Saving Energy with DDS Calorimeters

Our energy saving calculation will show you how much energy our calorimeters actually use.

Using our calorimeter we can establish the average heating value of coal to be 24MJ/Kg.

Presuming a coal power station runs on 40% efficiency it will require 375Kg to power a 100Watt light bulb for 1 year. So how much coal is that per day?

Well that is 375Kg divided by 365 days in a year, which works out to over about 1Kg of coal per day. But what is the value in 8 hours? So 1kg of coal per day divided by 24, divided by 8 and you get 0.342kg in an 8 hour day of coal used in a coal fired power station.

Some of our older calorimeters typically use 1300W. Let's do that calculation again...

0.342kg per 8 hours divided by the 100W load multiplied by the 1300W gives you 4.44kg per 8 hours of coal used to burn a 1300W load. That is 342kg per 8 hours.

So what does our 14W calorimeter actually use? Well, if 0.342kg per 8 hours, divided by the 100W load, multiplied by the 14W load, then the answer is 0.0479kg per 8 hours or 47g for 8 hours of coal used to burn a 14W load.

With every calorimeter comes an air cooler, which is typically 1200W, so let's do the same calculation again. 0.342kg over 8 hours, divided by 100W, multiplied by 1200W of load, will give you a usage of 4.1kg of coal per 8 hours.

By joining the two loads together you have an actual electrical load of 2500W. Now add the usages together of 4.1kg/8 hours plus 4.44kg/8 hours you have a total of 8.54kg over an eight hour period in the old calorimeters, comparing to our 47.9g over the same period.

Now that is saving energy, and saving our environment, and saving fossil fuels!
