Abstract
The invention discloses a steam cooler with a heater and a working method of the steam cooler. The steam cooler comprises a pipeline with an exhausted steam inlet, and devices at a cooler side and a heater side, wherein the devices are arranged at two ends of the pipeline. According to the invention, the steam cooler and the heater are combined into a whole, thus greatly reducing occupation area and being convenient for arrangement; and exhausted steam of a turbine enters the cooler, firstly part of supplied water is heated, meanwhile the exhausted steam is cooled, and the cooled exhausted steam spreads to the heater via a pore plate to further heat equipment supplied water, thus realizing the function of an original heater. According to the invention, the function of the steam cooler can be realized, and the original heater can be replaced, thus having dual functions; and when the steam cooler is used, an emergency drain pipeline of the original heater can be used without needing independent arrangement of an emergency drain pipeline for the steam cooler.
Description
Technical field
The invention belongs to thermal power generation unit draw gas and heater system optimization field, be specifically related to a kind of steaming cooler with heater
And method of work.
Background technology
Owing to the degree of superheat of thermal power plant's reheating embrittlement regenerative steam is relatively big, the irreversible loss produced in heat transfer process is the biggest.It is most
May reduce this loss, existing reforming mode is increase externally arranged steam cooler on the corresponding extraction line of unit, and steam cools down
Device is positioned on extraction line, and part feedwater enters boiler after steam condenser is heated, draws gas simultaneously and enters heating after being lowered the temperature
Inside device.On the one hand this mode properly increases the temperature of part feedwater, reduces effective heat transfer temperature difference of boiler, increases boiler efficiency,
Improve the heat-economy of unit；On the other hand reduce the degree of superheat of steam, namely reduce heat transfer temperature difference, improve unit further
Heat-economy.But increase externally arranged steam cooler at extraction line, not only individually to buy steam condenser, and owing to entering
The change of vapour parameter, high-pressure heater originally is the most undesirable, needs to buy new heater and changes.Meanwhile, the cloth of pipeline
Put difficulty to increase, the mainly emergent drain pipeline of steam condenser, cause system complexity to be greatly increased, it is contemplated that cost expenses
Reaching more than 1,000 ten thousand, cost is too high.
Summary of the invention
It is an object of the invention to overcome above-mentioned deficiency, it is provided that a kind of steaming cooler with heater and method of work thereof, it is possible to will add
Hot device and steaming cooler combine, and greatly reduce cost.
In order to achieve the above object, a kind of steaming cooler with heater, including cooler side and heater side, cooler side and adding
Hot device side connects by offering the lateral steam tube road of extraction entrance, and cooler side hydroecium offers feed-water inlet and feedwater outlet, and leads to
Crossing the first hydroecium dividing plate to separate, connected by U-tube between feed-water inlet and feedwater outlet, heater side hydroecium offers heating
Device water inlet and heater outlet, and separated by the second hydroecium dividing plate, pass through between heater water inlet and heater outlet
U-tube connects, and U-tube is placed in lateral steam tube road.
It is provided with the first orifice plate between the hydroecium of described cooler side and lateral steam tube road, is provided with between the hydroecium of heater side and lateral steam tube road
Second orifice plate.
Described extraction entrance is positioned close on the lateral steam tube road of cooler side.
The U-tube length of described cooler side is less than the U-tube length of heater side.
The U-tube of described cooler side and the U-tube of heater side are many groups.
A kind of method of work steaming cooler with heater, comprises the following steps:
Step one: draw gas and enter in lateral steam tube road from extraction entrance, carry out heat exchange with the feedwater in the U-tube of cooler side,
Drawing gas and lowered the temperature, feedwater enters boiler internal by pipeline after heating up；
Step 2: drawing gas after cooling is freely spread to heater side and heats the water inlet in the U-tube of heater side, adds
Heater water outlet after heat enters low-level device.
Compared with prior art, steaming cooler and heater are united two into one by the present invention, substantially reduce floor space, and are easy to cloth
Putting, the entrance cooler that draws gas of steam turbine, heating part feedwater, drew gas simultaneously and was lowered the temperature before this, and drawing gas after cooling passes through orifice plate
It is diffused into the water inlet of heater further firing equipment, it is achieved the effect of former heater, the present invention can not only realize the work of steam condenser
With, moreover it is possible to substitute former heater, there is dual-use function, and when using this equipment, it is not necessary to individually arrange for steam condenser
Emergent drain pipeline, uses the emergent drain pipeline of former heater.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the present invention.
Detailed description of the invention
The present invention will be further described below in conjunction with the accompanying drawings.
See Fig. 1, a kind of steaming cooler with heater, lead to including cooler side and heater side, cooler side and heater side
Crossing the lateral steam tube road connection offering extraction entrance 3, cooler side hydroecium offers feed-water inlet 1 and feedwater outlet 2, and passes through
First hydroecium dividing plate 6 separates, and is connected by U-tube between feed-water inlet 1 and feedwater outlet 2, and heater side hydroecium offers
Heater water inlet 4 and heater outlet 5, and separated by the second hydroecium dividing plate 9, heater water inlet 4 and heater
Being connected by U-tube between outlet 5, U-tube is placed in lateral steam tube road, arranges between the hydroecium of cooler side and lateral steam tube road
Having the first orifice plate 7, be provided with the second orifice plate 8 between the hydroecium of heater side and lateral steam tube road, extraction entrance 3 is positioned close to cooling
On the lateral steam tube road of device side, the U-tube length of cooler side is less than the U-tube length of heater side, the U-tube of cooler side
It it is many groups with the U-tube of heater side.
A kind of method of work steaming cooler with heater, comprises the following steps:
Step one: draw gas and enter in lateral steam tube road from extraction entrance 3, carry out heat exchange with the feedwater in the U-tube of cooler side,
Drawing gas and lowered the temperature, feedwater enters boiler internal by pipeline after heating up；
Step 2: drawing gas after cooling is freely spread to heater side and heats the water inlet in the U-tube of heater side, adds
Heater water outlet after heat enters low-level device.
The present invention is by steam condenser and heater integration, and an equipment achieves the function of two equipment, need not be separately provided steaming
The emergent drain pipeline of vapour cooler, simplifies pipe arrangement, and improvement cost is substantially reduced, and can reduce by 10% according to preliminary estimation.
