Industrial boiler component H finned tube economizer for gas boiler is a kind of boiler parts, to have two steel circular symmetry to be welded on fluorescent tubes to form fins positive shape much like letter "H", so called H-fin tube. H-economizer widely used in utility boilers, industrial boilers, marine power, such as the tail of heat exchanger components.
Application of H Finned Tube Economizer
H finned tube economizers for gas boiler are tube heat exchangers located in the top section of a boiler. They raise the feedwater temperature to slightly below saturation temperature. Economizers are so named because they can make use of the enthalpy in fluid streams that are hot, but not hot enough to be used in a boiler, thereby recovering more useful enthalpy and improving the boiler's efficiency. Economizers preheat the cold water used to fill water wall panels.
Characteristics of H Finned Tube Economizer
1). Add the heat exchange area and reduce the number of tubes, also increase the fume flow section area to reduce the fume speed and abrasion.
2). H type fin tube can be made to double H type fin tube, high rigidness to fit long tube row.
3). H type fin economizer arranged in line to make the space into many small zones, averaged air flow to reduce the abrasion.
4). With straight channel to gain the best ash-blowing effect.
5). The compact structure to reduce the weight and reduce the manufacturing cost.
