CAL3K-AP Calorimeter

CAL3K-AP Oxygen Bomb Calorimeter System

AN AUTOMATED SYSTEM WITH MINIMUM OPERATOR INPUT – Our top of the range product is the most automated calorimeter with a repeat sample speed of 7 minutes. Faster speeds are available on request. The CAL3K-AP is used in factories and scientific laboratories alike and requires a minimum of space and installation. It uses no water and requires ~0.5 watt to operate.

APPLICATION : The CAL3K_AP is useful when a sample can be burned (ignited) and the released heat needs to be measured. It applies to food processing, feed stock composition, material and waste analysis, quality control, recycling and alternative energy harvesting.

OPTIONS : Multiple vessels, and multiple coolers to suit your application.

THE CAL3K-AP CALORIMETER

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 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. The minimum CAL3K-AP system comes complete with the calorimeter, two bayonet bomb vessel and one air cooler. It can be expanded to 4 vessels and 3 coolers should your application requires it.

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 original purchase 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

All samples which can be ignited and where the released heat needs to be measured. It applies to food processing, feed stock composition, material and waste analysis, quality control, recycling and alternative energy harvesting. Special requirements are welcome and we have a library of weird and wonderful applications, including solid rocket fuel and explosives.

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 - 6 minutes. This can be adjusted to your needs via the included computer interface.

There is no need for an external oxygen filling station (3K-3) 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 and achieves 12 samples per hour.

COMPLETE CAL3K OXYGEN CALORIMETER SYSTEM

The CAL3K calorimeter requires a PC keyboard (as seen above/left with the complete system) to enter commands. The lid design has two shocks which open the lid automatically after a determination. This is really a nifty feature. The CAL3K-AP Oxygen Calorimeter will be supplied as a complete system which includes the calorimeter, the air cooler , and 2 bayonet oxygen vessels. It can be expanded to 4 vessels and 2 coolers.

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 (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. The ATC is cooled after a determination.

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 via this contact.

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

TOP FILLING HEAD - The vessel is filled, deflated and the sample is ignited through this filling head.

The electronics compartment is located in the blue side panel of the calorimeter. This electronics compartment contains the control card and the firing circuit. This is what makes everything work. The control card contains all ports (Keyboard, printer, balance, USB, BlueTooth) and is exchangeable for easy maintenance.

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-A has one1 default parameter field for each mode and one experimental default mode for the user. All fields are for different operation and operating modes. The experimental mode can be changed via the PC interface. Note that the each operating mode requires a calibration.

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?

View Application
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.
