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 ...

Performance of externally fired combined cycle (EFCC)
The externally fired combined cycle (EFCC) which utilises coal as the primary fuel through a gas turbine cycle is a clean coal technology. Natural gas is used as the supplementary fuel, but the ultimate goal of the EFCC concept is a coal only option. In this study, the performance of the EFCC plant is evaluated based on the first and the second laws of thermodynamics, considering various levels ...

The use of wire mesh reactors to characterise solid fuels and provide improved understanding of larger scale thermochemical processes
Most reaction products from the pyrolysis and the early stages of gasification of solid fuels are chemically reactive. Secondary reactions between primary products and with heated fuel particles tend to affect the final product distributions. The extents and pathways of these secondary reactions are determined mostly by the heating rate and the size and shape of the reaction zone and of the ...

Vattenfall`s Cogeneration Power Plant Reuter West - Case Study
The cogeneration power plant “Reuter West” was erected as a base load power plant in the vicinity of the existing “Reuter” plant. The two hard coal fired 300 MW units D and E were commissioned in 1987 and 1989. Today the cogeneration units supplying electricity and thermal energy are operated by Vattenfall Europe GmbH. The heart of each power plant is the boiler where the ...

How fire can be tamed
Combustion dies at the interface between breathable air and macroscopic pieces of certain involatile fuels. If fed only them, in a compressed oxygen chamber, it makes an almost sunlike flame that cannot run wild. If upon dilution to manageable coolness the ash drops to the chamber bottom, and from there can be removed without the diluent, true harnessbrokenness is possible. Excess oxygen can be ...

Characterization of black carbon-containing fine particles in Beijing during wintertime
Abstract. Refractory black carbon (BC) is a product of incomplete combustion of fossil fuel, biomass and biofuel. etc. By mixing with other species. BC can play significant roles in climate change, visibility impairment and human health. Such BC-containing particles in densely populated megac-ities like Beijing may have specific sources and properties that are important to haze formation and air ...

Reasons to buy Household Diesel Generators
During an emergency, it is very likely that your home could lose power. This is why more and more people are buying household diesel generators to ensure their family and loved ones have power when it is most critically needed. During the hurricane season of 2017, a large portion of Americans learned the importance of owning a diesel power generator when electricity was lost for several days and ...

Developments in Auxiliary Power for Vehicles
Fuel cells are widely recognised as a technology of the future and as a potential replacement for the internal combustion engine in cars and other vehicles.This article looks at the potential for fuel cells to provide auxiliary power to vehicles, rather than primary motive power. Today, hydrogen-fuelled proton exchange membrane (PEM) type fuel cells, as illustrated in Figure 1, are ...

Consumption analysis of Solid Oxide Fuel Cells
The characteristics of the Solid Oxide Fuel Cell (SOFC) were introduced. The SOFC system can be divided into ten sections based on the Second Law of Thermodynamics. The fuel specific consumption was taken as the primary indicator to investigate the specific consumption for each section. The Energy-flow Framework Diagram (EFD) was undertaken to modify the system, such as controlling the operating ...

Much light, little heat efficiency
Energy efficiency in the US is much light and little heat – literally. Government policy pays a great deal of attention to saving electricity, but focuses little on the thermal energy we waste. “Policy is electricity-centric in the US. Unless you are making kilowatts, the most efficient investments are off the radar,” said Rob Thornton, president of the International District ...
