Quantifying Burning, Heat Transfer, and Material Ignition of Smoldering Firebrand Piles
… ignition resistance reliability exposed to a smoldering firebrand pile. The exposure was based on empirical relations for the heat flux from piles as a function of pile height, porosity, and wind speed. Cone calorimeter data was used to generate material thermal and ignition properties. With …

Finite-Difference Modeling of the Batch Process Smoldering Combustion of Wastewater
<p>A MATLAB model was developed for the smoldering combustion of wastewater in the context of a decentralized residential wastewater treatment appliance. Data from a batch process sewage smoldering experiment was simulated using implicit finite-difference approximations, assuming one-dimensional …

Drivers and Impacts of Smoldering Peat Fires in the Great Dismal Swamp
… to understand both the drivers and impacts of smoldering fires at the Great Dismal Swamp (VA and NC, USA). First, we developed and verified a new method to model peat burn depths with readily available water level and peat hydraulic property data. Our findings suggest that drainage weakens both …

A Self-Potential for Monitoring Self-Sustaining Treatment for Active Remediation (STAR)
… in a porous medium. STAR is based on liquid smoldering combustion which destroys NAPLs while simultaneously generating heat due to the exothermic oxidation reaction. The technique is currently in use in several field pilot tests and a full-scale site remediation. Propagation of the smoldering …

Parameterizing Climate-Relevant Properties of Biofuel and Biomass Particulate Emissions Based on Combustion Conditions
… mixed with a larger mass fraction of hygroscopic smoldering emissions; however the mixture's growth was less than the growth of pure smoldering emissions. The optical properties of the mixture were dominated by the soot.

Spontaneous Ignition of Linseed Oil Soaked Cotton Using the Oven Basket and Crossing Point Methods
… reached three different stages; ignition, smoldering or constant smoldering and flaming. The activation energies were 42.37 kJ/mol, 27.40 kJ/mol, 16.97 kJ/mol, 15.76 kJ/mol and 11.73 kJ/mol for the 5cm (33.3%), 5cm (50%), 7.5% (77%) and 10cm (80%) basket sizes. It was concluded that as the …

Characteristics of Household Solid Waste Open Burning Emissions
… Uncontrolled, low temperature burning, and smoldering conditions are typical associated with household waste fires. Emissions from these ground level burns cause local and regional air pollution, leading to adverse health effects among community residents. It is known that emissions from …

Characteristics of pine needle combustion in a semi-gasifier burner
… pine needles, and another characterized by the smoldering of pine needle charcoal. Each regime needed unique balances between primary air and secondary airflow. The first regime required a relatively low primary airflow with a high secondary airflow, while the second regime needed a high primary …
