From Introduction This bulletin, therefore, presents both bad and the good features of pulverized-coal plants and gives recommendations for safe installation and operation. Consequently, in the preparation of this bulletin much of the material on explosions in plants is based on the results of tests at the experimental mine and in the laboratory dust gallery.
The system of blast furnace pulverized coal has been widely used in Electric Power, Steel and Metallurgical industry etc. In the whole system, the preparation of pulverized coal is the most important step. Common mill cant satisfy the needs of pulverized coal due to its high demand and big capacity.
Oct 30, 2000 Pyrolysis and ignition characteristics of pulverized coals were examined under similar burning conditions to those of industrial burners. In the early stage, fine particles less than 37 m were mainly pyrolyzed by convective heat transfer from surrounding gas.
A flame image recognition system FIRES has been developed, which calculates the estimated value of NOX emission from pulverized coal combustion by two dimensional measurements and digital image processing of flame forms. This system can be effectively applied to low NOX and high efficiency combustion is industrial and utility boilers. ITV cameras observe the flame image in the vicinity of ...
