It is developed on basis of the theory of combustion and is proved to be very successful in operation. Those coals, which are hard to burn, can be fired successfuly with this method of combustion. P-c burners can be easily retrofitted to this new method of combustion. The firing of such hard to burn coals can be burnt with great stability and high burn-out efficiency. Therefore, this new method of p-c firing is considered very prospective in China. It can be used widely in power stations. Its advantages in combustion and economy of operation are eminent. Patent has been granted to it by the Patent Office of China and it got good evaluation in power industry. In this article, the principle of its design and its performance arc briefly discussed.展开更多
