Problems solved by technology
[0003] Generally, traditional combustible gases are measured by chromatography. Although chromatography is accurate in analyzing combustible gases, the analysis time of chromatography is long, and the measured values are all staged, which cannot quickly reflect the gas component value. At the same time , The instrument sampling system has no redundancy and poor sampling reliability. The measured data after the instrument fails may affect the stable operation of the unit. The calculated calorific value of the fuel is relatively single, without other references. It is difficult to find instrument faults, and the calorific value monitoring is not perfect and reliable.

The invention discloses an IGCC combined cycle power generation fuel component analysis and calorific value measurement system, which can effectively measure fuel components through the infrared instrument as the main method and the chromatographic instrument as a backup; multiple redundant measurement combination, syngas sampling It is divided into two groups, and the measuring instruments are equipped with two groups. The introduction of multi-channel calculation of calorific value not only improves the reliability of calorific value control, but also can effectively find measurement and process failure problems through calorific value comparison. In the state of instrument failure, Ensure effective output calculation value, improve the accuracy of calorific value calculation, accurately analyze fuel components, calculate fuel calorific value, ensure the stability of calorific value adjustment system, and ensure the stable operation of gas turbine combustion. More security and the introduction of the comparison between the measured calorific value and the calculated calorific value can not only effectively monitor the calorific value change, but also monitor the equipment status.
Description
technical field [0001] The invention relates to the technical field of IGCC coal chemical industry, in particular to an IGCC combined cycle power generation fuel component analysis and calorific value measurement system. Background technique [0002] Compared with the traditional coal-fired and gas-fired power generation mode, the IGCC combined cycle power generation mode selects syngas as the fuel. However, due to the complex components of the syngas, the change of the proportion of each component will affect the change of the calorific value, so the fuel composition measurement and The calculation of calorific value is of great significance to the stable operation of IGCC combined cycle power generation. IGCC combined cycle power generation fuel components mainly include: H 2 , CO, CO 2 , CH 4 , N 2 , H 2 O, although the calorific value gas is mainly: H 2 , CO, CH 4 , but N 2 , H 2 The content of O also has a great influence on the calculation of the calorific val...
