Even the hardest residues can be removed from sensitive surfaces, as shown by the example of cleaning a graphite heat exchanger
. The inner tube surfaces of the shell-and-tube heat exchanger
were exposed to extremely hard, multilayer residues over the entire length of 3000mm.
When a global cement company was experiencing a high-pressure drop across the clinker cooler baghouse as well as ineffective cooling in the clinker cooler heat exchanger
at one of its North American plants, it reached out to Scheuch for help.
The order, valued at approximately SEK85m, is booked in the Welded Heat Exchanger
unit of the Energy Division, with deliveries scheduled for 2019.
Supression of latent capacity at higher face velocities: Under dehumidifying conditions, the coil handles both latent and sensible loads and its important to analyze the relative contribution of these two loads to the total capacity of the heat exchanger
. Figure 5 presents the distribution of two loads and the associated total capacity.
In order to further reduce the consumption values of such a system and thus to increase both energy efficiency and resource conservation, the smelting furnace manufacturer, ZPF GmbFI, has now extended its concept with additional components: By incorporating a so-called burner air preheating, in which the warm exhaust gas volume flow is passed through a pipe system to a heat exchanger
, the system operator has more room for maneuver--with lower pollutant emissions and lower gas consumption.
The future of the global heat exchanger
market looks promising with opportunities in the chemical, petrochemical and oil and gas applications
Two cross-flow air-to-air exchangers
, a heat exchanger
, and an energy exchanger
tested in this paper were manufactured with identical geometries (Figure 1 and Table 1).
A common failure that aging HVAC systems suffer in fall and winter months is the breakdown of the heat exchanger
because of thermal fatigue.
Many application demands can be met from a modularised standard range of heat pipe heat exchangers
, where 'cartridges' of heat pipes are installed into a standard heat exchanger
casing that's suitable for its application.
One HVAC component particularly susceptible to thermal fatigue is the system's heat exchanger
. These are found in every gas- or oil-fired split system or packaged unit application, and they provide an efficient method of transferring the heat created by the burners to the supply air, while segregating the combustion gasses from the air itself.
Liu et al  compared the overall performance of shell and tube heat exchanger
using rod baffles and rod-vane baffles and they found that the rod-vane baffles gives better overall performance of heat exchanger
3D Systems' direct metal printing process allowed researchers to use unconventional, variable shapes that increase the heat exchanger
