What Are Differences Among Gasification, Thermal Degradation And Smouldering?

Combustion Reaction: A chemical reaction between a fuel and an oxidizing agent that produces heat.

Not all combustion reactions involve organic compounds made of carbon and hydrogen (nonorganic compounds), which means that the products are not always

The most common source of heat for the purpose of firefighting comes from chemical reactions. When something burns, it is the result of a chemical reaction where heat is being released. Pyrolysis is the "decomposition or transformation of a compound caused by heat."(Coleman, et al. 81)

In the incipient stage heat and oxygen are combined and ignite creating the fire and initial point of fire. The growth stage there are several factors that can determine who large a fire becomes such as if there are any highly flammable items or combustibles in the area and the height of the ceiling creating thermal layering. Once a fire has reached its maximum potential it is now in the fully developed stage and is extremely hot and dangerous at that point. Decay occurs in a fire while it is being tamed or extinguished. The decay stage can be dangerous because if there are items that can cause a combustion that have not been ignited yet it can make a firefighter think they are out of the woods and safe and then a backdraft occurs because of the oxygen being reintroduced to the

Coal is created by plants that died and fell to the ground, then this plant matter is waterlogged by rainfall by things like sediment and other plant matter compressing it until over time it is compressed into a carbon rich rock that burns easily known as coal. Like any fire, coal will only burn if it has a constant supply of three things; fuel, heat, and oxygen. The best way to put out any fire is to deprive it of one of those to things, the easiest being heat or oxygen, problem is coal can burn in an environment with as little as 1% or 2% oxygen and the air that we breathe has about 21% oxygen and pre-existing cracks in rocks permit airflow straight to the fire.(Palus) (Perkins) The second option is to smother the flames and deprive the fire of its heat source, but the fire was

Burns occur when cells are subjected to high temperatures which lead to necrosis of the cell because of enzymatic denaturing.

The Maine State Fire Marshal’s Office determined the fire to be accidental, Smeltzer said. The fire originated from the stove.

On the actual day of the fire, the fire planners will again check such conditions as wind and moisture content in the vegetation. The wind direction will determine where the fire is started. Fire crews start the burn with a device called a drip torch. A drip torch is a can of fuel with a flame-carrying wick at the end. When the crewmember tilts the wick toward the ground, a flame streams out and ignites the vegetation. Most of the effort that goes into a prescribed fire is making sure that it is contained in the boundaries set for the fire. Firefighters and fire suppression equipment are near the site if the fire grows out of control (www.nps.gov/wica/fir-why.html, pgs. 1-3).

The second stage was emergent smoldering, which is when the combustion activity increases. The third stage that Steve Richard named was the free burning, this is when the rate and intensity of the fire increases. Heat in this case double every eighteen degree Fahrenheit temperature rise. In this stage the fire builds from the point of origin and spreads to upper areas of a structure. Flashover may occur if all combusting items in an area reach ignition

In the Article “Firefighters' Flame-Throwing Toolkits Keep Wildfires in Check” written by Chadwick Matlin it states “... backburning--in which professionals set brush alight before a wildfire does…”(Matlin). Back burning it best because it prevent wildfire and can since firefighter are starting the fire they can control the fire. This is also known as control burning. The use gelled gasoline(napalm) and drop it from an helicopter, ping pong ball sized sphere that then shoot out small amount of sparks that then start fire if the are has dry grass or dead wood, and the other thing they use is called the Green Dragon. It shoots flaming balls up to two hundred twenty-five feet.

Combustion is one of the five major chemical reactions that takes place. Usually, combustion occurs when a hydrocarbon (a compound formed of only bonded carbon and hydrogen atoms), reacts with oxygen gas to produce carbon dioxide and water (Helmenstine 2017). In the most basic terms, combustion occurs when any combustible material reacts with oxygen gas, yielding a product of water and carbon dioxide. The general equation for a combustion reaction can be written as; [hydrocarbon + oxygen → carbon dioxide + water ] . When a combustion reaction takes place, Combustion is labeled as an exothermic reaction, meaning that it releases heat energy.

It is also occur due to chemical reaction occur in the air by smoke mostly by the burning leather.

Dry Ice Volcano - Smokey Reaction - This is the slowest chemical reaction for slowly having smoke

Any ignition source such as an open flame, cigarette or electric spark could potentially ignite this flammable atmosphere to the point of flash fire or explosion.

For starters, why would someone want to burn property Many people assume that the people that are setting these fire are bad kids or teenagers acting out or looking for attention, but that not the case. The real reason is so people can lie to insurance company and gain money. Sometimes business owners hire professional arsonists to burn down there business without leaving a trace of arson. Other than that investigator might be dealing with a pyromaniac. A pyromaniac is a person who absolutely loves fire. The smell of gas or smoke sends them into ecstasy. Lighting a candle and blowing it out and relighting it and blowing it out repeatedly, watching the smoke lightly twirl around in the air, is a good sign of a pyro. Many pyros can figure out different types of gas and/or what's being burnt just from the
