With its own development and growth and business expansion needs, the opportunity to participate in large-scale bidding activities more and more, which fully reflects the visibility and influence of the industry, to the sound development of the corporate image, lignite dryer bidding activities have demonstrated their due strength and corporate style. Professional lignite dryer manufacturers lignite dryer project bidding activities how to deal with it? Public tender in its openness and breadth of competition has a large advantage, but the public tender also has some drawbacks, for example, due to the large number of bidders, generally takes longer, it takes the cost is also larger for procurement smaller the subject of the tender, open tender is often not worth the candle; addition, some projects are highly professional, qualified potential bidders to undertake fewer or need in a relatively short period of time to complete the task of procurement should not be used open tender. Invited to tender to a certain extent, make up for these shortcomings, while relatively full play to the advantages of tender. Depth dehydration processing the system by way of thermal drying of coal products to effectively improve its calorific value indicators and reservoir shipment performance, so that the indicators meet the requirements of commodity thermal coal, has obvious economic, environmental and social benefits. The Dongding lignite dryer technical features (1) dry lignite not get damp absorbent: dried lignite larger physical and chemical changes in the pores collapse, the cross-linking reaction and tar migration of pores form a seal, the result lignite change more and more hydrophobic, and also be able to observe the hardening of the lignite, which also led to the formation of the rigid structure of the lignite. (2) dry lignite volatiles are effectively protected: the humidity content uploaded wet media, no volatile release conditions; (3) a high degree of automation, simple manipulation: a high degree of system integration, and with automatic intelligent monitoring system , real-time monitoring of the parameters of the hot stove furnace, the entrance to the dryer, the dryer outlet and induced draft fan entrance of the main parts of the temperature, pressure, flame, smoke oxygen, the system runs automatically control and adjust the parameters for automatic acquisition, fault alarm and security interlock protection. (4) Energy efficient: dry heat loss (drying) machine, high thermal efficiency; heat source coal burnout rate of pulverized coal up to 99% of the hot stove, the effect of heat transfer efficiency than traditional coal-fired hot air furnace section Coal 30 --- 50%; lignite powder produced by the drying process can be used as a fuel, which greatly reduces the cost of fuel. (5) Safety: seamless wind phenomenon unique sealing structure to discharge completely solve the sealing difficulty to achieve full oxidation negative pressure operation to eliminate the possibility of lignite combustion and explosion, safe and reliable operation.
