Description
[technical field]
The invention belongs to energy-conserving and emission-cutting technology field, be related to a kind of host low pressure (LP) cylinder zero that can reduce cold source energy contribute it is cold
But vapour system and method.
[background technique]
In recent years, the new energy electric powers installed capacity such as wind-powered electricity generation, photovoltaic, water power maintains sustained and rapid growth, and provides a large amount of cleanings
Electric power.But because of the randomness and unstability of its generated output, it is unfavorable for the large-scale grid connection of clean energy resource, existing electric system
Regulating power is difficult to adapt to new energy extensive development and consumption completely, and some areas more serious abandonment occur, abandon light
With abandoning water problems.Therefore it needs that the peak modulation capacity of electric system is promoted and extended, so as to cleanings energy such as wind-powered electricity generation, photoelectricity
Bigger space is vacateed in source.
Still mainly based on thermoelectricity, in order to promote the peak modulation capacity of electric system, abandoning light is effectively relieved in generation current unit
Rate abandons light rate, promotes renewable energy digestion capability, it is necessary to set about from Thermal generation unit, further promote coal electric generator
The peak modulation capacity of group, could solve the contradiction between peak modulation capacity and heat demand conscientiously.
In many promotion unit flexibilities, the technology for solving peak load regulation scarce capacity, the power output of host low pressure (LP) cylinder zero is supplied
Hot scheme is because its cost of investment is low, the transformation period is short, flexible operation is widely adopted.Under conditions of heating load is constant, host
Zero power output technology of low pressure (LP) cylinder can reduce unit generation power, realize depth peak regulation, dissolve new energy electricity for power grid and provide space,
It is insufficient to solve fired power generating unit peak modulation capacity, alleviates power grid abandonment, abandon optical issue.
The key of the power output technology of host low pressure (LP) cylinder zero is to cut off host low pressure (LP) cylinder original steam inlet pipe road into vapour, passes through newly-increased other
Road pipeline is passed through a small amount of cooling steam, rotates the air blast generated for low pressure rotor after taking away the power output transformation of host low pressure (LP) cylinder zero
Heat.The flow of cooling steam can be variant for different units, during actual use generally it is not less than 20t/h, it is cold at present
But the source of steam is directly derived from intermediate pressure cylinder steam discharge.It is right since the main function of cooling steam is cooling host low pressure (LP) cylinder rotor
Steam parameter does not have particular/special requirement, and cooling effect is mainly influenced by cooling steam flow size.And intermediate pressure cylinder exhaust steam pressure and temperature
Spend parameter it is higher, still have very strong acting ability, into host low pressure (LP) cylinder cooling steam under the influence of blasting action,
It can not effectively do work, it is only simple for cooling down host low pressure (LP) cylinder rotor, cause a large amount of high temperature and high pressure steams acting abilities damages
It loses, it will cause additional cold source energy.
