Abstract
The invention relates to the technical field of boilers, in particular to a control method for improving economical operation of a boiler charge returning air blower, comprising the following steps: A. deploying three charge returning air blowers (NO.1, NO.2 and NO.3), operating the NO.1 charge returning air blower when the boiler operates normally and leading the rest of the two charge returning air blowers for standby application; B. presetting an exit wind pressure set value at the exit of each charge returning air blower of the boiler; C. installing pressure sensors at the exit of each returning air blower of the boiler, calculating the exit wind pressure mean value of each returning air blower measured by a pressure sensor and comparing the mean value with the set value; and D. initiating the NO.2 charge returning air blower if the mean value is less than the set value. By utilizing the control method for improving economical operation of boiler charge returning air blower, control logic of the operation of the air blowers is optimized, the purposes of saving energy and reducing energy consumption are achieved, and the control objective of safe operation is realized, thus realizing the control logic of leading one charge returning air blower into operation and the rest of the two charge returning air blowers for standby application.
Description
Technical field
The present invention relates to the boiler technology field, particularly relate to a kind of controlling method that improves the economical operation of boiler returning charge blower fan.
Background technique
The returning charge blower fan of circulating liquid fluidized bed boiler generally is designed to dual-purpose one and is equipped with, and is capable according to a dual-purpose received shipment, though safety coefficient is higher, cost also increases thereupon, can not reach energy saving purposes.In fact separate unit is counter expects that blower fan just can satisfy burden requirement as long as move, the dual-purpose one that all requires according to boiler producer when but the control commissioning staff designs anti-material blower fan control logic is equipped with the controlling schemes programming, just move the separate unit blower fan under the situation of not revising control logic, operation risk is bigger.If returning charge blower fan tripping operation, the operations staff is not instant to find that the returning charge blast is reduced to 20KPa under within one minute, directly influence the returning charge effect of material returning device, can cause that bed temperature rises rapidly, the consequence of burner hearth coking.
Summary of the invention
The objective of the invention is to avoid deficiency of the prior art and a kind of controlling method that improves the economical operation of boiler returning charge blower fan is provided, can realize the economical operation that a usefulness two is equipped with, can guarantee security of operation again.
Purpose of the present invention realizes by following technical measures.
A kind of controlling method that improves the economical operation of boiler returning charge blower fan, step comprises:
A. dispose three returning charge blower fans, be respectively No. one, No. two and No. three, when boiler normally moves, move No. one the returning charge blower fan, all the other two returning charge blower fans are standby;
B. preset the outlet blast setting value in every returning charge blower fan of boiler outlet port;
C. in every returning charge blower fan outlet port of boiler pressure transducer is set, and calculates the outlet blast mean value of each returning charge blower fan that described pressure transducer measures, described outlet blast mean value and described outlet blast setting value are compared;
D. if outlet blast mean value less than outlet blast setting value 20KPa, then starts the returning charge blower fan No. two.
Preferably, if an operating returning charge blower fan is out of service, then start off-duty No. three returning charge blower fans.
The controlling method of raising boiler returning charge blower fan of the present invention economical operation has been optimized the control logic of fan operation, can reach energy saving purposes, can realize the control target of safe operation again, has realized the control logic that a usefulness two is equipped with.
Description of drawings
Fig. 1 is the system schematic of one embodiment of the present of invention.
Embodiment
The invention will be further described with the following Examples.
An embodiment of the controlling method of raising boiler returning charge blower fan of the present invention economical operation, step comprises:
A. dispose three returning charge blower fans, be respectively returning charge blower fan 1, No. two returning charge blower fans 2 and No. three returning charge blower fans 3, when boiler normally moved, it was standby to move 1, No. two returning charge blower fan 2 of a returning charge blower fan and No. three returning charge blower fans 3;
B. preset the outlet blast setting value in every returning charge blower fan of boiler outlet port;
C. in every returning charge blower fan outlet port of boiler pressure transducer is set, and calculates the outlet blast mean value of each returning charge blower fan that described pressure transducer measures, described outlet blast mean value and described outlet blast setting value are compared;
D. if outlet blast mean value less than outlet blast setting value 20KPa (can be set up on their own by the operations staff), then starts returning charge blower fan 2 No. two; If an operating returning charge blower fan 1 is out of service, then start off-duty No. three returning charge blower fans 3.
Should be noted that at last; above embodiment only is used to illustrate technological scheme of the present invention but not limiting the scope of the invention; although the present invention has been done detailed description with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement technological scheme of the present invention, and not break away from the essence and the scope of technical solution of the present invention.
Claims (2)
1. controlling method that improves the economical operation of boiler returning charge blower fan, it is characterized in that: step comprises:
A. dispose three returning charge blower fans, be respectively No. one, No. two and No. three, when boiler normally moves, move No. one the returning charge blower fan, all the other two returning charge blower fans are standby;
B. preset the outlet blast setting value in every returning charge blower fan of boiler outlet port;
C. in every returning charge blower fan outlet port of boiler pressure transducer is set, and calculates the outlet blast mean value of each returning charge blower fan that described pressure transducer measures, described outlet blast mean value and described outlet blast setting value are compared;
D. if outlet blast mean value less than outlet blast setting value 20KPa, then starts the returning charge blower fan No. two.
2. the controlling method of raising boiler returning charge blower fan according to claim 1 economical operation is characterized in that: if an operating returning charge blower fan is out of service, then start off-duty No. three returning charge blower fans.
