5E-C5508 Automatic Oxygen Bomb Calorimeter

1. Application

5E-C5508 Automatic Oxygen Bomb Calorimeter is used to determine the calorific value of solid and liquid combustiles including oil, coal, coke, foodstuffs, SRF and biomass products. The calorific value is a crucial characteristic for each substance, also the key point to calculate the price of coal, so it will directly affect the economic benefits of the customers. This technique is widely applied in power plants, coal mines, metallurgy, chemical industry, commercial inspection, scientific research, etc.

2. Features

a. True Isoperibol Calorimeter

The jacket surrounding the vessel is kept at constant temperature with an accuracy to 0.1℃ during analysis.Mechanical supports for the vessel are made of a very lowthermal conductivity plastic. To minimize convention,water is added on the sides,top and bottom of the bucket.

b. High Automation and Efficiency

(1) 10 minutes analysis time by dynamic method, without compromising accuracy or precision.

(2) Optional second bomb operation minimizes down-time because the second bomb and sample can be prepared while the current sample is being analyzed.

(3) Two calorimeters can be controlled by one computer.Sample mass can be transferred to PC directly.

c. Optimized Design for Reliable Test Result

(1) A reliable quantitative measuring cup ensures stable water volume of the bucket.

(2) Closed-loop water circulation assures the purity of water system without any additional solution.

(3) Filter in the bucket purify the water in circulation system.

(4) Visible water level indicates the water volume, making it easy to feed sufficient water anytime to minimize the influence of water loss.

d. Oxygen Automatic Filling System

To speed uo and simplify the bomb's oxygen filling, the 5E-C5508 Calorimeter has an automatic system for chargng the bomb with oxygen. Oxygen from a commercial cylinder which is connected to a micro-processor controlled solenoid installed in the calorimeter.

e. Full Automatic Operation System

To minimize the total analysis time, with full automated lowering of the vessel. while filling the bucket from the measuring cup. This allows optiomal circulation of water for boosting productivity.
