USEFUL ARTICLES

Coal in electric power generating

Modern life is inconceivable without electricity. It illuminates our houses, streets, provides household and industrial heat. Thanks to him works electrical equipment, used in homes, offices and equipment in factories.

Improving access to energy around the world is a key factor in the fight against poverty. Who would have imagined that 1.6 billion people around the world (27% of the world's population) do not have access to electricity.

Steam, also known as steam coal, is used in power plants to generate electricity. The very first power plants used lump coal, which was burned on the grates in the boilers to raise steam. At present, coal is first pulverized to a fine powder, which increases the surface area and allows it to burn faster. In these pulverized coal systems, powdered coal is blown into the boiler chamber where it burns at high temperature.

Hot gases and thermal energy make water in the pipes lining the boiler, in steam.

Steam under high pressure enters the turbines, inside which there are impellers with many blades. He pushes these blades, causing the turbine shaft to rotate at a high speed. The generator, mounted on the other end of the shaft, consists of coils wrapped in wire. When they quickly rotate in a strong magnetic field - electricity is generated. After passing through the turbine, the steam condenses and returns to the boiler for reheating.

The generated electricity is converted to a high voltage of up to 400,000 volts. This is done to save and efficient transmission through power lines.

When the consumer's point is reached, that is, our homes, electricity is converted to a more safe voltage of 100-250 volts.

Modern technologies of pulverized coal systems are well developed, accounting for 90% of all world capacities. The improvement and modernization of pulverized-coal systems continues, new methods of combustion are being developed. This will allow generating more electricity from less coal - improving the thermal efficiency of power plants.

Coal in iron and steel production

Steel is important in human life. Cars, trains, buildings, ships, bridges, refrigerators, medical equipment - all made of steel.

It is necessary for the creation of machines that today help to produce almost everything that surrounds us in everyday life.

Coal is an important component for the production of iron and steel. About 64% of the steel is produced from cast iron produced in blast furnaces that use coal. Annually in the world about 1 billion tons of steel are produced, which consumes about 550 million tons of coal.

Blast furnace uses iron ore, coke (obtained from coking hive) and limestone in small quantities. Some furnaces use cheaper steam coal, better known as blown fuel pulverized fuel, for greater cost savings.

Coke is produced from coking coals having physical properties that facilitate their melting, and then harden into porous pieces under the influence of temperature and without air access. Coking coals should also have a low content of sulfur and phosphorus. Being relatively scarce, they are more expensive than steam coals used in electricity generation.

Coking coal is crushed and cleaned. Then it passes through a series of coke ovens, known as coke batteries. During this process, by-products are removed and coke is produced.

In the blast furnace, raw materials (iron ore, coke and fluxes) are fed through the upper part of the furnace. The air is heated to approximately 1200° C. and blown into the furnace through the nozzles in the lower section. By blowing air into the coke burns, releasing carbon monoxide, which begins a chemical reaction. Iron ore is reduced to iron by removing oxygen. As a result, iron is obtained - an alloy of iron with carbon.

Cast iron is used in converter furnaces with the addition of a large amount of lime and blowing oxygen with a purity of at least 99%. The reaction with oxygen raises the temperature to 1700° C, oxidizing impurities, and creating steel of various grades. On average, 0.63 tons of coke is used to produce 1 ton of steel.

Coal in the production of cement

Cement plays an important role in the construction industry. It mixes with water, sand, gravel and slag, forming concrete - the main building element in modern society. More than 1,350 million tons of cement are used worldwide every year.

Cement is made from a mixture of calcium carbonate (usually in the form of limestone), silicon dioxide, iron oxide and aluminum oxide. The high temperature in the kiln, mostly coal-fired, heats the feed to partial melt at 1450 ° C, turning them chemically and physically into a substance known as clinker. These are gray granules that give cement its binding properties. The clinker is mixed with gypsum and ground to fine powder to make cement.

In the production of cement, coal is used as an energy source, which requires a large number. Usually coal in furnaces is burned in the form of a powder. To produce 1 kg of cement, approximately 0.5 kg of coal is needed. Most likely coal will remain an important, integral part of the cement production process for many years to come.

Coal combustion products (POCs) can also play an important role in the production of concrete. PSUs are by-products and are formed from the combustion of coal in coal-fired power plants. They include ashes, ash residue, scale, etc. Ash, for example, can be used to add together with cement in concrete. Thus, the processing of coal combustion products has a beneficial effect on the environment, acting as a supplement or replacement of the main raw materials.
