During major overhaul of the lining of a DKVR-10/13 boiler PP Spetsinzhstroi together with ChP NPF
Alineka carried out work for restoring the brickwork and lining of a boiler with new refractories of ChP NPF
Alineka. The results of one year’s boiler operation demonstrate the reliability and efficiency of a lining made
of the new materials.
The steady increase in the price of energy resources in
the world induces Ukrainian enterprises, that tend towards
their own production and remain in Ukrainian markets, to
move into external markets and be concerned with opti-
mizing energy consumption.
One of the common factors that negatively affect the
energy content of Ukrainian enterprise production is use of
ageing equipment with low energy efficiency. This parti-
cularly concerns thermal power engineering equipment,
especially boilers. As a rule in boiler installations there is
operation of boiler grades DKVR, DE, GM, having a service
life of twenty years or more. Often imported boilers are
operated that serve for more than fifty years (Bruon,
Babcock Wilcox, Steinmuller, etc.). It is quite complicated to
replace boiler equipment by more economic and modern
units for the majority of enterprises due to a lack of licensing
procedures and the high percentage for credit, and therefore
one way of increasing their energy efficiency is boiler
From a heat engineering point of view the construction
of the majority of boilers operating in industrial enterprises
makes it possible to obtain a high efficiency in steam
production, although actually it is not always possible to
achieve this. One of the common reasons making it im
possible during operation to maintain a high efficiency if use
of ageing and physically worn automation systems used in
boilers. Another reason, causing a reduction in the rated
mean operating efficiency is use of old materials for lining
that do not withstand constant changes in thermal loads, to
the extent of partial stoppages and star-ups, which is
currently quite typical for contemporary operating conditions
for many enterprises, particularly in the food industry.
The negative effect of both factors on efficiency is
typical, in particular for boilers of the DKVR (DKV) type.
For example, it is necessary to repair or change burner blocks
every one or two years. In the opposite case there is reduc-
tion in boiler efficiency and individual parts of the lining
within the furnace break down (Fig. 1). The lining of the
boiler walls due to instability of thermal loads is covered in
cracks (Fig. 2), through which there is a sharp increase in
inflow of air that also reduces boiler efficiency.
It is possible to overcome the effect of both factors by
changing the boiler automation system by a modern system
based on microprocessors and to make walls with contem
porary materials. In addition, it is necessary to partly change
the lining construction during repair. Realization of these
