CAL2K Bomb Vessel
The DDS Bomb Vessel is unique in that it is the first of its kind and is packed with features.
The improved CAL2K vessel is designed to fit perfectly into each calorimeter in the CAL2K range. Various improvements are made to ensure accurate results with each determination. One of the bomb vessel's innovative design elements includes temperature sensors built into the wall of the vessel.
VESSEL FEATURES
The First of Its Kind.
A bomb vessel as unique as its features.
The CAL2K bomb vessel is the first of its kind in calorimetry. The microprocessor in the base of the vessel provides accurate results with each analysis. The complete lid assembly holds the crucible containing the sample for determination. Temperature sensors are built into the wall of the vessel for effective temperature measurement. The vessel is filled with up to 3000 Kpa of oxygen for each determination. Measuring calorific values has never been this easy.
Small. With thermal balance.
The bomb vessel is smaller than conventional vessels, which results in a smaller heat capacity. Special attention has been given to a thermally balanced vessel design. Computer aided design (CAD) and computer simulation of heat transfer characteristics is used to achieve this.
8 Temperature Sensors.
The vessel has an oxygen volume of 0.22 liters (220ml), which allows for a 0.5g coal sample at approximately 30MJ/Kg. The temperature sensors are located cylindrical within the vessel walls at eight places for accurate temperature measurement.
Accurate results with Benzoic Acid.
The approximate temperature rise of the vessel after burning of 0.5g Benzoic Acid is 9 degrees Celsius. Practical tests have shown that up to 0.8g of Benzoic Acid can be burnt without affecting the accuracy. Oxygen starvation affects the results with higher charges. Certified Benzoic Acid Tablets.
Intelligent "SMART" Vessel.
The heart of the vessel is the intelligent microprocessor built into the base of the unit. All the information pertinent to a vessel is stored permanently inside the vessel. This includes information regarding the : vessel number, calibration, number of firings, date of last reconditioning, etc.
Compatible with all CAL2K Calorimeters.
The vessel PCB is only powered up when placed in the calorimeter. The result of the vessel memory is that any vessel can run in any calorimeter without a new calibration.
Sealed for extra protection.
The vessel memory can only be accessed from the PC. The electronics and sensors are vacuum epoxy impregnated to prevent physical damage as well as moisture from entering the electronics.
Semi-permanent firing wire.
The firing wire is semi-permanent and only needs to be replaced when the wire is burnt or damaged.

Animal Feed Research
Food calories are measured in KJ/g, the same as combustible calories. However, the process is different, although the outcome is the same : KJ/g or heat, or calories. Animal feed stock relies on the animal digestion (conversion). A calorimeter burns the lot and measures the released heat. Then a calorimeter can't be used to measure feed stock?

Coal & Coke Analysis
The coal industry is the traditional application of calorimeters because coal has a variety of properties, apart from being black. If the coal is used for steam generation then the calorific value is of paramount importance. The calorific value, short CV, is a measure of how much heat can be extracted from it.

Explosives Analysis
Only explosives which can be ignited by heat from the calorimeter's firing circuit can be tested in the oxygen calorimeter. Then very minute/small quantities are used for analysis. The calorific value of an explosive is not very high, but the burning speed is.

Fuel Analysis
As a general rule, volatile fuels are measured very seldom because they are very consistent. However, if the fuel absorbs water, then frequent analysis is called for. Volatile fuel such as alcohol must be prevented from evaporating during the handling process that is from weighing to ignition of the sample.

Food & Nutrition Analysis
Here is an example of food calories from www.scientificamerican.com. As the article says: "The method of using a combustion calorimeter to measure food calories is not frequently used today. However, after some considerations it can, and is, used today for checking the production quality of food." Let's look at the details.

Oil Analysis
Oils are a non-volatile substance. In general they are not measured frequently because they are very consistent and uniform. Other oil properties are more important than the calorific value, such as taste or viscosity. If an oil is measured in an oxygen calorimeter, then the procedure would be the same as a solid substance.

Waste Product Analysis
Heating energy is being dumped on our municipal landfill sites. Our landfill sites are being clogged by plastic waste, which battle to bio-degrade over time. Alternative options for managing plastic waste has been identified as mechanical recycling, cement kilns, power station and energy recovery by incineration. Having plastic on landfill sties should be the last option.
