Description
Technical field
The present invention relates to a kind of turbine, specifically a kind of turbine for installing boiling rotor and stator blade cleaning device additional.
Background technology
Metallurgy iron industry makes full use of the energy for maximum benefit now, and power cost saving is most of to be sent using BPRT
Wind system or TRT systems, a large amount of coal gas with pressure energy and heat energy for making full use of blast furnace to produce, are expanded by turbine and produced
Raw mechanical energy, then by speedup clutch direct connection fan or direct connection generator.The grid-connected low energy coal of low energy coal gas after expansion
Gas net is sent into gas fired-boiler and burnt with air stoichiometry, and boiler produces Steam Actuation turbine LP rotors and generated electricity, or steam turbine warp
Cross clutch speed reducer and sintering smoking blower fan is direct-connected.Or steam feeding user warms oneself and heat effect.Using the method not
Only environmentally friendly and energy-conservation.Although blast furnace gas dust content is controlled within claimed range, saturated water content is very high in coal gas,
Coal gas temperature after one-stage expansion does work is greatly lowered, and gas condensed water is produced a lot, is produced with the mix dust in coal gas
Raw mud, then mud is easily bonded on blade when promoting the acting of two grade blades, because motive force is very big, causes adhesive force very strong,
It is difficult to get rid of, although the equipment having provides soft water water injection system for oneself, but effect is not good, two grade blades are caused to promote the dirt of face bonding
Uneven distribution, turbine rotor vibration is increased, to ensure that safe operation must periodically be shut down, and is removed Shang Gai, is held cylinder；Rotor is transported to
High-speed balancing does in producer, and otherwise rotor oscillation oversteps the extreme limit when requiring 8 road, will occur the pernicious safe thing of fatal crass
Therefore, economy and society name acoustic effect two is lost greatly.The orderly closedown time between overhauls(TBO) is five months, minimum 20 days of repair time, daily
Turbine off-stream mostly occurs 30,000 yuan of electricity charge for AV50 blower fans, amounts to 600,000 yuan of the electricity charge that mostly occur within 20 days；The cost of overhaul 15
Wan Yuan；Binomial is total 750,000 yuan.It is annual to amount to 1,500,000 yuan of loss.It is smelting that dispelling for dirt is bonded on turbine rotor movable vane piece
The a great problem of golden industry.
