The pressure of the primary air is 15–20 kPa, and the amount is 30–60% of the maximum total combustion air. Secondary air is supplied through several secondary air ports in one or two levels located 2–5 m from the bottom. The amount of secondary air can be regulated from 10% to 50% of the maximum total combustion air.

BR-1833 - A Comparison of Fluid-Bed Technologies for

Sep 01, 2016 · 1. Introduction. With the implement of the updated national emission regulation (NER) of China, more and more power plants are under the pressure of NO x removal. Circulating fluidized bed (CFB) boilers have the innate advantage of low NO x emission due to its lower combustion temperature and more reducing solids than that in pulverized coal (PC) boilers .
