Direct Combustion Of Biomass For Heat Generation

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.

The majority of biomass power plants use direct combustion. In a cogeneration facility the steam from the boiler is captured to heat water and buildings. Although this is a dependable technology it only achieves a thermal efficiency of 20%. This can, however, be increased by cogeneration or by co-firing which is the burning of biomass along with coal. Another method being used is gasification of biomass.

In the article, the Burning Question, the issue of biomass energy via wood pellets was brought to question. This subject has deeply divided scientists, primarily from the chemistry and environmental science disciplines, economists, and politicians. Currently the use of wood pellets for energy, under the European Union, is classified as a carbon-neutral fuel. The argument for this designation lies in the regeneration of trees to take up the carbon released from burning past trees. However, many scientists call foul, basing their argument on the substantial lag period between burning trees and the regeneration of them. This period has led many to worry that such actions will worsen the current global warming crisis. Biomass energy plants produce,

The most commonly used type, regular unleaded gas (RUG) is readily available throughout the world. As a byproduct of crude oil, RUG is highly flammable though

A Pellet Stove Is An Efficient And Convenient Way To Add Heat To Your Home

In different nations, numerous individuals still rely on upon wood for fuel. GoSun stove depends on the sun's energy, which is renewable. This spares trees from deforestation and secures endangered species.

Fuels such as natural gas (methane) contain hydrocarbons. These are compounds of hydrogen and carbon only. When they burn, the carbon yields

To separate grain from paddy, we need tools like paddy separator and husker aspirator. By breaking paddy into smaller pieces, followed by segregation, we can obtain grains, which can be further processed to useful materials, and husks. This procedure echoes with pyrolysis, a process that uses machineries to separate useful and non-useful materials after breaking down the input substances to other materials. At this stage, what we have obtained is grain. To convert it to rice that can be consumed by human, we have to polish it and cook it. This action describes gasification, which turns carbon-containing compounds (grains) to energy-rich fuel (cooked rice) under

A common chemical reaction at my house is lighting the gas grill. We grill out almost every day, all year long in either rain or shine. Propane is naturally occurring and it is composed of eight hydrogen atoms and three carbon atoms. It is created by the decomposition and reaction of organic matter over long periods of time, along with a variety of other hydrocarbons like gasoline, crude oil and butane. Propane is a liquefied petroleum gas. It is more compact in a liquid state than in a gas state, which allows for easy transport and storage.

Based on the experimental results in Table 1, the Spruce Pointe Wood Pellets provided more enthalpy of combustion than the Inferno brand pellets. The results held true for all the trials as all three Spruce Pointe Wood Pellets on average had approximately 750 J/g more enthalpy then the Inferno brand pellets.

Pellet stove uses wood pellets to produce hot air to heat a house by burning these wood pellets in a combustion chamber in the presence of fuel that ensure the combustion process. Hot air goes out of the pellet stove through a fan.

Natural gas accounts for 29% of the world’s total energy and is used to produce 33% of the world’s electricity. Natural gas is one of the major sources of energy in urbanised areas. Natural gases are raw materials that are readily available from various sources and they occur naturally and are not produced by strenuous chemical means. When natural gas undergoes a combustion reaction it is often referred to as ‘clean burning’ because it does not significantly enhance the greenhouse effect which leads to global warming as opposed to the combustion of other

CO2 is the most significant greenhouse gas, which mainly comes from the use of fossil fuels. Many people feel that content of CO2 in the atmosphere is the main reason for manmade global warming. The main sources of CO2 emissions involve electricity generation, industrial processes, fumes from transportation and commercial buildings and use. Emissions of greenhouse gases, such as CO2, to the atmosphere are expected to cause even more of a significant change in global climate (Davison, 2007). The main focus to try to reduce the amount of carbon dioxide in the atmosphere is to reduce the amount that is released from coal-fired power plants. Greenhouse gas emissions that involve the productions of electricity come from natural gas production and coal-fired power plant operations. Natural gas production accounts for twenty-four percent and coal-fired power plant operations accounts for seventy-five percent, while the other one percent is caused by other electricity generation operations. The main reason why coal-fired power plants have a higher percentage of emissions is because the sulfur content of coal is much higher than that of other fossil fuels (Jarmaillo et al., 2007). This proves that there is a great need to find an alternative fossil fuel to use instead of coal. Although coal is easy to mine, transport and process for the electricity generation process, it is also the

In the world of global warming, all kinds of pollution and fuel shortages going on, renewable and clean/ green energy is increasingly the ideal solution of energy related problems we have to solve one way or another. Biofuel is one of the mainstream and highly supported solutions nowadays, an idea to make renewable fuel by living organisms such as fiber, corn, vegetable oil or sugar cane. Unlike nonrenewable fossil fuels over extracted by people causing various environmental problems like generating a considerable amount greenhouse gas, current technology already lets renewable fuel like biofuels to shrink a certain amount of greenhouse gas production, making it a more ‘clean’ source of energy.
