METHOD AND APPARATUS FOR STARTING THE BOILER OF A SOLID-FUEL FIRED POWER PLANT AND ENSURING THE BURNING PROCESS OF THE FUEL

摘要

This invention concerns a method and apparatus for starting the boiler of a solid-fuel fired power plant and for ensuring the burning process of the fuel. According to the invention, the main fuel of the boiler is ignited by entering an auxiliary fuel stream gasified and ignited with a plasma torch (1). Efficient mixing and safe ignition of the main fuel with the auxiliary fuel is ensured by means of turbulent feed of the auxiliary fuel and a nozzle (12) through which the auxiliary fuel is entered into the main fuel stream.
