Smoke Emissions from Wildland Fires
Biomass burning is a major source of emissions to the atmosphere. Some of these emissions may change global climate. This paper uses combustion eff iciency as an independent variable for predicting emission factors for, among others, carbon monoxide, carbon dioxide, methane, and particulate matter. Other gases are correlated with the release of carbon monoxide. The release of nitrogen and sulfu...
متن کاملLightning response to smoke from Amazonian fires
[1] The effect of anthropogenic aerosols on clouds has the potential to be a key component for climate change predictions, yet is one of the least understood. It is possible that high aerosol loading can change the convection intensity and hence the electrical activity of thunderstorm clouds. Focusing on the Amazon dry season, where thousands of man‐made forest fires inject smoke into the atmos...
متن کاملSimulation of Smoke Emission from Fires in High-Rise Buildings Using the 3D Model Generated from 2-Dimensional Cadastral Data
Having a 3-Dimensional model of high-rise buildings can be used in disaster management such as fire cases to reduce casualties. The fundamental dilemma in 3D building modeling is the unavailability of suitable data sources. However, available cadastral 2D maps could be used as low-cost and attainable resources for 3D building modeling. Smoke will be a great threat to people's health during a f...
متن کاملMercury emissions from biomass burning in China.
Biomass burning covers open fires (forest and grassland fires, crop residue burning in fields, etc.) and biofuel combustion (crop residues and wood, etc., used as fuel). As a large agricultural country, China may produce large quantities of mercury emissions from biomass burning. A new mercury emission inventory in China is needed because previous studies reflected outdated biomass burning with...
متن کاملEvaluating the Smoke Hazard from Fires in Large Spaces
Current codes in many countries require that the smoke layer be maintained a particular distance above the highest walking surface in an atrium. The smoke exhaust capacity to accomplish the required performance can be extraordinary, especially in a tall atrium with the upper floors open to the atrium. The effect of exposure to smoke is a function of the magnitude of the smoke signature, e.g. co...
