FIELD: power industry.
SUBSTANCE: boiler plant includes air supply path with forced-draft fan, high-viscous fuel supply line, for example fuel oil from its holding tank containing fuel oil supply devices to fuel pump, filtering assembly, fuel heater installed before fuel pump, spraying device, combustion chamber with gas discharge path equipped with chimney with confuser, and the plant control unit. Besides, boiler plant includes a tank for low-viscous liquid fuel, for example diesel oil, which is connected through additional fuel pipeline to fuel pump. Chimney outlet is connected by means of gas balance pipe equipped with control gate valve to air supply path inlet; at that, the latter is equipped with control gate valve.
EFFECT: providing the start-up of boiler plant irrespective of ambient temperature and viscosity of heavy fuel and enlarging the operating life of spraying guns of atomisers.
