In both the impedance-frequency (|Z|-f) characteristics of the cation and the anion exchangers
, the increase of |Z| was observed in the frequency range lower than [10.sup.2] Hz.
company is looking to expand its sales of exhaust gas heat exchangers
based on the popularity of cogeneration, it continuos to produce a variety of heat exchangers
for other cooling applications.
ViscoLine tubular heat exchangers
incorporate corrugated tubes or other advanced profiles designed to increase the turbulence in the flow of the liquid.
Those who sin, too, are the ones who give the exchangers
some money in cash and then if they take it in treasury notes for themselves or for others and not in cash when the accounts are done with, they make [the exchangers] offer the payment for having given to them in cash, which is at least at 2 percent.
But prototypes for cars and even motorcycle heat exchangers
have been produced and aggressively promoted directly to OEMs.
Three heat exchangers
were fabricated and installed between the primary kiln and the second-stage chambers.
For many years mycon uses the self-developed TubeMaster process for cleaning tubes and tube bundle heat exchangers
. One of the focus is cleaning of sulphur condensers.
Under the terms of the agreement, the company's order comprises of compact heat exchangers
for energy recovery in a chemical process, where low octane refinery naphtha's are converted into high-octane liquid products.
Fin-and-tube heat exchangers
are widely used in many HVAC&R applications.
Increasing power generation capacities, and rise in technological advances in heat exchangers
are big contributors too, it pointed out.
Important factors in the energy recovery are weather condition, the performance of the exchangers
, and operation duration (Besant and Simonson 2000).
In HVAC heat exchangers
, thermal fatigue is accelerated by the corrosive combustion gasses that pass through the heat exchanger
tubes on their way to the exhaust flue and by condensation that may collect in the heat exchanger
during heat transfer.
Yet British industry is facing mounting problems with the design of its conventional heat exchangers
Shell-and-tube heat exchangers
(STHXs) are used in many industrial areas, such as power plant, chemical engineering, petroleum refining, food processing, etc.
The University of Maryland, through a partnership with 3D Systems and the DOE's Building Technologies Office, is using 3D printing to create heat exchangers
. This next-generation device weighs 20% less, performs 20% more efficiently and can be manufactured more quickly compared to current designs.
