摘要：

Pulverized coal-fired boilers consume a large amount of oil for ignition or flame stability during the start-up and low turn-down ratio operation. Reducing the oil consumption is very important and urgent. Based on the analyses on two important factors on the stability of pulverized coal combustion, namely the rate of primary air heating, the oxygen concentration in primary air, a new burner has been designed to increase the local oxygen concentration and the temperature of the primary air. The burner combines the merits of traditional high temperature air combustion (HTAC) and oxygen enriched combustion (OEC) technology. Moreover, it has excellent fuel flexibility,. It is expected the new burner can be alternative technology other than the existing oil-saving gun and plasma gun technologies.
