  • Application of Frequency conversion in Induced Draft fan and energy saving analysis
    Hunan Electric Power, 2007
    Co-Authors: Yuan Shao-qu
    Abstract:

    The basic principle of variable frequency speed regulation technology for Draft fan in power plant and ZINVERT high voltage frequency conversion system were introduced and applied in modification of Induced Draft fan of No.1 boiler in Ruiming power plant.The energy-saving effects before and after variable frequency control applied in Induced Draft fan were analyzed and compared.The results indicated that frequency conversion technology had great advantage in energy-saving and improving automatic control level.

  • modelling of a dual circuit Induced Draft cooling water system for control and optimisation purposes
    Journal of Process Control, 2015
    Co-Authors: Cornelius Jacobus Muller, I K Craig
    Abstract:

    Abstract The successful operation of any petrochemical plant is dependent on the use of several utilities which may include electricity, steam, compressed air, cooling media, refrigeration media, nitrogen, condensate and fuel gas. These utilities form a significant portion of the fixed cost associated with running a plant. Utility optimisation has not received much attention until recently, driven by rising energy costs, stricter environmental policies, more competitive markets, and the threat of climate change. The generation, preparation, and transportation of utilities require energy and therefore should be optimised to reduce losses and improve operating efficiency. One example of such a utility is a cooling water system. This paper describes the modelling of a dual circuit Induced Draft cooling water system for control and optimisation purposes. The derived model is verified with plant data indicating promising results. The model is represented in a steady-state algebraic form as well as a dynamic state-space form. This provides a convenient basis for simulation studies and controller/optimiser design.

  • Application of turbine-driven Induced Draft fan in 1000 MW ultra-supercritical unit
    Electric Power, 2012
    Co-Authors: Yao You-jiang
    Abstract:

    For energy-saving and emission-reducing,enhancing the efficiency of energy utilization,the technological innovation for Induced Draft fan with the maximum power in 1 036 MW ultra supercritical unit of Huaneng Haimen Power Plant was implemented.Changing general motor-driven Induced Draft fan to turbine-driven mode for the first time,merger setting the Induced Draft fan and the FGD booster fan,not setting FGD booster fan alone,the power plant using electricity rate was obviously reduced.And 6 kV power of the auxiliary power system was reduced.The Induced Draft fan can realize variable speed adjustment,and the loss of throttling was reduced,the energy-saving effect was remarkable.The operation of the Induced Draft fan driven by turbine was stable,the function of furnace pressure adjustment was good,and which can satisfy the index request of Induced Draft fan performance under full load condition.
