Water Tube Boiler vs Fire Tube Boiler is comparison between two types boiler which is viewed from several aspects. Water tube and fire tube boiler is mobile steam boiler for sale classification which is categorized based on tube type.
Waste boiler damage and over-temperature overpressure maintenance program to ensure the normal use of the waste heat boiler, to conduct strict monitoring of the temperature of the device, pressure, steam production, etc., to prevent over-temperature overpressure operation, not to ensure that the main production of chemical products , while ignoring the protection of the waste heat boiler, waste heat boiler eventually cause damage, forcing the total unit shutdown. When repairing a waste heat boiler for a petrochemical plant, found in the high-temperature side of the large number of burst pipes. The reason for the investigation, mainly towards the end of the year to ensure the completion of production tasks, and increased work load, resulting in over-temperature overpressure operation, leading to over-burning furnace tube, resulting in burst pipes. Improper waste heat boiler water treatment boiler is also one of its water supply must meet the requirements of the boiler water. In some plants, due to various reasons for this request seriously enough, that is not always the main equipment products, ignoring the quality control of its water supply, resulting in huge losses. After careful analysis of the structure of the apparatus and observe damage, following observations were made: (1) the waste heat boiler tubes up to 10m, the low temperature furnace tube plate and tubes are welded structure expansion. Out in the field can not damage the tube, it must be removed to send repair factory repair; (2) must make sure that the new exchange tubes of the high temperature-side pipe plate 3mm protective layer of water, with water to ensure the protection tube sets of concentric. And the best way to ensure 3mm protective layer of water that is the case not to cut, just out of the old pipe, can be replaced with a new tube. Accordingly, development of a repair scheme as follows: (1) to both sides of the tubesheet bore boring furnace tube head, to ensure that each of the furnace tube to tube plate separator. In which the lower tube plate, the tube plate to ensure = 14mm 57mm concentric to the hole on the high support and forging; the upper tube plate, to ensure that the upper tube plate and tube weld is disengaged. (2) the old tube out from the tube sheet on the lower lateral sides of the tube plate to the tube plate punched up = 290mm hole. (3) withdrawing furnace tube damage, one requires pumping a barrier to prevent misalignment baffles within the housing. (4) the centering ring on the new tube welded end to ensure that the new tube after penetrating the tube plate, the aqueous homogeneous = 3mm protective layer profile. (5) penetrate new furnace tube, tube wear new requirements in place a good spot, take out the old furnace tube between the two new tubes. (6) the tube plate TIG welding, particularly welding node and Welding. Wherein the upper tube plate using fillet welding, using a lower tube plate bore welding. (7) the tube plate on the furnace tube after welding expander. (8), the lower tube plate weld stress relief treatment. (9) the tube / plate welds colored 100% inspection, hydrostatic testing. Following the above repair process waste heat boiler has been running more than a year, currently running in good condition.
When the raw gas boiler water as surface water, purpose of the pretreatment is to remove suspended solids, colloids and organic matter and the like. Usually raw water coagulant (such as aluminum sulfate, etc.), so that the impurity into larger agglomerated particles, sinks by its own weight, and then filtered into water.
Fast boiler has been to uphold the "mold character, and create boutique" business philosophy, after learning of the status of the state forest mountain elementary school, we are non-stop, quickly prepare a large number of teaching supplies, to the mountains in order to improve children's education hardware conditions positive contribution. In order for children to drink purified water clean and sanitary, after the group discussion after deliberation, determined to provide six sets of water purification equipment and pipeline machine. Teachers and students by means of this device can drink safe water purification, we can say that they know how these "water" next to the Red Flag Canal precious. Watching the children line up smiling face after the contact of water, we all feel distressed bursts.
