The use of coal rod machine coal rod gas should be the focus of attention points
Coal gasification intensity ratio quality rod block gas of low level, in order to improve the coal rod gasification level, must first in the management of raw materials and coal rod production efforts, in the gasification process and gas equipment also should make corresponding transformation, we think, should pay attention to the following aspects.
1, as far as possible to guarantee a better and more stable source of coal.
In 2, southern rainy humid, stacked in the open in the moisture content of coal is often as high as 10%, which would make the binder cannot be added, therefore should be equipped with sufficient area of coal, should be able to have half a month or more dry coal quantity amount.
3, coal rod quality, is the influence of gasification process and the consumption of the premise. For the preparation of high quality coal rod, must grasp the coal rod broken, preparation of retting, adhesive preparation, moisture control, coal rod diameter and other aspects, the coal rod strength should be regular testing, qualified strength to achieve the rate above 90%.
In 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.
In 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 both in quality and quantity to meet the need of g |
