Problems solved by technology

However, when the current power plant simulator is used to simulate the combustion process of the furnace, when the amount of fuel in each layer is adjusted, the influence on the flame center cannot be correctly reflected, and the response to changes in steam temperature and pressure is not obvious, so it cannot be accurate. Effective adjustment of the furnace combustion process

Abstract

The invention discloses a furnace combustion adjustment method, comprising: establishing a furnace combustion model; wherein the interface points of the furnace combustion model include six layers of wind and fuel points, and the six layers of wind and fuel points are distributed in the furnace from bottom to top Middle: Simulate the combustion process of the furnace according to the combustion model of the furnace, and obtain the central position of the flame; adjust the combustion process of the furnace according to the obtained central position of the flame. In addition, a furnace combustion adjustment system is also disclosed. In the furnace combustion adjustment method of the present invention, the furnace combustion model established adopts six layers of wind and fuel points, and by correcting the influence of the fuel and air volume of each layer on the geometric characteristics of the furnace, it can well reflect the influence of different layers of fuel and wind on the center position of the furnace flame, Then the combustion process of the furnace can be adjusted accurately and effectively.

Description

technical field [0001] The invention relates to the technical field of furnace combustion, in particular to a furnace combustion adjustment method and a furnace combustion adjustment system. Background technique [0002] Controlling the combustion process in the furnace to keep it stable and meet preset specifications is critical for power plants. With the help of the power plant simulator, you can become familiar with the logic of the field configuration, the operation mode of the equipment, and enhance the ability to deal with the accident. The furnace combustion system is a very important part of the simulator, and it is the hub connecting the wind system, flue gas system, fuel system and steam system. Whether the simulator can truly reflect the situation on site is very important to the whole simulator, which directly affects the adjustment and control effect of the furnace combustion process. However, when the current power plant simulator is used to simulate the comb...
