>Assessing and managing spontaneous combustion of coal
Chapter 2 briefly summarises the causes of spontaneous combustion in coal. Chapter 3 looks at evaluating the changes in coal the release of gases and increase in temperature – which can be used – to monitor potential incidents of self-heating and, ideally, through the application of quick respoprevent nses, combustion events.
>Emissions from Coal Fires and Their Impact on the Environment
fire through the soil over the area of an underground coal fire (diffuse emissions). When combined, the vent and diffuse emis-sions give an estimate of the daily amount of CO. 2. released by the coal fire. Vent emissions are also measured for gaseous CO, CH. 4, hydrogen sulfide, and Hg. The ground-based approach was initially applied in a study

>Black Smoke: What Does It Mean And What Causes It?
In coal fire, for example, the smoke particles are what we might think of as "ash". It depends on the fire and the product being burned and how well it is being burned as to what kind of smoke may be produced. Thus, smoke tends to be made up of tiny particles of either partially oxidized or fully oxidized or unreacted fuel particles.

>Coal Fires a major Source of Greenhouse Gases- a …
The main reason of the spontaneous self-ignition of coal is unscientific or illegal mining. Due to the character of the coal the fires start in areas were coal comes in contact with oxygen. These coal fires are caused anthropogenic and emerge from crude mining activities.
>Hazard Alert: Combustible Dust Explosions
In addition to the familiar fire triangle of oxygen, heat, and fuel (the dust), dispersion of dust particles in sufficient quantity and concentration can cause rapid combustion known as a deflagration. If the event is confined by an enclosure such as a building, room, vessel, or process equipment, the resulting pressure rise may cause an explosion.
