Our NEW COSA XENTAUR™ 9800CXi™ Calorimeter is a fast response, injection-style zero-hydrocarbon emissions calorimeter. It can provide direct measurement of Calorific Heating Value and BTU with a measurement range 0-3000 BTU/scfh. A real advantage with the 9800CXi calorimeter is that it can handle high sulfur concentrations with an H2 measurement option.
An injection-style zero-hydrocarbon emissions calorimeter is a specialized instrument used for measuring the calorific value of fuels and other combustible materials without emitting any hydrocarbons into the environment. It works by injecting a small sample of the material into a combustion chamber where it is burned, and measuring the heat produced by the combustion reaction.
Unlike traditional calorimeters that require the use of a constant flow of hydrocarbon fuel for ignition and operation, an injection-style zero-hydrocarbon emissions calorimeter uses an alternative ignition system that doesn’t produce hydrocarbon emissions. This allows for a more environmentally friendly testing process and eliminates the need for additional hydrocarbon fuels to operate the calorimeter.
Key advantages to using our measuring principle, based on the Residual Oxygen Measurement Method, are its insensitivity to changes in ambient temperature, very fast response times with the ability to measure BTU values down to zero. A small constant volume of sample gas is injected into a continuous flow of combustion air with each measurement cycle, providing a precisely maintained fuel/air ratio profile. The fuel air mixture is oxidized in the combustion furnace at 1000°C, and the residual oxygen concentration of the combustion sample is measured by a zirconia oxide sensor. The residual oxygen provides an accurate method of measuring Heating Value with optional measurement of Wobbe Index correlated to Specific Gravity of the sample gas. Higher temperature reduces maintenance of the instrument; varying temperature up to 1000°C.

The 9800CXi calorimeter is a highly sensitive instrument used for measuring the calorific value of liquid and gaseous fuels. It is commonly used in industries where accurate measurement of the calorific value of fuels is critical. Some of the industries that use this calorimeter include:
The 9800CXi calorimeter uses a patented heat flow principle to directly measure the heat of combustion of a gas sample. This is achieved by igniting the gas sample in an insulated combustion chamber, and then measuring the heat released during combustion.
The instrument measures the temperature rise of a cooling fluid that surrounds the combustion chamber and calculates the heat of combustion based on the amount of heat transferred from the combustion chamber to the cooling fluid. The amount of heat transferred is directly proportional to the calorific heating value of the gas sample.
The 9800 CXi calorimeter also measures the volume of gas consumed during combustion, allowing for the calculation of the BTU value of the gas sample. The BTU value is calculated by dividing the calorific heating value of the gas sample by the volume of gas consumed during combustion.
