CAL2K COMPLETE SYSTEM
The complete CAL2K system consists of : The CAL2K-1 Calorimeter, CAL2K-1-KT Calorimeter Installation Kit, CAL2K-2 Water Cooler, CAL2K-2-KT Cooler Installation Kit, CAL2K-3 Filling Station, CAL2K-3-KT Filling Station Installation Kit, CAL2K-4 Vessel and the CAL2K-4-KT Vessel Installation Kit.
The CAL2K-1 Calorimeter can operate as either a stand-alone unit or via a PC.
When operating as a stand-alone unit it is operated via the keyboard and all relevant information is displayed on the LCD Display. Up to 7 Calorimeters can be connected as a network with or without a PC.
The CAL2K-4 Vessel is the first of its kind and is the heart of the CAL2K System.
Its sophisticated design allows the temperature to be measured to five decimal places in degrees Celsius. The vessel is an intelligent (SMART) vessel with a microprocessor built into its base. The vessel is capable of : firing counts, identification, memory and reconditioning data.
The vessel is the combustion chamber. It is made of stainless steel and tested up to a pressure of 300 atmospheres (4200psi).
The CAL2K Filling Station
The Filling Station is designed to fill the vessel with oxygen to 3Mpa.
The filling rate is controlled so as not to disrupt the sample in the crucible. The Filling Station is extremely easy to operate and requires minimal adjustments and maintenance.
The CAL2K Water Cooler
The unit is designed to reduce the temperature of a recently fired vessel, obtained from the calorimeter, to ambient temperature in 2-3 minutes.
Solid state cooling is used and the hot junction of the peltier elements is cooled by a continuous trickle of water from the mains water supply.
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.
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.
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.
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.
Simple, we at Digital Data Systems (DDS) have been making calorimeters for the last 40 years. We have a wealth of technical knowledge and calorimeter experience second to none. We are continuously improving our systems with the latest technology as it becomes available, allowing the students to work on a cost effective, easy to use...
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.
