What else can I help you with?
Which energy sources produce carbon dioxide and sulphur dioxide?
Burning coal (a fossil fuel) releases carbon dioxide and sulphur dioxide.
Why does a power-station owner prefer to buy a low-sulphur coal than ordinary coal?
The sulphur in fuels produces sulphur dioxide when it burns, which is a major cause of acid rain. Low sulphur fuels are less polluting.
What element does coal contain to make sulphur dioxide when it burns?
Coal contains sulfur, which combines with oxygen during combustion to form sulfur dioxide (SO2). Burning coal releases this harmful gas, contributing to air pollution and acid rain.
Why do you analyze sulfur in coal?
The amount of sulphur in coal is directly related to the amount of sulphur dioxide it would produce on burning and hence it becomes necessary to check sulphur content since there are emission limits on amount of sulphur dioxides that can come out since it is an air pollutant. To remove sulphur one might consider adding carbonates as it would help convert sulphur dioxide to sulphates which can be removed along with the ash.
What are two disadvantages of coal as a fuel?
it hurts the environment by realising carbon dioxide, sulphur dioxide, ash etc.
Is sulfur trioxide a primary or secondary pollutant?
Coal and oli contain sulphur. When either one burns, it produces sulphur dioxide. The sulphur dioxide gradually turns into sulphur trioxide which mixes with rain and becomes acid rain. It is easy to remove the sulphur in refineries or power plants.
What are the emissions from coal combustion at thermal power plants?
Oxides of Nitrogen Oxides of Sulphur
What effect does sulfur dioxide have on plants?
Sulphur dioxide is very harmful to plants and it can kill them. Sulphur Dioxide is the main gas produced by the burning of coal and it is cleared into the atmosphere. Moreover Sulphur Dioxide can react with water vapour in the atmosphere and produce a dangerous acid called sulphuric acid which is the acid in acid rain. Sulphuric acid can break plants (and animals) down, therefore the plants die. i love does nuts
When coal is burnt in power stations which oxides can be released which can react with water vapour in clouds to form acid rain?
the sulphur is a base in fossil fuels (in this case coal). when the coal burns the sulphur reacts with the oxygen in the air to produce sulphur dioxide which reacts with water vapour to form acid rain
What kind of doxide does coal produce?
Combustion of coal produces Carbon Dioxide, Sulphur Dioxide. It also produces Coke(Impure Carbon) , Water vapour, and Ammonia.
How the acid rain happens?
Coal is made from trees that died long ago and were covered with dirt that turned to rock. Coal contains the same inorganic elements as trees and in the same percentages. One of those elements is sulphur. When coal burns, it produces a lot of carbon dioxide and a little bit of sulphur dioxide. Power plants and refineries can use scrubbers to remove sulphur dioxide from smoke or they can let it go into the atmosphere. When the sulphur dioxide reaches the atmosphere, it slowly turns into sulphur trioxide. When a molecule of sulphur trioxide meets with a molecule of water vapor, it forms a molecule of sulphuric acid, an extremely powerful acid. This joins other molecules of water to create dilute sulphuric acid. This falls as rain, acid rain. Petroleum also contains sulphur but the sulphur is generally removed in the refining process.
Which will emit while coal combution at thermal power plant?
1.carbon dioxide 2.oxides of sulphur and nitrogen.
