Способ зажигания и стабилизации горения водоугольного топлива в форкамере, включающий тепловую обработку распыленной форсункой струи топлива, отличающийся тем, что тепловую обработку распыленной струи топлива осуществляют у устья струи потоком термической плазмы, генерируемой электродуговым нагревателем газа, в предварительно разогретой потоком плазмы до 500-750°С форкамере, при этом длину потока плазмы формируют исходя из условия
Figure 00000001

где l - длина потока плазмы;
d - характерный размер сечения распыленной струи топлива у устья струи;
D - двойное расстояние от начала потока плазмы до оси струи топлива;
α - характерный угол раскрытия распыленной струи топлива;
β - угол наклона оси потока плазмы к оси распыленной струи топлива;
S - расстояние от начала потока плазмы до плоскости, перпендикулярной оси струи топлива в месте установки форсунки.A method of ignition and stabilization of combustion of coal-water fuel in a prechamber, including heat treatment of a sprayed fuel jet with a nozzle, characterized in that the heat treatment of the sprayed fuel jet is carried out at the mouth of the jet by a stream of thermal plasma generated by an electric arc gas heater in a preheated plasma stream to 500-750 ° With a prechamber, the plasma flow length is formed based on the condition
Figure 00000001

where l is the plasma flow length;
d is the characteristic cross-sectional size of the sprayed fuel jet at the mouth of the jet;
D is the double distance from the beginning of the plasma flow to the axis of the fuel jet;
α is the characteristic opening angle of the atomized jet of fuel;
β is the angle of inclination of the axis of the plasma flow to the axis of the atomized jet of fuel;
S is the distance from the beginning of the plasma flow to the plane perpendicular to the axis of the fuel jet at the nozzle installation site.
