CAL3K-AP Oxygen Bomb Calorimeter System

AN AUTOMATED SYSTEM WITH LESS OPERATOR INPUT – Our top of the range product is our faster calorimeter in the CAL3K range. The CAL3K-AP has a sample repeat speed of 4-6 minutes per sample and can handle more than 10 samples per hour for faster throughput. The CAL3K-AP is suited for a clean and well maintained laboratory with a requirement for very fast and accurate results.

APPLICATION : The CAL3K-AP is best suited for a clean and well maintained laboratory with a requirement for very fast an accurate results.

The CAL3K-AP Calorimeter uses a combination of the Isothermal and Adiabatic methods, while still using the dry method, i.e. it is waterless. The minimum determination time is up to 4.5 minutes. There is no need for an external oxygen filling station as the vessel is automatically filled with oxygen inside the bomb calorimeter and the pressure is monitored. It uses a combination of the Isothermal and Adiabatic calorimetry methods, while still being waterless. There is no need for the external oxygen filling station as the vessel is automatically filled within the calorimeter. The CAL3K-AP system comes complete with the calorimeter, bayonet bomb vessel and one air cooler.

CAL3K-AP OXYGEN BOMB CALORIMETER SYSTEM

The complete CAL3K-AP oxygen bomb calorimeter system contains all the parts and consumables necessary to set up the unit. The installation kits included with the setup of the calorimeter contains consumable for approximately 200 samples, depending on the type of sample being analyzed (coal analysis, animal feed analysis). Other samples like oil, might use more consumables as they are corrosive and could cause wear and tear. Additional consumables can be purchased separately (and in bulk quantities) for our authorized agents.

CAL3K-AP APPLICATION

It is best suited for a clean and well maintained laboratory with a requirement for very fast and accurate results.

CAL3K-AP PERFORMANCE

The CAL3K-AP uses a combination of the Isothermal and Adiabatic calorimetry methods, while still using the dry method, i.e. it is waterless. The minimum determination time is up to 4.5 minutes.

There is no need for an external oxygen filling station (CAL3K-AP) as the vessel is automatically filled with oxygen inside the bomb calorimeter and the pressure is monitored. The oxygen filling pressure can be changed (programmed) on the bomb calorimeter. The vessel pressure is monitored before firing for leaks and after firing for results quality assessment.

The fastest performance was achieved with one CAL3K-AP, 3 vessels and 2 coolers. This is a full occupation for a single operator.

COMPLETE CAL3K OXYGEN CALORIMETER SYSTEM

The CAL3K calorimeter requires a PC keyboard (as seen above/left with the complete system) to enter commands. The new lid design has two shocks which open the lid automatically. This is really a nifty new feature. The CAL3K-AP Oxygen Calorimeter will be supplied as a complete system which includes the calorimeter, the new air cooler , and 2 bayonet oxygen vessels.

The LCD display has 4 lines, the picture below only showing two of the lines. The first line shows what the CAL3K is doing at present, e.g. what mode the calorimeter is in and what it is doing.

LCD SCREEN

The second line shows the action the operator should take, e.g. "ENTER MASS, INSERT BOMB", etc. The third line is reserved for keyboard command and data entry, e.g. Enter Benzoic Acid Value in MJ. The fourth line gives additional information relating to faults and actions. If the subject help is activated then all 4 lines are used to display the help functions.

CALORIMETER WELL AND AUTOMATIC FILLING

This is the CAL3K Oxygen Bomb Calorimeter with the lid open. The new gas shocks allow for automatic opening. The shocks open the lid to 45°C, so that the well can ventilate after each sample determination.

The ATC HEATER (Ambient Temperature Control) insulates the oxygen bomb vessel from the outside environment. It contains heating elements designed so that the ATC temperature follows the vessel temperature.

BOMB WELL - The bomb well has a contact arrangement at the bottom to connect to the bomb electronics.The vessel temperature and calibration data are retrieved from this contact.

FILLING NOZZLE - The filling nozzle connects the bomb cavity to the high pressure oxygen and the deflating valve.

TOP CONTACT - Through this top contact the bomb is fired.

The electronics compartment is located in the blue side panel of the calorimeter. This electronics compartment is the "brain" of the calorimeter, as we like to call it. This is what makes everything work. There you will find the firing circuit and the ECU card, which can easily be removed, making maintenance quick and easy.

OPERATOR ASSISTANCE

The CAL3K Calorimeter has some added features which will make the operation of the oxygen calorimeter a lot easier and user friendly. Every step in the determination of the calorific value of the sample has a help screen attached and operator prompts assist with step-by-step instructions to operate the calorimeter.

EVENT LOGGING - The CAL3K-AP has 63 event classifications and can store a maximum of 6800 logged events.

DEFAULT PARAMETER FIELDS - The CAL3K-AP has 1 default parameter field for each mode. All fields are for different operation and operating modes.

FAULT AND FIELD TESTING CAPABILITY - The CAL3K-AP and vessel each have a factory and a field test built in. The field test allows the operator/user to test the functionality without any instruments or special connections.

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.

View Application
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.

View Application
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.

View Application
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.
