The corner tube boiler uses a piping system as the skeleton of the entire boiler, and it bears the full load of the boiler, which makes a non-framework boiler. At the same time, this skeleton also serves as the down tube of the boiler and upper and lower headers.
The boiler drum is an external type drum, the furnace is a fully enclosed membrane wall structure, the convective heating surface adopts the flag structure.
The corner boiler has the advantages of compact structure, low steel consumption and rapid temperature increase, which makes the boiler very popular. The boiler is field assembled boiler.
Feature
1. In the event of a power outage, the water system does not vaporize and the water circulation is safe and reliable.
2. The upper part of the boiler can be divided according to the size of the railway transportation limit.
3. The excess air coefficient after the heating surface of the boiler tail is only less than 1.2, which not only reduces the heat loss of the exhaust fumes, reduces the power consumption of the induced draft fan, but also greatly reduces the environmental pollution of the boiler house.
