Simmer Coal Dryer
1. Characteristics and Geographical distribution of Simmer Coal
Simmer coal, also called wood coal, is the lowest degree of coalification coal mining. Simmer the degree of coalification of coal just above coal slime coal, is a kind of dark brown between peat and bituminous coal, matte inferior coal. Because of the lignite are rich in volatile, so it is easy to burn and smoke. On the profile can clearly see the trace of the original wood. Coal and simmer with projects were the salient features: high moisture (water content between 32 ~ 42%), high volatile flux (typically between 40 ~ 50%), low calorific value (heating value is about 23.0-27.2 million kilojoules/kg (5500-6500 kcal/kg) general average calorific value under 3000 calories), low density, low ash melting point. Containing humic acid soluble in alkali. Carbon content 60% ~ 77%, density of about 1.1 to 1.2. No glue layer thickness. More brownish or brown-black, relative density 1.2 ~ 1.45. Based on the above reasons hard to widely used as industrial power coal, lignite so simmer the economic value of coal can not get the biggest embodiment. Under the present situation of global energy increasingly nervous, simmer the economic value of coal is important for the world's energy industry, dry up quality lignite technology is the development and application of lignite and the basis of large-scale industrial application conditions.
2. Structure of Simmer Coal
Simmer coal dryer's main components are: crusher, conveyor, feeder, heat source equipment, rotary dryers, a feeder, and the wind system, dust removal equipment, temperature control device, electrical system, etc
3. Features of Our Designed Simmer Coal
Our drying equipment mature technology, stable performance, low consumption, high efficiency, environmental protection is the preferred brand lignite drying drying industry.
1). The drying cost minimization. Simmer coal dryer heat preservation measures, to reduce heat loss. Using a low-cost coal as a heat source of fuel, reduce fuel expenses. Lignite drying equipment to the automation to reduce labor costs.
2). Dry maximize production safety. Simmer coal drying equipment automation flameproof explosion-proof device, put an end to production accidents. Site construction by skillful and experienced technical construction personnel, to ensure stable operation of equipment. One year free warranty, life-long maintenance, to ensure that you have no trouble back at home.
3). The drying quality of the finished product. Simmer coal dryer USES the three layers of subsidence structure, reduce dust pollution of material. High temperature rapid process to reduce the loss of organic elements in the material. Online water monitoring, fuzzy control, make the material water evenly after drying.
4). Large intensity of drying. Simmer coal drying equipment to water up to 8000 kg per hour, continuous production.
5). High drying efficiency. Simmer coal dryer using high temperature rapid drying process, the utilization rate of hot air temperature thermal efficiency is increased by 40% than the ordinary low temperature drying methods, thermal efficiency up to 90% of the heat source system, make comprehensive thermal efficiency as high as 73%. Part of the drying into the head end to continue heating, hot air by the end of the reducing heat loss.
