Conditioning chamber

Bulk storage hoppers should terminate at a bin gate so that the feeding equipment may be isolated for servieing. The bin gate should be followed by a flexible eonneetion, and a transition hopper chute or hopper which acts as a conditioning chamber over the feeder. 

When air is humidified with water flow m and when the incoming and outgoing humid airflows are denoted m and m2, the energy balance of the conditioning chamber can be written as...

Fig. 43 Twin-trough chambers (A) and conditioning chamber (B) (Camag).

It is possible to control the relative humidity with sulfuric acid solutions of particular concentrations (Tab. 26) or with saturated salt solutions in contact with excess salt (Tab. 27). These liquids are placed in a conditioning chamber... 

Ascending, one-dimensional development in a trough chamber. After sample application the HPTLC plates were equilibrated in a conditioning chamber at 42% relative humidity for 30 min and then developed immediately. 

Since temperature and humidity affect results, it is necessary to condition each type of material as directed in the specification for that material. The test for dielectric strength must be run in the conditioning chamber or immediately after removing the specimen from the chamber. 

HPTLC plates Silica gel 60 F254 (Merck) that were prewashed before application of the sample, by developing once to the upper edge of the plate with chloroform - methanol (50+ 50), and then dried at 110 Cfor30 min. In the case of example A. the layer was conditioned to 0% rel. humidity in a conditioning chamber (over cone, sulfuric acid) after sample application.

The biodegradation of 1,3-DNB in water requires the presence of microorganisms that are acclimated to 1,3-DNB (ERA 1991b). Therefore, biodegradation of 1,3-DNB is not likely to occur in pristine waters. A mixed bacterial culture, with Pseudomonas predominating, adapted to metabolize phenol as the sole source of carbon had the ability to degrade 100 mg/L 1,3-DNB and 1,3,5-TNB under aerobic conditions (Chambers et al. 1963). Both compounds were slowly oxidized, and... 

A particulate-settling chamber is installed in a small heating plant that uses a traveling grate stoker. Determine the overall collection efficiency of the chamber, given the following operating conditions, chamber dimensions, and particle-size distribution ... 

The separation is carried out on Mikropolyamid F 1700 (Schleicher Schiill) with the solvent mixture toluene-glacial acetic acid (9 1). The uranyl lakes of the individual hydroxyanthraquinone dyes, which vary widely in their shades, are obtained on the chromatogram under standard conditions (chamber saturation) by subsequent dipping in a dilute solution of uranyl acetate (15). Table I shows the hRf values of the principal hydroxyanthraquinones contained in the various madder types. 

Natural Dyes Belonging to the Class of Hydroxyflavones. Figure 5 shows that the principal yellow natural dyes belonging to the class of the hydroxyflavones can be distinguished by TLC on Mikropolyamid F 1700 with the solvent chloroform-methanol-butanone-formic acid (6 2 1 1). Chromatography was performed under standard conditions (chamber saturation) and the color reaction was obtained with uranyl acetate. 

Florin and Bartesch described fluid-bed drying of soybeans (23). Unlike steam-jacketed vessels that transfer heat from the vessels wall into the seeds as the seeds tumble through the vessel, a fluid-bed conditioner uses air to suspend and move the seed through the conditioning chamber. If the air is heated, it can transfer heat... 

Depending on the particular operation, offgases from the incinerator may range from 1100° to 2100°F. Typically, the gases are sent to a conditioning chamber to lower the temperature to 500° to 600°F before they enter a scrubber. While the incinerator is in operation, the gases may remain above the acid dewpoint and corrosion problems will be minimal. But because most incinerators are cyclic operations with frequent periods of idleness, gas condensation in the inlet and outlet scrubber ductwork during shutdowns can cause serious deterioration. 

Waste incineration systems may use electrostatic precipitators in conjunction with a scrubber. The precipitator may come before or after the scrubber. If it comes after the scrubber, usually no special lining is required for it. But if it precedes the scrubber, the gases from the conditioning chamber enter the precipitator hot and are saturated with vapor. This process inevitably produces some cooling and consequently acid condensates. The glass block lining provides a lightweight, acid-resistant barrier and eliminates the need for external insulation on the precipitator.
