Abstract: An IGCC fuel component analysis and calorific value measurement system, the fuel components can be effectively measured by an infrared instrument and a chromatographic instrument; the multiplex redundant measurement is combined, two syngas is sampled by two sampling devices, two groups of measuring instruments are arranged, the multi-channel calculation of calorific value improves the reliability of calorific value control, and the measurement and process problems are effectively found by calorific value comparison, guaranteeing the effective output of calculated values in the fault state of the instrument, improving the calculation accuracy of calorific value, accurately analyzing the fuel components and calculating the fuel calorific value, and ensuring the stability of the calorific value regulation system and the stable operation of gas turbine; the multi-directional, diversified and multi-security instrument and the introduction of comparison between measured and calculated calorific values can effective

Abstract: A new hammering system with electromagnetic power for dynamic pile testing. The basic working principle of the hammering system is as follows: when an internal coil is energized, a magnetic force is generated to attract tightly, via a magnetic conduction panel, an adaptive weight hammer disposed in contact with the surface of the panel; when the internal coil is de-energized, demagnetization occurs, and the weight hammer falls instantaneously to impact the pile top, thereby achieving the effects of a stable weight hammer and quick attraction and falling of the hammer. A clamping scale is arranged inside an adjustment section of a guide frame. A falling height of the weight hammer may be selected arbitrarily.
