For indoor heating at home, is it better to use anthracite or bituminous coal.

Anthracite is the preferred choice for home heating.

Anthracite filter materialAnthracite filter media is the best filter material commonly used at present. Anthracite filter material ore sources mainly come from the two major coalfields of Jincheng and Yangcheng in Shanxi. It is versatile and has a wide range of adaptations.

Anthracite filter media can be used for domestic drinking water and industrial production water, as well as ordinary fast filters of various pool types. Anthracite filter material double-layer and three-layer filters, various sewage filters, water purification mechanical filters and chemical, metallurgy, thermoelectric, pharmaceutical, papermaking, printing and dyeing, etc.

There are several types of coal, such as lignite, bituminous coal, anthracite, semi-anthracite, etc. There are three commonly used types of lignite, bituminous coal and anthracite in Yunnan. Different types of coal, their composition and quality are different, and the calorific value is also different.

The heat emitted by the combustion of fuel per unit weight is called calorific value, and the coal with a calorific value of 7000 kcal per kilogram is artificially stipulated as the standard coal, and the coal consumption is converted according to this standard.

1) Lignite: mostly lumpy, black-brown, dark luster and loose texture; It contains about 40% volatile matter, low ignition point, easy to ignite, fast ignition when burning, large flame and black smoke; The carbon content and calorific value are low (due to the different coal grades in the production area, the calorific value varies greatly), the combustion time is short, and coal needs to be added frequently.

2) Bituminous coal: generally granular, small lumps, and powdery, mostly black and shiny, fine texture, containing more than 30% volatile matter, the ignition point is not too high, and it is easy to ignite; The carbon content and calorific value are high, the fire is fast when burning, the flame is long, there is a lot of black smoke, and the combustion time is long; Most bituminous coal is viscous and prone to slag formation when burned.

3) Anthracite: There are two kinds of powdered and small lumps, which are black and shiny with metallic luster. There are few impurities, the texture is tight, and the fixed carbon content is high, up to more than 80%; The volatile content is low, below 10%, the ignition point is high, and it is not easy to ignite; However, the calorific value is high, the fire is slow when it is just burned, it is relatively large after the fire comes up, the fire power is strong, the flame is short, the smoke is less, the combustion time is long, the cohesion is weak, and it is not easy to slag when burning.

It should be mixed with an appropriate amount of coal and clay to reduce the fire intensity.

In October 1989, the National Bureau of Standards issued the "National Standard for Coal Classification in China" (GB5751-86), which divided coal into 14 categories according to six classification indicators, including dry ash-free volatile matter VDAF, adhesion index G, maximum thickness of colloidal layer Y, Oya expansion B, coal sample transmittance P, constant humidity and ash-free high calorific value QGR of coal, and MAF. That is, lignite, long-flame coal, non-sticky coal, weakly sticky coal, 1 2 medium sticky coal, gas coal, gas fertilizer coal, 1 3 coking coal, fertile coal, coking coal, lean coal, lean coal, lean coal and anthracite.

Anthracite is better for home heating, anthracite is safe and environmentally friendly, has less smoke and good combustion effect. Clean coal-fired + environmentally friendly stoves to help get a smoke-free winter and have a good use experience. The cost of heating is lower. In some areas**, there will be a subsidy for the purchase of anthracite.

Anthracite, good for health.

The bituminous coal that my family used last winter can't close the door when the smoke dies, so how can I keep warm, and then I will change to a smokeless one! Hope it helps.

No smoke, smoke is not ventilated and easy to suffocate.

Anthracite ......Otherwise, the house is full of smoke.

Summary. Hello, glad to answer for you. You can use bituminous coal or anthracite, but the cost of using anthracite is too high, and there are generally more bituminous coals, but you have to choose high quality!

Hello, glad to answer for you. You can use bituminous coal to sell potatoes or use anthracite for those who are at a loss, but the cost of using anthracite is too high, and there are generally more bituminous coals, but you must choose high-quality!

Hello, glad to answer for you. It is best to use anthracite for stool bright cherry, but the cost is too high, generally more honeycomb coal, bituminous coal can also be jujube bush, but it is necessary to operate cautiously to seal the oven and seal the thousands of keys in the world, otherwise the flue-cured tobacco will be downgraded.

Hello, glad to answer for you. Anthracite (English name anthracite), commonly known as white coal or red coal. It is the coal with the largest degree of coalification.

Anthracite coal has high fixed carbon content, low volatile yield, high density, high hardness, high ignition point, and no smoke when burning. The black is hard and piny, with a metallic luster. It is not stained by grease friction, and the fracture is shell-shaped, and the flame is short and less smoke when burning.

No coke. Generally, the carbon content is more than 90%, and the volatile matter is less than 10%. No gum layer thickness.

The calorific value is about 6000-6500 kcal kg. Sometimes the most volatile content is called semi-anthracite; The very small one is called mountain to high anthracite.

Anthracite is good, less smoke and safe, full combustion, good heating effect, clean and environmentally friendly, in line with national environmental protection policies.

Clean coal + supporting stove heating Clean briquette heating is relatively low compared with other clean energy heating methods, the first guarantee is relatively stable, clean coal is flammable, high calorific value, long fire sealing time, burn-resistant and coal-saving, low consumption, no need to add coal frequently, time-saving and labor-saving, better use, greatly reducing the amount of coal used, more economical and energy-saving. Clean coal burning is low sulfur, low ash, low volatile, and more fully combusted, which can effectively reduce the emission of pollutants such as carbon monoxide, sulfur dioxide and nitrogen oxides. After combustion, less smoke and dust is generated, which can effectively reduce the pollution to the atmosphere, thereby improving the living environment.

Coal combustion is basically low-altitude direct discharge, and the combustion products are easily inhaled by the human body. The sulfur content of clean coal is low, there is no black smoke and no peculiar smell when burning, and the harmful substances produced are less, and the harm to the human body is very low, which can effectively reduce the phenomenon of gas poisoning in winter.

Hello, dear, I am happy to answer for you: which is a good answer for home electric heating or coal heating Dear Hello Coal-fired heating stove is good Personally recommend household coal-fired heating stove. The heating effect of the household coal-fired heating stove is very good, and it adopts the step-by-step time-sharing input method to control the heating group, and the heating group can be randomly put in or stop working according to the load change, which significantly reduces the impact on the power grid.

At the same time, it can also manually start and stop the number of heating sections, so that it is convenient for users to adjust the electric power of the boiler by themselves. It is cost-effective to burn briquettes and electricity, and of course it is cost-effective to burn briquettes (if environmental protection is not considered). One kilogram of briquettes can produce about 6,000 to 8,000 kcal after combustion, and according to the minimum calculation of 6,000 kcal, one kilowatt-hour of electricity can produce about 860 kcal (100% heat conversion rate, the actual maximum heat conversion rate is 90%, that is, 770 kcal).

A meal of briquettes is about 800 yuan, and one kilogram of briquettes is also yuan, and one kilowatt-hour of electricity is ** yuan, which means that you spend one kilogram of briquettes for money, which is about equal to 8 kilowatt-hours of electricity. So briquettes are cost-effective.

Anthracite is better than smokeless. In appearance, anthracite also has the same metallic luster as bituminous coal.

1. The amount of smoke is different: the smoke of anthracite is less, and the smoke of bituminous coal is larger.

2. The combustion time is different: anthracite is the longest lasting coal in coal. The continuous combustion level of bituminous coal is not long, and it can only rank in the middle of coal, and the continuous combustion time is higher than that of lignite and lower than that of anthracite.

3. The water content is different: the water content of anthracite is lower than that of bituminous coal, and the smoke that comes out is less, and the bituminous coal feels foggy after combustion.

Honeycomb coal is made of anthracite as the main raw material, because part of the loess and white ash is added when making, and the calorific value is certainly not as high as anthracite.

As for **, depending on how it is compared, the ** of anthracite lump coal is higher than that of honeycomb coal, and the ** of raw coal (face coal) is lower than that of honeycomb coal.

This year, the coal is so high, what is the most economical heating.

Burn straw, branches, and wood for warmth. Many farmers have fruit trees planted in their homes, and the fruit trees prune a large number of branches every year, and farmers can install pot stoves in their homes to burn the branches to keep warm. Even if there are no fruit trees, every house has straw, and although it is forbidden to burn straw in the ground, it is not a problem to burn it in a pot stove.

If you use a stove with a countertop, you can also increase the heat dissipation area and improve the heating efficiency. 2. Install a sun canopy for heating. The sun shelter is a very common heating facility in the Northeast, and the installation is also very simple, you only need to install a bracket similar to a vegetable greenhouse on the sunny side, and then spread a plastic sheet on the bracket, which can effectively increase the temperature in the house when there is sunlight.

And in the summer, you can directly remove the plastic sheeting, which will not affect the ventilation in summer. Of course, if the economic conditions allow, you can also install a sun room, use glass instead of plastic sheeting, so that the light transmittance is better, and the heating effect is better, but according to the cost is relatively high, and the ventilation in summer is more difficult, the sun room is more suitable for the northeast and coastal areas with lower summer temperatures. And the sun canopy is suitable for various areas.

3. The fire kang takes the judgment shirt. The kang is found in many areas in the north, especially in the northeast, and the whole house is warmed by burning a fire under the kang, which can burn branches and straws, and does not increase the heating cost of farmers. 4. Solar heating.

In recent years, the development of solar heating is also very fast, more advanced equipment can not only store the heat energy of the day, and even store a week's heat energy, but because solar heating is affected by the weather, it is generally necessary to match gas rush furnace, coal-fired stove, electric heating and other auxiliary facilities, compared with the first several heating methods, the equipment cost is relatively high, and the cost of later use is also higher, but it is relatively environmentally friendly, and it is worth trying some rural families with relatively high incomes.

The coal burned for home heating is anthracite.

The quality indicators of coal used for power generation are:

Volatile matter. It is the primary indicator to determine the fire characteristics of coal. The higher the volatile content, the easier it is to catch fire.

According to the boiler design requirements, the value of volatile matter for coal supply should not change too much, otherwise it will affect the normal operation of the boiler. For example, after the original design uses low volatile coal and changes to high volatile coal, the furnace may be shut down due to the burning of the injector due to the fact that the center of the flame is close to the outlet of the injector; If the original design uses high volatile coal and changes to low volatile coal, the combustion will be incomplete due to too late ignition, and even cause a flameout accident. Therefore, when supplying coal, it is necessary to try to according to the original design of volatile coal type or similar coal type**.

Ash content. The ash content will reduce the flame propagation speed, delay the ignition time, unstable combustion, and reduce the furnace temperature.

Moisture content. Moisture is one of the harmful substances in the combustion process, it absorbs a lot of heat during the combustion process, and the impact on combustion is much greater than ash.

Calorific value. The calorific value is an important basis for boiler design. Because the pulverized coal in the power plant has strong adaptability to the type of coal, as long as the calorific value of the coal is roughly consistent with the design requirements of the boiler.

Ash melting point. Because the core temperature of the furnace flame of the pulverized coal furnace is more than 1500, at such a high temperature, the coal ash is mostly in a soft or fluid state.

Sulfur content of coal. Sulfur is a harmful impurity in coal, although it has no effect on the combustion itself, but its content is too high, and the corrosion of equipment and environmental pollution are quite serious. Therefore, the sulfur content of coal used in power plants should not be too high, and the general requirement should not be exceeded.

Anthracite is the best, with less pollution and more heat.

Air pollution needs to be controlled to avoid incomplete combustion.

Shanxi or Inner Mongolia low-bituminous coal will do.
