3. Technical characteristic:
Because was used double press boiler, can drop boiler exhaust temperature, improve boiler efficiency thereby, if low-pressure vapour parameter rises, can enhance turbine power, but temperature of boiler smoke evacuation rises accordingly, rate of utilization of waste heat is reduced; If low-pressure vapour parameter is low, absorb quantity of heat much, vapour amount is large, after entering turbine, electricenergy production increases, rate of utilization of waste heat increases, temperature of boiler smoke evacuation is reduced accordingly; But after entering turbine, the demand of the bulk to turbine and end class lamina can rise further, additionally the circular water quantity of condenser is about to increase, increase a factory to use n thereby. Because this requires a basis plant layout, optimize systematic parameter design, choose optimal parameter thereby.
Kiln end the structural characteristic of more than heat boiler: More than heat boiler takes ① kiln remaining part drum, set evaporator and superheater, flue gas flows outside the canal, heating surface is snakelike smooth canal, make sure with specific technology boiler check avoids those who suffer flue gas grain to erode, wear away reach corrode, contain dirt gas in order to prevent high speed high temperature to cause an effect to the tenacity of convection check, intensity, wearability; ② installs machine brace up the dust that hits device to settle waste gas is adherent problem; ③ boiler heating surface is decorated reasonable.
Kiln head the structural characteristic of more than heat boiler: (1) . Make sure with specific technology boiler check avoids those who suffer flue gas grain to erode, wear away reach corrode, contain dirt gas in order to prevent high speed high temperature to cause an effect to the tenacity of convection check, intensity, wearability; , assure the heat exchange efficiency of boiler; (2) . Reasonable decorate boiler heating surface, make smoke evacuation thermal drop is controlled to 95°C; (3) . In kiln head in more than heat boiler, because waste gas dust is clinker grain, adhesiveness is not strong, remove dust means uses nature to sedimentation; It is additionally increase heating surface area, effect of aggrandizement heat exchange, kiln head of more than heat boiler conduct heat tubal design is helix wing piece canal.
Use filling steam to coagulate steam type turbine. According to systematic characteristic, undertake parameter is optimized, reasonable and affirmatory double press parameter of vapour of more than heat boiler, turbine advocate vapour and filling steam parameter, thereby the structure of reasonable design turbine and filling steam dot; Its regulating system uses electro-hydraulic adjustment, automation rate is high; Turbine rotate speed uses 3000r/min, need not decelerate machine, reduce breakdown point. Because structure of filling steam type was used on turbine, can make low-pressure vapour is saturated vapour enters turbine business even, increase the electricenergy production of turbine thereby.
