that Best Available Techniques are applied to emissions control. Individual plant with a thermal input greater than 50 MW are regarded as Large Combustion Plant and additional provisions apply, including mandatory Emission ...

UK Abattoir – Rotary incinerator - Case Study
Designed to process animal remains 24 hours/day, 7 days/week, with the minimum of operator attendance. To optimise the plant’s performance and to enable waste to be processed and stored, irrespective of the status of the combustion plant, the waste is crushed into 50mm cubes. The material is then conveyed into a buffer hopper, which stores sufficient material to enable the plant to be left ...

World Coal - Global Coal Power Review
All combustion plant operators are aware of the need to report emissions of particulate matter to environmental regulators, and opacity monitoring remains the preferred technique in much of North American and Asia. Although more sensitive techniques are available, opacity monitors have a number of features which make them especially attractive, including the ability to calibrate the analyser ...

Exergetic performance investigation of a turbocharged stationary diesel engine
An exergetic assessment is reported of a turbocharged stationary diesel engine with a power output of about 19 MW. The system studied consists of a diesel engine, a turbine, a compressor, an intercooler and a radiator. The sites of exergy destructions are identified and quantified and the exergy efficiencies of various components are determined. The effects of inlet air temperature and pressure ...

Kinetics of forming the nitrogen oxides and other harmful substances in catalytic power plants
In the following paper, the kinetics of forming nitrogen oxides and other harmful substances in catalytic power plants are described. First of all, the equilibrium NOx concentrations are considered. The discrepancy between equilibrium concentrations and real results on NOx in the case of flame combustion are explained by a short duration of fuel-air mixture stay in furnace space. The positive ...

Reducing air pollution from electricity-generating large combustion plants in the European Union
Background In 2008, the European Environment Agency (EEA) published a first assessment of the theoretical potential to reduce emissions of nitrogen oxides (NOX) and sulphur dioxide (SO2) from electricitygenerating large combustion plants (LCPs) (EEA, 2008). That earlier study showed that improving the environmental performance of existing LCPs by applying best available techniques potentially ...

Project - Bowling Green, Ohio Steam Plant - Cogeneration
Capacity: 240 kpph A University Steam Plant owns and operates three gas and fuel oil fired boilers at their powerhouse located in BowlingGreen, Ohio. The steam plant combusts natural gas as a primary fuel and utilizes #2 fuel oil as a supplementary fuel to generate steam for heating and cooking at the University. The three 80,000 pound per hour units are designated Units #1, #2, and #3. The ...

Energotechnological oil shale utilisation by means of an SHCU - a low waste and environmentally sound technological process
This paper presents the calculated data on the emissions into the environment from the low-waste energotechnological solid heat carrier units (SHCUs) working with oil shales. A comparison of this technology with direct oil shale combustion at a power plant was carried out using the example of an Estonian power plant. The energotechnological plant (ETP) including two units SHCU-3000 with an oil ...

The impacts of technological learning on the optimum technology mix: simulations for the Indian power sector
For the investigation of the optimum technology mix of any country, which is clearly an issue of dynamic nature, technological learning and economies of scale play a significant role. Hence, in this paper's long term planning exercise for the Indian power sector (2000-2025), our simulation analysis specifically includes the impacts of technological learning on the optimal inter-temporal choice of ...

Improving steam power plant efficiency through exergy analysis: effects of altering excess combustion air and stack-gas temperature
Modifications are examined to increase coal-fired steam power plant efficiency by reducing irreversibilities in the steam generator, including decreasing the fraction of excess combustion air, and/or the stack-gas temperature. Overall-plant energy and exergy efficiencies both increase by 1.4% when the fraction of excess combustion air decreases from 0.4 to 0.15, and by 3.5% when the stack-gas ...
