Abstract
The present invention relates to a kind of method that back pressure turbine asynchronous generating unit is run in non-heating period, it comprises the steps：The steam drain of back pressure turbine asynchronous generating unit is connect and leads to drawing gas behind the door for low-pressure heater, when back pressure turbine asynchronous generating unit is run, the steam door of low-pressure heater is closed, the exhaust valve of back pressure turbine asynchronous generating unit is opened, small machine operation is realized.The back pressure unit operation steam discharge that the present invention leaves unused non-heating period Gateway Station in Heating Network connect back into operating unit low plus in, form back pressure unit steam discharge path and send electrical power, exhaust steam heat is recovered in main steam turbine system again simultaneously does not waste, therefore forms the extra extra earning of the generated energy of back pressure unit.
Description
Technical field
The present invention relates to a kind of method that utilization Gateway Station in Heating Network back pressure unit puts into operation in non-heating period, i.e. Gateway Station in Heating Network
The method that back pressure turbine asynchronous generating unit is run in non-heating period.
Background technology
Back pressure unit is commonly installed in Gateway Station in Heating Network, hydraulic recovery generating is carried out using high back pressure small turbine.Back pressure machine
Heating period operation is generated electricity group in the winter time, but as the heat supply in winter phase terminates, back pressure unit is just out of service.Non- heating period
The stoppage in transit of back pressure unit, causes very big waste.
The content of the invention
The present invention is for above-mentioned problems of the prior art there is provided a kind of back pressure turbine asynchronous generating unit non-
The method of heating period operation, solves the wasting problem of non-heating period back pressure unit stoppage in transit in the prior art.
Technical scheme is as follows：
The steam drain of back pressure turbine asynchronous generating unit is connect and leads to drawing gas behind the door for low-pressure heater, when back pressure turbine is different
When walking generating set operation, the steam door of low-pressure heater is closed, the exhaust valve of back pressure turbine asynchronous generating unit is opened, it is real
Existing small machine operation.
Described back pressure turbine asynchronous generating unit is connected to the low-pressure heater of steam inlet condition matching.
Advantages of the present invention effect is as follows：
The back pressure unit operation steam discharge that non-heating period Gateway Station in Heating Network is left unused connect back into operating unit low plus in, form back pressure
Unit steam discharge path sends electrical power, is not wasted while exhaust steam heat is recovered in main steam turbine system again, therefore forms the back of the body
The extra extra earning of the generated energy of press group.
Brief description of the drawings
Fig. 1 is Application Example schematic block diagram of the present invention.
Embodiment
Embodiment
The steam drain of back pressure turbine asynchronous generating unit is connect and leads to drawing gas behind the door for low-pressure heater, when back pressure steamer
When machine asynchronous generating unit is run, the steam door of low-pressure heater is closed, the steam discharge of back pressure turbine asynchronous generating unit is opened
Door, realizes small machine operation.
Described back pressure turbine asynchronous generating unit is connected to the low-pressure heater of steam inlet condition matching.
The application of the present invention is as shown in figure 1, back pressure unit steam discharge parameter is matched with No. 6 low plus steam inlet condition, back pressure machine
180 DEG C of exhaust temperature of group, exhaust steam pressure 0.15MPa, and #6 is low adds 205.51 DEG C of stripping temperature, and initial steam pressure 0.1MPa parameters are more
It is close, therefore the steam drain of back pressure turbine asynchronous generating unit connect lead to drawing gas behind the door for No. 6 low-pressure heaters.
