The Creation of a Low-Capacity Boiler Plant on Coal-Enrichment Waste

Abstract

A serious problem for coal production is the environmentally friendly utilization of coal mining waste and coal enrichment. In different countries, the best specialists in this field are trying to find the solution of this problem. In the United States, France and China, the technology of preparation and burning of water-coal suspensions (WCS) for the utilization of fine-dispersed wastes of coal enrichment and coal slurries has been successfully used. A boiler with a thermal capacity of 0.63 MW with a vortex combustion system efficiently operating on fuel from coal waste was designed, manufactured and tested. The results of the operation of the boiler on this fuel showed its high efficiency (the efficiency is 83-86%) with the level of harmful emissions in the flue gases below the permissible values
