摘要： An air nozzle arrangement for a fluidized bed boiler, comprising an air feed pipe and an air nozzle which limit an air feed duct configured to supply air to the furnace of the fluidized bed boiler. The air nozzle arrangement comprises a surface configured to guide coarse material along said surface. At least part of said surface is thermally insulated from the air nozzle and/or the air feed pipe. Furthermore, at least part of said surface is configured to protect at least part of said air nozzle and/or air feed pipe. Thus, the temperature of said surface is configured to be high when the fluidized bed boiler is in operation, whereby the solidification of molten material of the fluidized bed in the air nozzle arrangement is reduced.

摘要： A thermal device comprising some heat exchanger pipe of a flow duct for gases in the flow duct. The pipe comprises a first section which further comprises a second section. The second section of the heat exchanger pipe comprises an inner pipe for transferring heat transfer medium and for recovering heat into the heat transfer medium; an outer pipe that radially encloses said part of the inner pipe; and a medium layer placed between the outer pipe and the part of the inner pipe. The second section of the heat exchanger pipe extends in a straight line or bends less than 90 degrees. Furthermore, the first section is insulated in its entirety, or non-insulated in the vicinity of other heat recovery surfaces only. A wall of the device comprises a protrusion that makes the flow duct for gases narrower. Said first section of the heat exchanger pipe extends from said protrusion. The use of the device in such a way that the temperature of the heat transfer medium flowing in the inner pipe is at least 500°C, and/or in such a way that the temperature of the outer surface of the outer pipe is higher than 600°C, and/or in such a way that means for feeding an auxiliary agent are used for feeding an auxiliary agent to the thermal device. Furthermore, a method for heating a heat transfer medium, in which method said thermal device is used.
