Abstract
The invention is in the field of power engineering and can be used in thermal power plants to fire up boiler units without using fuel oil from a cool state to a working regime. The aim is to eliminate the need for fuel oil for firing coal-dust torches, thereby enhancing the efficiency of the boiler firing process. The proposed technology for firing industrial boilers without fuel oil is based on plasma fuel ignition techniques. A successful result is achieved when the coal-dust torch is fired by generating a stream of low-temperature plasma using plasma generators installed in the muffles of the lower-tier coal-dust burners, feeding the coal-dust mixture through the low-temperature plasma stream and igniting it and by subsequent switching off of plasma generators. In addition, depending on the type of boiler unit, pulverisation techniques and fuel characteristics, the quantity (n) of coal-dust burners equipped with plasma generators and muffles can be in the range of n = 1 m, where m is the quantity of burners on the lower tier.

Empty or gas vents are mounted in conjunction with the main coal ditches, or are installed in addition to them. For example, the П-39 unit has 12 basic dust removal units with a capacity of 8 t / hour and 8 fuel oil hours / 1.3 hours. When sold in fuel oil and coal, high-reactive liquid fuels are ignited. When fuel oil is burned, a significant amount of heat is emitted, a quick heat of coal dust.
