Combustion of wood pellets with a high amount of fines

A comprehensive study of the efficiency of the 1.5 MW Arimax Bio Energy hot water boiler operating on wood pellets with a high amount of fines has been carried out. Fuel characteristics and its compliance with the quality requirements of Russian and European standards have been investigated. The components of the heat balance and emission of harmful substances have been determined. Thermovision study of the boiler was carried out. The comprehensive study showed that the boiler provides sufficiently high technical and economic performance and minimal emissions of nitrogen oxides and carbon monoxide. However, the high amount of fines in the pellets significantly increases the emissions of particulate matter and especially black carbon into the environment.

Identifying The Quantity of Combustion Heat when Briquetting Oil Waste Process

During the works by calculation, there were grounded the makeup of fuel briquettes, which are produced from oil wastes, coal and biomass - rice husk. Within changing considered makeups and concentration, combustion heat values calculated, which in future will allow to compare the experimental values of the fuel characteristics of the briquettes with an assigned structural composition

Investigation of 1-Hexanol Diesel Blends on Performance, Combustion and Emission Characteristics of a Diesel Engine

The most potential long-term and renewable substitute of mineral diesel are biofuels. The growth and degradation of energy resources have an enormous influence on the long-term viability of the human community. Alcohols are gaining prominence in the current renewable energy scenario due to their ease of manufacturing and fuel characteristics. In this investigation, hexanol-diesel blend ratios (up to 20% v/v) is taken into account for this investigation in a single cylinder, water cooled, unmodified 4-stroke DI diesel engine. The increase in 1-hexanol volume content correlates to an improvement in combustion thereby promoting brake thermal efficiency. The greater concentration of oxygen in 1-hexanol reduces emission viz. HC and CO and increases value of NOx. Current investigation recommends a feasible option to substitute ULSD for the capabilities of 1-hexanol.
