Q:Types of coal and how

It should be noted that the G value is greater than 100 of the coal, especially coal mine average G or several samples were above 100, generally can not measure Y value determined for coal or gas coal class.Also stipulated in China's coal classification standard, the G value is greater than 85 of the coal, if not measured Y, also available Oaxaca expansion degree B value (%) to determine the boundaries of coal and gas and other types of coal, namely Vdaf<28% coal, tentative b value of >150% for coal to Vdaf>28%; coal, provisional b value of >220% for coal (when the value of Vdaf <37% (Vdaf) or gas when the value of >37%). When there is a contradiction between the classification of coal according to the b value and the type of coal classified according to the Y value, the coal class determined by the Y value shall prevail. Thus in determining the new classification of strong caking coal brand, can only measure the Y value and temporarily B value.

Q:What is the role of coal

5) living coal: the number of living coal is also large, accounting for about 20%. of fuel coal6 metallurgical power coal: Metallurgical power coal is mainly used for sintering and blast furnace coal injection, the amount of less than 1% of the coal used for power

Q:One thousand watt hour electricity to fold the standard coal

1 kwh of electricity =1 kWh14300398*0.1229=1757518.9142 kilograms of standard coal =1757.5189142 tons of standard coal14300398*0.4040=5777360.792 kilograms of standard coal =5777.360792 tons of standard coalWhat is your calculation of coal use.

Q:Activated carbon rain has been poured into the useful

Look at the components of activated carbon depends on the pore size of the adsorption of harmful gases, harmful gas molecules with different amount of different particle size are different, the activated carbon gap in 0.45-2 nm can absorb formaldehyde and other toxic gases, the coconut shell charcoal is the first choice of activated carbon adsorption odor and stupid pollution gas, spherical microporous activated carbon is the ideal carbon adsorption of formaldehyde. Recommend the purchase of coconut shell activated carbon and gas phase spherical microporous activated carbon mixed into a comprehensive adsorption products. Not necessarily coconut shell is the best, and harmful gas molecules to match the aperture.4, the production of activated carbon dust process, must crush the raw material to remove dust, or dust too much, cleanliness is poor, it will cause pollution to the human body and the goods on the market, in order to reduce the cost of poor quality of activated carbon, no postprocessing, large dust, multi use dark bags, small charcoal bag hands up dirty, use will cause two pollution dirty items. Recommend the selection of small carbon bag is a white breathable non-woven bag, feel no dust is not dirty products.5, the bubble will be a handful of activated carbon into the water, because the water molecules and the pore structure of the water will gradually immersed in the activated charcoal, forcing the pores in air, resulting in a series of very small bubbles, pulls out a tiny bubbles in the water line, will be issued at the same time the slightest sound of bubbles, activated carbon this phenomenon is the better the performance of intense. Longer time.

Q:The difference between raw coal and fuel coal

Fuel coal is a part of the process that has gone through the water vapor and is not easy to burn

Q:What kind of pesticide chili pepper

Increase the application of phosphorus and potassium fertilizer, reasonable irrigation, timely removal of old, diseased leaves and fruit. Can be used in the initial stage of the latest domestic and international medicine [super] 56%] 100% of chlorothalonil, or 68% times a cream of zinc and manganese dioxide liquid spray of 800 times, or the effect of the 38% kinds of cream copper ester ester of the effect of 800 times! At the same time were: 80% conventional agents such as M-45, 75%, 65% Daktarin zineb, every 7 ~ 10 day spray 1 times, 3 times later.

Q:The main application value of coal and its impact on China's economy and the world

The use of coal is very extensive, according to the purpose of its use for two main purposes: (1) power coal, (2) coking coal.The main use of power coal in china:Steam coal1) coal for power generation: more than 1/3 of coal in China is used to generate electricity, and the average power consumption is 370g/ (kW / h). The power plant uses the calorific value of coal to convert heat energy into electrical energy. 2) steam locomotive coal: accounts for about 2% of the power coal, the average coal consumption of the boiler is 100kg/ (10000 tons / km). 3) coal for building materials: accounts for more than 10% of the power coal, with the largest amount of cement, followed by glass, brick, tile, etc.. 4 general industrial boiler coal: in addition to the thermal power plant and large heating boiler, the general enterprise and the heating of the industrial boiler model, large quantity and scattered, coal accounts for about 30% of the coal. 5) living with coal: the number of living coal is also large, accounting for about 20% of fuel coal. 6 metallurgical power coal: Metallurgical power coal is mainly used for sintering and blast furnace coal injection, the amount of less than 1% of the coal used for power.

Q:What are the types of coal

Bituminous coal: generally granular and small shape, there is powder, black and shiny, delicate texture, containing more than 30% volatile, ignition temperature is not too high, is easy to ignite; carbon content and calorific value of burning high, fast ignition, long flame, there are a lot of black smoke, burning a long time; most of coal are sticky, easy slagging combustion.

Q:White melon seeds produced by the mechanism of carbon why taste

Mechanism charcoal is made of sawdust, wood residue, peanut shell and straw. Because of easy combustion, high thermal efficiency, long combustion time, is currently the most commonly used barbecue carbon. However, due to the processing in order to shape, often before the addition of binder, the combustion will produce harmful gases

Q:Airlines are able what? Where do you need it? How much price ah? (unit price)

Aviation coal is aviation kerosene, basically be used at aviation turbine engine fuel, each big airline, aviation industry is sure to need
