Description:

H Finned Economiser in Steam Boiler

Finned Tube----Square fin tube, H fin tube, rectangular fin tubes, double H fin tubes

H fin tube known as square fin tube, There are two type of H fin tubes, one type with single tube, normal called square fin tube, the other with Double tube, normal called rectangular fin tubes. and also manufactured as per customers requirements. Due to rectangular shapes, which can offer large surface area compared to the Spiral Finned tubes. Due to larger surface area available, these finned tubes are used mostly in Air Heating application to reduce the overall size of the equipment.

H fin tube is a kind of boiler parts, to have two steel circular symmetry to be welded on fluorescent tubes to form fins positive shap 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.

Principle:
H-economizer two rectangular fin, similar to a square, its edge length for the fluorescent tubes of 2-fold, an expansion of the heating surface.
H-economizer flash resistance welding processes used, the welding seam after the high rate of fusion, weld tensile strength, and has good thermal conductivity. H-economizer can also manufacture dual tube "double H" type fin tubes, its rigid structure, and can be applied to a longer tube row occasion.

Max. Working Temperature: 300 °C
Atmospheric Corrorsion Resisitance: OK
Mechanical Resistance: Good
Fin Material: Copper, Aluminum, carbon steel, stainless steel
Base Tube materials: Any material available, such as Carbon steel Tube, A179, A192, A210, stainless tube A269/A213 T5 T11 T22 304 316

Rectangular Finned Tubes

Single pipe square finned tubes and twin pipe rectangular finned tubes are also manufactured as per customers’ requirements. These are particularly suitable for dust laden exhaust gases, e.g. for economizers in coal and oil fired units or waste incinerators.


Technical specifications



Material Structure
Consists of a serious of H-finned tubes, the headers of inlet and outlet, bend, frame and other auxiliaries.
Structure Arrangement
In line / staggered arrangement.


H Type Tube Heat Exchanger Exhaust Gas Economizer With Headers

Functions


1. Absorb the heat of low-temperature flue gas, reduce the smoke exhaust temperature, reduce smoke loss and save fuel.

2. Since the feed water is heated in the economizer before entering the drum, the heat absorption of the feed water on the heating surface is reduced, and the economizer can be used to replace part of the high-cost evaporative heating surface.

3. When the feed water temperature is raised, the wall temperature difference will be reduced and the thermal stress will be correspondingly reduced to extend the service life of the steam drum.

*Note:HD BOILER can bespoke special type of economizer according to customer's requirement.


Internal heat exchangers


1.Subcooling may also be produced by superheating the gas leaving the evaporator and heading to the gas compressor.
2.These systems withdraw heat from the liquid line but heat up the gas compressors suction.
3.This is a very common solution to insure that gas reaches the compressor and liquid reaches the valve.
4.It also allows maximum heat exchanger use as minimizes the portion of the heat exchangers used to change the temperature of the fluid,and maximizeds the volume in which the refrigerant changes its phase.
