The Combustion Of Household Fuels

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

The purpose of the lab was to determine the ratio of air to acetylene results in complete combustion of acetylene gas. The balanced chemical equation for this experiment was C2H2(g) + O2(g) --> CO2(g)+ H2O(l). Complete combustion is the reaction of an element or compound with oxygen to produce the most common oxides and energy. Complete combustion occurs when the fuel and oxygen combine in exact proportions to completely burn the fuel, which leaves a clean test tube. Incomplete combustion is the reaction of an element or compound with oxygen to produce some oxides with less oxygen than the most common oxides. Incomplete combustion occurs when there is not enough oxygen to react

This graph is identical to experiment 1 graph 1 as it compares the experimental and theoretical molar heats of combustion. Being the same concept this graph shows how the experimental molar heat of combustion is a scale less than the theoretical molar heat of combustion. The significance behind the scale of this graph where the experimental is lower that the theoretical, is how there is a pattern for which every fuel follows the same trend. Also it shows the average heats of combustion and which alkane has the leading heat output rate.

Many combustion reactions involve the burning of organic compounds called hydrocarbons, compounds containing the elements carbon and hydrogen, or other organic compounds. When a hydrocarbon is burned completely, the products of the combustion reaction are usually carbon dioxide and water. Natural gas, propane, and wood all burn to produce carbon dioxide and water as the products.

As the differences between Legacy (circa 1950-1970) and Modern fires (circa 1980-2017) are explored, one must examine and answer a few questions. When is oxidation not combustion? When is combustion not oxidation? What is the basic mechanism of fire spread? How does legacy fires differ from modern fires in fire growth? These questions and the findings associated directly correlate to the study and findings of multiple controlled lab experiments conducted by the Underwriters Laboratories (UL) in 2012. Underwriters Laboratories is a global, non-profit safety organization. UL tests, certifies, verifies, inspects, audits, advises and educates in many markets.

2. One qualitative observation that one could use to determine whether the combustion is complete or incomplete is the sound that is produced during the combustion. The sound a complete combustion would make should be an abrupt popping sound, while the sound an incomplete reaction would make should be a soft whoof sound.

Baking Soda - This common ingredient, when heated produces Carbon Dioxide gas. Since the fire would be getting carbon dioxide, the amount of oxygen the fire would be receiving would be limited resulting in the fire being stopped as oxygen is one thing that is required for combustion.

When we add fourth element that is chemical reaction in above mentioned three elements then this is baptized fire tetrahedron. Fire Triangle Elements Fire Tetrahedron Elements Heat Heat Fuel Fuel Oxygen Oxygen Chain reaction Question # 3 Discuss how the “Fire Tetrahedron” can be used to understand the combustion process. Answer#3: The combustion reaction can be considered by four constituents, the fuel, the oxidizing agent, heat and fourth one is abandoned chemical

These gases include but are not limited to “carbon monoxide, methane… and hydrocarbons” (Flower 1). When you inhale too much of these harmful gases you may be at risk for “ Breathing problems, bronchitis… Asthma, and chest pains.” (Flower 1). Along with these harmful gases are particles referred to as microns. Microns are sharp dust and smoke particles that are very harsh on your lungs and enter your bloodstream and can harm your vital organs. For small children, the elderly, and those who already suffer from respiratory problems, heart problems and diabetes, ten or more micrograms of microns per cubic centimeters can be extremely agonizing or fatal (Honn 1). Reaching that amount of microns can happen in two different ways. The first and most rare way is that, the density of microns comes straight from the smoke of one tree, which is rare because less than a percent of tree’s in the world can do that. The second way is that the smoke sits in one area and builds up its density due to lack of wind or rain. Regardless of how a wildfire starts the smoke it dissipates into the air is harmful to humans, therefore there is no need to “fuel the flame” by having controlled or prescribed burns. The smoke that is being released into the air that we breathe is not controllable by humans, but then

Pellet stove and pellet boiler both work to heat a house, each one has its own way of heating it.

Fuel combustion is the process of where fuel is burnt that releases heat and light which is an exothermic reaction meaning it releases heat. The fuel is a hydrocarbon, which reacts with oxygen to release energy however a small amount of heat energy is needed to start fuel combustion. The products to the reaction are carbon dioxide and water.

A plant or a booster burn pattern is said to be a pattern of any preparation for the unlawful setting of a fire, primarily the material is put around the ignition device to feed the initial flame. Fortunately, for this pattern newspaper is normally the most popular material. However, wood shavings, rags, blankets, clothing and cotton waste is the most highly used material for industrial and factory fires. Therefore, these are also some of the common plants that can start a fire. Yet, any form of liquid or flammable fluid such as gasoline or kerosene which are considered the most popular one to use when starting a fire. Unfortunately, they are not the only flammable fluids that are used because alcohol, lighter fluid and

There are four main things that stem off of fuel emissions, these are carbon monoxide, nitrogen oxides, particulate matter and unburned hydrocarbons. These are formed by the fuel being burned and released through the combustion reaction. The main components of gasoline that combust in gasoline are isooctane, butane, 3-ethyltoluene and an octane enhancer called MTBE (methyl tert-butyl ether).

When the fuels are burnt, energy is given off. I will be calculating the energy given off using the formula above. The specific heat capacity is the energy

The aim of this experiment was to test the heat of combustion over a period of time, and the energy required to combust alcohols with different carbon chain levels. It was hypothesised that the higher the carbon chain of the alcohol present, the faster the heat of combustion will occur. Meaning more energy will be released for a higher carbon chain. After calculating the results from the experiment it was found that the hypothesis was partially supported. The reasoning for this is as the alcohol that posses a higher carbon chain, generally increased there reaction rates. However there were a few exceptions to this rule.
