Use the coal rod machine make the coal rod gas making should pay attention's important point's:
the strength of coal rod gasification is lower comprise to high quality gasification level ,if want to improve the high coal rod's gasification level ,first ,must make put a energy at the management of raw material and the making of coal rod ,at the technology of gasification and the gas making equipment should have a correspond reform,we think ,should pay more attention to the follow aspect:
as much as possible make a good and stable guarantee of coal origin.
2.south of the yangtze river rine season is humidity, the coal which is staking at the open-air
The water content is as high as to 10 percent,so it can't put the binder,so should have the enough coal shed,can stock a more than half month consumption's dry coal .
3.the quality of the coal rod ,is a premise which in influence the gasification technology and consumption.in order to make the high quality coal rod ., must grasp the link that broken ,retting ,binder's make ,water concent control ,the diameter of coal rod ,etc,should periodic inspection the strength of coal rod ,the quality rate should achieve to more than 90 percent .
4, the wet coal rod gas required to maintain a higher dry carbonization layer and suitable furnace surface temperature, therefore, to be on the gasification process of coal rod is adjusted accordingly, to maintain appropriate furnace surface temperature, sufficient dry distillation layer, a slightly higher bottom temperature, appropriate steam and air, gasification process follows the blow ( steam ) and ( time ) short, blowing ( steam ) weak ( time ) chief principle, maintain adequate fire layer, and carbon and ash should be adjusted.
5, the gas making process of time plus carbon will make the furnace condition worsening, therefore, must attach great importance to the coal rod production management and coal rods and equipment maintenance, should be equipped with adequate coal rod transport, ensure the coal rod b |
