9800CXi Calorimeter
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.
The 9800CXi calorimeter Wobbe Index measurement is based on the analysis of the oxygen content in the flue gas after combustion of the sample. A continuous gas sample is mixed with dry air at a precisely maintained constant ration, which depends on the BTU range of the gas to be measured. The fuel air mixture is oxidized in a combustion furnace in the presence of a catalyst at 800’C, and the oxygen concentration of the combusted sample is measured by a zirconia oxide cell. The residual oxygen provides an accurate measurement for the Combustion Air Requirement (CARI) of the sample gas, which can be correlated accurately to the Wobbe Index of the gas.
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 9800 CXi 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 the 9800 BTU Calorimeter include:
