On 20 August 2009, Techinservice company staff launched a lime kiln of Alexandrovsky brick-making plant. Fuel used for the kiln is anthracite coal. Conversion of lime kiln from natural gas to anthracite coal resulted in improvement of technical and economical characteristics. 

As a result of lime kiln modernization, the following standards of performance were achieved:

- standard capacity – 40 tons of lime per day;
- maximum capacity -  65 tons of lime per day;
- activity of the resulting СаО – 90%;
- fully automatic functioning mode.


Reference: anthracite coal is an alternative kind of hard fuel.
One gigacalorie of heat, produced out of natural gas, is three times more expensive than the one produced by means of anthracite coal burning.
