Maintenance of oil-fired boiler! What oil-fired boiler include? Fuel oil-fired boiler comprising a boiler water, hot water boiler fuel, the fuel heating boiler, oil bath boiler, and two sets of steam boiler for fuel, gas oil refers to the boiler fuel (such as diesel, kerosene), heavy oil, residual oil or crude oil fired boilers. Maintenance of oil-fired boilers? After conducting oil furnace shut until the furnace cooled water to the boiler water below 70 ℃ exhausted, the internal completely remove the dirt, washed away, all manholes, hand holes, valves and other pipeline tight blockade, and with a blind plate and running boiler completely isolated. After all of the alkaline solution is added, and then injected into the soft water boiler, until the water coming out from the highest point till the boiler, the water supply valve is closed, note that the average mixing an alkaline solution inside the boiler.
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."
Our emphasis on increasing green, local governments also boiler operation produces nitrogen oxides and smoke emission requirements become more stringent. Fast boiler followed by the national trend of development, deepening of cleaning boiler product design and development. Lulu as a representative of business development of the national beverage, and hope to find a set of boiler energy conservation and clean in one, for drink production process of fermentation, sterilization, drying, curing and other processes. After many visits and market research, in October 2017 and entered into boiler fast boiler purchase contracts, purchase two 10 tons of steam and a whole 20 tons of steam condensing two sets of steam boiler for. The two sides this cooperation is the other quality fast condensing gas boiler highly recognized, has proved a powerful strength fast boiler in the boiler production and service of gas condensate from the side.
Why hot water boiler heating more energy efficient, more environmentally friendly: generally used for heating hot water boilers, but the need to use less steam production process. Biomass boiler categories: biomass boilers Horizontal, vertical biomass boilers. Biomass gas thermal oil heaters, biomass two sets of steam boiler for, biomass hot water boiler, biomass oil furnace. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. Because it is more energy efficient than steam boiler, more environmentally friendly. First of all, in terms of fuel consumption, hot water heating than the steam boiler heating savings of 20% to 40% of fuel, this amount is very impressive. Summed up for two reasons: First, it does not condensate and heat loss due to evaporation of the secondary, two hot water heating pipe is heated by the use of special materials, as thin as possible to meet pipeline needs, heat loss is small. Heat loss due to the steam heating pipe caused by steam leakage large.Free Chat
