... Abstract The present study aims to evaluate the intrinsic differences in in-cylinder combustion in low load and low-speed conditions by applying experimental and numerical techniques. The experimental apparatus consisted of an AVL5406 SI-PFI single-cylinder with optical access operating under...

... Abstract During the combustion of solid biomass in a grate-fired boiler, each particle experiences a sequence of processes which include heating, drying, devolatilization, and char combustion. Furthermore, in the gas phase, products may react with oxygen. As it is impossible to maintain...

... Abstract The most energy intensive part of a hot rolling mill is the reheat furnace, where the steel products, the products are heated to target temperature using the combustion of natural gas. The energy consumption of the reheat furnace in a typical integrated steel mill is the second highest...

... Abstract In the last two decades, the interest in the use of solid biomass as a fuel for power generation, together with the continuous tightening of regulations, has motivated the improvement of accurate design techniques which are required to optimize the combustion process, new technologies...

... cells (SOFCs) and their need for high operation temperatures, combustion systems become obvious targets for integration. The fuel-rich combustion of natural gas can produce synthesis gas, while providing the heat necessary for SOFC operation. To remedy issues associated with degradation of cell...

... Abstract In many coal combustion simulations, only one mixture fraction is used to model the coal-off gases. This assumption, however, is not accurate because the coal char and coal volatiles have considerable differences in composition. In the case of a coal:manure blend combustion, the use...

... because of their easy of use, high efficiency and low emissions. The practical interest in pellet combustion has been driven by the domestic heating sector, which favors the characteristics that are intrinsic of this fuel, despite its relatively higher price. However, the growing costs of fossil fuels...

The study conveys that at higher compression ratio, POME causes reduction in brake fuel consumption and thereby increases the engine efficiency. The increase in compression ratio also causes smoother combustion, lower ignition delay...
