How should Li Yalu burner control ability safety?

Burner of Li Yalu burning gas accords with policy of our country industry, market prospect is very good, have development outlook greatly. It is however in design of development of burner of Li Yalu burning gas, character burning gas, explode combustibly, easily reach noxiousness, bring the first issue that fully control makes.

The security that manufacturer of burner of methanol profit elegant way introduces to light burner of gas profit elegant way for everybody controls a demand: Enrage the combustion character inside the chamber of a stove or furnace according to lighting, content of requirement of safe to its control basically has beforehand the protection that monitoring of condition of hair drier, automatic ignition, combustion, dot does not catch fire, protection of flameout, light baric force discretion to be restricted pressure of protection, air is not worth protection, cut off the power.

One, before airing Li Yalu burner is igniting beforehand, must have period of time air beforehand, blow the more than air in the chamber of a stove or furnace and flue divide or attenuant. Because inevitable ground is superabundant inside the chamber of a stove or furnace of combustion engine work,stay burn gas, if did not undertake air beforehand and igniting, have the risk that produces explosion. Must blow more than air be divided clean or attenuant, make sure chroma burning gas is not inside explosion limit. Air time and structure of the chamber of a stove or furnace and blowy quantity concern general setting to be 15-60 second beforehand.

2, automatic ignition lights gas combustion guildelines to use electric spark ignition, facilitating implementation automata. Usable high pressure ignites transformer produces electric arc to ignite, ask its output energy to be: 15mA of ≥ of voltage ≥ 3.5K V, electric current, ignite time is commonly: 5 seconds of 2 ～ .

3, when the protective combustion machine that the dot does not catch fire ignites, connect burn gas, light gas to catch fire combustion. Ignition movement asks to happen before lighting gas to be connected, form ignition temperature field first, facilitate catch fire combustion. If the dot does not catch fire, detector feeling does not measure blaze blaze signal, combustion machine enters protective state. Want to the time that enters protective state from ignition proper, both neither can be too short also cannot grow too. If pass short, have not enough time to form stable blaze; to grow too, the chamber of a stove or furnace is entered when a large number of lighting is being caused to enrage when the dot does not catch fire. General requirement is connecting second of 2-3 burning gas, the blaze signal that to blaze detector feeling measures has combustion opportunity judgement, did not catch fire to enter protective state, catch fire to maintain combustion.

4, condition of combustion of combustion condition monitoring must give dynamic monitoring, once blaze detector feels,measure flameout signal, must feedback inside extremely short time combustion machine, combustion machine immediately protects position into the person, cut off supply burning gas at the same time. Blaze detector wants can normal feeling to measure blaze signal, both neither wants sensitive, not slow also. Because sensitive, if combustion condition has misoperation of fluctuant easy generation and slow, lag of feedback blaze signal, go against safety to move. General requirement answers time not to exceed 0.2 seconds from what flameout issues flameout signal to blaze detector.

5, machine of flameout protection combustion is in combustion process, be like accident flameout, combustion machine enters protective state. Because the chamber of a stove or furnace is blazing. Light gas to enter easy happening to deflagrate, reason must enter protective state inside extremely short time, cut off supply burning gas. From produce flameout to combustion machine to protect position into the person, of this process answer time to ask not to exceed 1 second.

6, discretion of pressure burning gas is restricted to protect machine of combustion burning gas to stabilize combustion to have certain limits, allow to light baric force to fluctuate inside certain limits only. Demarcate lights the end that enrages high low pressure is to ensure blaze stability: Do not take off fire, not flameout also not temper, the output that decides combustion machine with time limit heats up power, make sure equipment safety economy moves. Exceed this range when pressure burning gas, should lock up calm combustion mechanic to make. Combustion machine design uses feeling of aeriform pressure switch to measure pressure signal commonly, output switch to measure signal, in order to controls the corresponding job of combustion machine.

Manufacturer of burner of methanol profit elegant way represents, solve problem of the leak inside furnace to have 3 ways: It is to strengthen air time and hair drier are measured beforehand, blow divide or gas; is lighted inside attenuant furnace 2 it is to light tracheal road to use structure of series connection of 2 electromagnetism a powerful person, raise systematic security; 3 it is to use pipeline leak to detect device, undertake detecting to lighting gas pipeline before ignition, if light gas leak,achieve certain amount to lock up calm combustion mechanic to make namely.
