Q:

Which gasifier equipment has inability to operate on a number of unprocessed fuels?

A) Counter current gasifier B) Cross draught gasifier
C) Co-current gasifier D) Fluidized bed gasifier
 
Answer & Explanation Answer: C) Co-current gasifier

Explanation: Down draught gasifier or co-current gasifiers equipment lies in its inability to operate on a number of unprocessed fuels. In particular, fluffy, low density materials give rise to flow problems and excessive pressure drop and the solid fuel must be pelletized before use.

Q:

Which gasifier has a minimum tar converting capability?

A) Counter current gasifier B) Cross draught gasifier
C) Co-current gasifier D) Fluidized bed gasifier
 
Answer & Explanation Answer: B) Cross draught gasifier

Explanation: A disadvantage of cross draught gasifiers is their minimal tar converting capacity and the consequent needs for the high quality charcoal. It is because of the uncertainty of charcoal quality that a number of charcoal gasifiers employ down draught principle, in order to maintain at least a minimal tar cracking capability.

Q:

Which gasifier has better tar converting capacity?

A) Counter current gasifier B) Cross draught gasifier
C) Co-current gasifier D) Fluidized bed gasifier
 
Answer & Explanation Answer: C) Co-current gasifier

Explanation: A solution to the problem of tar entrainment in the gas stream has been found by designing co-current or down draught gasifiers, in which primary gasification air is introduced at or above the oxidation zone in the gasifier.

Q:

Which is the gasifier that can be operated in small scale/amounts?

A) Counter current gasifier B) Cross draught gasifier
C) Co-current gasifier D) Fluidized bed gasifier
 
Answer & Explanation Answer: B) Cross draught gasifier

Explanation: It is actually the advantage of this system that it is capable of handling very small amounts for operation. Installations below 10 KW can under certain conditions be economically feasible. The reason is the very simple gas cleaning train which can be employed when using this type of gasifier.

Q:

Which is the oldest and simplest type of gasifier?

A) Counter current gasifier B) Cross draught gasifier
C) Co-current gasifier D) Fluidized bed gasifier
 
Answer & Explanation Answer: A) Counter current gasifier

Explanation: The oldest and simplest type of gasifier is the counter current or up draught gasifier. The major advantage of this type of gasifier are its simplicity, high charcoal burnout and internal heat exchange leading to low gas exit temperatures and high equipment efficiency.

Q:

A device for converting substances (chemically or physically) into gas is called ______

A) Gasifies B) Biogas plants
C) Draughts D) Gas chambers
 
Answer & Explanation Answer: A) Gasifies

Explanation: The word Gasification implies converting a solid or liquid into a gaseous fuel without leaving any solid carbonaceous residue. Gasifier is a equipment which can gasify a variety of biomass such as wood waste, agricultural waste like stalks, and roots of various crops. The gasifier is essentially a chemical reactor where various complex physical and chemical processes take place.

Q:

What is the full form of VRA?

A) Vibration resistant appliance B) Vehicle Refueling Appliances
C) Volatile removal assembly D) Validated requirement authority
 
Answer & Explanation Answer: B) Vehicle Refueling Appliances

Explanation: Vehicle refueling appliance is abbreviated as VRAs. Certified natural gas compressors for refueling the vehicles are commercially available. These allow refueling at home and work. After upgrading with the above-mentioned technologies, the biogas (transformed into biomethane) can be used as vehicle fuel in adapted vehicles.
