Chemical Composition of Smoke

Q(Lab) : I'm looking for information on what the combustion products are for each type of combustible, can you help me?

A(ChatGPT) : Sure, I can help you with that. However, the combustion products depend on the type of combustible being burned. Here are the common types of combustibles and their combustion products:

Hydrocarbons (such as natural gas, propane, gasoline, and diesel fuel) - The combustion products of hydrocarbons are water vapor (H2O) and carbon dioxide (CO2), along with other gases such as carbon monoxide (CO) and nitrogen oxides (NOx) that are produced depending on the combustion conditions.

Biomass (such as wood, charcoal, and agricultural waste) - The combustion products of biomass are primarily water vapor (H2O), carbon dioxide (CO2), carbon monoxide (CO), and small amounts of other gases like nitrogen oxides (NOx) and sulfur dioxide (SO2).

Coal - The combustion products of coal depend on the type of coal being burned, as well as the combustion conditions. Generally, coal combustion produces carbon dioxide (CO2), water vapor (H2O), and sulfur dioxide (SO2). Incomplete combustion can also produce carbon monoxide (CO), nitrogen oxides (NOx), and particulate matter.

Oil - The combustion products of oil depend on the type of oil being burned, as well as the combustion conditions. Generally, oil combustion produces carbon dioxide (CO2), water vapor (H2O), and sulfur dioxide (SO2). Incomplete combustion can also produce carbon monoxide (CO), nitrogen oxides (NOx), and particulate matter.

It's important to note that the composition of the combustion products can vary depending on factors such as the type of combustible, the amount of oxygen available for combustion, and the temperature of combustion. Additionally, the presence of impurities in the combustible or the combustion process can result in the production of additional pollutants.

Q(Lab) : I would like to know how much combustibles such as CO2 and CO are generated during combustion of each type of combustibles such as beds, chairs, and oil.

A(ChatGPT) : The amount of CO2 and CO generated during the combustion of different types of combustibles can vary depending on several factors such as the type of combustible, the amount of oxygen available for combustion, and the temperature of combustion. Additionally, the presence of impurities in the combustible or the combustion process can also affect the amount of CO2 and CO generated.

Here are some estimated values for the CO2 and CO generated during the combustion of different types of combustibles:

Wood: When burned under normal combustion conditions, wood produces an estimated 1.7 pounds of CO2 and 0.02 pounds of CO per pound of wood burned.

Coal: The amount of CO2 and CO generated during the combustion of coal can vary depending on the type of coal being burned, as well as the combustion conditions. Generally, coal combustion produces an estimated 2.4 pounds of CO2 and 0.03 pounds of CO per pound of coal burned.

Oil: The amount of CO2 and CO generated during the combustion of oil can vary depending on the type of oil being burned, as well as the combustion conditions. Generally, oil combustion produces an estimated 3.1 pounds of CO2 and 0.03 pounds of CO per pound of oil burned.

Natural gas: When burned under normal combustion conditions, natural gas produces an estimated 0.12 pounds of CO2 and 0.0001 pounds of CO per cubic foot of gas burned.

Propane: When burned under normal combustion conditions, propane produces an estimated 0.12 pounds of CO2 and 0.0001 pounds of CO per cubic foot of gas burned.

As for the combustion of materials such as beds and chairs, the amount of CO2 and CO generated would depend on the type of materials used, as well as the combustion conditions. However, burning of such materials can be dangerous and cause toxic smoke, and therefore it is not recommended to burn them. Instead, they should be disposed of properly.

Q(Lab) : Can you point me to an organization or website that provides the material you provided above?

A(ChatGPT) : Certainly! Here are some reputable organizations and websites that provide information on combustion products for various types of combustibles:

Q(Lab) : Can I get the mass per hour (kg/s) of the substances (ex. CO, CO2, CH4, N2, Hs and so on) produced when the curtain burns?

A(ChatGPT) : The mass per hour of substances produced when a material burns depends on several factors, such as the type of material being burned, the combustion conditions, and the air-fuel ratio.

Assuming that you are referring to a typical household curtain made of synthetic fibers, the main components that will be released during combustion are carbon dioxide (CO2), water vapor (H2O), and potentially small amounts of carbon monoxide (CO) and nitrogen oxides (NOx). Methane (CH4) and hydrogen sulfide (H2S) are not typically produced during the combustion of synthetic materials.

The exact amount of each substance produced would depend on the specific composition of the material and the combustion conditions, but as a rough estimate, the combustion of 1 kg of synthetic fibers would produce approximately 3 kg of CO2 and 1.5 kg of H2O, with smaller amounts of CO and NOx.

It is worth noting that the combustion of any material produces potentially harmful gases and particulate matter, and it is important to ensure that proper safety measures are in place to prevent fires and minimize exposure to these substances.

Q(Lab) : can you tell me the amount of CO and NOx also even it is not acurate

A(ChatGPT) : Sure, as a rough estimate, the combustion of synthetic fibers may produce around 0.01-0.02 kg of carbon monoxide (CO) and 0.001-0.003 kg of nitrogen oxides (NOx) per kg of material burned. However, please keep in mind that these values can vary widely depending on the specific conditions of the combustion process, and that the actual values may be higher or lower than these estimates. It's also worth noting that both CO and NOx are harmful pollutants, and measures should be taken to minimize their emissions.

Q(Lab) : Can I get the mass per hour (kg/s) of the substances (ex. CO, CO2, CH4, N2, Hs and so on) produced when the mattress burns also?

A(ChatGPT) : The mass per hour of substances produced when a material burns depends on several factors, such as the type of material being burned, the combustion conditions, and the air-fuel ratio.

Assuming that you are referring to a typical household mattress made of foam and synthetic fibers, the main components that will be released during combustion are carbon dioxide (CO2), water vapor (H2O), carbon monoxide (CO), nitrogen oxides (NOx), and potentially small amounts of other compounds such as hydrogen cyanide (HCN) and sulfur dioxide (SO2).

The exact amount of each substance produced would depend on the specific composition of the material and the combustion conditions, but as a rough estimate, the combustion of 1 kg of a typical household mattress may produce approximately 3 kg of CO2, 1.5 kg of H2O, 0.02 kg of CO, and 0.002 kg of NOx, along with smaller amounts of other compounds such as HCN and SO2.

It's important to note that the combustion of any material produces potentially harmful gases and particulate matter, and it's essential to ensure that proper safety measures are in place to prevent fires and minimize exposure to these substances.

Q(Lab) : can you tell me the amount of HCN and SO2 also even it is not acurate

A(ChatGPT) : Sure, as a rough estimate, the combustion of a typical household mattress may produce around 0.0005-0.001 kg of hydrogen cyanide (HCN) and 0.0001-0.0005 kg of sulfur dioxide (SO2) per kg of material burned. However, please keep in mind that these values can vary widely depending on the specific conditions of the combustion process, and that the actual values may be higher or lower than these estimates. It's also worth noting that both HCN and SO2 are harmful pollutants, and measures should be taken to minimize their emissions.
