Abstract
The utility model discloses a coal burner is many, and monitored control system is examined to fire, examine probe, main fuel trip system and controller including boiler, coal burner, a plurality of fire, wherein: coal burner sets up in the boiler, and the fire being examined the probe and setting up in coal burner top, and the fire is examined the probe and is arranged in proper order side by side, makes its test range corresponding with the excursion of ignition point position, and the equal connection director of probe is examined to every fire, and the main fuel trip system is connected to the controller, and when all fire were examined the probe and are not all detected out the ignition point, controller control main fuel trip system tripped. The utility model discloses a many fire are examined the detection and can be improved the fire and examine the signal accuracy, improve the boiler operation security.
Description
Technical field
The utility model relates to the many flame-detected control system of a kind of coal burner.
Background technology
In coal-fired power station boiler, the normal case of fire using fire monitor equipment to judge coal burner.The probe examining signal for detecting fire is one, and be installed on fixed position, detecting easy ignition point, there is a problem in this fire defector mode: when ature of coal changes or combustion parameter changes, and variation obviously can occur in the position of ignition point, and the detection position of flame detecting probe is fixing, the accuracy of at this moment fire inspection signal can obviously reduce, and " will have fire " sometimes and be judged as " without fire ", and trigger boiler main fuel trip action, make troubles to production, threaten unit safety operation.
Utility model content
The utility model is in order to solve the problem, and propose the many flame-detected control system of a kind of coal burner, native system detects the case of fire of different distance scope respectively by multiple flame detecting probe, effectively can improve the accuracy of fire inspection detection.
To achieve these goals, the utility model adopts following technical scheme:
The many flame-detected control system of a kind of coal burner, comprise boiler, coal burner, multiple flame detecting probe, main fuel trip system and controller, wherein: coal burner is arranged in boiler, flame detecting probe is arranged at above coal burner, flame detecting probe is arranged in order side by side, make its investigative range corresponding with the excursion of ignition point position, the equal connection control device of each flame detecting probe, controller connects main fuel trip system, when all flame detecting probes are not all tested with ignition point, controller controls main fuel trip system trip.
The excursion of described ignition point position changes according to ature of coal or combustion parameter change is carried out experiment and obtained.
Described flame detecting probe number is 2-5.
The setting position of described coal burner and the position level of ignition point, ensure that the unburned coal dust jet of coal burner injection is through ignition point Thorough combustion.
The adjustable angle of described flame detecting probe.
Distance between described flame detecting probe is adjustable.
The beneficial effects of the utility model are:
(1) adopt many fire inspection detections can improve fire inspection signal accuracy, improve boiler operatiopn security;
(2) detection event of all flame detecting probes of controller monitoring, and control main fuel trip system, in time according to the detection case of ignition point, carry out emergent management.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein, 1, flame detecting probe, 2, coal burner, 3, ignition point, 4, unburned coal dust jet, 5, the coal dust jet of burning, the proximal most position that A, ignition point are possible, the highest distance position that B, ignition point are possible.
Detailed description of the invention:
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
As shown in Figure 1, the many flame-detected control system of a kind of coal burner, comprise boiler, coal burner 2, multiple flame detecting probe 1, main fuel trip system and controller, wherein: coal burner 2 is arranged in boiler, flame detecting probe 1 is arranged at above coal burner 2, flame detecting probe 1 is arranged in order side by side, make its investigative range corresponding with the excursion of ignition point position, each flame detecting probe 1 is connection control device all, controller connects main fuel trip system, when all flame detecting probes 1 are not all tested with ignition point, controller controls main fuel trip system trip.
The excursion of ignition point position changes according to ature of coal or combustion parameter change is carried out experiment and obtained.As shown in Figure 1, A is the possible proximal most position of ignition point, and B is the possible highest distance position of ignition point, and arrangement and the detection range of so all flame detecting probes 1 all set according to the distance between AB.
Preferably, flame detecting probe number is 3.
The setting position of coal burner 2 and the position level of ignition point 3, ensure that the unburned coal dust jet 4 of coal burner injection is through ignition point Thorough combustion.
Flame detecting probe is fixed in boiler by support, and support angle is adjustable, makes the adjustable angle of flame detecting probe.
Distance between flame detecting probe changes according to the possible position of ignition point 3.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the restriction not to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendment or distortion that creative work can make still within protection domain of the present utility model.
