摘要

The method involves using three fuel nozzles (16) and forming a hollow flame by the arrangement and number of fuel nozzles. The quantity of the liquid fuel promoted by a fuel pump (14) is changed with the changing of the number of revolutions of the fuel pump. A part of the supplied fuel is branched by a pressure relief pipeline of the fuel line (2) of the fuel pump.
