… in relation to the time of initial flame exposure and propensity for continued combustion of standing CWD of pine (Pinus sylvestris). Two types of CWD were studied. Firstly, wood that had been dead for one to ten years. Secondly, wood that had been dead for several decades. In …
… low particulates and high efficiency. Due to its homogeneous charge, where the combustion starts almost simultaneously from a number of points in the combustion chamber, only lean mixtures are possible to burn because of the resulting rapid combustion, which is much faster than …

… to be explosive and flammable. These properties are both good and bad for combustion. The purpose of this study is to present the problems and solutions that concern hydrogen as a fuel both inside and outside the combustion engine. The most common method of production is steam …
Combustion of fossil fuels is today the dominating source of energy. During combustion,carbon dioxide is formed. The carbon dioxide accumulates in the atmosphere,which raises the global average temperature on earth through the so called greenhouseeffect. The only way to reduce …
EL-KONVERTERING AV INOMBORDSMOTORER TILL SEGELBÅTAR
… it is vital to find alternative environmental-friendly motors and replace combustion-engines. Zilent Ocean is an extensive project within Development engineering program at Halmstad University. The Project aims at minimizing environmental impact on our seas through limiting the …
… with the numerical 3D simulation of a four stroke, spark-ignited, internal combustion engine, which is mounted on a high performance motorcycle. The work, carried out in collaboration with Politecnico di Milano and MV Agusta, focuses on the simulation of the intake, compression …
… steadily, and 46 percent of the municipal solid waste (MSW) is treated by combustion. This report aims to examine the profitability of processing MSW into Refuse Derived Fuel (RDF) from an economic-, energy- and environmental perspective. In order to obtain a comparison with …
… and environment friendly way. This report focuses on waste fractions meant for combustion, often difficult to characterize. However, more homogeneous fractions that are treated biologically are also discussed. The study concerns the region of Borås, Sweden, where the waste plant …

… in Sweden have increased with 60% since the 1970's. Different fuels affects combustion and the release of various substances and particles into the flue gas. This is caused by the diverse components and chemical structures of fossil fuels and bio fuels. When the flue gas leave …
To achieve an optimal combustion, an even air/fuel ratio in the combustion chamber is required. An optimal combustion leads to reduced amount of emissions due to a more complete combustion, which is an important matter because of the sharpened environmental laws. This can be …
Teoretisk analys och praktisk försök
… describes a completely new biofuel system to generate particle-free heat from combustion of ash-containing biofuel particles at high temperatures. The suggested system gives opportunities to introduce biofuels in new areas. Main components in the suggested system is a heat …
In this report focus is put on the combustion process at a cement plant. Combustion is the heart of the cement making process and absolutely crucial to have under full control and well optimized. The fuel is put into the process through a burner pipe and this burner pipe is …

… heat and electricity in Europe today is by the incineration of waste or combustion of coal. These materials can be very sulfurous and during combustion sulfur dioxide is produced. This is an environmental and health related toxic substance which is why power plants have strict …
The purpose of this thesis was to develop and optimize a method of analysis for combustion of organic chemical products, followed by an ion chromatographic quantitative analysis. This was to be achieved with the decomposition equipment IKA AOD 1. The aim was to receive a precise …
… energy demand is supplied by fossil fuels. Improving energy efficiency in combustion engines will result in reduction of fuel consumption and CO2 emissions. A modern internal combustion engine has an efficiency of 30-45 %, where the most energy loss occurs as result of heat …
