BRIEF
INTRODUCTION
2MW
type gas turbine, one of the series, is the
item which is recommended by
the state for its energy-saving environmental protection and advanced
technology. It can improve the utility of the surplus coke oven gas, oil field
gas and exhaust gas of oil refinery, especially suiting for coking industry,
petroleum chemistry, oil field and so on . Through
over twenty years development, gas turbine sets have operated approaching five
hundred thousand hours by now. The power station in The comprehensive heat efficiency of gas turbine set is 30 percent higher than that of steam turbine set and the pay back period is 50 percent shorter. The facts have shown, 2MW gas turbine is a mature, stable, reliable, energy-saving product with evident social and economic beneficial results. CHAPTER 2 PRINCIPLES OF 2MW GAS TURBINE CO-GENERATION POWER STATION OPERATION The
gas turbine is started by a starting motor. When it reaches the ignition speed,
the compressed air is mixed with the fuel gas for combustion within the
combustor. The combustion gas with high temperature and high pressure from the
gas generator will drive the power turbine to work. When the running speed of
the set reaches 42 percent of its rated speed, the starting motor will be
automatically disengaged from the set. When the set runs automatically to its
balance speed, the electric generator
which is driven by power turbine will rotate at the same speed and
operate in parallel with network. Fuel supply and output power increase in
accordance with a certain law, the rated load of the set is 2000KW. Exhaust flow
of gas turbine is 16.6Kg/s with 400℃.0.8-1.2Mpa
vapour with the flow of 6.5t/h is produced by the heat recovery boiler, the
boiler exhaust temperature is 190℃.Heat-electricity
co-generation is realized by the packaged set with its comprehensive heat
efficiency reaching 70 percent or higher . CHAPTER 3PERFORMANCE PARAMETER●

CHAPTER 4 REQUIREMENT FOR QUALITY OF FUEL AND WATER ●
Requirement
for fuel (for example coke-oven gas ) When
calorific value is 17.9MJ/Nm3 (not less than 15.9MJ/Nm3 )
●
Requirement
for the quantity and quality of water
Cooling water is used by circulation, water exhausted amount is 2t/h in
practice.
In
order to prolong the life of the boiler, the requirement for water quality
shall meet the international standard. CHAPTER
5 CONTROL
FOR ENVIRONMENTAL PROTECTION ●
Noise
control Noise
of inlet and exhaust air is disposed by filter silencer in gas turbine unit,
Noise meet the international specification. ●
Vibration control Isolation
measure is adopted in gas turbine unit and compressor to control the vibration. ●
Discharge
control Fuel
is burnt thoroughly , not causing draining pollution; exhaust temperature of
boiler is 190℃,
not causing heat pollution. CHAPTER
