The type of waste heat boiler is developing from small to large, the design structure is constantly changing from simple to complex, the form is gradually becoming diversified, and the boiler efficiency is constantly improved. If the power used is different according to the water cycle, Waste heat boiler manufacturer express Waste heat boiler can be divided into natural circulation waste heat boiler and forced circulation waste heat boiler.

The thermal system of waste heat boiler power station adopts 1.57~3.43MPa~340~435 ℃ relatively high temperature and high pressure main steam parameters, providing guarantee for improving waste heat power generation;

The natural circulation waste heat boiler relies on the density difference between steam and water to form a water cycle. In order to make the water cycle stable and safe, the resistance of working medium in the pipe should be relatively small, so it needs a thicker pipe and a larger steam drum. This means that the metal consumption increases, the boiler has a large water air space and heat capacity, and the thermal inertia is relatively large, which prolongs the startup time of the boiler. When the load changes, it is easy to generate large thermal stress. Therefore, this type of waste heat boiler is suitable for working under stable load conditions.

Industrial and mining enterprises all have industrial waste heat, which belongs to secondary energy. Industrial waste heat refers to the local heat generated in the process of consumption that could have been used but could not be used to discharge to the surrounding environment in practice. Application of industrial waste heat is called waste heat application.

waste heat Boiler manufacturer The forced circulation waste heat boiler relies on the circulating pump to circulate the working medium of the system, but the pump consumes additional work, reducing the efficiency of the whole system. In practical application, the circulating pump can be used to establish a stable water circulation at the start-up stage of the boiler. When the system is stable, the circulating pump can be closed, and the steam water circulation can be carried out by relying on the natural circulation mode. This is the so-called composite waste heat boiler.

Once through waste heat boiler, that is, the feed water directly enters the heating surface under the action of the pump to form steam extraction, canceling the water cycle. This type of boiler is characterized by no steam drum, greatly reduced water air space and weakened thermal inertia, thus changing the boiler's response to load changes. However, it has high requirements for water quality, materials and operation.
