PLANT FOR PREPARATION OF SOLID FUEL FOR COMBUSTION Russian patent published in 2016 - IPC F23K1/00 F23G7/00 F23B99/00 

FIELD: energy.

SUBSTANCE: invention relates to heat engineering and can be used for preparation of solid fuel for combustion in heat power plants (HPP). Plant for preparation of solid fuel for combustion contains technologically interconnected: a raw fuel channel, a raw fuel bin, a dewatering device connected with a hot air channel, a fuel store bin, a grinding device, a fuel feed channel connected with the fuel store bin. Solid fuel used for combustion is dried oily sludge from chemical treatment of water, herewith the channel and the bin of raw fuel represent a channel and a bin of wet oily sludge from chemical treatment of water (CTW) in the form of a mixture of separated oil products and waste sludge from CTW after treatment of waste waters of heat power plants from oil products, a the fuel store bin is a dried oily sludge from CTW store bin. Solid fuel used for combustion can be dried oily sludge from CTW with the moisture content of 3-4 % and the particle size of not more than 1.5 mm.

EFFECT: invention simplifies the process scheme of fuel economy of HPP on solid fuel due to a simplified design of the plant for preparation of solid fuel for combustion, expands the range and reduces the cost of solid fuel, thus reducing the cost of produced electric and heat energy owing to recycling of chemical water treatment oily sludge, herewith using the HPP wastes - separated oil products and used CTW sludge after treatment of waste waters of heat power plants from oil products.
