Electricity generation boiler system.
Background technology
Because the discharge of the efficiency, reduction pollutant that improve generating set is an eternal topic, therefore some are new general
Ideo-motor Force system is paid close attention to.The physical property of supercritical carbon dioxide is special, and under identical burden requirement, work is used as using it
The electricity generation system of matter is smaller, more compact structure, can save floor occupying area, reduce cost, simultaneously because its energy density
It is bigger than water, it is more efficient as the steam generator system of working medium using supercritical carbon dioxide in the case of existing steel high temperature resistant level.
Under the background of carbon dioxide discharge-reduction, as collecting carbonic anhydride, research on utilization go deep into, it will help faced with super
Boundary's carbon dioxide is the development of the electricity generation system of working medium.Retrieve Patents and find that there is presently no collecting carbonic anhydride, profit
With the case being combined together with the electricity generation system using supercritical carbon dioxide as working medium, as patent 201610038208.1 is a kind of
Coal base supercritical carbon dioxide Brayton cycle double split flow efficient power generation system, a kind of 201510117556.3 Novel supercriticals two
Carbonoxide coal-burning boiler.
In supercritical carbon dioxide double reheat coal-fired electric generation furnace system implementation process, hot working fluid again sometimes be present
The problem of temperature overheating degree is not up to standard.For this problem, solution of the prior art is as follows：Patent of invention
201610654055.3 a kind of supercritical carbon dioxide Boiler radiation heated surface arrangement method, it is in hearth combustor lower disposed
Reheating working medium radiation heating-surface, the method for arranging main working medium radiation heating-surface in burner peripheral region and upper area, it is not
Foot part is：Can only realize that single reheat is done work, can not double reheat acting, and cascaded utilization of energy rate is low, causes energy
Amount wastes；A kind of Novel supercritical carbon dioxide coal-burning boiler of patent of invention 201510117556.3, its be horizontal furnace structure and
It arranges the attached wall radiation cooling heating surface of three ranks in burner hearth, and it is disadvantageous in that：On the one hand, three ranks is attached
The ratio of wall radiation cooling heating surface and position be it is certain, its be unable to burning inside flexible adaptation different load lower hearth and
Heat transfer situation, spirit can not be carried out to the degree of superheat deficiency problem of single reheat working medium and double reheat working medium under different load
Regulation living, on the other hand, horizontal furnace structure has the defects of its is intrinsic, flue gas stream bottom horizontal flow sheet and thermal current can be spontaneous upward,
