The most common kind fuel for boiler The most common kind fuel for gas fired boilers in North America is natural gas. The reason why natural gas is used in boilers is obvious in most areas it is the cheapest heating fuel available. The main reason why natural gas is so cheap is that it is normally pumped directly to homes and business through buried pipes. In most areas these pipes serve most homes and businesses. All a person normally has to do to get natural gas delivered to their home is

will be focused upon in this analysis is hydrogen as a source of fuel‚ and the technology leading the way to making it a reality. This technology would affect everyone in one way or another if correctly used. So we must ask if this technology is beneficial to us‚ how it might hurt us‚ and whether it is worth pursuing from an ethical stance. Background: Hydrogen has already been under the micro scope for many years as an alternative fuel source to us because of its abundance and power. We have simply

The roles of Zoos in conservation The main aim of zoos is to protect and conserve global biodiversity and wildlife. To do this they have four roles to play which are; research‚ conservation‚ education and welfare. Research: Research is the careful search or inquiry for new facts by scientific study of a subject‚ through a course of critical investigation. By studying animals we can learn new things about their behaviour and lifestyle. The Secretary of State’s Standards of Modern Zoo Practice

The "fuel cell cars" currently being advertised are being touted as "having no emissions except water." In a limited sense that is‚ in fact‚ true. However‚ if the entire fuel cycle for the car is considered it most certainly is not. The fuel used by the fuel cell is hydrogen‚ very pure hydrogen. Combined with oxygen from the ambient air‚ the fuel cell produces electricity that powers an electric motor and other devices in the vehicle--just like the battery-driven electric vehicles already on the

Quantitative Conservation of Momentum Name: ______________________________________ 1. Kim holds a 2.0 kg air rifle loosely and fires a bullet of mass 1.0 g. The muzzle velocity of the bullet is 150 m/s. Find the recoil speed of the gun. Momentum conservation equation: Recoil speed =________________ 2. If the girl in the previous question holds the gun tightly against her body‚ the recoil speed is less. Calculate the new recoil speed for the 48 kg girl. Momentum conservation equation:

The conservation movement was a controversial topic nationwide. Some people supported it‚ while others thought it was absurd to take away natural resources that were necessary to live. Regardless‚ whether you supported the movement or not‚ it did effect you because of the substantial change it brought to the United States. The conservation movement was founded for a plethora of reasons in order to better the country. The conservation movement was founded because of the questions about who should

Energy Conservation 1 Energy conservation is the reduction or elimination of unnecessary energy use and waste. This practice may result in increase human comfort‚ personal security‚ national security‚ environmental value‚ and financial capital. There are many activities that people can do to conserve energy and help not only themselves‚ but also the environment and everyone around them. Conserving energy is important because most of our current energy sources are not renewable. When using

Describe and explain how the use of Fossil fuels may affect the environment and discuss measures‚ which could be taken to reduce the harmful consequences Fossil fuels include gasoline‚ oil‚ coal‚ or natural gas. Whenever we burn them‚ more pollutant gases are emitted into the atmosphere. They are burned to run cars and trucks‚ heat homes and business and power factories and are responsible for about 98% of U.S carbon dioxide emissions‚ 24% of methane emissions and 18% of nitrous oxide emissions.
