Description

A kind of coal grill pan burner security risk in-service monitoring control method and device
Technical field
The present invention relates to a kind of coal grill pan burner security risk in-service monitoring control method and device, belong to coal electricity Boiler technology field.
Background technique
The burner of coal electric boiler includes coal pipe and spout, primary air piping and secondary air channel etc..It is set in primary air piping Central air hose introduces shallow bid breeze airflow or mist of oil stream in central air hose or combustion gas is directly entered recirculating zone and catches fire in advance.Burning Device is the key equipment of coal-fired boiler combustion system, and since the operating condition of burner is severe, boiler combustion is simultaneously unstable in addition It is fixed, often there is local overheating.
China has a vast territory, and coal is complicated, and design coal and practical coal are usually not consistent, and burner outlet is easy There is overtemperature and coking, causes the accidents such as burner scaling loss.After burner a large amount of cokings nearby, coke button falls off at dry bottom hopper, Cause dry bottom hopper paulin burnt, production division organizes manpower to carry out coke cleaning work, and risk is larger, and dragveyer is caused when coking is serious And slag runner blocking.
Burner accident has seriously affected the safe and stable operation of boiler.It is badly in need of coal grill pan burner in coal-burning power plant The in-service monitoring and control function of security risk, to ensure that coal unit long period is safely operated.
Summary of the invention
The technical problem to be solved by the present invention is how to realize the in-service monitoring of coal grill pan burner security risk with Control.
In order to solve the above-mentioned technical problem, the technical solution of the present invention is to provide a kind of coal grill pan burner safety winds Dangerous in-service monitoring control method, which comprises the steps of:
Step 1: selecting operating condition according to power plant design data and historical statistical data from all burners and most disliking 1-10 bad burner calculates the accident probability that scaling loss occurs for each burner as research object;Coal electric boiler i-th The probability F of burning damage accident occurs for a burnerPiCalculation formula it is as follows:
In formula, a is the number of units of existing same model coal grill pan burner statistics in database, n0For in database The historical data statistical value of burning damage accident number, n occur for the same model coal grill pan burner havingiFor this TV station coal electric boiler i-th The historical data statistical value of burning damage accident number, t occur for a burneriFor i-th of burner of this TV station coal electric boiler from put into operation to Current calendar hourage, t0The average calendar hourage used for same model coal grill pan burner existing in database Historical data statistical value, KiAnd K0For related coefficient, Ki/K0=at/t0, and Ki+aK0=1;I is positive integer;
Step 2: the temperature of the neighbouring water screen tube of each burner of in-service monitoring;Using boiler water wall temperature sensor, Water screen tube temperature near each burner of in-service monitoring;According to the size of temperature monitoring value, coal grill pan burner scaling loss is defined Accident possibility occurrence P1;According to the duration of temperature monitoring value, defines coal grill pan burner burning damage accident and may occur Property P2, specific criterion and numerical value are indicated in Tables 1 and 2;
Table 1:
Table 2:
Step 3: calculating the mean time to overhaul MTTR of i-th of burneri;Use history number existing in database According in the mean time to overhaul MTTR of i-th of burner generation burning damage accident of line computation coal electric boileri
In formula, τ0Coal grill pan caused by burning damage accident occurs for same model coal grill pan burner existing in database Furnace total unplanned outage time;
Step 4: calculating the dynamic security risk ranking number RPN that burning damage accident occurs for i-th of burner of coal electric boileri:
RPNi=FPi×P1×P2×MTTRi
Step 5: evaluation each burner security risk grade of coal electric boiler;According to coal grill pan burner dynamic security wind The RPN of danger sequence numberiThe security risk of each burner of coal electric boiler is divided into 5 grades, such as table 3 by size;
Table 3:
Step 6: determining the maximum dynamic security risk ranking number in the security risk sequence number of coal grill pan burner RPNmax:
RPNmax=max { RPNi};
Step 7: taking the risk control measure of coal grill pan burner;According to the maximum dynamic of coal grill pan burner Security risk sequence number RPNmaxCalculated value, take following risk control measure:
If 1) RPNmax< 4, there are Pyatyi risk, slight risk, acceptable risk can continue to run;
If 2) 4≤RPNmax< 8, there are level Four risk, ordinary risk, acceptable risk arranges C grades of maintenance (meters within half a year Draw light maintenance) in, it is checked comprehensively;
If 3) 8≤RPNmax< 24, there are tertiary risk, important risk, unacceptable risk arranges interim inspection within this month It repairs, is checked comprehensively;
If 4) 24≤RPNmax< 50, there are second level risk, serious risk, unacceptable risk arranges interim inspection within this week It repairs, is checked comprehensively;
If 5) RPNmax>=50, there is a prime risk, material risk, unacceptable risk, blowing out immediately arranges ad hoc inspection and repair, It is checked comprehensively.
The present invention also provides a kind of coal grill pan burner security risk in-service monitoring control devices, using above-mentioned Coal grill pan burner security risk in-service monitoring control method, it is characterised in that: including boiler water wall temperature sensor, Temperature sensor is connect with boiler protective system in heat power system interface, and the connection of boiler protective system in heat power system interface is fired for coal electric boiler The calculation server in line computation and control of burner security risk, calculation server connect web page server, web page server Connect user terminal browser.
Preferably, the boiler water wall temperature sensor is set on the outside of the water screen tube near boiler-burner.
Preferably, above-mentioned coal grill pan burner safety is run in the computer software that the calculation server uses Risk in-service monitoring control method.
Method provided by the invention overcomes the deficiencies in the prior art, using the method for related coefficient, dynamically considers combustion The probability of malfunction of burner scaling loss realizes online dynamic calculating, in-service monitoring and the control of coal grill pan burner security risk System.If coal grill pan burner dynamic security risk ranking number increases, by reasonably arranging ad hoc inspection and repair or C grades to examine Cultivating makes the security risk of coal grill pan burner be in slave mode, has ensured that coal unit long period is safely operated.
