Various characterization methods are used to investigate the physical and chemical properties of steel plant flying dust and waste oil sludge, and the combustion characteristics of the mixtures with pulverized coal are studied via thermogravimetric analysis; the catalytic combustion mechanism is also explored. The results show that two types of metallurgical byproducts with small particle ...

Transcribed image text: One way to clean up emissions of sulphur dioxide formed during the burning of coal is to pass the exhaust gases through a water slurry of powdered limestone. In the reaction sulphur dioxide reacts with calcium carbonate and oxygen gas to produce calcium sulphate and carbon dioxide. A coal burning plant that uses coal ...

with air heated to about 330 °C from the boiler. As the coal gets crushed by the rolling action, the hot air dries it and blows the usable fine coal powder out to be used as fuel. The powdered coal from the pulveriser is directly blown to a burner in the boiler. To burn pulverized coal successfully, the following two conditions must be satisfied:

The efficient burning of coal is a very dirty process to achieve the highest temperatures you use a "fluidized bed", that is, inject air into finely powdered coal. High temperatures = high efficiency. But you get lots of burning particles carried in the hot air stream. Keeping the flow velocity down you can let them turn harmlessly into ash ...
