1.1 The Basic Situation and Different Type of China's Power Plants

Power Production Structure

Since 1996China's power production and consumption

has accounted for second in the world.

(1Installed capacity

1949 1,850 MW

consumer.

(2) Level of technological development

Unit capacity :Develops from 6MW to 1000MW

Pressure level:From pressure (3.83MPa) to

ultra-supercritical ( 27MPa)

Equipment :The manufacture domestically, achieves the

world advanced level

Main: Thermal power

Include: coal-fired power plant, the comprehensive utilization power plant, coal-water slurry power plant etc.

Other: hydropower, nuclear power, new energy

New energy sources including wind power, biomass power generation, rubbish power generation, solar power, etc.

1.2 Development Background of Comprehensive Utilization Power Plant

Damage That The Coal Reject and The Coal Slime Dump on The Spot

The Use of Coal Reject and Coal Slime

China's energy structure

The coal is China's primary energy, in 2007 China's coal

output has reached 2526Mt.(ranking first in the world)

The coal reject and the coal slime are coal mining or wash out the reject

which in the process discharges. If the local stackthen 1Takes the massive lands2Produce environmental pollutioninfluence production and the

resident live

- The coal reject can have the spontaneous combustion.

- The coal slime meet the wind namely to blow off, to meet the water is

the outflow, stops up the river course.

- The output is big, the pollution is more serious

1The coal reject and the coal slime are the useful resourcesThe Coal reject and the coal slime have certain calorific value The

calorific value is different, the use way is differentthereinto coal slime: Generally the calorific value is high Can be used forpower generation.

NO. Categories

Gas Turbine Generator Set

Principle: Gas burns in combustion chamber, flue gas enter into gas

turbine to work and drive generator to generate electric.

RequestGas Concentration60

Stable Heat Value and High Inlet Pressure

Principle: Gas burning in body internal, flue gas push cylinder piston

to move and drive generator to generate electric.

Advantage: The request for gas concentration is low, can be > 6%.

Principle: The same as normal power plant: boiler + steam turbine,

gas as the fuel

Request: Gas Concentration>30%, Stable Heat Value
