[0002] Coal pyrolysis furnaces (coke ovens) currently on the market mostly adopt batch-type coking. When working with coal, it is not possible to continuously and automatically adjust the amount of coal injected into the carbonization chamber of the coal pyrolysis furnace according to the coalification in the carbonization chamber of the coal pyrolysis furnace and the coke output of the coal pyrolysis furnace

Embodiment Construction
[0028] The specific embodiment of the coal-into-furnace adjustment bin of the coal pyrolysis furnace of the present invention is mainly introduced in detail in the third section of the third part below.
[0029] Part 1 Furnace Coal Proportion and Preparation
[0030] The coal pyrolysis furnace involved in the present invention can obtain cokes of different grades according to different proportions of coals fed into the furnace.
[0031] The steps are as follows: 1) 5 kinds of different coals are selected, which are respectively gas coal, fat coal, coking coal, one-third coking coal and lean coal. 2) Gas coal 20%~40%; fat coal 10%~20%; coking coal 10%~20%; one-third coking coal 15%~30%; lean coal 10%~15%, first mix and then sieve Broken until the broken particles reach below 5mm to form coal into the furnace. Of course, the coal pyrolysis furnace of the present invention is equally applicable to coal into the furnace with other proportions and particle sizes, and does not cons...

The invention discloses a coal as fired regulation bunker for a coal pyrolyzing furnace. The coal as fired regulation bunker is arranged at the upper part of a coking chamber of the coal pyrolyzing furnace and is positioned at the lower part of a preheating device. The coal as fired regulation bunker is characterized by comprising a small coal bunker, a coal bunker loading level gage, a coal bunker charging level gage, a small coal bunker charging path and a small coal bunker charging valve, wherein the upper side of the small coal bunker is connected with a preheater of the preheating device; the coal bunker loading level gage and the coal bunker charging level gage are respectively arranged at the top and the bottom of the small coal bunker; the small coal bunker charging path is connected to the bottom of the small coal bunker through the small coal bunker charging valve; and the small coal bunker charging path leads to the coking chamber of the coal pyrolyzing furnace. The coal as fired regulation bunker can be used for continuously regulating the quantity of coal as fired injected to the coking chamber of the coal pyrolyzing furnace according to the coal carbonization in the coking chamber of the coal pyrolyzing furnace and the coke yield situation of the coal pyrolyzing furnace.
Description
technical field [0001] The invention relates to an adjusting device, in particular to an adjusting bin for charging furnace coal into a carbonization chamber of a coal pyrolysis furnace. Background technique [0002] Coal pyrolysis furnaces (coking ovens) currently on the market mostly adopt batch-type coking. When working with coal, the amount of coal injected into the coal pyrolysis furnace cannot be continuously and automatically adjusted according to the coalification in the carbonization chamber of the coal pyrolysis furnace and the coking situation of the coal pyrolysis furnace. [0003] This prompts the inventors to think and develop a regulating chamber capable of continuously and automatically regulating the amount of coal added into the furnace in the carbonization chamber. Contents of the invention [0004] The invention provides a furnace-input coal adjustment bin of a coal pyrolysis furnace. The amount of coal injected into the furnace in the carbonization c...
