Abstract. Solid fuel (SF) combustions, including coal and biomass, are important sources of pollutants in the particle gas phase therefore have significant implications for air quality, climate, human health. In this study, we systematically examined gas-phase emissions, using Vocus proton-transfer-reaction time-of-flight (PTR-TOF) mass spectrometer, from a variety solid fuels, beech logs, spruce/pine branches needles, straw, cow dung, coal. The average emission factors (EFs) organic vapors...
With over 1.6 billion vehicles worldwide, the combustion of fossil fuels is a major source particulate matter (PM) and trace gases, which significantly contribute to air pollution, climate change cause health burden. Heavy-duty (HDVs) constitute small fraction global vehicle population but account for disproportionately large share total emissions when compared with light-duty (LDVs). However, uncertainty remains about type most emission factors (EFs) various pollutants, particularly in...
Volatile Methyl Siloxanes (VMSs) are anthropogenic molecules emitted from personal care products and industrial chemical products. Recent studies have found that concentrations of VMSs tend to be higher in densely populated urban areas, although research large centers remains limited. Toxicity such remain uncertain with often conflicting reports. Previous literature has also reported the presence long chain siloxanes particle phase traffic emissions, represented first identification...
Injection of solid tritium pellets is considered to be the most promising way fueling fusion reactors. The Tritium Proof-of-Principle experiment has demonstrated feasibility forming and accelerating pellets. This injector based on pneumatic pipe-gun concept, in which are formed situ barrel accelerated with high-pressure gas. ideal for service because there no moving parts inside gun excess required pellet production process. Removal 3He from prevent blocking cryopumping action by...
Plasma fueling via injection of solid hydrogenic pellets has expanded the operating range for tokamaks and stellarators to higher densities than attainable with gas puffing. Pellet also resulted in improved plasma energy confinement tokamak discharges which pellet or penetrate deep into core. The eight-shot pneumatic injector described herein been developed use on Princeton Beta Experiment Advanced Toroidal Facility routine optimization studies. is based upon so-called ‘‘pipe-gun’’ concept,...
