佛山市精燃机电设备有限公司专注工业燃烧系统配套服务，下面我们就来谈谈熔炼保温炉的燃烧系统。
一、 熔炼保温炉燃烧系统简述
本系统主要由燃气阀组、烧嘴、自动点火装置、火焰监测装置、失火保护装置、燃气检漏装置、伺服机构及鼓风机组系统组成。
本系统在运行过程中，阀门检漏、炉膛吹扫、燃气点火、负荷调节、熄火可自动控制，燃气超欠压、助燃风欠压、失火可自动保护。
本系统是根据熔炼炉负荷、炉膛结构、炉内压力、炉内温度、燃气发热值、压力、密度、温度、华白数等多项参数而设计的。所以，针对性强、适用该炉型锅炉。
二、熔炼保温炉燃烧系统主要功能
1、能量转换：燃气喷出后在燃烧筒内与助燃空气二次混合后被自动点火后与空气三次燃烧。产生的高温火焰从烧嘴高速喷出，加强炉内燃烧气体循环，提高炉内温度均匀性。
2、失火保护：在突发事件或停电时具有自动熄火保护功能。自动熄火保护是指：机组在正常运行过程中突发性熄火(忽然没有气源、断电等造成的熄火)，这时高灵敏度的火焰监测器就会给程控器一个报警信号，机组会全部自动停机
3、煤气压力低或压力高保护：机组能在煤气供应压力低于下限值或超过上限值时自动关闭，以保证系统安全。
4、供风压力低保护：能在供风压力低于设定值时自动关闭机组。 主燃气阀组双回路保护：降低燃气阀组泄漏率，炉膛自动吹扫。
5、具有与主设备运行联锁保护功能。 自动点火、火焰检测联锁保护。
6、 燃烧热负荷可随熔炼炉的负荷变化而进行自动调节，当负荷增大时可自动加大进风量和进燃气量，当负荷减小时可自动减小进风量和进燃气量。当温度超过设定值时具有自动关闭大火保持火种的待机功能，当温度下降到设定值时具有自动开启功能，避免了频繁停炉。
7、 该系统在灰尘、水等杂质存在的情况下仍正常使用

产品英文详情介绍
foshan electrical and mechanical equipment co., ltd. focuses fine fuel combustion systems for industry support services, here we come to talk about the melting holding furnace combustion system. a, melting holding furnace combustion system description the system consists of a gas valve, a burner, automatic ignition device, flame monitoring apparatus, fire protection devices, gas leak detection device, the servo mechanism and the blower group system. during operation of the system, valve seal, furnace purge gas ignition, the load adjustment, can turn off the automatic control, over-voltage gas, combustion air undervoltage, automatic fire protection. this system is based on a number of parameters of the furnace load, the structure of the furnace, the furnace pressure and furnace temperature, calorific value gas, pressure, density, temperature, etc. wobbe number and design. therefore, we targeted for the furnace boiler. second, the main function of melting holding furnace combustion system 1, the energy conversion: automatically discharged after ignition combustion gas and air is combusted in the cylinder three times with the secondary combustion air mixture. high temperature flame generated by high velocity from a burner, the combustion gas circulating furnace to strengthen, improve the uniformity of temperature in the furnace. 2, fire protection: protection with automatic turn off when power failure or emergency. automatic flame protection means: unit sudden flameout during normal operation (no sudden gas source, a power failure caused by flame), then the high sensitivity of the flame detectors will alarm signal to a programmer, all units will automatic stop 3, a low pressure gas or high pressure protection: the unit can be automatically closed when less than the lower limit or exceeds the upper limit value of the pressure gas supply to ensure system security. 4, the low pressure air supply protection: the unit will automatically close when the air supply pressure is below the set value. dual circuit protection valve main gas: a gas valve to reduce the leakage rate, the furnace was purged automatically. 5, the master device has run interlock protection. automatic ignition, flame detection interlock protection. 6, the thermal load combustion can be carried out with the smelting furnace load changes automatically adjusted when the load is increased to increase the intake air flow automatically into the gas volume and, when the load is reduced automatically reduces the amount of wind and the quantity of gas feed. when the temperature has exceeded the set value automatically close fire held fire standby function, with automatic opening function when the temperature drops to the set value, to avoid the frequent shutdown. 7, the normal use of the system is still melting holding furnace combustion system in the presence of dust, water and other impurities, choose foshan fine electrical equipment co. burning.
