High Frequency Welding Customized Coal Fired Steam Boiler Parts Stack Economizer Coil

Boiler economizer

Boiler Economizer is the energy improving device that helps to
reduce the cost of operation by saving the fuel. The economizer in
Boiler tends to make the system more energy efficient. In boilers,
economizers are generally designed to exchange heat with the fluid,
generally water. The exhaust from the boilers is generally in the
temperature range of 200°C – 250°C, so there are a huge amount of
losses from the boiler if any heat recovery devices are not
installed after it. Boiler Economizer that suit your boiler system
and will increase its overall efficiency from 3% – 5%. Increase in
boiler efficiency will save a lot of your operating cost and
eventually will prolong the life of your boiler system.

We can manufacture three types of boiler economizer, bare tube
economizer, H-finned tube economizer and spiral finned tube
economizer.

Product Description

1.Finned Tube Heat Exchangers consist of a shell and finned tubes assembly.

2.Fins are used to increase the effective surface area of heat exchanger tubing.

3.Finned tubes are used when the heat transfer coefficient on the outside of the tubes is appreciably lower than that on the inside;as in heat transfer from a liquid to a gas,vapor to a gas ,such as steam to air heat exchanger, thermic fluid to air heat exchanger, when an extended surface is needed on only one fluid side or when the operating pressure needs to be contained on one fluid side.

Technical parameter

Medium	air, flue gas, thermal oil, water, brine, refrigerant, etc.
Temperature	standard heat exchanger to 560 ° C by special materials can be higher
Pipe materials	carbon steel, stainless steel, alloy or special materials
Ribs materials	carbon steel, stainless steel, non-ferrous metal, alloy or special materials
Thermal insulation &Surface treatment	according to customers specification

Features

1. The equipment body can be designed into many modules to ensure the long term and stable running;

2. Compact structure which can enlarge the heat exchanging area in order to add the heat transfer area and less leakage

3. Improve the heat transfer efficiency

4. Structure arrangement: In line or staggered arrangement

Details

1.Our products can be modified according to our customers' needs and the situation.

2.we design and manufacture safe,reliable and efficient H-fin tubes.HD BOILER has also completed stand-alone product quality assurance systems.

3.Production of H-fin tubes are with high heat transfer efficiency, they have flue gas resistance and are designed for a small space.
