The advanced coal drying equipment is mainly represented by those technical parameters, which are simply classified as low drying cost, large increase in coal calorific value, environmental protection and low consumption during equipment operation, and completely solve environmental problems.
Heat source configuration for coal drying
Nowadays, many customers are more concerned about the coal drying project than the funding problem. But the choice of heat source is electricity or coal? While electric drying coal is environmentally friendly and environmentally friendly, its cost has greatly reduced the economic benefits of coal drying. Therefore, many will be discouraged.How to solve? At present, Zhengzhou Dingli mainly supplies tumble dryers equipped with gas hot blast stoves, steam tube type drum equipment, and coal-fired hot blast stove equipment to solve the problem of coal ban and environmental protection.
Dedusting configuration for coal drying
The traditional coal drying is a single-machine treatment for tail gas treatment, that is, a cyclone dust collector. However, in the current form, the cyclone dust removal effect has been seriously unable to pass the EIA, and the upgrade configuration, that is, the wet and dry multi-stage dust removal system, ensures the EIA. However, the cost of coal drying naturally increases. Therefore, the energy-saving dryer adopted by Zhengzhou Dingli has carried out the necessary technical treatment for this problem to solve the problem of exhaust gas pollution and cost increase.
Targeted technical treatment of coal drying
Different coals have different characteristics. For example, coal slime is easy to agglomerate, paste wall, peat humic acid is relatively high, lignite has low ignition point and is brittle, so it cannot be applied to all coals with a tumble dryer. Therefore, the advanced nature is also manifested in professionalism.
