摘要

The boiler to produce thermal energy, superaquecedor of boiler, and method in a boiler producing thermal energy.A boiler and a method in a boiler (1) to produce heat energy, the method comprising: combustion or fuel and combustion air into the furnace (2) of the boiler, bounded by walls; receipt of thermal energy by a superaquecedor steam (15) placed in the furnace and aprede Comprising at least one surface of the heat exchanger (21).And the supply of a gas or a gas mixture in front of the surface of the heat exchanger to form a barrier layer (18), to protect the surface of the heat exchanger of the waste gas (19) developed for combustion.At least one supply device (17) is provided in or in the vicinity superaquecedor direct superaquecedor, to supply gas or gas mixture in front of the surface of the heat exchanger to form a barrier layer (18) to protect the surface of the heat exchanger D. The waste gases (19) in the boiler.In one example, a matrix device is provided in the supply area bounded by the superaquecedor.
