Product Description

GDY-1A+ Automatic bomb calorimeter for measuring cross calorific value of solid and liquid samples


The instrument is designed and made according to GB/T213-2008 Method for the determination of the calorific value of coal, GB/T384-1988 Method for the determination of the heat value of petroleum products and Calibration and Inspection Regulation of People's Republic of China JJG672-2001 Oxygen Bomb Calorimeter, as well as the Shanghai Enterprise Standard Q/YXYY 10 GDY-1 Oxygen Bomb Calorimeter.

1. In a sealed metal container that is submerged in water in an insulated container, the reaction occurs in a bomb calorimeter. The water in the sealed container receives heat from the reaction as it passes through its walls. Similar to a coffee cup calorimeter, the water's temperature differential is measured. Because heat flow into the metal components of the calorimeter must be taken into consideration, the analysis of the heat flow is a little more difficult than it was for the coffee cup calorimeter.

q_reaction = - (q_water + q_bomb)

where q_water = 4.18 J/(g·°C) x m_water x Δt
 

2. The bomb has a fixed mass and specific heat. The mass of the bomb multiplied by its specific heat is sometimes termed the calorimeter constant, denoted by the symbol C with units of joules per degree Celsius. The calorimeter constant is determined experimentally and will vary from one calorimeter to the next. 

q_bomb = C x Δt
 

3. Knowing the calorimeter constant makes estimating heat flow easy. During a reaction, the pressure within a bomb calorimeter frequently fluctuates, which means that the heat flow could not be of comparable size to the enthalpy change.

Features

1. The instrument uses single-chip technology, an LCD display, a temperature sensor with excellent precision, and a high-performance A/D converter. That is an extremely intelligent tool.

2. The entire testing process is automated. The instrument will complete every step without any operator intervention after the sample is placed and the appropriate parameters are entered. After the test is finished, the test data will be printed.

3. This device uses an oxygen bomb that is sealed. The entire construction is made of stainless steel. Under room temperature, the strength is sufficient to withstand a 20 MPa hydrostatic test.

4. The inner water container is constructed of stainless steel and has a pear-shaped section. It has a 3000g water capacity and an electric stirrer to maintain a constant temperature in the water bath.

5. There are two containers in the external water jacket. When being tested, it will be completely filled with water, and the water jacket's stirrer will work to maintain the required constant temperature and uniform temperature.
