XRY 1A Digital Coal Oxygen Bomb Calorimeter

Product Overview

Description

XRY-1A Digital Coal Oxygen Bomb Calorimeter 

Summary

The instrument is designed and made as per the National Standard of People’s Republic of China GB/T213-2008 and ASTM D240 Test Method for Calorific Value of coal, GB/T384-1988 Test Method for Calorific Value of Petroleum Products and Calibration Regulation of People’s Republic of China JJG672-2001 Oxygen Bomb Calorimeter, as well as Enterprise Standard of Shanghai Q/YXYY 10 XRY Series Oxygen Bomb Calorimeter.

The heat capacity of the instrument is 14000 J/K~15000 J/K, and it is suitable for determining the calorific value of combustible materials such as petroleum products without water (gasoline, jet fuels, diesel oil and fuel oils, etc.), coal, coke and paraffin, etc.

 

I. Main technical features

1. This instrument adopts a sealed oxygen bomb. The whole structure adopts stainless steel material. The strength is enough to resist the max pressure (60~70 atmospheric pressure) when the solid is burning. And it can resist the bigger pressure when liquid fuel burns.

2. The inner water cylinder is composed of a stainless steel sheet. The cross section is pyriform and the capacity is 3kg. The water cylinder is equipped with an electric stirrer inside. It ensures the temperature in the water cylinder is uniform.  

3. The external water jacket is a double-layer container. It filled with water when doing determination. It makes the water temperature in the cylinder uniform by the water jacket stirrer and forms a constant temperature environment meeting the requirements of the test.
