What problems do particulates cause?
Numerous scientific studies have linked particle pollution exposure to a variety of problems, including: premature death in people with heart or lung disease. nonfatal heart attacks. irregular heartbeat.
What are the products of burning fossil fuels?
Products formed during combustion of fossil fuels. The primary pollutants are Carbon Monoxide (CO), Carbon Dioxide (CO2), Sulfur (SO2), Nitrogen Dioxide (NOx), Nitric Oxide (N2O), Volatile organic compounds (VOCs), and Hydrocarbons (HCs).
Can you burn carbon?
The most common form of burning in everyday life is carbon combustion. In carbon combustion, carbon atoms break their bonds with each other and with other atoms (which requires energy) to form bonds with oxygen atoms (which releases even more energy than first required).
What factors make a good fuel?
A good fuel should have the following characteristics.
- It should be easily available.
- It should be cheap.
- It should have a high calorific value.
- It should have a low ignition point, which is not lower than room temperature (so that it does not catch fire at room temperature).
- It should not burn too fast or too slowly.
What are 3 Properties that a good fuel should have?
- It should possess high calorific value.
- It should have proper ignition temperature.
- It should not produce poisonous products during combustion.
- It should have moderate rate of combustion.
- Combustion should be easily controllable i.e., combustion of fuel should be easy to start or stop as and when required.
What is a good fuel give example?
Chemical
| Primary (natural) | Secondary (artificial) | |
|---|---|---|
| Solid fuels | wood, coal, peat, dung, etc. | coke, charcoal |
| Liquid fuels | petroleum | diesel, gasoline, kerosene, LPG, coal tar, naphtha, ethanol |
| Gaseous fuels | natural gas | hydrogen, propane, methane, coal gas, water gas, blast furnace gas, coke oven gas, CNG |
Which fuel is ideal fuel?
Ideal fuel is a fuel which on burning doesn’t emit harmful gases it is easy to transport and store it is also of very low cost and gives more heat per weight ,It also have a high calorific value.It should have low ignition temp. ex. -Natural gas,LPG,CNG.
Which is ideal fuel of energy?
The purpose of the fuel is to convert its chemical energy into heat and other forms of energy on burning. An ideal fuel must have high calorific value to serve the purpose better….The SI Unit to Measure Calorific Value is J/kg.
| Fuels | Calorific Value (J/kg) |
|---|---|
| Coal | 25000-33000 |
| Petrol | 45000 |
| Kerosene | 45000 |
| Diesel | 45000 |
What is the ignition temperature of a good fuel?
At 1 atm. The ignition temperature depends on the air pressure. Under standard conditions for pressure….Autoignition point of selected substances.
| Substance | Autoignition | Note |
|---|---|---|
| Gasoline (Petrol) | 247–280 °C (477–536 °F) | |
| Hydrogen | 535 °C (995 °F) | |
| Iron | 1,315 °C (2,399 °F) | 1315±20 |
| Lead | 850 °C (1,560 °F) | 850±5 |
