Write any four characteristics of a good fuel?

Answer 1

There are a number of different fuels in use today. And, fuel choice would depend in part on the application. For example, Bunker Oil might not be an appropriate fuel for your kitchen stove. And, likewise methane might not be an appropriate fuel for a ship.

A few generic criteria might include:

• Able to utilize atmospheric Oxygen as an oxidizer.
• Easy to store.
• Stable in storage.
• Cheap and easy to transport
• Transportation can use existing infrastructure
• Liquid in the range of temperatures it is likely to be used.
• Cheap.
• Minimum amount of energy to produce.
• Safe to transport.
• Safe in case of an accident.
• Low environmental toxicity in case of a spill.
• Low toxicity with contact, inhalation, ingestion by humans & animals.
• Not corrosive to materials it will be in contact with.
• Quick changes.
• Safe to change out.
• Lots of power.
• Low toxicity or ill effects of exhaust products
• Easy to start vehicle or application
• CARBON NEUTRAL, OR DOES NOT USE UP FOSSIL FUELS
• Can be used in conjunction with existing technologies.
• Doesn't significantly contaminate oil or cause harm to engine
• Fuel efficient in existing vehicles

Obviously the choice is very dependent on the application.

A few of the fuels that are in use in vehicles... will hit several factors, but also miss a few:

• Gasoline.
  Relatively toxic.
  Uses fossil fuels, not carbon neutral.
  Emissions - ???
  Safety, flammable, but reasonably safe in modern cars.
  Easy to start in a variety of temperatures.
• Diesel.
  Relatively toxic.
  Uses fossil fuels, not carbon neutral.
  Emissions - issues with smoking.
  Safety, less explosive than gasoline.
  May have starting difficulties at extreme cold temperatures. May require preheating
• Biodiesel
  Relatively non-toxic.
  Carbon Neutral, little or no fossil fuels.
  Emissions - issues with smoking.
  Safety, less explosive than gasoline, less toxic than gasoline/diesel.
  May have issues starting in cold weather
  Issues with gelling in cold weather & may require preheating or preheated delivery system.
  We may not have adequate production capacity.
• Ethanol
  Relatively non-toxic
  Carbon Neutral
  Works in gasoline engines
  May have issues with transportation in Gasoline pipelines.
  May be inefficient to produce
  Issues with starting in cold weather, may require mix with other fuel, at least during starting
  Low emissions.
• Methane/Propane
  May or may not be carbon neutral depending on the source. Longer to refuel.
  No fueling infrastructure
  Dangers in crashes & inherent dangers of pressurized tanks, especially high pressures in LNG
  Easy conversion for gasoline vehicles
  Very low emissions.
• Hydrogen
  Carbon Neutral
  Not naturally occurring, needs energy to produce.
  Inefficient to produce
  No existing transportation infrastructure, but could be "made onsite" resolving some transportation issues
  No existing delivery network
  Very difficult to handle.
  Low toxicity other than potential issues from pressure or cold.
  Finite life for tanks, may also leak from tanks at a slow rate
  Very low emissions.
• Battery Power
  Technically carbon neutral. Contains chemicals that can be recycled.
  Efficiency?
  Existing power grids may not be adequate to support
  Slow recharging
  May contain toxic/dangerous chemicals in crashes/spills.
  Very low emissions (none, except for spills).

Answer 2

1. It should be fairly inexpensive.

2. It should be readily available.

3. It should have a high calorific value.

4. It should be readily combustible in a manner that can be controlled, i.e., it should burn at a moderate rate.

5. It should produce minimum amount of harmful products during burning. That means it should produce minimum pollution.

Answer 3

A good source of energy should have the following characteristics:

• It should do a large amount of work per unit mass or volume - it means that the output energy must be more than the input energy. It should have high calorific value.
• It should be easily accessible - the energy source should be able to provide energy over a long period of time. Example: coal and petroleum.
• Should be easy to store and transport - most common sources of energy such as coal, petrol and LPG need to be transported to users from their points of production. They also need proper storage. Thus it is important to store and transport these sources safely and economically.
• Safe and convenient to use - energy sources should be safe as it is used by a large number of people and should be convenient.

Example: Nuclear energy from a nuclear power plant is hazardous to be used at homes.

Answer 4

Needs to ignite easily, be transported easily, release a lot of energy when burnt and be cheap.

Answer 5

This is the ability to burn releasing heat.

Answer 6

1. High energy content
2. Easy availability
3. Clean combustion
4. Cost-effective

Answer 7

it's combustibility

Answer 8

High flammability
