Research On Boiler Performance Test Data Processing System Development

Boiler performance tests as the basis of the performance qualification tests and acceptance tests of boiler, is one of the boiler thennal efficiency of boiler assessment will do the test. Based on a point of order, there are two kinds of GB/T10184-1988"power station boiler performance testing procedures and the American Society of Mechanical Engineers ASME PTC4-2008" boiler performance testing procedures. Main measurement of main parameters of the steam temperature, pressure, flow, exhaust gas temperature, air temperature and flue gas analysis, sampling of pulverized coal ash sampling and other secondary parameters, the use of input-output heat method and heat loss method to calculate the boiler thermal efficiency.Based on the above considerations, I developed a boiler performance test data processing system. Consists of three parts:The first part is the data acquisition system based on Yokogawa MV2000Paperless Recorder, do the circuit transformation, automatic measurement can capture48signals can either collect the thermocouple signal, can also be collected EMISSION MGA5the flue gas analysis system and the HFM-215multi-point heat flow meter of oxygen, carbon dioxide, nitrogen oxides and heat flow coming from the4-20mA signal. The second part is the data transmission communication system. Advanced Ethernet interface of client/server system to support the FTP protocol, the measurement data to a PC. Transmission mode can be selected according to the scene of a wireless router to connect wired router to connect and network cable directly connected to three kinds. The third part is the software analysis of computing systems, programming with Visual C++6.0. To achieve the deviation limit, the calculation of the uncertainty of the measurement data processing in each test item, to boiler performance calculations.
