Swirling Burners with a Higher Bush Ratio for Increasing Economic Efficiency of Pulverized Fuel Burning.

Consideration is given to burners with a higher bush ratio. Their use helps to increase the stability of ignition of low-reaction fuels and of the economic efficiency of burning them. It is noted that economic efficiency of the TP-230-2 boiler equipped with such burners is considerably higher (q//4 equals 0. 1 divided by 2. 5%) when burning pulverized fuel than is the case with the boilers with conventional burners. Tests of the burner with increased bush ratio and the feeding of the drying agent snail of the secondary air are presented. This burner has been installed in a TPP-210 boiler.
