Digital Bomb Calorimeter
Bomb Calorimeter Outfit provide a simple and inexpensive method for
determination of heat of combustion of organic matter and the calorific
value & sulphur content of solid & liquid fuel. The outfit
supplied is complete for analysis as per the method recommended by
British Standard Institution BS 1016. All parts of the outfit have been
finished and tested according to the specification laid down by
Institute of petroleum and British Standard Institute.
Testing of Bomb :
Each Bomb is tested before it leaves the factory in accordance with the
requirement of the Institute of Petroleum (I.P. 12/63 T.Appendix 1) and
a works certificate is issued with each Bomb. This certificate gives
the results of hydraulic testing under a pressure of 300 atmospheres
(4400 p.s.i) maintained for a period of ten minutes without sign of
leakage. The maximum deformation must not exceed the specified limits. |
Calorimeter Vessel :
The vessel is made of copper and is Chromium plated or S.S. It includes
a Bomb support that ensures proper positioning of Bomb in the vessel. |
Water Jacket :
The outer container of Jacket is made of copper and is chromium plated
both inside and outside or S.S. The is closed by an ebonite cover. A
terminal block is fitted to the of the container so that connection can
be made from the firing control. |
Offset Stirrer :
The stirring mechanism supplied gives sufficient turbulence for
effective stirring whilst no heat is imparted to the calorimeter water.
It consists of an impeller stirrer driven at a constant speed of
approximately 800 r.p.m. The offset arrangement whereby the motor
drives the impeller via a belt precludes any possibility of heat
transference between motor and calorimeter Vessel Contents. |
Electronic Firing Unit with Digital Backman Thermometer :
For firing a calorimeter Bomb AC supply main (230 Volts 50 Cycles). It
consists of two parts Viz Electrical Box and Electronic Box for Digital
Thermometer reading. The Electrical Box is provided with socket for
stirrer and terminals for the fuse wire. The unit has provision for
test of firing wire resistance or open circuit. A left hand side bulb
indicate the continuity while right hand side bulb indicates the open
circuit (firing). |

Crucible :
Various types of crucible are available the standard supplied with the
outfit being a stainless steel crucible of 8 ml capacity which fits in
the standard support ring provided with the outfit. |
