The Application of DDS Calorimeters in Different Industries

DDS Calorimeters are used in a wide range of applications : animal feed research, coal analysis, explosives analysis, fuel analysis, food & nutrition, oil analysis, universities, waste product analysis, cement manufacturing, just to name a few. There are various other applications continuously being added. Keep an eye on this page to read more about current and future applications.


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 food stock?

COAL 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, in short the 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 - Applications | DDS Calorimeters

FUEL ANALYSIS

As a general rule, volatile fuels are measured very seldom because they are very consistent. However, if a 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 of 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.

CEMENT MANUFACTURING

Isothermal calorimeters have been known to test the reaction of cement on hydration. Determining the heat of hydration of cement is important and traditionally, the heat of hydration has been determined by measuring the heat of solution. Typically, samples are mixed with water, where the cement hydration process can continuously be monitored over time.

FOREST WASTE

Solid biomass fuels are useful and a cost effective renewable energy source. The energy content of the biomass is determined by its calorific value. The calorific value of different forest species and bio-based industry residues can be used by companies specializing in processing raw biomass solid bio fuel production, small-scale consumers.

FISH OIL

Analyzing Fish Oil as an Alternative Fuel. Natural oils like olive oil, lard oil and fish oil can be analyzed using the DDS Oxygen Bomb Calorimeter range. The heat of combustion of the organic substance can be calculated with a small sample inserted into one of our DDS Calorimeters.

PULP & PAPER MILLS

Pulp and paper mills generate various quantities of energy-rich biomass as wastes, depending on the technological level, pulp and paper grades and wood quality. These wastes are produced in all stages of the process : wood preparation, pulp and paper manufacturing, chemical recovery, recycled paper processing, waste water treatment.

MARINE BIOLOGY - SEAWEED

The potential of seaweeds as biomass for energy production can be analyzed based in its calorific value, which is measured using an oxygen bomb calorimeter system (See the DDS Calorimeters range of oxygen bomb calorimeters). On analyzing seaweed it is found that it has a comparable calorific value with that of the conventional biomass fuels like bagasse, rice husks and corn cobs.

OLIVE MILLS

The processing and production of the olive fruit produces a large amount of by-products, including liquid and solid wastes arising from olive oil extraction and the production of table olives. The disposal of olive waste without any treatment is known to cause environmental problems.

COMPOST - ENERGY UTILIZATION

If produced compost does not meet the legal requirements for application to agricultural land, it is not suitable for application in soil, and can therefore be tested as an alternative fuel when co-fired with fossil fuels. Low-quality compost that cannot be applied to soils or for which there is no demand can be energy utilized for co-incineration with fuels of high calorific value.

FUELS IN BRICK-MAKING

Calorimetry is becoming increasingly necessary for kiln operations in various industries to test for quality and emissions. Some brick manufacturers are starting to utilize readily available alternative solid fuels like coal and sawdust, instead of using natural gas. These alternative fuels are available at a lower cost than that of natural gas.

STEEL MANUFACTURING

The large CO2 emissions from the steel industry and the concern for global warming are opening options to reduce fossil derived CO2 emission sin a steel plant by using biomass, but still keeping the production costs of steel reasonable. The worldwide steel industry is responsible for around one fifth of all industrial CO2 emissions.

Disposal of Hazardous Waste | DDS Calorimeters

HAZARDOUS WASTE DISPOSAL

The environmental impact of incineration of high to medium calorific waste in a specialized waste incinerator (usually as rotary kiln) can be tested with the aid of an oxygen bomb calorimeter. The type of wastes that can be incinerated in a rotary kiln include : Waste Oil, Waste Solvents, Refuse derived fuel : high calorific waste derived from municipal solid waste...
