Industrial Self Supporting Corner Tube Boiler With Natural
Circulation Cooling
Description
The corner tube boiler is a water tube boiler with natural
circulation cooling. This type of design has proven itself in the
most difficult of operating conditions. The first corner tube
boilers were designed for low power capacities (for lorry engines).
Nowadays, corner tube boilers are manufactured for ever higher
power capacities and pressures. The advantage of the corner tube
design is that not only can it be used for steam generation but
also for the generation of hot water, heating thermal oil, and
heating or cooling other heat exchangers.
Installation
The self-supporting corner tube boiler is erected in such a way
that it can be expanded as desired in all directions from its
bearing surface. The compact tube system can be completely finished
in the workshop under favourable conditions and with continuous
quality control. Larger boilers can be divided into separate
components and reduced to a transportable size in the workshop.
Only a few pressure parts, such as the header and the distributor,
are disassembled; these can be reassembled relatively easily at the
final location.
