When Buying Coal On Coal Bag;
– Calorie value,
– Ash rate,
– Sulfur rate,
– Swelling index value,
– Production and final consumption date,
– Information such as manufacturer, address, telephone and e-mail address should be written.
Pay attention to calories when buying coal
Remember, it is the calorie of coal that does not heat you.
– Instead of low-calorie 2000 kg of poor quality coal, it is possible to heat it with 1200 kg of high calorie coal.
It is possible to heat ash and moisture with 1200 kg coal of low quality instead of 2000 kg ash and high quality coal.
– You can cut your coal consumption in half by purchasing 7,000 KCal / kg of coal instead of 3500 KCal / kg of coal.
– Low calorie coal, expensive coal. Please note that if the calorie of the coal you will buy is 3500 KCal / kg, you will have to use 2 times more coal than the coal with calorie 7000 KCal / kg.
– When purchasing coal, always question the calories of coal.
Pay Attention to Moisture When Buying Coal
– High humidity, low calorie coal means bad and expensive coal even if it is cheap.
– When you want to burn coal with high humidity, more coal is needed. Because more energy is needed to remove the moisture in the coal.
– Please pay attention to the moisture of the coal you buy.
Be careful to be bagged when buying coal
– Buy bagged coal,
– It contains poor quality, low calorie, sulfur-forming amount of sulfur when burned. Please note that the moisture and ash of the coals sold in the open is high.
– When you buy coals sold in the open, you cannot make any claims about the coal.
– When purchasing bagged coal, select a few bags and weigh them. Make sure its weight is correct.
– It is forbidden to sell and buy coal in the open.
– Analyzes of bagged coal will be carried out free of charge to consumers (provided they have invoices).
– Please inform those who buy bagless (open) coal in your environment, to the Provincial Directorate of Environment and Urbanization and Municipalities in your city.
– Please see if there is information on the bag that shows the name of the company, the origin and type of coal, the lower heat value of the coal on the original basis, the total amount of sulfur on the dry basis, the amount of moisture on the original basis, the size, the address and the phone number of the company.
– If you want to breathe fresh air, please buy bagged and quality coal.
– If dust comes out in bagged coal, immediately alert the place of purchase and replace it with a new one. If the marketer does not replace the new one, report the situation to the Provincial Directorate of Environment and Urbanization and to the Environmental Protection Directorates of Municipalities in the Metropolitan Municipality.
Pay Attention to Ash When Buying Coal
– Make sure that the ash in the coal is low.
– The higher the amount of ash in the coal, the higher the amount of base ash and fly ash resulting from combustion.
– When using high coal with ash for heating purposes, stoves, boilers and chimneys are more frequently clogged and need to be cleaned.
– As the amount of ash in the coal increases, the amount of particulate matter thrown out of the chimney increases. As the amount of particulate matter thrown out of the chimney increases, the amount of particulate matter in the atmosphere increases. Dust emission (PM) thrown from the chimney causes serious air pollution.
– Airborne PM10 and PM2.5 pollutants cause lung infection, worsening symptoms in people with heart and lung disease, and heart and lung disease if prolonged exposure to PM pollution.
Pay Attention To The Size When Buying Coal
– When purchasing coal, please pay attention to its size.
– Coal size should be between 18-150 mm in domestic and imported coal.
– If the size of the coal is small in the grill range, reduce the size of the small coals under the grill. Thus, coal becomes ashtray through the grill during combustion. Overcharged coal would be overpaid.
– In stoker combustion systems, coal size can be 10-18 mm. Coals of this size can only be used in stoker combustion systems.
– Oversized coals are from unprocessed coals. It contains a lot of sulfur, ash and moisture.
– It is not possible to burn large size coals evenly.
– Some coals crumble by losing moisture in their bodies over time. Never buy such coal.
– If the size of the coal you purchase is too small (powdered coal), you can ask for it to be replaced at the coal sales points. If there is a problem, you can apply to the Provincial Directorate of Environment and Urbanization and the Municipality.
Pay Attention to Sulfur When Buying Coal
– Never buy high sulfur coals. When sulfur in coal is burned, sulfur dioxide is formed.
– Sulfur dioxide causes serious air pollution. When we breathe sulfur dioxide air, it causes cough, chest tightness and lung disease.
– When sulfur dioxide concentration rises above a certain concentration in the air, it causes deaths.
– Sulfur dioxide causes acid rain in the air.
– Acid rain causes serious destruction on people, plants and things. Acid rain destroys historical buildings and artifacts.
– If you want to reduce acid rain and sulfur dioxide pollution, buy low sulfur and high calorie coal.
Pay Attention to the Inflatable Index When Buying Coal
– Coals with high index of swelling are coals suitable for coking. When such coals are used for heating, volatile substances (VOC) are released without being burnt at a certain temperature. The volatile volatiles become attached to the chimneys and cause the chimney to clog. With the blockage of the chimney, there is a chimney hill in the stove and boiler. Such coals are often fatal, especially in homes burned on stoves.
– In the imported and domestic coal, the swelling index cannot exceed 1 (maximum).
– When this type of coal is burned, the chimneys should be cleaned frequently.
– Coals with high swelling index should never be used for heating purposes.
Pay Attention to Volatile Matter (VOC) When Buying Coal
– Use coal with high calorie and low fly in stoves. The heat released while burning coal in the stove should remain in the room. Otherwise, you will lose more heat in the chimney.
– In conventional heating boilers, use both high calorie and volatile coals. High volatile coals burn with long flames; The flame that occurs during combustion keeps in contact with the water jackets for a longer period of time and causes the water to warm up.
– It is recommended that the amount of volatile matter in imported coal is between 12-29% on a dry basis.
