Abstract
The utility model discloses a boiler heating starting drive of thermal power factory, including heating a plurality of boilers that the header reached and the heating header links to each other, all boilers insert stove water pump header, and a plurality of circulating water pump are put through to stove water pump header, have resistance heater in the pipeline of every circulating water pump connection, and the pipeline that is equipped with resistance heater inserts water -cooling wall next part case entirely. This boiler heating starting drive of thermal power factory provides the vapour source by cold re -heater, and the enrichment flows to water -cooling wall heating boiler in water -cooling wall next part case at last after the heating.
Description
Technical field
This utility model relates to heat power plant boiler transformation field, is specifically related to a kind of firepower and sends out
Boiler of power plant heating starting device.
Background technology
General boiler is during ignition trigger starts gradually to boost, owing to boiler needs to put into necessarily
Doses combustion burning, radiant heat in burner hearth increases, superheater and each parts of reheater, especially
It is that the burner hearth inner parts such as panel superheater, Late reworking, wall reheater are in dry-fire condition, this
Time each components interior need exist for media flow and protect, and the circulation of the water at ignition trigger initial stage is also
Not completely setting up, the protection to each system just has certain difficulty.Fa Er power plant is original design anhydrous
The bottom steam heating system of cold wall system, during boiler cold-state ignition trigger, burner hearth temperature
Spend low, coal dust be not easy to catch fire need consume great amount of fuel oil to improve fire box temperature, cause fire coal,
Increasing considerably of amount of fuel.Also result in the situation of boiler cold-state starting ignition time length, right
In adapt to dispatching of power netwoks and energy-conservation be a unfavorable factor.Meanwhile, along with international energy situation
Anxiety is gradually increased with energy-saving and emission-reduction pressure, and the cost pressure of power generation is also embodying day by day,
Reduce power plant startup fire coal, fuel oil consumption seems and is necessary.
Utility model content
This utility model aims to provide a kind of heat power plant boiler heating starting device, at four
Increase a heating header between stove, use 4 stoves mutually for heating the thinking in steam supply vapour source,
It is provided as adding hot vapour source with cold reheater, utilizes the feature of boiler water circulating pump at each water of delivery side of pump
One resistance steam heater is installed on pipeline, easy for installation and steam homogeneous heating, respectively manages
The vibration little, that produce of channel temp deviation is the least.
This utility model is achieved by following technical solution:
A kind of heat power plant boiler heating starting device, including heating header and with heating header
If the dry boiler being connected, all boilers access stove water pump header, and stove water pump header connects some
Water circulating pump, has resistance heater in the pipeline of every water circulating pump connection, heats equipped with resistance
The pipeline of device accesses water-cooling wall lower header entirely.
Every water circulating pump is all connected with two parallel pipelines.
Resistance heating it is mounted in two pipelines that every water circulating pump port of export is connected in parallel
Device.
Described heating header opposite side accesses some vapor sources.
On the pipeline that described boiler is connected with stove water pump header, stop valve and electronic two-way are installed
Regulation valve.
The beneficial effects of the utility model are:
Compared with prior art, a kind of heat power plant boiler heating that this utility model provides is opened
Dynamic device, has the advantage that
1, water temperature in drum and water-cooling wall can be brought up to 160 DEG C and more than, at this moment burner hearth is
Have uniform temperature, restart draw, pressure fan meet condition igniting, be conducive to burning, shorten
The time of ignition of the boiler shortens more than 3h, the pressure fan of boiler, air-introduced machine and primary air fan joint
Save operation time more than 2h, save substantial amounts of station service, remarkable benefit.
2, set up water circulation system first to lead in steam heating makes boiler, then put into fuel combustion
Starting trouble, with traditional direct plunge into fuel combustion starting trouble system compared with, to superheater,
Reheater plays certain protective effect.
3, shorten several hours due to the time of ignition of the boiler, save in start-up course each
The power consumption of favourable turn and fuel consumption, save substantial amounts of fuel oil, save startup time, furnace bottom
Steam-heating system has significant energy-saving effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: 1-heats header, and 2-stove water pump header, 3-resistance heater, under 4-water-cooling wall
Header, 5-stop valve, the electronic two regulating valves of 6-, 7-boiler, 8-water circulating pump, 11-steam
Source.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but required
Protection domain be not limited to described；
As it is shown in figure 1, a kind of heat power plant boiler heating starting dress that this utility model provides
Putting, if including heating header 1 and the dry boiler 7 being connected with heating header, all boilers 7 access
Stove water pump header 2, stove water pump header 2 connects some water circulating pumps 8, every water circulating pump 8
Having resistance heater 3 in the pipeline connected, the pipeline equipped with resistance heater 3 accesses water-cooling wall entirely
Lower header 4.
Every water circulating pump 8 is all connected with two parallel pipelines, and shunting is so that steam pressure-reducing subtracts stream.
Resistance heating it is mounted in two pipelines that every water circulating pump 8 port of export is connected in parallel
Device 3, makes steam-energy fully heat in pipeline.
If described heating header 1 side connects dry boiler 7, opposite side accesses some vapor sources 11,
Vapour source (3.53MPa, 316 DEG C) its pressure being provided as heating with cold reheater can meet pot
The drum of stove requires (74304mm).
On the pipeline that described boiler 7 is connected with stove water pump header 2, stop valve 5 and electronic two is installed
Logical regulation valve 6, motor switch, safety and stability.
A kind of heat power plant boiler heating starting device that this utility model provides, by cold reheating
Device provides vapor source, opens each road valve, and steam flows through heating header 1, divides after mix homogeneously
Do not flow through the furnace bottom of all boilers 7, simply heat at the bottom of Boiler Furnace, then flow to stove water pump
Header 2, under the effect of water circulating pump 8, introduces the steam of heat release and adds hot channel,
Water-cooling wall lower header 4 is flowed to, finally after these heating after the heating flowing through resistance heater 3
Steam flow water-cooling wall heating boiler.
