Tubular Tubular boilers oil boiler gas boiler Tubular Tubular what is tubular boiler boiler price, once-through boiler "is composed of a long tube arrangement designed to pump water at one end of the pipe, water (working fluid ) after heating the water in the pipe segment, evaporator, (overheating), the steam generated from the upper header pipe needed it differs from the vertical pipe natural circulation boilers. tubular boiler no drum, it is by boiler ( upper and lower body set box, tube etc.) and external separator, water pumps, oil pumps, burners and other components, which is essentially vertical straight pipe oil and gas boilers. compact tubular boilers, small footprint, save steel, safety factor, high thermal efficiency (> 94%) of the small air pollution, dust emissions in line with national standards. boiler automatic ignition, flame protection, load regulation, low water level control, over-pressure protection, etc., are automated operation boiler start-up time is short, only a few minutes to reach the required two operating load, the main features of tubular boiler: 1, water capacity less (1t / h boiler of about 140L), thus generating steam quickly, generally produce the rated pressure Just the amount of steam under 5min or so. because less water capacity, less storage, boiler pressure with load changes, which requires a set of reliable and responsive automatic combustion control device and water supply installations. 2, due to the freedom tube arrangement, so compact, combustion special, so that the volume is greatly reduced, but the boiler furnace heat load large volume of water is heated to evaporate completed within a tube, circulation ratio is low, close to 1, and is likely to worsen heat , burst pipes and produce fatigue cracks and other faults, it requires strict control of wall temperature within safe operating range. 3, compact structure of this boiler maintenance is poor. tubular boiler is almost impossible to repair once damaged, only replace the new furnace, which requires strict control of manufacturing quality, the implementation of strict quality management system, the manufacturer of high-quality products to be qualified. while its high quality requirements of water supply, water quality standards should be strictly controlled to ensure that its service life. 4 , steel consumption is small, tubular steel consumption and unit boiler steam production ratio of 1.1:1 (ie, 1.1 tons of steel / ton steam), while the average is about 4-6 per tonne of coal-fired boiler / ton steam. 5 is generally believed that such a structure in the form of boiler, its evaporation suitable 4t / h or less if the upward increase capacity, it is compared with other forms of boiler (eg horizontal internal combustion boiler) superiority small. This Boilers often just do 2t / h. largest capacity in general 3t / h or less Henan Silver morning Boiler Group Co., Ltd.
