Coke-saving precast optimization control system for coke put into furnace

Abstract

The invention relates to a coke-saving precast optimization control system for coke put into a furnace, which comprises a coke input system, a conveyor belt system, a blast furnace and a precast optimization control module, wherein a modifying agent control unit is arranged between the coke input system and the conveyor belt system; a heating system is arranged between the conveyor belt system and the blast furnace; and the precast optimization control module is connected with the coke input system, the conveyor belt system, the heating system, the modifying agent control unit and the blast furnace through a signal line. The thermal efficiency of the coke-saving precast optimization control system for the coke put into the furnace is greatly improved, and the coal-saving rate is 30-50 percent. By adopting the control system, the emission is reduced, and the emission loads of dust, slag, SO2 and the like are respectively and greatly reduced, thus, the neighboring environment is purified.

Description

technical field [0001] The invention relates to a combustion energy-saving control system, in particular to an optimal control system for prefabrication of coke in a furnace for saving coke. Background technique [0002] Coal is the main energy source in our country. 84% of the coal in our country is used for direct combustion. Due to the relative backwardness of coal-fired equipment and combustion technology, it has brought about two major problems: low combustion efficiency and serious environmental pollution. Taking industrial boilers as an example, there are more than 520,000 coal-fired industrial boilers in my country, and the annual coal consumption accounts for 35% of the total coal production, but the average boiler efficiency is only 60%, which is 20 percentage points lower than the 80% efficiency of advanced countries. Above, this item alone wastes nearly 100 million tons of raw coal every year, mainly because most industrial boilers are chain furnaces. The thermal...

Problems solved by technology

The combustion process of the bed-burning furnace has certain requirements on the coal type and particle size. In addition, the new large-scale boiler itself is consuming metal and mineral resources, which is also a disguised damage to the environment.

Therefore, under the existing conditions, how to improve the combustion efficiency of small boilers, reduce pollutant emissions, and design a new energy-saving automatic control system for blast furnaces is what the country really advocates. At present, there is no such automatic control system on the market.
