By the EP0122534 European patent specification, for example known a kind of method that is used to make the olefin hydrocarbon apparatus operation of cracked hydrocarbon, when wherein preparing alkene in cracking or the pyrolysis oven hydrocarbon heat by containing the heat that the burning of oxygen burning gases produced indirectly.One is mainly mixed mutually with air by combustion gas turbine waste gas in air compressor, gas generator and the gas turbine system that constitutes as turbine and gives pyrolysis oven as burning gases, with the combustion medium that burns, and with this turbine drives generator.In view of not containing desired oxygen content in the burning gases in the combustion gas turbine waste gas, so in order to satisfy needs, adopt an air blast to send into air, with the needs of the waste gas of combustion gas turbine to institute's anoxic gas, adopt an air blast to send into air, mix mutually with the waste gas of combustion gas turbine.So oxygen containing burning gases are made up of following two parts: the waste gas of combustion gas turbine and pass through the air blast inhaled air.
The article of " energy consumption of the comprehensive minimizing ethene factory of combustion gas turbine " has been delivered and be entitled as to " oily gentle magazine " 55-60 page or leaf that John V Alba promise and Edward F Ao Erce Paderewski were published on February 10th, 1992, set forth these class methods in this paper equally.
In view of the shutdown of combustion gas turbine or gas turbine system or cut off the burning gases supply that will certainly influence the pyrolysis oven that is connected on thereafter, so olefin hydrocarbon apparatus is equipped with an emergency system that is used for pyrolysis oven is carried burning gases usually.Emergency system can be made of the above-mentioned air blast of having mentioned, and the configuration of this air blast should be able to be satisfied the requirement that when combustion gas turbine is shut down air is increased.Usually also can in device, prepare one or more air blast for the shutdown of the combustion gas turbine that may occur.
The task that the present invention is rely to the basis is, a kind of method of mentioning when this paper begins is provided, and utilizes the method to guarantee conveying to the burning gases of stove or combustion furnace in simple mode.Wherein both consider normal operating condition, also attached the emergency operating state of having considered when combustion gas turbine is shut down simultaneously, made every effort to reduce the equipment cost of device.
This task of the present invention is to adopt following scheme to solve: distribute the air in the combustion gas turbine compressor, make it to mix mutually with the waste gas of combustion gas turbine, and flow to stove or the combustion furnace that is connected on the back as mixed combustion gas.
According to the present invention, needed air is not to adopt the method for prior art to be provided by an independent air blast when normally moving, but provide by the combustion gas turbine compressor.Wherein needed amount of fresh air preferentially behind preceding several compression stages of combustion gas turbine compressor, is also just said with low relatively pressure and is shunted, and mix in the turbine exhaust gas of turbine outlet.
Therefore the present invention will simplify stove greatly, pyrolysis oven in the olefin hydrocarbon apparatus particularly, but also comprise the air supply of other combustion furnace.
Useful especially is, the air that distributes by the combustion gas turbine compressor be preheated before combustion gas turbine waste gas mixes.Therefore, can improve the burning gas temperature of the stove that is connected on the back.
In further improvement of the present invention, when shutting down, combustion gas turbine can supply with stove as burning gases with fresh air, and wherein air is introduced the transfer pipeline that leads to burner via the air valve on the stove.When combustion gas turbine was shut down, the air valve on the stove was opened automatically.In order to make the gas circuit of leading to burner short as far as possible, preferably air valve is configured in the last waste gas distributing pipe highway section of leading to stove.Also can guarantee the continual work of stove all the time like this even when combustion gas turbine is shut down.
Useful is; when combustion gas turbine is shut down; valve on the stove is the connection sealing of the burning gases intake line that is used for the normal operation of stove; that is to say, the intake line of when normal operation, making the gaseous mixture that burning gases air and combustion gas turbine waste gas that adopt, that distributed by the combustion gas turbine compressor forms and waste gas distribution circuit be connected by stove on the valve of close burner closed.If be both the connection blocking-up that these valves both can lead to the burning gases in normal when operation the stove intake line, can be used as air valve simultaneously again and open the air that leads to stove and carry, just more useful.What in this case, air valve stoped simultaneously the required burning gases of normal operation again imports the residual exhaust gases of being deposited from its intake line.Except that this bifunctional valve, can also add the pure air valve that adopts other, thereby guarantee stove is carried enough combustion airs.
The present invention is further elaborated by the contrast of the method example of the embodiment of the inventive method and prior art below.
Shown in the accompanying drawing:
