Abstract

Provided are a solid-fuel burner (60) suitable for controlling a flame formed by combustion of fuel ejected from the burner (60) and controlling the temperature distribution in a furnace, a combustion device using the solid-fuel burner (60), and a method of operating the combustion device. Gas outlet nozzles (81, 82) and a restriction (obstacle)(19), which is placed on the downstream of the gas outlet nozzles (81, 82), are arranged in a fuel nozzle (10), and a relatively larger amount of gas is ejected from one (81) of the gas outlet nozzles. This provides a circumferential variation in the distribution of fuel concentration. Further, thepresence of the restriction (obstacle)(19) on the downstream side increases a difference in the fuel concentration. The flame forming position can be changed by providing the fuel concentration with such a circumferential difference. Regulating the flow rate of gas flowing in the gas outlet nozzles (81, 82) allows the temperature of combusted gas at a furnace outlet, the temperature of heat transfer tubes arranged on a furnace wall surface, the temperature of fluid flowing in the flow transfer tubes, the temperature of heat transfer tubes arranged in the furnace and in a gas duct on the downstream side of the furnace, and the temperature of gas flowing in the heat transfer tubes to be controlled to constant levels.
