The burning of a solid material may appear to lose weight if the mass of combustion gases (such as carbon dioxide and water vapor) are not taken into account. The original mass of flammable material and the mass of the oxygen consumed (typically from the surrounding air) equals the mass of the flame products (ash, water, carbon dioxide, and ...
Combustion of a liquid fuel in an oxidizing atmosphere actually happens in the gas phase. It is the vapor that burns, not the liquid. Therefore, a liquid will normally catch fire only above a certain temperature: its flash point. The flash point of liquid fuel is the lowest temperature at which it can form an ignitable mix with air.
The flue gas is primarily CO 2, suitable for sequestration. The concentration of pollutants in the flue gas is higher, making separation easier. Most of the flue gases are condensable; this makes compression separation possible. Heat of condensation can be captured and reused rather than lost in the flue gas.
In chemistry, the burn rate (or burning rate) is a measure of the linear combustion rate of a compound or substance such as a candle or a solid propellant. It is measured in length over time, such as millimeters per second or inches per second. Among the variables affecting burn rate are pressure and temperature.
Common household items and objects can accelerate a fire. Wicker and foam have high surface to mass ratios and favorable chemical compositions and thus burn easily and readily. Arsonists who use large amounts of available combustible material rather than ignitable liquids try to avoid detection. Using large fuel loads can increase the rate of ...
If hot enough, the gases may become ionized to produce plasma. [2] Depending on the substances alight, and any impurities outside, the color of the flame and the fire's intensity will be different. [3] Fire, in its most common form, has the potential to result in conflagration, which can lead to physical damage, which can be permanent, through ...
The decision by Phillips 66 this week to shutter its refinery in Wilmington next year will wipe out more than 8% of the state's crude oil processing capacity. Another refinery shuts down in ...
By convention, the (higher) heat of combustion is defined to be the heat released for the complete combustion of a compound in its standard state to form stable products in their standard states: hydrogen is converted to water (in its liquid state), carbon is converted to carbon dioxide gas, and nitrogen is converted to nitrogen gas.
