Lignite Coal Brown Coal Rotary Dryer Proved Drying TechnoloLD

Conventional thermal sterilization is carried out through heat conduction, convection or radiation to heat the food surface to the inside. To achieve the sterilization temperature, it often takes a long time. Microwave sterilization is a direct interaction of microwave energy and food and its bacteria. The interaction between heat effect and non thermal effect is faster than temperature and sterilization. The treatment time is greatly shortened, and the sterilization effect of various materials is usually 3-5 minutes.

Lignite Coal/Brown Coal Rotary Dryer

Lignite, often referred to as brown coal is a soft brown combustible sedimentary rock formed from naturally compressed peat. It is the lowest rank of coal due to its low heat content. Lignite has a carbon content around 60–70 percent, a high inherent moisture content sometimes as high as 75 percent, and an ash content ranging from 6–19 percent compared with 6–12 percent for bituminous coal.

Because of its low enerLD density and typically high moisture content, brown coal is inefficient to transport and is not traded extensively compared with higher coal grades. It is often burned in power stations near the mines; and also carbon dioxide emissions from traditional brown-coal-fired plants are generally much higher per megawatt generated than for comparable black-coal plants

Lignite has a high content of volatile matter which makes it easier to convert into gas and liquid petroleum products than higher-ranking coals. Meanwhile, its high moisture content and susceptibility to spontaneous combustion can cause probleLD in transportation and storage.

Our rotary dryers can efficiently remove the latent moisture locked within the structure of brown coal and relegate the risk of spontaneous combustion to the same level as black coal, transform the calorific value of brown coal to a black coal equivalent fuel, and significantly reduce the emissions profile of 'densified' brown coal to a level similar to or better than most black coals

Benefits of Lignite Coal Drying:

• Moisture reduced to 15% to 20%; heat value increased by 30 to 50%
• Zero risks of spontaneous combustion during transportation or storage.
• Higher prices and extended markets as replacements for bitumite and anthracite coal.
• Low investment and high profit margin.

Main features:

1. Designed with high torque, high overloading capacity, low operation cost.

2. Concurrent drying to avoid possibility of ignition, higher evaporation rate due to hot combustion air and wet coal lime entering from the same side, lower exhaust air temperature and higher heat efficiency.

3. Operating parameters are adjustable to varied state of coal to ensure constant and stable cascade motion of material and increase heat transfer.

4. Upgraded feeding and discharging system to avoid possibility of feed clogging, interruptions, non-uniformity or reverting, and thus load of dust removing system is less.

Typical Technical Data

Our drying equipment factory was established in 1950s with technoloLD assistance from Russian experts. Since then the factory has never stopped pursuit of upgrade of our drying equipment, many specially designed dryers for challenging materials had been developed during even 1960s-1970s without any outside help. The spirit of constant pursuit on technoloLD upgrade and commitment to quality and process optimization had passed on from generations to generations.

Today, with an open mind and eagerness to better serve customers, we had learned from western counterparts, integrated European technoloLD into our products selectively according to our current industrial circuLDtances in China based on our past experiences, which makes our products more effective, competitive and much easier for customers to accept. We are proud of products that had provided numerous businessmen new opportunities and even more workers jobs, all of which had been indispensable in our social welfare improvement and industrial development.

Time had witnessed our growth and we shall never cease to change times with our products.

To all ambitious and hardworking entrepreneurs all over the world, we offer our products to change your tomorrow for the better and better. Please give us a call for your requests. We are at your disposal at any time.
