PULVERIZING PLANT In modern thermal power plant, coal is pulverized ground to dust like size and carried to the furnace in a stream of hot air. Pulverizing is a means of exposing a large surface area to the action of oxygen and consequently helping combustion. Pulverizing process consists 3 stages classified as: 1. Feeding 2. Drying 3.

14. Combustion Combustion is defined as the process of burning of a substance in the presence of air or oxygen with the liberation of light and heat. Lets see some Images. 15. Combustible Substances Substances that burn in air to produce light and heat are called combustible substances Eg Paper, Wood, Kerosene, LPG .

GASIFICATION • Gasification is a process that converts organic or fossil fuel based carbonaceous materials into carbon monoxide, hydrogen and carbon dioxide. This is achieved by reacting the material at high temperatures (>700 °C), without combustion, with a controlled amount of oxygen and/or steam. The resulting gas mixture is called syngas ...

Properties of Coal • Coal properties are evaluated by different methods. • The most commonly used methods are Proximate and Ultimate analysis of the coal. • Proximate analysis gives the Moisture, Ash and Volatile matter, while the Fixed Carbon is found by difference. • Ultimate Analysis gives the elemental composition of the coal.

3. Mining Methods • Coal is mined by two main methods surface or 'opencast' mining and 'underground' mining. • The choice of method is largely determined by the depth, geology of the coal deposit and other factors. • The majority of the world's coal production is coming from Opencast mines.

2. INTRODUCTION Coal was mined in America in the early 18th century, and commercial mining started around 1730 in Midlothian, ia. There were many coalfields, but the oldest were in Newcastle and Durham, South Wales, Scotland and the Midlands. Coal is primarily used for the generation of electricity, with much smaller volumes used for industrial process heat and in steel production. Over ...

What Is Coal Preparation? • Coal preparation is the removal of undesirable material (ash, Sulphur, moisture)from the RunofMine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities.

Shockingly: a 1000 MWe coal plant uses 9000 tonnes of coal per day, equivalent to an entire train load (90 cars with 100 tonnes in each!) 1. Firebox Before the coal is burned, it is pulverized to the fineness of talcum powder. It is then mixed with hot air and blown into the firebox of the boiler.
