METHOD FOR INTENSIFYING COMBUSTION PROCESS OF TPP SOLID LOW-REACTIVE FUEL Russian patent published in 2011 - IPC F23B90/00 C10L9/10 B82B1/00 

FIELD: power industry.

SUBSTANCE: method for intensifying the combustion process of TPP solid low-reactivity fuel involves preparation of pulverised-coal mixture of low-reactivity fuel with air and nanoaddition; pulverised-coal mixture is subject to ultrasonic treatment immediately prior to supply to burners, and then to ignition and burning in the boiler. As nanoadditions there used are astralines - multi-layer fulleroide nanoparticles or Taunit - carbon nanomaterial. Nanoadditions are introduced to pulverised-coal mixture in the form of homoeopathic doses as per weight of solid fuel of 0.01 - 0.02%. The method results in increase of response rate of ignition and combustion of fuel mixture; besides, at combined burning of low-reactivity coal and fuel oil in the steam boiler furnace the method leads to reduction of unburnt carbon, nitrogen and sulphur oxides emissions, and therefore, to reduction of corrosion of heating surface and to improvement of reliability of power equipment; increase in combustion efficiency of pulverised-fuel mixture of low-reactivity fuel with air and nanoaddition owing to avoiding the agglomeration of components. The effect is achieved due to intensification method of combustion process of TPP solid low-reactivity fuel, which involves preparation of pulverised-coal mixture of low-reactivity fuel with air and nanoaddition, ultrasonic treatment, ignition and its burning in the boiler.

EFFECT: increasing combustion efficiency of low-reactivity solid fuel.
