Mechanical densification is a process of transforming loose biomass into dense pellets. In this study, a wood pelleting plant was chosen to evaluate the total energy consumption, environmental emissions and cost of pellet production using different alternative fuels for the drying process. The fuels compared were natural gas, coal, dry and wet sawdust, and ground wood pellets. The process model...

The efficiency of pellet injection and the relationship between D/T fuel ratio and plasma parameters were analyzed numerically using the TOTAL (toroidal transport analysis linkage) simulation code, which consists of the equilibrium calculation code and a one-dimensional transport simulation model. The simulation which included scanning the pellet penetration depth and the pellet D/T ratio was p...

There is a growing concern that the velocity of the DT-ice pellets being proposed to fuel ITER will not have the velocity to effectively penetrate through the pedestal of the plasma edge, because with velocities of only 300 m/s, high field side launched pellets will only penetrate to € r /a = 0.90, which may not be adequate for fueling. The likelihood of increasing the pellet velocity is proble...

This thesis focuses on two main areas: methods for assessing regional supply potentials of reed canary grass (Phalaris arundinacea L.) (RCG); and process technology for the production of high-quality RCG pellets. Partial equilibrium modelling, incorporating a break-even price approach, was used to examine supply potentials for RCG in Västerbotten County, northern Sweden. A remote sensing method...

Co-combustion of biosolids with coal or other biomass fuel can play a significant role in combustion facilities for energy production and waste management policy context. This paper presents the results of an experimental study to investigate the use of biosolids for co-combustion with wood pellets in a wood pellet stove. Fuel property, gas emissions and stove efficiency are compared. In regard...

Among the factors influencing degradation of spent nuclear fuel cladding in interim dry storage, irradiation history and average burnup at discharge must be considered. In fact, due to pellet-cladding contact particularly affecting high fuels, inner surface becomes increasingly exposed damage caused by alpha decaying actinides present rim pellet. Moreover, low temperature conditions characteris...

This proposed design for a mini thermonuclear reactor uses a method based upon a series of important innovations. A cumulative explosion presses a capsule with nuclear fuel up to 100 thousands of atmospheres, the explosive electric generator heats the capsule/pellet up to 100 million degrees and a special capsule and a special cover which keeps these pressure and temperature in capsule up to 0....

The performance of a superconducting linear accelerator (SLA) system for pellet injection in fuel nuclear fusion reactors was investigated numerically. To this end, numerical code using the finite element method developed to analyze shielding current density and dynamic motion high-temperature thin film SLA system. computational results showed that applying an exponential electromagnet, signifi...
