Abstract
To eliminate necessity of air fans and thus simplifying equipment by adding air branched from an air compressor into oxygen-containing high- temperature exhaust gas from a gas turbine and supplying a gas mixture thus obtained to a late-stage furnace or a hearth for oxygen-containing combustion. A portion of the air supplied into an air compressor 1 via a conduit 2 is guided outside via a conduit 18 after a first stage compression in the air compressor 1 and added to exhaust gas guided from a gas turbine 7 via a conduit 9. A gas mixture thus formed is delivered as the gas for oxygen- containing combustion to pyrolysis furnaces A to F through a conduit 12. Further, an air flow branched from the air compressor 1 is further rendered to flow through an heat exchanger 19 disposed in midway of the conduit 18, so that it can be warmed before its mixing with the exhaust gas from the gas turbine 7 through the conduit 9. Therefore, equipment cost can be reduced due to simplification of devices without needing additional air fans.

The present invention relates to a kind of in each stove of commercial plant or combustion furnace, particularly olefin hydrocarbon apparatus the method for pyrolysis oven supplying oxygen-containing combustion air, wherein contain oxygen waste gas and the air of sneaking into is made combustion-supporting gas with the high temperature of combustion gas turbine.
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 oxygen and aiding combustion gas combustion produced indirectly.Combustion gas turbine waste gas mixes mutually with air and gives pyrolysis oven as combustion-supporting gas in the gas turbine system that is mainly become by air compressor, gas generator and work turbine mechanism, with the combustion medium that burns, and with this turbine drives generator.In view of not containing desired oxygen content in the combustion-supporting gas in the combustion gas turbine waste gas,, mix mutually with the waste gas of combustion gas turbine so, adopt an air blast to send into air in order to satisfy needs to institute's anoxic gas.So oxygen containing combustion-supporting gas is 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 combustion-supporting gas 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 combustion-supporting gas 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 combustion-supporting gas 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 mixing combustion-supporting 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 combustion-supporting 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 combustion-supporting gas 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 combustion-supporting gas 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 combustion-supporting gas 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 combustion-supporting gas 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 combustion-supporting gas 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:
