Classification
We can manufacture three types of boiler economizers: bare-tube economizers, H-finned tube economizers, and spiral finned tube economizers. The H-finned tube economizer is a high-efficiency heat exchanger economizer composed of H-finned tubes.
Compared with bare-tube economizers, H-finned tube economizers can expand the heat exchange area and reduce the number of tubes. They can also increase the flue gas flow area to reduce the flue gas flow velocity and abrasion.
H-finned tubes can be made into double H-finned tubes, which have high rigidity and are suitable for long tube rows. The spiral finned tube economizer is a newly designed heat transfer equipment composed of spiral finned tubes, developed to overcome the problems of severe abrasion and short service life.
Precautions for Use
1. Always ensure that the superheater operates within the specified temperature and pressure range.
2.Regular maintenance and inspection are crucial to keep the superheater in optimal condition.
3.Ensure that the superheater is installed by qualified professionals to guarantee correct setup and operation.

Around the boiler combustion chamber |
Usually laid vertically on the inner surface of the furnace wall, it is mainly used to absorb the radiant heat from the flame and high-temperature flue gas in the furnace.It is the main type of evaporative heating surface of modern boiler and also the basic part of water circulation loop of boiler.As a combination of cooling and protective furnace wall.
The water-cooling walls were originally designed not to be heated, but to cool the furnace so that it would not be damaged at high temperatures.Later, as a result of its good heat exchange function, gradually replaced the drum to become the main heating parts of the boiler.
An evaporative heating surface composed of many parallel pipes is arranged on the inner wall of the boiler furnace.The role of the water wall is to absorb the radiant heat of the high temperature flame or flue gas in the furnace, generate steam or hot water in the pipe, reduce the temperature of the furnace wall, and protect the furnace wall.In the large capacity boiler, the flame temperature is very high and the intensity of thermal radiation is very high.The boiler contains 40 to 50 percent or more of the heat absorbed by the water wall.With the exception of a few small capacity boilers, modern water tube boilers use water cooling walls as the main evaporative heating surface.
