Description
Technical field
The utility model relates to the effectively power device that the residual heat resources such as a kind of middle high-temperature flue gas reclaim, and is specifically related to one and utilizes 300 DEG C with upper high-temperature flue gas waste heat double-work medium combined cycle generating unit, belongs to field of fluid machinery.
Background technique
In industrial processes, there are a large amount of 300 DEG C of above middle high-temperature flue gas.Conventional flue gas waste heat recovery method at present, the for example application recovery of cement kiln waste heat more widely, be to obtain saturated or superheated vapour by exhaust heat boiler, then water vapor injected in straight condensing turbine or filling condensing steam turbine and expand and do work, and drawing generator generating.In this class device, the pressure and temperature of steam is higher, and the efficiency of turbine thermodynamic cycle is just higher.But because the mass flow rate of working medium in exhaust heat boiler depends primarily on the caloric receptivity of vaporizer (for evaporation of water), due to the restriction of evaporation of water temperature and pinch-point temperature difference, vapor pressure is higher, the caloric receptivity of afterheat boiler evaporator is just less; Compared with vaporizer, the caloric receptivity of economizer (for the heating of liquid water) is very little; Therefore, the temperature of exhaust fume after UTILIZATION OF VESIDUAL HEAT IN is still higher, and utilization rate of waste heat is very low.
Be not difficult to find by above-mentioned analysis, it is the most effectual way that improves heat recovery rate that low-temperature zone after raising afterheat boiler evaporator recepts the caloric, and this is also in current Large Gas-Steam Combined Cycle circulation power station, often to adopt pair pressure or three to press the main reason of exhaust heat boilers.But, for the fume afterheat of single parameter, two pressures or three press the boiler circuit of exhaust heat boiler too complicated, adopt filling condensing steam turbine final vacuum volume flow very large, unit generated output displacement than conventional thermal power steam turbine is high more than 3 times, cause waste heat recovering device bulky, invest also very high.Compared with conventional water vapor Rankine cycle, low boiling organic rankie cycle (ORC) has larger advantage aspect low temperature exhaust heat recovery, not only efficiency is high, and equipment very compact (the working medium density ratio water vapor density of turbine steam-expelling port high 100 by more than, mean its exhaust casing area only need conventional back pressure turbine 1%); But due at high temperature poor chemical stability of organic working medium, easily decompose, the utility model makes full use of the advantage of two kinds of thermodynamic cycles, proposes a kind of new double-work medium combined cycle generating unit, for the high efficiente callback utilization of high-temperature flue gas waste heat.
