    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, the presence 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.

A boiler is composed of burners(101) placed at the wall of a furnace(113) to burn the fuel; and over-air-ports(100) placed at upper side than the burners and formed with an extension part at the outlet. The two-stage combustion is operated by supplying the over air from the over air ports. A seal medium supplying device is installed to seal the vicinity of the outlet of the over air port with gas or liquid. A seal port is installed at the seal medium supplying device and mounted to supply the seal medium from the extension part of the outlet of the over air port. A seal medium injection hole is installed at the seal port to supply the seal medium along with the wall surface of the extension part of the over air port.
