Annotation to the article «Increasing thermal efficiency half-surface heating surfaces steam boilers in combustion slowing Kansko-Achinsk coals».
The object of the study in this work is the boiler units of thermal power plants that burn slagging Kansk-Achinsk coals.
The subject of the study is the technological characteristics of the slagging process and the heat efficiency of the heating surfaces of steam boilers.

The aim of the work is to increase the thermal efficiency and operational reliability of the semi-radiation surfaces of steam boilers burning Kansk-Achinsk coals on the basis of experimental and calculated studies of the behavior of the mineral part of the fuel in the combustion process.

Objectives of the study:
1. The mathematical model of the slagging process of heating surfaces for steam boilers has been improve.
2. Eengineering method for calculating slagging of radiation surfaces of boiler heating, which allows determining the forecast of the process when the operating parameters of steam boilers change.

Practical significance of the work:1. Calculated data on the heat efficiency characteristics of the semi-radiation heating surfaces of P-67 boilers of Berezovskaya GRES-12. Technical solutions have been developed to improve the design, layout and system of technical diagnostics of heated heating surfaces for existing and projected boiler units when burning slagging Kansk-Achinsk coals
