The paper discusses the threat of decommissioning to the
thermal power plant (TPP) heat exchanger tubes because
of erosion and develops a computer‐integrated control
system (CICS) for the process of distribution of steam
coal flows with different indicators of abrasive materials
content, which is based on fuzzy logic.
The problem of rapid decommissioning of TPP heat
exchangers, particularly abrasive damage to furnace
screen tubes, economizer, superheater, etc. This may
indicate a discrepancy between the expected fuel ash
content and the actual one, as well as a high content of
abrasive impurities in steam coal.
The work aims to develop a CICS of the wear resis‐
tance of the heat exchange surface of a steam boiler of a
coal‐fired power plant by measuring and fuzzy control of
the content of abrasive impurities in steam coal.
The problems of damage to the equipment of the TPP
boiler are investigated, and a system for controlling the
wear resistance of the surface by automatic fuzzy control
of the quality of coal is developed. The results were
investigated during coal preparation and combustion in
the furnace of a thermal power plant to investigate the
effectiveness of the proposed fuzzy controller. The model
results confirm the feasibility of the fuzzy control method
for the system with different coal quality parameters
