Embodiment Construction
[0030] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in various ways defined and covered below.
[0031] Such as figure 1 As shown, the first embodiment of the present invention provides a multi-fuel system, which is used to provide one or more types of fuels with different phases and different calorific values to the combustion chamber of the gas turbine. The range of applicable fuel types is wide and can be used at any time It can switch between multiple fuels anywhere without shutting down for maintenance, and can ensure continuous energy output during the switching process of different fuels. The multi-fuel system includes gas fuel delivery pipeline systems, liquid fuel delivery pipeline systems, solid Fuel delivery pipeline system, air delivery pipeline system, multi-phase fuel nozzle 9 and electronic regulation controller 8, said gas fuel delivery pipe...

The invention discloses a multi-fuel system. The multi-fuel system of the present invention can transport gaseous fuel, liquid fuel and solid fuel independently, and is convenient to adjust the delivery flow rate of various fuels independently; in addition, it can also input air to play the role of auxiliary atomization of liquid fuel, and simultaneously with The powdered solid fuel is blended to form a gas-solid mixture, which can effectively improve the delivery efficiency of solid fuel; and, through the electronic adjustment controller, the real-time technical status index parameters of the gas turbine and external control instructions are obtained, and various fuels are calculated accordingly. The delivery volume, and then send fuel volume adjustment instructions to the metering equipment in each delivery pipeline system to ensure that the total fuel volume input into the gas turbine combustor by each fuel delivery pipeline system meets the total energy demand of the gas turbine, and can be used anytime, anywhere. It can switch between different fuels without shutting down for maintenance, and can ensure continuous energy output during the fuel switching process.
Description
technical field [0001] The invention relates to the technical field of gas turbines, in particular to a multi-fuel system. Background technique [0002] The current gas turbines, especially the aeroderivative gas turbines improved from aero-engines, mainly use a single fuel as the medium of use. Temporary stagnation, etc.), the fuel of the gas turbine may require local materials, what is burned; or due to the requirements of some special purposes (such as: a specific emission requirement), it is necessary to require multiple fuels to be produced in a specified ratio combustion. Due to the difference in phase (solid, liquid and gas) and calorific value among various fuels, it is necessary to develop a corresponding fuel supply system for each fuel. If you want to change a certain fuel, you need to replace the entire fuel supply system of the gas turbine, which will increase the maintenance cost and reduce the reliability of the gas turbine. In order to solve this problem, ...
