Abstract
The invention relates to a proportioning method of coal as fired for a coal pyrolysis furnace. The coal as fired is selected from five different coals, namely gas coal, fat coal, coking coal, one third coking coal and lean coal, wherein the gas coal accounts for 20-40%, the fat coal accounts for 10-20%, the coking coal accounts for 10-20%, the one third coking coal accounts for 15-30%, and the lean coal accounts for 10-15%, and different proportions can be carried out according to quality of the obtained coke. The proportioning method of the coal as fired for the coal pyrolysis furnace greatly increases a coal source of the coking coal, and addition quantity of weakly caking coal reaches up to more than 40%.
Description
Technical field
The invention belongs to a kind of coke making process, be specifically related to a kind of matching method that enters the stove coal of coal heat decomposition stove.
Background technology
Coking major part in the market is intermittent type coking, in the proportioning that enters the stove coal to the weakly caking coal kind amount of allocating into seldom, so the coking cost is high.
Summary of the invention
Technical problem to be solved by this invention provides a kind of matching method that enters the stove coal of coal heat decomposition stove, can according to the different coke that obtain, carry out different proportionings.
Technical scheme of the present invention: a kind of matching method that enters the stove coal of coal heat decomposition stove, it is characterized in that it comprises the steps: 1, selects 5 kinds of different coals, they are respectively bottle coal, rich coal, coking coal, 1/3rd coking coal, lean coal.2, bottle coal 20%～40% wherein; Rich coal 10%～20%; Coking coal 10%～20%; / 3rd coking coal 15%～30%; Lean coal 10%～15% carries out proportioning according to the difference of the quality that obtains coke.
The present invention compared with prior art has following beneficial effect: a kind of matching method that enters the stove coal of coal heat decomposition stove has increased the coal source of coking coal greatly, and the weakly caking coal amount of allocating into is reached more than 40%, has reduced the cost of coking coal, has fine competitive power in market.
Concrete embodiment
The matching method that enters the stove coal of 1 one kinds of coal heat decomposition stoves of embodiment, this enters the stove coal and selects 5 kinds of different coals, and they are respectively bottle coal, rich coal, coking coal, 1/3rd coking coal, lean coal, and wherein bottle coal 40%, rich coal 20%, coking coal 10%; / 3rd coking coal 15%, lean coal 15%.
The matching method that enters the stove coal of 2 one kinds of coal heat decomposition stoves of embodiment, this enters the stove coal and selects 5 kinds of different coals, and they are respectively bottle coal, rich coal, coking coal, 1/3rd coking coal, lean coal, and wherein bottle coal 20%, rich coal 20%, coking coal 20%; / 3rd coking coal 25%, lean coal 15%.
The matching method that enters the stove coal of 3 one kinds of coal heat decomposition stoves of embodiment, this enters the stove coal and selects 5 kinds of different coals, and they are respectively bottle coal, rich coal, coking coal, 1/3rd coking coal, lean coal, and wherein bottle coal 30%, rich coal 15%, coking coal 15%; / 3rd coking coal 30%, lean coal 10%.
Claims (1)
1. the matching method that enters the stove coal of a coal heat decomposition stove is characterized in that it comprises the steps:
(1) select 5 kinds of different coals, they are respectively bottle coal, rich coal, coking coal, 1/3rd coking coal, lean coal.
(2) bottle coal 20%～40% wherein; Rich coal 10%～20%; Coking coal 10%～20%; / 3rd coking coal 15%～30%; Lean coal 10%～15% carries out proportioning according to the difference of the quality that obtains coke.
