In the past two decades, the oxy-fuel combustion of pulverized coal has been extensively developed, leading to the completion of several large industrial pilot oxy-fuel plants worldwide. Various types of oxy-fuel burners have been designed and tested in large-scale pilot plants as key components of oxy-fuel combustion. These burners face …
today, there normally exists a combustible coal/ air mixture in the burner lines and pulverizer equipment. Hence there is the continual danger of fires and, under certain conditions, explosions. Proper design and operation of the pulverized coal burners protects the pulverizing system from ignition from the furnace fire.
1.6.1 Pulverized coal combustion. In pulverized coal combustion (PCC), dust burners are used to feed coal into the combustion chamber, where flame core zones of the combustion chamber having a temperature range between 1450°C and 1600°C are present. To attain the required efficiency, pulverized coal is given a swirling motion around the flame ...
One of the principal ways of finding a compromise in tangentially fired pulverized coal (PC) boilers, which constitute the majority of the utility boilers, is through tilting the burners. ...
