The TR-9200 series of coke-oven, gas stove, hot stove gas analysis system is specifically designed to reduce the pollution of the gas emissions, improve combustion efficiency and recovery of sensible heat, improve product quality and the purpose of the analysis system, because of the Coke Oven Gas flue gas, coke dry quenching gas, gas furnace gas, hot stove furnace gas, measured an indecent contain tar, dust, low boiling point organic compounds, H2S and other sulfur material or water vapor to varying degrees, a high viscosity, easy to crystallize, corrosive characteristics, it is complex, gas composition analysis system could easily lead to clogging, corrosion. In response to the above, we use a variety of new technologies targeted design of the system is safe, reliable, corrosion-resistant, non-clogging, sampling real quick response and analysis of high precision, configuration and selection of the best lot of features. 
 Coke oven gas, also known as coke oven gas. Refers to the preparation of several bituminous coking coal, coke oven dried at high temperatures 
 Distillate, while coke output [wiki] [/ wiki] and tar products produced by a combustible gas, a byproduct of the coking industry. 
 Coke oven gas is a mixture, the yield and composition of the different quality of coking coal and coking process conditions, 
 Generally ton of dry coal to produce coke oven gas 300 ~ 350m3 (standard state).

 TR-9200 The system is designed for electric fishing device coke gas components on-line continuous detection of the O2 content in well-designed supporting an electrical instrumentation. Set of machines, electrical, instrument in one, with high reliability class of sensors, advanced measurement techniques and sophisticated sample pretreatment combining to form a functional, safe and reliable, little maintenance, easy to operate, the use of life long process analysis system. The system adopts international advanced class sampling and pretreatment technology for the purification and processing of coke oven gas tar, coal dust, water vapor and naphthalene, hydrogen sulfide and other corrosive substances, to ensure the long-term on-line analytical instruments run. Compared with similar products with high technical advantages and cost advantages. 
 Scope of application: 
 This device is suitable for various types of electric fishing focus control and various types of furnace gas pipeline oxygen content measurements by automatic analysis of the oxygen content, the safety interlock control devices. 

 Analysis to control the composition and functions of the device 
 The device, electrical, instrument integration complete set of analytical control device. The entire device, including by the analysis of cabinet components (internal sample purification unit, control unit purge and analysis proofing units, etc.) and installation of special sampling device components in the process piping composition. 
 Dedicated sampling devices: the intrinsically safe explosion-proof. Purification unit for all stainless steel samples. In addition to naphthalene for the harsh working conditions contained in the coke oven gas harmful ingredients is extremely complex, with international advanced vortex control cold tar removal, sampling the clean primary treatment, in addition to water vapor and dust filtration technology. 
 Analysis of cabinet components: analysis of the cabinet with positive pressure pneumatic explosion-proof structure. 
 The analysis of the cabinet contains the following modules: 
 Pretreatment unit: special liquid filter (sink, fog filter, in addition to sulfur device equivalent components to complete the purification of the composition of the tar, naphthalene, and other middle-class purification; peristaltic row by the condenser, pump, flow separation control of fine filter to complete the fine level of purification treatment; made of special corrosion-resistant pump, flow controller composed of a steady flow of gas and regulator of the sample taken to ensure that the coke oven gas to purify the sample step by step, dust removal, in addition to a series of links of the wet, regulators, steady flow, the filtration precision of up to 0.1μ will meet the requirements of the measured sample into the analytical instruments to ensure the accuracy of the analytical instruments and long-term reliability. 

 Analysis of control interlock unit: oxygen content of the sample gas line completed by the oxygen analyzer and continuous analysis of continuous output 4-20mA signal. The oxygen analysis instrument with alarm output contacts can be set within the range of alarm and interlock value, the alarm and interlock when the content of O2 concentration overrun.
