**The object of the capital** improvement in this work is the boiler units of thermal power plants that burn slagging Irsha-Borodinsky coals. The subject of the capital improvement is the technological characteristics of the burner process in firebox.  **The purpose** of the work is to increase the improve fuel combustion efficiency, conduct measures for impingement attack of water economizer and air heater, change the old tubular collector to new one for operational reliability and reconstruct the liquid slag removal boiler to solid one for emission abatement NOx. **Objectives of the capital improvement**: 1) Thermal calculation of the boiler in order todemonstrate improvement of the quality of work before and aftercapital improvement. 2) Calculation of technical-economic indicators of the boiler before and after capital improvement.
 * Bachelor thesis on the topic «Capital improvement of the Krasnoyarsk CHPP-1». **

 **Practical significance of the work**: 1) Calculated data on the heat efficiency characteristics of the heating surfaces of BBW-320-140-PT2 boilers of the Krasnoyarsk CHPP-1. 2) Development of a new thermal scheme of the Krasnoyarsk CHPP-1 after capital improvement.
