Through changing nozzle flame detector monitoring range, extend to front end in the control nozzle flame by the control nozzle flame tail end of original design, even it is low during to 750kcalNm3 to 6kPa or calorific value when the pressure that uses the gas, though within the change of nozzle flame was in the monitoring range of nozzle flame detector all the time, the nozzle can not stall yet, can keep the safe operation.
Description
Technical field
The utility model relates to field, annular lime kiln combustion chamber, is specifically related to a kind of burner nozzle of annular sleeve kiln flame detector mounting structure.
Background technology
Annular lime kiln has been widely used in the industry production such as metallurgy, chemical industry fat lime, particularly metallurgy industry at home and has mainly used the fuel gas with low heat value such as coal gas of converter, mixed gas (coal gas of converter multifuel combustion blast furnace gas, blast furnace gas multifuel combustion natural gas) as fuel.Technological design General Requirements gaseous-pressure 16 ~ 23kPa, calorific value 1400 ~ 1800kcal/Nm
3.Gas burning system safety interlocking, combustion gas supervisor is provided with the high and low warning of gaseous-pressure and quick cutting device, all automatically can cut off combustion gas when gaseous-pressure is on the low side or higher.Each burner is monitored flame continuously with a special flame detector, and when flame detector monitoring is less than flame, burner will be died flame-out automatically, and sends information to PLC.
Current domestic metallurgy industry gas burning system generally has features such as being interrupted recovery, continuously transmission & distribution, be incorporated into the power networks, the change of each converter, blast furnace process rhythm easily causes the change of combustion gas yield, cause surplus or the deficiency of gas burning system generation area property or discontinuity, thus affect the stable transmission & distribution of gas burning system.Therefore, often there is low pressure low thermal value phenomenon in the combustion gas extremely unstable of the actual use of annular lime kiln.In production practices, as gaseous-pressure < 12kPa or calorific value < 1400kcal/Nm
3time, burner automatically will be died because combustion flame change departs from flame detector monitoring range and be caused frequent stopping working, and has a strong impact on the seed output and quality of lime, even jeopardizes kiln security of operation.
For fuel gas with low heat value particularly blast furnace gas (mean calorie 750kcal/Nm
3) use on annular lime kiln, domesticly propose gas-preheating technology, the efficient thermal technology such as spraying technique, flameless combustion technology technology.The disclosed annular lime kiln device for utilizing residual heat of waste gas of Chinese utility model patent (application number 200820031027.7, applying date 2008.01.23) is by setting up flue gas-gas change heater, uses the waste gas heating low temperature combustion gas of sleeve kiln." application of flameless combustion technology in annular lime kiln " (article numbering 1673-7792 (2012) 06-0010-03, author Chen little Juan, Jiang Jirui) a kind ofly can improve kiln calcining heat by simulation research and development, ensure flame stabilization, improve thermo parameters method and avoid the formation of the flameless combustion technology in district of localized hyperthermia, make the use of fuel gas with low heat value on sleeve kiln accomplished.But abovementioned technology still comes with some shortcomings, one is that correlation technique is still in the exploratory stage, and practical application example is few; Two is that transformation input cost is high; Three be Low Pressure Gas Network power low heat value fluctuation time burner still easily stop working.
Summary of the invention
The purpose of this utility model is exactly the deficiency for above-mentioned technology, provides a kind of and uses low-pressure, burner nozzle of annular sleeve kiln flame detector mounting structure that fuel gas with low heat value does not stop working.
For achieving the above object, burner nozzle of annular sleeve kiln flame detector mounting structure designed by the utility model, comprise burner panel and be arranged on the burner panel brick in described burner panel, described burner panel offers the monitoring hole for installing burner flame detector, described burner panel brick has the first through hole be connected with combustion chamber with described monitoring hole respectively, described monitoring hole and described first through hole are identical with the angle of axis, burner hole respectively and be 15 ° ~ 40 °.
Further, described first through hole is horn-like hole.
Further, described burner panel also offering the peep hole for observing burner flame, described burner panel brick having the second through hole be connected with combustion chamber with described peep hole respectively.
Further, described peep hole and described second through hole are 20 ° ~ 35 ° with the angle of axis, described burner hole respectively.
Compared with prior art, the utility model has the following advantages: by changing burner flame detector monitors scope, front end in monitoring burner flame is extended to, even if the pressure of working as use combustion gas is low to moderate 6kPa or calorific value is low to moderate 750kcal/Nm by intrinsic monitoring burner flame tail end
3time, although burner flame change is within the monitoring range of burner flame detector all the time, burner also can not stop working, and can keep safe operation.
