Abstract

The invention discloses a control system and a control method of residual fuel burning in a supply pipeline of a gas generator set. The control system comprises a fuel feeding system power supply, an ignition system, a cooling and lubricating system and a start-up system power supply, and the fuel feeding system power supply, the ignition system, the cooling and lubricating system and the start-up system power supply are independently managed. The control method particularly comprises closing the fuel feeding system power supply firstly, stopping fuel feeding for a generator while guaranteeing a generator set to remain in operation, consuming fuel in the supply pipeline until the generator stops rotating, enabling power generation voltage of the generator to be lower than 40V, and then closing the other equipment. Therefore, sufficient burning of the residual fuel in the supply pipeline can be guaranteed, and corrosion of gas on the pipeline and fuel supply pipeline damage caused by the fuel expanded by heating are avoided.

Description

The control system and the method for the burning of fuel gas generation unit service residual fuel
Technical field
The present invention relates to fuel gas generation unit control field, be specifically related to a kind of control system and method for fuel gas generation unit service residual fuel burning.
Background technique
In the fuel gas generation machine set system,, be diffused in the air, thereby might lead to a disaster because fuel is promptly gasifiable at normal temperatures.For avoiding the generation of accident, the main switch solenoid valve of the fuel supply system of fuel gas generation unit, the mounting point causes electromagnetic valve outlet to cylinder certain distance to be arranged often near gas holder; After the fuel gas generation unit was shut down, electromagnetic valve outlet had a large amount of gaseous states or liquid fuel in the fuel supply pipeline between the cylinder.And this part fuel, except that the fuel supply pipeline is had the corrosive action, its pressure also can change with peripheral temperature, possibly damage the fuel supply pipeline, leads to a disaster then.
Summary of the invention
The present invention is directed to the defective of existing technology; Aim to provide a kind of control system and method for fuel gas generation unit service residual fuel burning; It can consume generator set fuel supply pipeline residual fuel with simple method, avoids combustion gas that Corrosion of Pipeline and fuel expanded by heating are caused the fuel supply piping failure.
It is realized based on following technological scheme:
First aspect present invention provides a kind of control system of fuel gas generation unit service residual fuel burning; Comprise fuel supply system power supply, ignition system, cooling and lubrication system and start-up system power supply, and said fuel supply system power supply, ignition system, cooling and lubrication system and start-up system power supply are managed independently.
Second aspect present invention provides the controlling method of a kind of fuel gas generation unit service residual fuel burning, comprises each constituent element in the control system of above-mentioned fuel gas generation unit service residual fuel burning, specifically may further comprise the steps:
S1: close the fuel supply system power supply, stop fuel being provided to generator set;
S2: generator set relies on the interior residual fuel of fuel supply pipeline to remain in operation, and residual fuel is exhausted in the fuel supply pipeline;
S3: close ignition system, cooling and lubrication system and start-up system power supply;
And the basis for estimation that the residual fuel burning finishes in the said fuel supply pipeline is that motor stops operating, and generator for electricity generation voltage is lower than 40V.
The control system and the method for said fuel gas generation unit service residual fuel burning provided by the invention, it closes the fuel supply system power supply earlier, stops fuel to generator being provided; But keep generator set to remain in operation simultaneously; Make it consume the fuel in the service, stop operating until generator, and the generating voltage of generator is lower than 40V; Close other equipment again; So, can guarantee that the residual fuel in the service fully burns, avoid combustion gas that Corrosion of Pipeline and fuel expanded by heating are caused the fuel supply piping failure.
Embodiment
Further specify technological scheme of the present invention through embodiment below:
The control system of said fuel gas generation unit service residual fuel burning comprises fuel supply system power supply, ignition system, cooling and lubrication system and start-up system power supply.
And said fuel supply system power supply, ignition system, cooling and lubrication system and start-up system power supply are managed independently.
The controlling method of said fuel gas generation unit service residual fuel burning comprises each constituent element in the control system of above-mentioned fuel gas generation unit service residual fuel burning, specifically may further comprise the steps:
S1: close the fuel supply system power supply, stop fuel being provided to generator set;
S2: generator set relies on the interior residual fuel of fuel supply pipeline to remain in operation, and residual fuel is exhausted in the fuel supply pipeline;
S3: close ignition system, cooling and lubrication system and start-up system power supply;
And the basis for estimation that the residual fuel burning finishes in the said fuel supply pipeline is that motor stops operating, and generator for electricity generation voltage is lower than 40V.
The control system and the method for said fuel gas generation unit service residual fuel burning provided by the invention, it closes the fuel supply system power supply earlier, stops fuel to generator being provided; But keep generator set to remain in operation simultaneously; Make it consume the fuel in the service, stop operating until generator, and the generating voltage of generator is lower than 40V; Close other equipment again; So, can guarantee that the residual fuel in the service fully burns, avoid combustion gas that Corrosion of Pipeline and fuel expanded by heating are caused the fuel supply piping failure.
Above the present invention has been carried out exemplary description; Obvious realization of the present invention does not receive the restriction of aforesaid way; As long as the various improvement of having adopted technological scheme of the present invention to carry out; Or design of the present invention and technological scheme are directly applied to other occasion without improving, all in protection scope of the present invention.
