Abstract
The utility model relates to a gas-turbine device using oil-refining lean gas, which belongs to the power devices. The utility model is composed of a gas turbine and a screw compressor connected with a combustion chamber of the gas turbine. The low-pressure oil-refining lean gas passes through the screw compressor to improve the pressure, and then the low-pressure oil-refining lean gas can be used as the fuel of the gas turbine.
Description
The utility model relates to power plant, particularly a kind of gas turbine installation that uses the oil refining dry gas.
At present, factory of petrochemical refining wants association to go out a certain proportion of oil refining dry gas in the oil refining production process.Produce about 70,000 tons of the oil refining dry gas that 2,000,000 tons oil refining apparatus institute association goes out per year as a cover.These 70,000 tons oil refining dry gas are used for gas turbine power generation, and its electric power can reach 38000kw.Simultaneously the exhaust gas heat of gas turbine also can be used for exhaust heat boiler and reclaims, exhaust heat boiler can produce under without the situation of fuel 67 tons of the middle pressure steams of 3.9MPa/450c/time.And factory of existing petrochemical refining generally can only make fuel usefulness in the in-plant various stoves to the oil refining dry gas of association.But its consumption is less, and a large amount of unnecessary dry gas can't utilize, and can only slattern with " day lamp " burning back emptying.The oil refining dry gas of association is a kind of low-pressure gas, the about 0.006MPa of its pressure, but the suction pressure of gas turbine need be greater than 1.8MPa, and the dry gas of therefore refining oil can not directly enter gas turbine and use.
The purpose of this utility model is to design a kind of gas turbine installation that can use the oil refining dry gas, utilizes the fuel of the oil refining dry gas of low pressure as gas turbine, and energy saving cuts the waste, and benefits the people.
The technological scheme that the utility model is taked is: the association of low pressure oil refining dry gas is boosted by helical-lobe compressor, it is brought up to greater than 1.8MPa by 0.006MPa use for gas turbine.
Advantage of the present utility model: with an oil refining dry gas of producing 2000000 tons oil refinery institute association per year is example for 70,000 tons, these 70,000 tons of dry gas can get the 38000kw electric power by gas turbine power generation, with 0.4 yuan of calculating of every degree electricity price, 12,160 ten thousand yuan of RMB are then amounted in combustion machine year work 8000 hours.And the waste heat that the combustion machine is discharged by exhaust heat boiler also can produce 67 tons of the medium pressure steams of 3.9MPa/450c/time.Steam per ton is amounted to 2,680 ten thousand yuan of RMB with 50 yuan of calculating.Combustion machine work 8000 hours consume 5,600 ten thousand yuan of fuel costs, then year economic benefit is about 8,000 ten thousand yuan.Oil refining dry gas as all factories of petrochemical refining of the whole nation can both develop, and its economic benefit and social benefit are very big.
The utility model can also obtain further instruction from the following drawings and embodiment:
Fig. 1 is the utility model general illustration.Among the figure:
1, gas compressor 2, firing chamber 3, turbo machine
4, generator 5, helical-lobe compressor 6, exhaust heat boiler
See also shown in Figure 1: the utility model is a kind of gas turbine installation that uses the oil refining dry gas, by gas compressor 1, and firing chamber 2, turbo machine 3 and helical-lobe compressor 5 are formed.Connecting screw rod compressor 5 before the firing chamber 2 of combustion machine.Low pressure oil refining dry gas is introduced into helical-lobe compressor 5 and compresses.Dry gas pressure after being compressed enters 2 burning backs, firing chamber greater than 1.8MPa and promotes turbo machine 3 runnings.
The utility model is associated with generator 4 and exhaust heat boiler 6.Gas turbine is except that generating, and exhaust heat also can produce generating of steam steam supply turbine generator group or heat supply in exhaust heat boiler.
