Abstract

The preferred way of replacement anthracite and lean coal of Donetsk basin on six Thermal Power Plant (TTP) of Ukraine is import of coal with close characteristics. The surpluses of flame coal or gas flame coal produced within the country, should be used to replace the anthracite coal to the TPP of Ukraine. The estimated total capacity of units that need to be redesigned for the full replacement of anthracite and lean gas coal to the TPP of Ukraine is about 3.8 GW. However, complete substitution of anthracite and lean coal to flame coal or gas flame coal to the TPP of Ukraine requires comprehensive economic calculations. It is shown that necessary pay attention for the following activities for use flame coal or gas flame coal instead of anthracite or lean coal: reconstruction of system for coal drying and shredding; implementation of activities and equipment for new anti-explosion and anti-fire systems for use more fire risk fuel; replacement or reconstruction of burners; testing new maximum load and the working load range of steam boiler for use flame coal or gas flame coal; definition potential problems with and finding ash conditions deposits on the heating surfaces. Most important for change fuel project with replacement anthracite coal and Lean coal for use flame coal or gas flame coal is system for coal drying and shredding. Although it is possible use hot air for drying flame coal or gas flame coal but preferably better used system for coal drying and shredding with concentration oxygen in drying agent not more 16 %. For reduce the oxygen concentration in the system for coal drying and shredding using need exhaust gas additive. Taking into consideration the poor state of the atmospheric air in the cities it is advisable to save the work of municipal CHP (combined heat and power) of Ukraine with use natural gas.
