Abstract
The utility model provides a boiler subtracts warm water water supply system, including inlet tube, water -feeding pump and the main feed pipe that connects gradually, main feed pipe is connected with the water inlet of economizer and desuperrheater respectively through first feedwater branch pipe and second feedwater branch pipe, the delivery port of economizer and desuperrheater is connected with the steam pocket respectively, be equipped with first valves on the first feedwater branch pipe, be equipped with the second valves on the second feedwater branch pipe. The utility model discloses a subtract the accurate control of warm water flow to the boiler -steam dome, the various disturbance factors influence undulant to the steam temperature in the time of can compensating generating set boiler operation guaranteeing that generating set normal operating has effectively improved the generating set efficiency of cycle simultaneously, has realized recycling of the energy, has practiced thrift manufacturing cost.
Description
Technical field
The utility model belongs to boiler plant technical field, relates to a kind of boiler desuperheating water water system.
Background technology
The temperature of generating set power steam directly can have influence on the safety economy stable operation of unit.If the too high thermal stress that can reduce metal of vapor (steam) temperature produced, reduce the service life of unit, threaten the safe operation of unit simultaneously; If the vapor (steam) temperature produced is too low, the thermal efficiency of cycle of whole unit can be reduced, affect the economic indicator of unit.Traditional boiler-steam dome desuperheating water water system attemperation water flow is wayward, causes the temperature fluctuation amplitude of the steam of drum output large, has certain influence to service life of generating set and the thermal efficiency.
Utility model content
The purpose of this utility model is for prior art Problems existing, provides a kind of attemperation water flow to be easy to the boiler desuperheating water water system controlled.
For this reason, the utility model adopts following technical scheme:
A kind of boiler desuperheating water water system, comprise the water inlet pipe, feed pump and the main feed water pipe that connect successively, described main feed water pipe is connected with the water inlet of attemperator with economizer with the second subfeeder respectively by the first subfeeder, and described economizer is connected with drum respectively with the delivery port of attemperator; Described first subfeeder is provided with the first valve group, and described second subfeeder is provided with the second valve group.
Further, described feed pump comprises the first feed pump and the second feed pump, and the first feed pump and the second feed pump are in parallel.
Further, described attemperator is non-contact attemperator.
The beneficial effects of the utility model are: achieve the accurate control to boiler-steam dome attemperation water flow, can the boiler operatiopn of offset electricity generation unit time various disturbance factor impact that steam temperature is fluctuated, normally run at guarantee generating set and effectively improve the generating set efficiency of cycle simultaneously, achieve the recycling of the energy, save production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1-water inlet pipe, 2-first feed pump, 3-second feed pump, 4-main feed water pipe, 5-first subfeeder, 6-second subfeeder, 7-economizer, 8-attemperator, 9-drum, 10-first valve group, 11-second valve group.
Detailed description of the invention
As shown in Figure 1, a kind of boiler desuperheating water water system, comprise water inlet pipe 1, feed pump and the main feed water pipe 4 connected successively, main feed water pipe 4 is connected with the water inlet of economizer 7 with attemperator 8 with the second subfeeder 6 respectively by the first subfeeder 5, and economizer 7 is connected with drum 9 respectively with the delivery port of attemperator 8; First subfeeder 5 is provided with the first valve group 10, second subfeeder 6 and is provided with the second valve group 11; Described feed pump comprises the first feed pump 2 and the second feed pump 3, and the first feed pump 2 and the second feed pump 3 are in parallel.In the utility model, attemperator 8 is non-contact attemperator.
During work, boiler feed water is transported to economizer 7 and attemperator 8 by the first subfeeder 5 and the second subfeeder 6 by the first feed pump 2 and the second feed pump 3 respectively, economizer 7 is delivered to drum 9 after feedwater being heated and is produced steam, attemperator 8 is by exporting to drum 9 temperature that desuperheating water regulates steam in drum 9, economizer 7 exports the flow that the flow of hot water and attemperator 8 export desuperheating water and controls respectively, to realize the accurate control of vapor (steam) temperature in drum 9 by the first valve group 10 and the second valve group 11.
