Gasifier Burner Cooling Water Monitoring System Optimization

Our abundant coal resources, the relative lack of oil and gas resources, increasing demand for clean energy, the coal chemical industry in this emerging industry has been a rare opportunity for development. The basic conversion process is the gasification of coal chemical industry, coal gasification and decide whether the stable operation of the key factors is the life of the burner, the burner operation of the cooling water system monitoring is not in place, the burner can easily cause rupture caused accidents, do burner cooling water system monitoring and management has important practical significance to the field of gasification.The primary means of gasification burner cooling water monitoring is to determine whether there is water cooled CO, CO to prove if there is a cooling water coil burners have led to the furnace gas into the cracks, the need to avoid a major accident promptly discontinued. But with increasing device uptime, online CO analyzers are often false alarms and faults, causing the operator can not correctly judge the current burner operation, only to rely on laboratory analysis work site sampling inspection, manual measurement of the timeliness of poor data unable to guide production. In this paper, Texaco gasifier burner cooling water monitoring system analysis, design optimization, the traditional single burner cooling water system corresponding single set of online CO analyzer mode is improved by increasing the specially modified six through the switching valve system, supporting the installation of the pipeline, enabling online CO analyzers three gasifier burner system for online switching problem solving monitor fault line analyzers, and switching control line analyzer study Through the use of PLC programming and configuration king preparation of PC interface to achieve burner cooling water system monitoring requirements.Subject to the existing online program designed CO analyzers were fully utilized in very small increase in the cost basis of greatly improving the reliability of the online instrument to solve the reliance on manual detection alarm occurs after laborious and time-poor, and there are security risks issues, and through optimized PC interface, a comprehensive analysis of theburner cooling water flow, temperature and pressure monitoring and management for the burner operation provides a better basis to ensure the stable operation of the gasifier.
