conveying of pulverized coals, is one of the best contemporary coal gasifiion technologies[1,2]. Handling and storage of pulverized coal are known to produce wellknown problems like bridging, channeling, fluctuating flow rate or even blocking in process equipment and storage as the tendency of agglomeration causing by the strong
10/05/2013 · Fig 1 Typical flow sheet of pulverized coal injection in blast furnace. The process of coal injection. The PCI process is based on the simple concept of carrying the finely ground (pulverized) dried coal by a conveying gas (normally nitrogen) to the BF where it is distributed to different tuyeres and injected through a lance in the blow pipe.
Normally, the traditional coal process systems use ball mills to pulverize coal. Flue gases are used as drying and conveying medium in the pulverizing process. Pulverized coal cyclones of TsP2 type Тяжмаш Pulverized coal cyclones are designed for airandcoal mixture purifiion in coal pulverization systems in manufacturing hopper.

The design parameters of the 750MW pulverizedcoalfired power plant as discussed in Chapter 2 provide a net plant efficiency of 45% at rated output conditions. However, it is of utmost importance that good performance is sustained over a wide operating range of the power plant.
Using the fluidization properties of pulverized coal could make densephase pneumatic conveying of pulverized coal easier. In order to maintain stable conveying, it is important to seek the optimum flow pattern of pulverized coal in the feeding hopper. As shown in, fluidizing gas was injected into the feeding hopper through gas distributor.
