Abstract
The invention discloses a determination method for slag block of a gasification furnace. The determination method comprises the following steps of (1) cleaning any channel of a startup burner channel, an igniter burner channel or flame detection channel of the gasification furnace; (2) throwing a metal ball or a metal oxide ball in the gasification furnace from any channel with slag removed, if the metal ball or the metal oxide ball is discharged form a slag port of the gasification furnace, the slag port is determined as unblocked without influencing restarting a furnace, and the gasification furnace can be arranged to restart. The determination method has the beneficial effects that time can be controlled within 24 hours from stopping the furnace to restarting the furnace, maintenance time is greatly shortened, and loss caused by stopping the furnace can be greatly reduced.
Description
Technical field
The present invention relates to stifled slag decision method, relate in particular to the stifled slag decision method of vapourizing furnace cinder notch.
Background technology
SHELL dry coal powder gasification technology is to be researched and developed successfully the seventies in last century by Holland, and be successfully applied to the cogeneration project, the mid-90 is introduced China, has had 23 cover vapourizing furnaces to settle China at present, and the introduction of this technology has extremely far-reaching influence to China's Coal Chemical Industry industry.This vapourizing furnace is to be raw material with coal dust and oxygen, is mainly used to produce chemical industry material synthesis gas and industrial fuel gas, has that single stove throughput is big, gasification efficiency is high, a remarkable advantage such as safety and environmental protection, in the field of business have significantly strive advantage and promotion potential unexpectedly.
Vapourizing furnace in process of production, adjustment owing to coal reason and daily technological operation, the vapourizing furnace cinder notch has stifled slag situation and takes place, at present the stifled slag of vapourizing furnace can only be with reference to this instrument measurement value of gasifier slag mouth pressure reduction, can not macroscopic test under the situation of not opening manhole, by blowing out to cinder notch cleaning find, be not all to need to stop to handle at every turn, reason is to be out to find behind the vapourizing furnace manhole that cinder notch does not block, and just moment has arrived jumping car value.Blowing out inspection for causing because of the stifled slag of vapourizing furnace needs 5 day time at least, has influenced production greatly, has caused enormous economic loss.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, provide a kind of and can judge stifled scoriform condition fast, thus the stifled slag decision method of a kind of vapourizing furnace that has shortened shutdown period greatly.
Technical scheme of the present invention is:
A kind of vapourizing furnace blocks up the slag decision method, and it may further comprise the steps:
(1) any one passage in cleaning gasifier to start working burner channel, igniter burner passage or the fire inspection passage;
(2) the passage of any one behind removing slag Metal Ball or metal oxide spheres are put in the vapourizing furnace, if described Metal Ball or metal oxide spheres are discharged from the cinder notch of vapourizing furnace, can judge that then cinder notch does not block, not influence again and drive, arrange vapourizing furnace to drive again.
The invention has the beneficial effects as follows: drive from stopping to handle, can control the soonest at 24 hours, shortened the repair time greatly, greatly reduce the loss of stopping and causing.
Description of drawings
Accompanying drawing is the structural representation of existing vapourizing furnace.

(1) any one passage in cleaning gasifier to start working burner channel 1, igniter burner passage 2 or the fire inspection passage 3; (2) passage of any one behind removing slag is that the iron ball of 45mm is put into the vapourizing furnace with diameter, and described iron ball is discharged from the cinder notch 4 of vapourizing furnace, judges that cinder notch does not block, and does not influence again and drives, and arranges vapourizing furnace to drive again.
Be 10 hours stoppage time.
(1) any one passage in cleaning gasifier to start working burner channel 1, igniter burner passage 2 or the fire inspection passage 3; (2) passage of any one behind removing slag is that the aluminium sesquioxide ball of 50mm is put into the vapourizing furnace with diameter, described aluminium sesquioxide ball is discharged from the cinder notch 4 of vapourizing furnace, judge that cinder notch does not block, do not influence again and drive, arrange vapourizing furnace to drive again.
Be 15 hours stoppage time.
(1) any one passage in cleaning gasifier to start working burner channel 1, igniter burner passage 2 or the fire inspection passage 3; (2) passage of any one behind removing slag is that the aluminium sesquioxide ball of 55mm is put into the vapourizing furnace with diameter, and described aluminium sesquioxide ball is discharged from the cinder notch 4 of vapourizing furnace, judges that cinder notch blocks, and opens manhole, and vapourizing furnace is carried out the cinder notch cleaning.
Be 5 days stoppage time.
Claims (2)
1. a vapourizing furnace blocks up the slag decision method, it is characterized in that it may further comprise the steps:
(1) any one passage in cleaning gasifier to start working burner channel, igniter burner passage or the fire inspection passage;
(2) the passage of any one behind removing slag Metal Ball or metal oxide spheres are put in the vapourizing furnace, if described Metal Ball or metal oxide spheres are discharged from the cinder notch of vapourizing furnace, can judge that then cinder notch does not block, not influence again and drive, can arrange vapourizing furnace to drive again.
2. vapourizing furnace according to claim 1 blocks up the slag decision method, and it is characterized in that: the diameter of described Metal Ball or metal oxide spheres is 45mm-55mm.
