WHAT IS A BOMB CALORIMETER?


DDS Calorimeters is the new home to the CAL2K and CAL3K Scientific Analytical Oxygen Bomb Calorimeter Systems. DDS and CAL3K offers the new next generation advanced bomb calorimeter system with innovative technology and never before seen advanced features.

The DDS CAL3K range is used to determine the calorific values of liquid and solid samples. The range of CAL3K oxygen bomb calorimeters is manufactured with various applications in mind; coal analysis and oil analysis being the most popular applications. The latest addition to the DDS Scientific range is the CAL3K-U bomb calorimeter, which is optimized for university use and educational institutions. The CAL3K-AP Oxygen Bomb Calorimeter combined the isothermal and adiabatic methods in one system.


WHAT IS BOMB CALORIMETRY?

Combustion Calorimeters measure the heat released from a combustible solid-liquid substance. This is done by weighing a precise measure of the sample substance into a crucible, placing the crucible inside a "bomb" (a sealed metal cylinder called a vessel), filling the vessel with oxygen and igniting the substance.

WATERLESS CALORIMETRY

We, at DDS, have replaced the water with an aluminium sleeve pressed over the stainless steel cylinder and we have placed the temperature sensors in a cavity between the steel cylinder and the sleeve. No water! No stirrer!

ABOUT DDS CALORIMETERS

Digital Data Systems are the proud designers and manufacturers of CAL2K Isothermal Oxygen Bomb Calorimeter Systems, CAL3K Isothermal, Adiabatic and Dynamic Bomb Calorimeters

The DDS CAL3K range is used to determine the calorific values of liquid and solid samples. The range of CAL3K oxygen bomb calorimeters is manufactured with various applications in mind; coal analysis and oil analysis being the most popular applications. The latest addition to the DDS Scientific range is the CAL3K-U bomb calorimeter, which is optimized for university use and educational institutions. The CAL3K-AP Oxygen Bomb Calorimeter combined the isothermal and adiabatic methods in one system. We call this new method dynamic. DDS has been designing and manufacturing high precision oxygen bomb calorimeters for over 30 years. The DDS Calorimeters are easy to set up, with easy removable connections, making the system compact, lightweight and easy to move.

CALORIMETER SYSTEMS

The calorific value of any solid or liquid material that can be safely burned in any of our CAL3K oxygen bomb calorimeters. All our bomb calorimeters are supplied with one or more bomb vessel(s) and the required installation kits (firing cotton, firing wire, benzoic acid tablets, consumables, etc.) The complete CAL3K system also includes the air cooler to cool the vessel after a determination. The CAL3K range of oxygen bomb calorimeters comprises of : a CAL3K calorimeter ( CAL3K-AP , CAL3K-A , or CAL3K-U, or CAL3K-F ), filling station (excludes CAL3K-AP ), a waterless external air cooler , Windows based software , printer and balance connection, balance connection. Our DDS oxygen bomb calorimeters offer high performance and low maintenance costs at a competitive and affordable price.

APPLICATIONS

The CAL3K can be applied in the coal, petrochemical, medical research, cement, power generation and animal feed research industries (to mention a few). The CAL3K can also be used to analyze coal, coke, oil, foodstuff and biomass products and is applied in power plants, coal mines, metallurgy, the chemical industry, for commercial inspection and scientific research. The use of multiple bomb vessels minimizes the waiting period by preparing the second bomb with a sample while the current sample is being analysed. Depending on your application, we recommend 2 bomb vessels per system, if needed. View all applications.

SYSTEM COMPONENTS

Convenient Waterless System - Our oxygen calorimeter is operated without water. No measuring, spilling or leaking. No water to heat or cool! The calorimeter is ready to use straight out of the box without needing to fill it with water, reducing sample preparation time. Our waterless principle increases determination speed, reducing electricity consumption (NO heating and cooling of water) and saving water. Old type calorimeters use a continuous supply of water, 1 to 3 litres per minute, which has a substantial environmental impact for the future. Upgrade to the latest in calorimeter technology in the all new CAL3K calorimeter range and save 126 000 litres of water.

External Cooling System - The all new CAL3K calorimeter system has an ingenious external air cooling principle. The primary design of the CAL3K bomb allows for fast air cooling, which is in some instances faster than the old CAL2K water cooler. All this cooling technology is achieved with only 12W electrical power and no water. The CAL3K external air cooler displays the time remaining until the bomb is ready to be used again and automatically switches off when the target temperature is reached.

Our bomb calorimeters are designed and manufactured to the highest international standards to endure and sustain large pressures inside the bomb chamber when the sample is ignited. The sample is ignited with a constant electrical energy during the firing process, whereafter the vessel is heated from the combustion process. The internal pressure within the bomb peaks (+/- 60bar) as the sample is burned and slowly subsides in the final stages of the determination.

A bomb calorimeter basically consists of a cup (crucible) to hold the sample, oxygen, a stainless steel vessel, the insulating container (to prevent heat flow from the calorimeter to the surroundings), an ignition system connected to the bomb for igniting the sample, filling station (either internal or external) for filling the bomb safely with high oxygen pressure and an external cooler for cooling the vessel down, ready for the next sample.

Both the CAL2K and CAL3K range feature a micro-processor based bomb vessel with automatic measurements of the calorific value of the sample, a clear LCD display, printer connection, connection to a standard keyboard, memory storage for data, real time clock, PC software for recording data, and full LIMS integration. The CAL3K offers a user interaction prompts on screen to assist in operation of the calorimeter. The working methods used in DDS calorimeters are : Isothermal (CAL2K, ECO, E2K), Adiabatic, Isothermal and Dynamic (CAL3K).
