DIGITAL BOMB CALORIMETER
Used for determination of combustion of heat of colorific value of the fuel
Accuracy +- 200-250cal/gm (5% Approx)
SPECIFICATION:
Bomb Calorimeter Apparatus 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 All parts of the outfit have been finished and tested according to the specification laid down by Institute of petroleum and British Standard Institute.
INTRODUCTION
TESTING OF BOMB
Each Bomb is tested before it leave the factory in accordance with requirements of the institutes of petroleum (I.P.12/63T Appendix 1)and works certificate is issued with each Bomb . This certificate gives the results of hydraulic testing under a pressure no 300 atmospheres (400p.s.i) maintained for a period of ten minutes without sign 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. 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 outside and S.S. The top is closed by an ebonite cover. A terminal block is fitted to the top container so that connection can be made from the control.
OFFSET STIRRER
The stirring mechanism supplied gives sufficient turbulence for effective stirring whilst no heat 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 bell precludes any possibility of heat transference between motor and calorimeter vessel contents.
ELECTRONIC FIRING UNIT WITH DIGITAL BACKMAN THERMOMETER
The firing a calorimeter Bomb AC supply main 230 Volts 50 AC supply. It consists of two parts VIZ 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 the test of firing wire resistance or open circuit.
