Definitions
- the invention relates to the field of energy technological processing of coal, in particular to the production of thermal energy from coal and high-calorie solid fuel (coke) for metallurgy, energy and other industries.
- the supply of heat to the fluidized bed is ensured by an intermediate heat carrier, the role of which is formed in the coke process.
- the recirculated part of the coke is heated in the coke heater due to is the combustion of pyrolysis gas generated during the carbonization of coal.
- the main product of this method is fine-grained coke (particle size 0-3 mm). Steam-gas products of thermal decomposition of coal undergo condensation with the release of tar and pyrolysis gas.
- SUBSTITUTE SHEET (RULE 26) environmental hazard technology due to toxicity and carcinogenic activity of a number of substances (phenols, polyaromatic hydrocarbons, etc.) contained in the products of thermal decomposition of coal.
- a known method of producing metallurgical medium-temperature coke (RU 22857515 according to class ClO B49 / 10 from 07.29.2005). The method involves the production of coke by thermo-oxidative treatment of coal in a fluidized bed, and coal with a fractional composition of 0-15 mm is used as a coal layer, and air is supplied through a coal layer at a temperature of 800-900 0 C.
- a device for processing solid fuel is known, which is a layer apparatus of a shaft type, made combined from the upper, middle and lower zones.
- the upper belt consists of a loading hatch, a gas outlet pipe, a water seal and an electrothermal device.
- the middle belt consists of a cylindrical body and a water jacket, and the lower belt is made in the form of a truncated cone and consists of a discharge device, a grate, a device for supplying air and / or cooling gas and thermoelectric sensors.
- this boiler unit is designed to produce only thermal energy with minimal mechanical underburning of solid fuel.
- Another disadvantage is the need for disposal of ash and slag waste, which leads to environmental pollution.
- the objective of the invention is to increase the efficiency and simplify the method of thermal processing of coal, as well as improving environmental safety.
- the technical result of the invention is the production of high-calorie solid fuel and thermal energy from coal.
- the specified technical result is achieved by the fact that as the feedstock, coal fractions of 0-35 mm are used, and coal processing is carried out sequentially in two sections of a fluidized bed separated by a barrier, and in the first section thermo-oxidative treatment is carried out at a temperature of 650-800 0 C with air supply and in the second section, the resulting coke is cooled by supplying water vapor or chilled flue gases.
- the device for implementing the method is made in the form of a boiler unit, in which the furnace consists of two sections of a fluidized bed, separated
- FIG. 1 schematically shows a device for implementing a method of processing coal. It contains a boiler unit 1 with a furnace, divided by a barrier 2 into two sections of the fluidized bed 3 and 4. Subsections 5 are used to supply air to section 3, and channels 6 are used to supply a cooling agent.
- Coal in section 3 is fed through a feeder 7.
- a method of processing coal into high-calorie technological solid fuel is as follows.
- a fluidized (boiling) layer of coal which, depending on the prescribed mode, determined by the ratio of air blast to coal consumption, has a temperature of 650 to 800 0 C
- pre-crushed coal of fraction 0-35 mm is continuously fed by feeder 7.
- crushing of large fractions of coal as a result of thermal shock when it enters the fluidized bed with high temperature occurs.
- Larger coal particles, heated to the temperature of the layer and moving horizontally along the first section of the fluidized bed 3 pass through the stages of drying and pyrolysis and partial gasification, Air into the first section 3 is supplied through independently adjustable subsections 5 along the length of the fluidized bed.
- SUBSTITUTE SHEET (RULE 26) sections does not exceed 10 seconds, which leads to high specific productivity of the installation.
- Finely dispersed coal, vapor-gas products of thermal decomposition of coal, as well as coke gasification products are partially burned in the first section of the fluidized bed 3, ensuring its working temperature, are removed from the fluidized bed and burn out in the superlayer space by supplying a secondary air blast.
- the resulting combustion products and the emitting surface of the fluidized bed, as well as heated gases from the second section of the boiling gas 4 give heat to the heating surfaces of the boiler unit 1 to generate thermal energy in the form of hot water or water vapor.
- Heat from the combustion products and from the radiating surface of the fluidized bed is transferred to the heating surfaces of the boiler unit 1 to generate thermal energy - hot water or water vapor with specified parameters.
- Table 1 shows the technical performance of the modernized KBTC-20 boiler unit, in tables 2-3 the characteristics of the used coal fraction 0-35mm grade 2B grade "Berezovsky-1" Kansko-Achinsk coal basin and the product obtained from it - high-calorie solid fuel - coke .
- the proposed method and device for its implementation allows you to process coal fraction 0-35 mm into high-calorie solid fuel with the simultaneous production of thermal energy.
