Horizontal Industrial Diesel Gas Steam Boiler
Fangkuai Boiler has carried out a large-scale welding revolution, eliminating traditional manual welding operations with low efficiency, low accuracy and poor stability, and converted it to the use of mechanical welding equipment with high efficiency, high accuracy and high stability for automatic operation . Realize welding automation of all important parts from the drum to the tube sheet. The submerged arc welding, argon arc welding, carbon dioxide welding and other welding details of the process have also made corresponding intelligent changes, workers' welding environment is cleaner, and the quality of boiler welds is more guaranteed.
Electric boiler supplying domestic matters need to pay attention what? 1, electric boiler carefully check each system before opening oven parts electric boiler, focused on checking the three security controls pressure gauge, safety valve, gas pipe fittings, water level is normal, everything is correct, put on compliance clothing to continue to work. Electric horizontal industrial diesel steam boiler 2, please do one-handed operation when the water in the electric boiler, water regulatory action is single-handedly opened the door in one hand and a water injector steam valve, when the water column to a predetermined level, the first valving (valving time face not being on the water, to prevent splash injuries face) and then turn off the water gate, electric boilers provide domestic water to be alert order can not be reversed. When electric boiler work, surrounding someone must guard the moment the water level and pressure gauges, there can be no neglect of duty, to adjust work schedules when working at night, night shift work, be sure to have a good rest during the day, not at night when this work I would doze off, because if there is any carelessness, accidents will happen. Points to note what? 4, electric boilers night to the boiler daily sewage treatment, water table should clean up once every night. For motor and other mechanical equipment have always been its inspection, if any abnormal findings, the investigation must be immediate. Weekly safety valve should be checked whether it is safe.
How staged combustion boilers and boiler manufacturers to understand the relationship between the boiler and gas consumption of the equipment, from the current point of view, it is a wide range of applications and there are many types, and also one of the main keywords of the website in important product, so there is necessary to conduct a comprehensive knowledge and understanding, so as to know how to correctly and reasonable use of the product, and at the same time, there is a good use of effects in the use of the product. 1. How can the afterburner boiler to understand? Afterburning boiler is understood, one can be understood as a waste heat boiler, waste heat boiler because the band is divided into afterburner means and without afterburner means two; two is considered to be carried out at temperatures not meet the needs of a supplementary device, to supplement the heat to meet the temperature requirement. So, specifically how to understand, but also the actual situation, to decide it. 2. Are there different boilers burning different method? Boiler, which there are many types, such as coal-fired boiler, gas boiler, boiler methanol, the electric boiler, and different kinds which are different corresponding to different media, and firing method. So, we can draw the conclusion that the answer to this question is yes. And even the same kind of boiler, if it is different manufacturers, then, will have different firing methods, so that the boiler burning method, which is also associated with two boiler types and manufacturers. 3. Check before use horizontal industrial diesel steam boilers Is it important? Steam boiler inspection before use, from a professional point of view, this is an important work, and can not be sloppy treat, but also need to know the specific content of the work. Its work on the content is as follows: the internal parts of the boiler inspection, such as pipes, pressure gauges and water level tables, etc. These, are intact and can be used normally. Also check to see if the water used in the boiler through a softening process is clean and clean, can not contain impurities, dirt and grease. 4. different boiler manufacturers, boiler air consumption the same? Boilers different manufacturers, then, boiler air consumption is not the same, but can not be exactly the same, but the difference is not great. On the considerations to take into account air source heat this one. Generally, the heat value of natural gas is 35 MJ / m, and the boiler gas consumption per ton of 70-80 m3 can be estimated, so that air consumption of the boiler is half a ton of 35-40 m3 / hr .
The main structure of the internal combustion boiler detail: In the combustion boiler is a main flue of all, combustion residue after combustion of the fuel without directly heating the surface of the mixed working fluid is heated and the flue gas, together with steam as the working fluid work output of method of operation, high efficiency boilers. The internal combustion boiler thermal industry is part of the production of steam. Next to be described in detail the structure of the main combustion boiler: a boiler shell, the pressure receiving member is an important potshell shell type boiler, it is the role space for storing water and soda and steam are separated place. In shell type boiler, boiler shell placed combustion chamber (furnace) and the heating surface, the effect of which was underway boiler body. Potshell cylindrical container is made of welded steel sheet, we split it into three parts: the cylindrical portion is an intermediate portion, both ends of the tubesheet portion is simplified, and some people open end of the tube sheet hole. Simplified by the two or more tube sections butt weld made, the minimum length of the barrel section is not less than 300mm. When the boiler is greater than the inner diameter of the shell boiler 1000mm. Simplified access potshell wall thickness should be not less than 6mm, inner diameter of the shell when the pot is not more than 1000mm, simplified access to the boiler shell thickness is not less than 4mm. Both sides of the drum and the tube plate is connected to the boiler shell simplified, many small holes drilled in the tube plate, through the hole in the fire tube. Front tube plate further defines a larger hole furnace connected. There are many simple pan upper takeover, which takes over a main steam valve, safety valve, manometer, water gauge and the like. Pan with water separator housing interior, surface sewage, and the like into the water. 2, furnace, furnace boilers are specific shell type pressure element, inside a furnace combustion chamber, the outer coating from the boiler water. Furnace outside the furnace by the water pressure. Therefore, it is the worst working conditions the pressure element shell type boiler. Because the furnace by the high temperature flame burning, the temperature is higher than the temperature of the boiler shell, its thermal expansion problems particularly prominent in the boiler fuel, the oil combustion temperature is high, a high furnace thermal strength, severe temperature changes, there is required furnace good performance thermal expansion and contraction. General furnace are made waveform. And some shell type boiler or furnace to a flat circular flat circular shape Singapore. 3, fire tube, the main fire tube boiler heating surface of the boiler shell. Generally use is made of boiler steel φ51mm ~ φ102mm, the front and rear tube plate by welding or play mode coupled expanded joint, when Expansion, connecting the fire tube and inflation port after inflation tube plate using 90 ° pull side contact. Front and smoke at a relatively low temperature plate, inflation bell mouth pull side can be connected. When a welded connection, in order to ensure sufficient bonding strength, and the tube end is not overheating, the tube end projecting required length of the tube plate is not less than the wall thickness plus 1.5mm, but not in excess of the connecting seam 5mm. Imported oil-fired boiler, and some in the furnace exit, fire tube to tube sheet welding connection. But in other parts of the fire tube to tube plate with flange 90 connected to the expander. Effect is produced outside the smoke tube of the tube furnace heated by flue gas through the combustion water in the tube, in order to gradually generate steam, also called "squib." Generally have the following forms: a straight barrel, also called "light pipe", the advantage of a small light pipe smoke resistance, the disadvantage is fouling the inner pipe easily. Heat transfer effect is also poor. Light pipes are typically seamless steel tube, but also useful for welding boiler tube inlet. Another is a threaded tube, which is pressed inwardly out of a recess in the seamless pipe, it seems like a thread, so called "threaded pipe." The advantage is that the flue gas flow within the tube, changing the flow cross-sectional area, the flow velocity of flue gas is also changed and swirl effect. Therefore, it is better than the light of the heat transfer tube and hard fouling. The disadvantage is greater than the resistance through the light pipe has a certain velocity before the flue gas swirl effect more obvious. The third is to add steel wire or steel wire to the formula Fu light tube. It is a light pipe inside the tube into a tube-type inflammation oxidation resistance good steel wire, inside the flue gas flow at the fire tube, steel wire plays a role similar to the threaded tube. If you want to fire tube cleaning, can easily be removed steel wire, steel wire and light pipe are more convenient cleaning. This form of fire tube easy to manufacture, simple maintenance. In order to maintain the strength of the tube plate, according to strength calculation, be reinforced hole in a predetermined position region of the tube plate. Specific fire wall is thickened, with a thick-walled welded tube to tube plate, so that both as reinforcement, acting also as heating surface, the thick-walled tubes referred to as "bracing tube."
