Question

What is the final product in incineration?
(A)Fire
(B)Ashes
(C)Soil
(D)Solid waste

Answer 1

Hint: The final product in the incineration process is the solid remnants of fires. It is defined as non-aqueous and also the non-gaseous residues that remain after something burns. It is released after the combustion.

Complete answer:
Ashes is the final product in incineration. Incineration produces ash and bottom ash just as is the case when coal is combusted. the entire amount of ash produced by municipal solid waste incineration ranges from 4 to 10% by volume and 15–20% by weight of the first quantity of waste, and therefore the ash amounts to about 10–20% of the entire ash.

Additional Information: Incineration is known to be a waste treatment process that will be mostly involving the combustion of the organic substances which were present in waste materials. Incineration and other high-temperature waste treatment systems are known by the term "thermal treatment". The incineration of waste materials usually converts the waste into ash, flue gas, and heat. The ash which is formed is usually formed due to the presence of the inorganic constituents of the waste and should take the shape of solid lumps or particulates carried by the flue gas. The flue gases must be cleaned of gaseous and particulate pollutants before they're dispersed into the atmosphere. In some cases, the warmth that's generated by incineration is often wont to generate electrical power.
So, the correct answer is ‘Ashes’.

Note: The heat produced by an incinerator is often used to generate steam which can then be used to drive a turbine to supply electricity. The standard amount of net energy that will be produced per tonne of municipal waste is about 2/3 MWh of electricity and a couple of MWh of district heating.
