Description
Technical field
The invention belongs to boiler plant field, and in particular to a kind of low capacity boiler reheated steam multitube bypass temperature adjustment system
System, the reheat steam temperature for low capacity boiler is adjusted.
Background technology
With environmental protection and the continuous improvement of energy-saving and emission-reduction requirement, low capacity boiler high parameterization band reheat system will be future
One trend of boiler industry development, for example, had producer super with 220t/h, 130t/h, 110t/h HTHP and high temperature
Reheating steam system is used in the small-capacity generator group of high-pressure boiler, but is limited by various factors such as production run, technologies,
The fluctuation of low capacity boiler load is big, working conditions change is frequent, therefore reliable reheat steam temperature regulating system is to ensure whole machine
The essential condition of group normal table work.
Under declared working condition, in order to ensure reheated steam quality, reheater water injection desuperheater spray amount is steamed no more than reheating
The 2% of steam flow amount, only steam side temperature adjustment can not meet the demand of reheat steam temperature regulation；Steamed to more effectively regulate and control reheating
Stripping temperature, boiler for high power station typically adjusts reheat steam temperature using the method for flue gas bypass, but low capacity boiler is restricted
In the factor influence such as exhaust gas volumn is small, flue gas flow deviation big, flue gas flow area is limited, cigarette is easily produced using flue gas by-pass method
Gas bias current, can produce very big thermal deviation, be difficult to control, fume side thermoregulation effect is undesirable.Therefore, how effectively reliably to enter
The regulation of row reheat steam temperature turns into the key factor of small-load generators development of the restriction with reheat system.
The content of the invention
It is an object of the invention to there is provided a kind of low capacity boiler reheated steam multitube bypass temperature adjustment system regarding to the issue above
System, realizes the reliable adjustment to low capacity boiler reheat steam temperature, can effectively solve low capacity boiler load and fluctuate big, regulation
Frequently, using the bias current of fume side temperature adjustment means it is serious, it is whard to control the problem of.
The present invention is achieved like this, low capacity boiler reheated steam multitube bypass thermoregulating system, mainly including low temperature
Reheater, high temperature reheater, reheater water injection attemperator, low-temperature reheater steam by-pass pipe, electric gate valve, mixing header, subtract
Warm water regulating valve, emergency spray attemperator, low-temperature reheater import header, low-temperature reheater outlet header, high temperature reheater enter
Mouth header and high temperature reheater outlet header；It is characterized in that：The emergency spray attemperator being connected with steam turbine is distinguished by pipeline
The low-temperature reheater steam by-pass pipe that low-temperature reheater import header and more than three are connected in parallel is connected to, low-temperature reheater enters
Mouth header connects up low-temperature reheater, and low-temperature reheater connects up low-temperature reheater outlet header, low-temperature reheater outlet
Header is connected to reheater water injection attemperator by pipeline, and reheater water injection attemperator is connected to high temperature reheating by mixing header
Device import header, high temperature reheater import header connects up the high temperature reheating of connection above high temperature reheater, high temperature reheater

Electric gate valve is housed on header, every low-temperature reheater steam by-pass pipe；Desuperheating water passes through the water pipe equipped with Desuperheating water regulating valve
It is respectively connecting to emergency spray attemperator and reheater water injection attemperator.
The reheated steam extracted out from steam turbine cylinder, two-way is divided into after emergency spray attemperator, reheater is introduced all the way
Import header, separately leads up to low-temperature reheater steam by-pass pipe, the mixing header introduced behind direct-contact desuperheater；Major part is again
Vapours enters low-temperature reheater import header, after being heated through low-temperature reheater, and reheating is introduced by low-temperature reheater outlet header
Device direct-contact desuperheater, the steam after spray cooling flows into mixing header；Remaining sub-fraction reheated steam is through emergency spray
After attemperator, mixing header is introduced directly into by low-temperature reheater steam by-pass pipe, the part height with flowing through low-temperature reheater
Warm steam is sufficiently mixed, and reduces the reheat steam temperature of high temperature reheater entrance, prevents that high temperature reheater outlet steam temperature from surpassing
Go out；Reheated steam after the blended further desuperheat of header, heats into high temperature reheater through high temperature reheater import header, reaches
To after nominal steam temperature, turbine low pressure cylinder acting is introduced through main-steam outlet valve by outlet header；The low-temperature reheater
Steam by-pass pipe just, pass-out steam flow is adjusted by the quantity of open and close electric gate valve according to reheated steam outlet temperature,
Realize the regulation to reheat steam temperature；It is described that the main method for regulating temperature that temperature adjustment is reheated steam, spray are bypassed by reheated steam
Water temperature reducing regulation is only auxiliary adjustment, during boiler operatiopn, after reject steam desuperheat, is become according to reheater main-steam outlet temperature
Change, the injection flow rate of direct-contact desuperheater is controlled by Desuperheating water regulating valve, carry out micro auxiliary adjustment, system is only carried out in steam side
Temperature is adjusted, it is not necessary to set adjusting means again in fume side；The emergency spray attemperator only breaks down in steam turbine, reheating
Inlet steam temperature is used when exceeding design load.
Further, above-mentioned low capacity boiler reheated steam multitube bypass thermoregulating system, the mixing header is using set
Tubular construction, it is to avoid cold fluid and hot fluid directly contacts header body, produces heat fatigue and damages；The low capacity boiler reheated steam
Multitube bypasses thermoregulating system, illustrate only the main building block and adjusting means of system, should also include composition system pipeline,
Measurement apparatus and other necessary valves.
Further, above-mentioned low capacity boiler reheated steam multitube bypass thermoregulating system, in order to preferably control bypass
The flow of steam, the caliber of described low-temperature reheater steam by-pass pipe is different, by the combination of different tube diameters pipeline, full
Sufficient boiler adjusts the demand of reheat steam temperature under different operating modes.
It is to solve small-load generators reheat steam temperature using the steam side method for regulating temperature of steam by-pass combination spray desuperheating
The effective way of reliable adjustment.Reheat system drag overall loss is smaller, typically requires that boiler body reheater SR is little
In 0.15MPa, the regulation to steam flow on bypass line causes larger difficulty, and regulating valve resistance cannot act as greatly very much bypass
The regulation of steam flow, triple valve resistance is smaller, still can not meet requirement, and triple valve it is expensive be unfavorable for product into
This control.Bypass line adjusts steam flow using the folding of multi-pipeline gate valve, and resistance is small, cheap, meets systematic function
Requirement, can be realized with reference to spray desuperheating and reheat steam temperature is continuously adjusted.
The solution have the advantages that：Thermoregulating system is bypassed by low capacity boiler reheated steam multitube, efficiently solved
The problem of regulation of low capacity boiler reheated steam is difficult, there is that simple system, bypass pipe resistance be small, easily operated, temperature adjusting performance
Reliable the advantages of.
