Summary of the invention
The purpose of this utility model be exactly for effectively solve the gas of burner in using mix uneven, combustion efficiency is poor, artificially regulate problem such as flame, and a kind of intelligent multi-class workload pre-mixing type combustion apapratus with advantages such as low emission, high operational efficiency, energy-saving and emission-reduction is provided.
For achieving the above object, the utility model adopts following technical scheme:
A kind of intelligent multi-class workload pre-mixing type combustion apapratus, it comprises burner head, gas mixing device, igniter, flame detecting device, full-automatic blower fan and automatic control module composition.Its burner head is characterised in that the top end face burning zone adopts metallic fiber, and internal layer is the metal stratum reticulare, and the below is the metal uniform gas board.The mixed gas passage that gas mixing device is made up of the vertical airduct of the center Gas Pipe and the outside is welded with the spiral stream guidance blade on the Gas Pipe, laterally airduct directly connects full-automatic how fast air blower.The air that burning needs is to enter vertical airduct by how fast blower fan through horizontal airduct, is forming swirling eddy immediately in vertical airduct, and is mixed with the combustion gas that sprays into through the gas nozzle level.Gas flow is to regulate by the combustion gas ratio adjusting valve of installing on the Gas Pipe, and how fast blower fan is that described multispeed electric machine is the motor with cup rotor of tapped 2-5 speed.The electric current that automatic control module is controlled the speed of how fast blower fan and combustion gas ratio adjusting valve is respectively realized the adjusting of loading, and has functions such as autompulse igniting and ionic flame detection.
The described even device of air of burner of the utility model design comprises metal stratum reticulare, the metal uniform gas board of top end face burning zone and its underpart; Metal stratum reticulare and metal uniform gas board outer end and the welding of burner head top.Pulse firing pin and ionic flame detection pin are installed on the top end face burning zone, are realized that by automatic control module igniting automatically and flame detect.
The described spiral stream guidance blade of burner of the utility model design is welded on the Gas Pipe in the mixed gas passage that Gas Pipe and vertical airduct are formed, and air produces rotation through the spiral stream guidance blade, and combustion gas is injected the air swirl from nozzle.Be distributed to the metallic fiber burning zone through even device of air after air fuel gas mixes strongly in eddy flow, form flameless combustion immediately.So just guaranteed that combustion gas-air can fully mix, thereby reached burning evenly and the purpose of completing combustion has improved the thermal efficiency, reduced the discharging of pollutant.
The described automatic control module of burner of the utility model design is made up of circuit board, control panel and circuit, can realize electronic ignition, the control system that flame detects and load is selected.
The burner of the utility model design is determined the air fuel gas mixed proportion by automatic control module by the combustion gas ratio adjusting valve when regulating load, finish proportion control to air fuel gas, change the inching switch that in control circuit board, has increased gas quantity according to thermic load simultaneously, and be easy to realize fully premixed and conversion atmospheric burning type, strengthened the flexibility on reality is used.So the burner of the utility model design can guarantee that air fuel gas can mix preferably under different load, can guarantee the accuracy of the ratio of gas-air when Load Regulation, thereby realized regulating completing combustion under the ratio at different load.
The beneficial effects of the utility model are: burner adopts metallic fiber infrared combustion technology, the anti-thermal shock good stability, and mechanical shock resistance is strong, and combustion noise is less, and thermal inertia is little; Adopt control complete pre-mixing type burning automatically, combustion intensity is big, and load regulation rate is big, the efficiency of combustion height, and CO, NOx discharging is low, and flameholding is difficult for tempering; Adopt hot surface ignitor, guaranteed the reliability of burning; Owing to reduced the airduct resistance, can adopt lower-powered blower fan, thereby reduce noise, saved electric energy.
