The effects of coal dust concentrations and particle sizes on the minimum auto‐ignition temperature of a coal dust cloud

Fire and Materials, 2017
SummaryFlash fires and explosions in areas containing an enriched combustible dust atmosphere are a major safety concern in industrial processing. An experimental study was conducted to analyse the effects of atmospheric coal dust particle sizes and concentrations on the minimum auto‐ignition temperature (MAIT) of a dust cloud.

Dust concentrations around coal stockpiles

Science of The Total Environment, 1980
Abstract One of the sources of airborne dust from operations at coal terminals is wind erosion of the stockpiles. The condition of the stockpile, whether it is being worked (a live stockpile) or at rest (dead storage), is of prime importance. A further important set of variables is formed by the meteorological conditions.

Effect of Coal Mine Health and Safety Act on Respirable Dust Concentrations in Coal Mines

American Industrial Hygiene Association Journal, 1972
Under the Federal Coal Mine Health and Safety Act of 1969 the operators of coal mines are required (effective June 30, 1970) to maintain the average concentration of respirahle dust in active workings at or helow 3.0 mg/m.3 The standard is reduced to 2.0 mg/m3 after December 30, 1972.

Prediction of Respirable Dust Concentration in Coal Mine Based on Neural Network

2020 IEEE Conference on Telecommunications, Optics and Computer Science (TOCS), 2020
Pneumoconiosis is the most important occupational disease in China, and respiratory respirable dust is the main cause of pneumoconiosis. It can effectively reduce the incidence of pneumoconiosis by improving the monitoring and supervision level of respiratory dust concentration in the workplace.

Concentrations of atmospheric SO2, NO2 and dust in the lublin coal basin area

Science of The Total Environment, 1990
Abstract This paper presents concentrations of SO 2 , NO 2 and total suspended particulates (TSP) in the atmosphere as well as the quantity of dustfall. Air samples were collected periodically over a 1-year period at eight monitoring stations situated in an area of 8 × 8 km 2 , located in the Central Coal Region area of the Lublin Coal Basin.

High Dust Concentration ESP for Coal-fired Boiler of 300 MW Generator

2009
In the dry Flue Gas Desulphurization(FGD) system, ESP plays an important role; one of its outstanding characteristics is that it can treat with high dust concentration flue gas. Compared with conventional ESP equipped for coal-fired boilers, the successful application of this kind of ESP is a great breakthrough.
