Lignite, peat difference, how to choose the lignite drying machine to create more value
Coal can be used to generate electricity, of course, lignite is also possible, low cost, safety, energy saving and environment protection, so the lignite drying machine is your ideal choice for coal project investment.
Coal is a mixture of complex composed of inorganic and organic matter, lignite, peat is two kinds of different kinds of coal coal.
The main difference between lignite, peat:
1 is the formation of different plants. Lignite is a large tree body formation; peat moss, sphagnum, ice is Carex and other aquatic plants formed.
2 different carbonization degree. Lignite carbonization degree higher than peat; lignite calorific value than peat peat is high, low calorific value of coal.
3 different applications. Lignite is mainly usedfor power plant fuel, but also can be used as chemical raw material, catalyst supports, adsorbents, sewage purification and recovery of metal etc..
There are generally two types: (1) the earthy lignite (brown coal), loose texture and soft; (2) dark brown coal (lignite), dense texture hard. 
Can be directly used as a household fuel, industrial fuel and power source of fuel, but also can be used as the raw material, low temperature dry distillation gasification.
Peat is used as organic compound fertilizer and soilless cultivation substrate.
Brown coal, lignite is a low rank coal, quality will vary with the mineral condition change, but it is easy to ignite, burning completely, low sulfur characteristics often make thermal power plant fuel.
Lignite resources distribution:
China's lignite volume was only 2118 tons, compared with the world of lignite resources accounted for the total amount of coal resource in the world of 1/3, the ratio is very low, about the total amount of resources the country below 1/20, mainly distributed in eastern Inner Mongolia, 
Eastern Yunnan, northeast and Southern China also have a small amount of.
Its moisture, volatile components of high (>40%), free humic acid. Weathering fragmentation in the air, burning low (about 270 degrees). Storage for more than two months is easy to spontaneous combustion, stacking height should not exceed two meters.
And the value of lignite drying method:
As a result of lignite is a degree of coalification lowest mineral coal. Its moisture, volatile components of high (>40%), free humic acid, easily weathering fragmentation in the air, burning low (about 270 degrees). Storage for more than two months is easy to spontaneous combustion, stacking height should not exceed two meters, the decision is not suitable for transport of lignite. Therefore lignite market is limited, with air as the lignite drying machine drying medium into convective heating mode and source line under the action of the draught fan, the exchange of lignite and high humidity pressure into the drying machine for mass transfer, heat transfer. The operation mode to stir scattered wet lignite pulverized lignite slowly vibration moves forward and discharging drying drum, complete drying of lignite process. The dried lignite is mainly used for power plant fuel, but also can be used as chemical raw material, catalyst carrier, adsorbent, wastewater purification and recovery of metal etc.. Coking after can be prepared as lignite briquette for cooking and heating; it is used as the source of the activated carbon, used for water treatment, recovery of gold and extraction of iodine. Nature is very extensive lignite drying machine for investment prospects, 
Shanghai Daiwo mining machinery combined drying machine production for many years of practical experience, we summarized the investment in the earlier stage of lignite drying machine equipment, as follows:
Technology and function 1, drying machine
If customers do not understand technology and function of lignite drying machine, can not be normal operation of lignite drying machine, make the dryer equipment can not achieve the desired effect.
The concrete scheme of process 2, drying machine
The purchase of lignite drying machine, only the combination of the local situation of scientific and reasonable, can formulate the process scheme of lignite drying machine, in the process of lignite drying machine requirements, in order to meet the requirement of the corresponding process.
3 lignite drying machine can get economic benefits
Customer investment lignite drying machine, estimate of lignite drying machine can bring much economic benefit, for customers to bring economic benefits is greater, for production equipment manufacturers is the biggest benefit.
