Problems solved by technology

[0014] As described above, since the burner 20 is manually controlled in consideration of the customer's load change according to the conventional steam power plant, erroneous operation or misoperation occurs during a rapid load change due to a real-time accident of power equipment, and therefore, in Accidents frequently occur during ignition and extinguishment of generators, because the process of ignition and extinguishment of burners is complex and sensitive
In addition, a skilled supervisor must concentrate on controlling the burner 20, so when the supervisor's attention is not concentrated, a control error occurs

Embodiment Construction

[0027] Referring to the accompanying drawings, namely FIGS. 4 to 9 , the burner can be described in detail based on the characteristic data that affects the ignition and extinguishment of the generator burner (such as the relationship between the output power of the generator and the number of burners that are ignited and extinguished). The relationship between the header pressure and the number of burners ignited and extinguished, and the operation of the burners when driving the generator and stopping the generator) Automatic burner control system that automatically and correctly controls a group of burners and Preferred embodiment of its method.

[0028] Fig. 4 is a block diagram showing a steam power plant.

[0029] As shown in FIG. 4 , the steam power station includes: a combustion furnace 10, which is heated by a plurality of burners BNR1 to BNR20; a boiler 30, which uses the combustion furnace 10 to heat water to generate steam; a steam turbine 40, which uses the steam ...

Abstract

The present invention provides an automatic combustor control system for steam-power station. Said automatic combustor control system includes; valve controller for measuring and controlling manifold pressure of combustor; power quantity supply device for measuring and supplying power quantity produced by power generator,; central control table for setting and providing reference data for controlling ignition and extinction of combustor and monitoring error status of combustor; and processor for making the reference data provided by central control table be compared with at least one of data inputted by valve controller for measuring local manifold pressure or supplied by power quantity supply device, and for automatically controlling ignition and extinction of combustor.

Description

technical field [0001] The present invention relates to multiple burners for steam power plants, and more particularly to a system for automatically controlling the multiple burners. Background technique [0002] Typically, the rotational speed of the steam turbine determines the amount of power produced by the steam power plant. The amount of steam provided by the boiler determines the speed of the turbine. The steam volume of the boiler is determined by the number of burners used to heat the furnace and the header pressure of this burner, that is, by the amount of fuel sent to the burner . Therefore, skilled managers of steam power plants control the number of burners to be ignited and the amount of fuel added according to the customer's load changes. [0003] The operation of the burner for controlling the amount of power generated by the generator will be described below with reference to FIGS. 1 and 2 . [0004] FIG. 1 is a graph showing the relationship between the...
