1. What is Bomb Calorimeter
A Bomb Calorimeter is an apparatus used for measuring heats of combustion. HAMCO6A to 6E Digital Bomb Calorimeter provides a simple, inexpensive yet accurate method for the determination of heat of combustion and the sulfur contents of liquid and solid hydrocarbons and other fuels. HAMCO 6A to 6E Bomb Calorimeter is widely used in Industries in diversified fields for quality control, testing laboratories for research & development, and in teaching establishments.

2. What is Bomb Calorimeter Used For
Hamco Make Bomb calorimeter ( All Model From Hamco6A to 6E) is used For Measuring Gross Calorific Value of Any Solid and Fuels. It can not be Used for Gaseous Fuel. It is a constant Volume type of Calorimeter, which measures the Heat of a Particular reaction and thus measures the Calorific value of Fuels.

3. Bomb Calorimeter Principle
A sample is weighed and placed in a heavy-duty stainless steel cylinder referred to as a Bomb. The Bomb is then sealed with oxygen and the sample is ignited electrically. The complete oxidation of the compound releases heat and this is measured through the temperature change of the water bath surrounding the bomb. A digital sensor measures the rise in temperature. The heat of combustion at constant volume can be calculated from the resulting rise in temperature.

4. Types Of Bomb Calorimeter :-
There are three Types of Bomb Calorimeter which is Adiabatic, Isoperibol and Isothermal.

  • Adiabatic Bomb Calorimeter :- In which the transfer of heat between system and surrounding is Prevented.
  • Isoperibol Bomb Calorimeter :- In which the transfer of heat between system and surrounding in small controlled heat exchange is allowed.
  • Isothermal Bomb Calorimeter :- In which either work or heat may be used to maintain constant temperature within system.

5. Standards if Follows :-
Confirm to the specification ASTM D 4809, D 240, DE711, IS -1350- 1966, BS 1016 PART 5-1967, IP 12/63 T.

6. Summary of Test Method :-
The heat of combustion is determined by burning a weighed sample in an oxygen-bomb calorimeter under controlled conditions. The temperature increase is measured by a temperature reading instrument which allows the precision of the method to be met. The heat of combustion is calculated from temperature observations before, during, and after combustion, with proper allowance for thermochemical and heat transfer corrections.

7. What are Buyers Scope :-
The Buyer Need to arrange Oxygen cylinder with Key, Balance with 0.1 mg Least count or Max 1 mg, Distilled water approx. 20 Ltr.

8. Type of Sample it can Measure :-
It can measure any solid, any liquid. No gaseous material can be measured. High energy Fuel (Which is having GCV above 20000 Cal/gm) can be measured with reduced volume.

9. Different Models of Bomb Calorimeter :-
HAMCO Make Manual, Semiautomatic, and Fully Automatic Bomb Calorimeter. Bomb Calorimeter all operations have been divided into Major 5 segments. 1) Sample preparation, 2) Oxygen Filling 3) Temperature Rise detection 4) Calculation 5) Reporting & Corrections.

  • Manual Bomb Calorimeter :- In Manual Bomb calorimeter all this 5 thing Need to do manually. We suggest this model only to colleges and institute where accuracy and operator skill is not important. This model is only for demo purposes. We don’t suggest this model to Industries.
  • Semiautomatic Bomb Calorimeter :- In semiautomatic Bomb Calorimeter All other thing except temp rise detection has been done by Microprocessor. This usually takes around 10-15 minutes and this is where operator skill requires is the most. Hamco has done it automatically to reduce the error. While Operator is free for 15 minutes, his time is also saved to do other tasks. While in the manual model the operator skill required is the most, while is this model Operator skill requires is Optimum. He just needs to take the data from the microprocessor and do the calculation. This model we suggest to industries who want to do GCV Calculations but his budget doesn’t allow him to go with an automatic one.
  • Automatic Bomb Calorimeter :- In Automatic Bomb Calorimeter Except Sample preparation , everything has been done automatic. Our HAMCO Make Bomb Calorimeter is a single unit that doesn’t require any assembly and just Plugin start Equipment. It Has a Touchscreen PLC Display with 1000 Data storage Facilities. It’s Mostly accurate and has required minimal manual intervention. It also has an inbuilt printer which prints data immediately after the test.
