Abstract
The invention discloses a coal combustion improver and belongs to the technical filed of combustion. The coal combustion improver mainly comprises the following components and materials in weight ratio: 18 to 28 wt percent of calcium chloride, 8 to 18 wt percent of activated carbon, 5 to 15 percent of chromium trioxide, 20 to 30 wt percent of sodium carbonate, 16 to 25 wt percent of bis(pentamethylcyclopentadienyl)eisen and 8 to 16 wt percent of dolomite dust. The invention further discloses a preparation method of the coal combustion improver. The coal combustion improver provided by the invention remarkably increases the temperatures of inner flame and middle flame, improves the combustion efficiency within a combustion area, and obviously reduces flue gas discharge, the ringelman emittance of the flue gas is smaller than 1, and the coal saving rate can reach 17 to 26 percent.
Description
Technical field
The present invention relates to a kind of coal combustion-promoting agents and preparation method, is specifically a kind of for promoting coal combustion-promoting agents and the preparation method of coal burning quality, minimizing pollutant emission, belongs to field of combustion technology.
Background technology
Heat power plant is in daily production process, and a large amount of coal that unavoidably need to burn for improving coal combustion efficiency, reduce pollutant emission and reducing the phenomenons such as coking, conventionally suitably adds some ignition dopes and improves coal burning in fire coal.Combustion-supporting agent for fuel coal of the prior art, most of formula constituents are single, function singleness, be difficult to mix, and need minute sample to add and cause service routine loaded down with trivial details in use procedure, cannot reach expection combustion-supporting effect.
Summary of the invention
The technical problem that the present invention solves is to overcome above-mentioned defect, provide a kind of formula reasonable, mix, the obvious solid-state coal combustion-promoting agents of combustion-supporting effect and preparation method.
In order to solve the problems of the technologies described above, solid-state coal combustion-promoting agents provided by the invention, by the material of following component and weight ratio, made:
Calcium chloride: 18-28wt%, gac: 8-18wt%, chromium trioxide: 5-15wt%, sodium carbonate: 20-30wt%, full methyl ferrocene: 16-25wt%, ground dolomite: 8-16wt%.
As improvement, described solid-state coal combustion-promoting agents is made by the material of following component and weight ratio: calcium chloride: 23wt%, gac: 14wt%, chromium trioxide: 6wt%, sodium carbonate: 25wt%, full methyl ferrocene: 20wt%, ground dolomite: 12wt%.
The present invention also provides a kind of preparation method of solid-state coal combustion-promoting agents, comprises the following steps:
1), calcium chloride, chromium trioxide, sodium carbonate, the full methyl ferrocene of determining deal are dropped into and are stirred in stirrer after, standing 5-10 hour;
2), in step 1) compound in add again gac, the ground dolomite of determining deal to stir and at least stir 10 minutes in stirrer, obtain coal combustion-promoting agents.
As improvement, described step 1) time of repose in is 8 hours.
Beneficial effect of the present invention is: (1), coal combustion-promoting agents of the present invention have obviously improved the temperature of flame internal flame, middle flame, have improved the efficiency of combustion in combustion zone; (2), coal combustion-promoting agents cost of the present invention is lower, easily stir; (3), the discharge that can obviously lower flue gas, flue gas lingemann blackness < 1; (4), after use coal combustion-promoting agents of the present invention, coal-fired coal saving rate can reach 17-26%.
