1、提供小于:能耗:重油消耗-180 千克/吨固体产品,(池壁是否可以使用高铝砖) ,可以用,但寿命短,维修次数多,不太合算。 (窑炉外围尺寸)王工提供给你。太阳最红 17:43:04(蓄热室工作原理:王工从窑炉书籍上摘入以下即可, ,结合后面工作次序,天然气改为重油) ,蓄热室为西门子式蓄热装置,工作原理:Energy consumption,It will take 180KG Heavy oil to produce one ton solid product.We usually use the fused zirconium corundum bricks for the side wa

2、ll of melting end. We can also use the high Alumina bricks for the side wall as you required but the furnace has a much shorter lifespan, much more repair compared with the fused zirconium corundum bricks.太阳最红 17:43:42蓄热室工作原理:蓄热室是将烟气的热量通过格子砖的蓄热作用,传给空气。当高温烟气流经蓄热室格子砖表面时,将热能传递给格子砖,此时砖的温度逐渐升高。当换成空气流过该格子

3、砖表面时,蓄积在砖内的热量则传给空气,从而达到预热空气的目的。对于中间传热介质格子砖来说,一个周期是它的加热周期,另一个周期是它的冷却周期,如此周而复始地反复进行。蓄热室中气体流动的方向不是连续不变,而是周期性的改变,所以说蓄热室是周期性工作的换热设备。关闭烟道翻板(1)烟道翻板(2)自动开启,助燃空气通过烟道翻板(1)里面进风口进入蓄热室(1)进行热能交换,延时后,电磁阀(1)打开,同时电磁阀(2 )关闭,二次空气进入小炉空气通道(1)通过喷火口喷入池窑内,与重油混合燃烧,喷枪(1)投入使用,同时喷枪(2)关闭。烟气经过喷枪(2)上方的小炉通道进入蓄热室(2)从上往下将格子砖加热,再从水平烟

4、道(2)排出,汇入总烟道经烟筒排出废气。反之,关闭烟道翻板(2)烟道翻板(1)自动开启。助燃空气通过烟道翻板(2)里面的进风口进入蓄热室(2)进行热能交换,延时后,电磁阀(2)投入使用,同时电磁阀(1)关闭,二次空气进入入小炉空气通道(2)通过喷火口喷入池窑内,与重油混合燃烧,喷枪(2)投入使用,同时喷枪(1)关闭,烟气经过喷枪(2)上方的小炉通道进入蓄热室(1)从上往下将格子砖加热,再从水平烟道(1)排出汇入总烟道经烟筒排出废气。整个工作过程如此循环进行,每 2535 分钟循环一次。所有原理实行连锁延时控制,即关闭喷枪与开启另一支喷枪不同时进行,关闭烟道翻板与开启另一个烟道翻板同时进行,实行

5、自动延时交换。 (加入了时间延时装置以后节约了能源,同时烟囱不冒黑烟达到环保要求)。The working principle of regeneratorThe checker inside the regenerator has the function of regenerate the heat energy, it can transfer the heat energy to the air. The heat energy could be transferred to the checker when the high-temperature smoke goes throug

6、h the checker, then the temperature of checker bricks increasingly。When the cold air goes though the checker bricks ,the heat energy inside the checker bricks will heat up the air to make them become combustion air to assist fuel burning. For the checker bricks, there are two cycles, one is heating

7、cycle and another one is cooling cycle., the two cycles repeat continuously. The air direction is changing periodic, so we can take the regenerator as a kind of periodic heat exchanger.The working progress of regenerator as below,Take the two regenerators as an example.No.(1) Flue Turning Board Clos

8、e and No.(2) Flue Turning Board will automatically be opened, the combustion-supporting air will come into No.(1)Regenerator for thermal exchange through No.(1) Flue Turning Board, after time delaying, the No.(1) solenoid Valve will be opened, meantime, the No.(2) solenoid Valve will be closed, the

9、secondary air come into No.(1) port air channel and then get into the flame space mixing with the heavy oil to burn together. At this time, the No.(1) burner start to burn, and No.(2) burner will be closed automatically. The smoke will get into No.(2) regenerator through the port channel above No.(2

10、) burner to heat the checker from top to the bottom, then expelled from No.(2) Horizontal Flue ,and afflux into the chief flue to expel the exhaust smoke from the main chimney in the end. Contrarily, close No.(2) Flue Turning Board and No.(1) will automatically open ,combustion supporting air will c

11、ome into No.(2) regenerator for thermal exchange through No.(2) Flue Turning Board, after time delaying, the No.(2) solenoid Valve start to work, meanwhile No.(1) solenoid valve close, and secondary air come into No.(2) Pre-burning Room to mixing with the heavy oil to burn, then the No.(2) burner st

12、art to operate, and No.(1) burner will be closed at the same time. The smoke will come into No.(1) regenerator through the channel above No.(2) burner to heat the checker brick from the top to the bottom, then expelled from No.(1) Horizontal Flue ,and afflux into the chief flue to expel the exhaust

13、gas from the chimney in the end. All the above mentioned operating system would circulate 25 to 35 minutes each time. All the operating principle are used Catenation Time Delay Control, that is, one burner will not be closed at the same time when opening another burner. This system use automatic Time Delay Exchange (The Time Delay Facility can save resource and meet the environmental protection requirements).
