COAL-WATER POWER PLANT Russian patent published in 2014 - IPC F23K1/02 

FIELD: electricity.

SUBSTANCE: in coal-water fuel coal nanopowder is mixed with water in the necessary stoichiometric ratio, a pneumatic nozzle supplies fuel into a reaction channel, when entering which flame of a plasma generator fully decomposed water into oxygen and hydrogen, partially decomposes ash products of coal into oxygen and appropriate elements, further methane and carbonic acid gas are produced, the plasma generator is switched off, since heat release of these reactions exceeds heat of water and ash products decomposition. After the zone of methane formation, air is introduced into the reactive channel in the necessary amount, and methane, being oxidised, releases additional heat. The reaction channel first has the shape of the expanding pipe, which in the right part changes into a receiving channel arranged in the form of a horseshoe, the left part of which with the help of a filter also serves as a collector of remains of combustion of ash products of coal, and the right part is a collector of carbonic acid. Reaction and receiving channels are covered by pipes of larger diameter, and coolant is supplied into a gap between pipes, preferably, water. After passage through the reaction channel, coolant is sent into a thermal circuit (heat exchanger, turbine, refrigerator, water treatment, pump). The power generator generates energy.

EFFECT: invention makes it possible to increase efficiency of reaction heat conversion into electric energy.
