As the weather gradually becomes colder, various areas begin to heat, and some areas use coal for heating. However, there are many types of coal, so we need to understand what is used for heating. Coal is good? How much does a ton of residential heating coal cost? Regarding this question, many friends want to know the answer. Let’s find out quickly.
What kind of coal is good for heating?
Anthracite coal with high calorific value is more cost-effective and resistant to burning. Calorie is a measure of the calorific value of coal. The larger the calorific value, the better the coal. Use 5,000 to 6,000 kcal anthracite with a volatile content of 6-7. The calorific value of coal varies from place to place, so the price cannot be measured. Therefore, international regulations: standard coal is 7,000 kcal. There are two types of coal you can choose for home heating. One is lump coal, which is bituminous coal. It is easier to burn. When the fire is strong, you need to use coal, or anthracite, or better bituminous coal mixed with soil to press the stove to prevent it from burning too much. Quickly, this ensures that the temperature remains warm throughout the night. Sulfur is a harmful impurity in coal. Although it has no effect on the combustion itself, its content is too high, which can cause serious corrosion to equipment and environmental pollution. Therefore, the sulfur content of coal burned in power plants cannot be too high, and the general requirement is that the maximum cannot exceed 2.5.
How much does civil heating coal cost per ton?
The price of civil clean and environmentally friendly coal is about 500 yuan per ton. There are differences between regions due to different economic and consumption levels, but the price difference is small. Clean coal is coal that has been processed through desulfurization, denitrification and other processes. This coal significantly reduces pollution compared to ordinary coal. In recent years, rural areas in the northern region have strongly encouraged farmers to use environmentally friendly coal. In addition, if farmers purchase this environmentally friendly coal, they can receive corresponding subsidies. In some places, farmers buy it themselves, and the government then returns subsidies to the farmers. In some places, subsidies are directly subsidized by prices, cheap prices. When farmers purchase, they must first report to the village collective, and then someone will transport the goods to the door of the house. Farmers only need to pay the price after subsidies. According to different classifications of carbonization, they can be divided into peat, lignite (brown coal, black coal), bituminous coal (bituminous coal), anthracite and sub-coal (a type of lignite, which is a unique classification in Japan). Anthracite has the highest carbonization, while peat Lowest carbonation.
The price of heating coal has more than doubled in many places
On October 18, residents in Inner Mongolia, Gansu and other places reported on multiple online platforms that the price of heating coal has increased this winter. , coal prices in Gansu Province doubled year-on-year, and coal prices in Bayannur City, Inner Mongolia reached a maximum of three times the price in the same period last year. As coal supply exceeds demand, domestic coal prices have risen overall this year, driving up the price of heating coal. Ren Yanbo, secretary-general of the Civilian Clean Stoves Committee of the China Rural Energy Industry Association, said that rising coal prices are a nationwide phenomenon and there is currently no good solution. Traditional heating methods such as straw burning and firewood burning may appear in large numbers in rural areas this winter. A resident who lives in Bayannur City said that his family had just bought 4 tons of heating coal for this winter in the past two days, at a price of 2,000 yuan per ton. "Last year, the same coal was priced at 800 yuan per ton, and the lower quality coal was 600 yuan per ton. I am 50 years old, and I have never seen coal prices rise above 1,000 yuan before," the resident said.
What are the heating equipment?
Mainly include air conditioners, heaters, electric blankets, wall-mounted boilers, electric heaters and other heating equipment. The heat sources of different heating equipment are different, including burning fuel, electric heat, geothermal, solar energy, heat pumps, etc. Among them, air conditioners, electric blankets, electric heaters, etc. are all electric heat sources, while wall-mounted boilers, floor heating, radiators, etc. are fuel-burning type heat source. Floor heating is very common in northern households. Most newly developed communities have floor heating pipes laid directly. This heating method is very comfortable, hygienic and health-care. Installed on the ground, it can effectively save indoor space and will not affect the environment. When it comes to the overall aesthetics of a home, the key is to have many advantages such as high efficiency, energy saving, good thermal stability, low operating costs, long service life, and strong adaptability.
