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.
