什么是贯流锅炉 ，贯流锅炉”是由设计排列的较长管子组成，给水泵在管子一端给水，水(工质)在管内经过加热水段、蒸发段，(过热段)，从管子上集箱产生所需要的蒸汽。它不同于立式水管自然循环锅炉。贯流锅炉没有锅筒，它是由锅炉本体(本体上下集箱、列管等组成)和外部的汽水分离器、水泵、油泵、燃烧器等部件组成。它实质上就是立式直水管燃油燃气锅炉。 贯流锅炉结构紧凑，占地面积小，节约钢材，安全系数大，热（>94%）对大气污染小，烟尘排放符合。锅炉全自动点火、熄火保护、负荷调节、高低水位控制、超压保护等方面，均实现自动化操作，锅炉启动时间短，仅几分钟能达到所要求的运行负荷。 二、贯流锅炉的主要特点： 1、水容量少(1t/h锅炉约为140L)，所以产生蒸汽快，一般产生额定压力下的蒸汽量只需5min左右。因为水容量少，蓄能少，锅炉压力随负荷变化大。这就要求有一套可靠的反应迅速的燃烧自动控制装置及给水装置。 2、由于列管可以自由排列，因此结构紧凑，燃烧方式特殊，使体积大为缩小，但是锅炉炉膛容积热负荷大，水在一根管子内完成加热到蒸发，循环倍率低，接近于1，并有可能传热恶化，产生爆管和疲劳裂纹等故障，所以要求严格控制管壁温度在安全工作范围内。 3、这种锅炉结构紧凑，维修性差。贯流锅炉本体几乎不可能维修的。一旦损坏，只有更换新炉。这就要求严格控制制造质量，执行严格的质量管理体系，制造厂要出合格的高质量产品。同时它对给水水质要求较高，应严格控制给水水质标准，以保证其使用寿命。 4、钢材耗量小，贯流锅炉的钢材耗量与单位产汽之比为1.1：1(即1.1吨钢／吨汽)，而普通燃煤锅炉约为4—6吨钢／吨汽。 5、一般认为，这种结构形式的锅炉，其蒸发量适合在4t／h以下。如果再往上增大容量，它与其他形式的锅炉(如卧式内燃锅炉)相比优越性小。这种锅炉常只做到2t／h。国内容量一般在3t／h以下
What is a tubular boiler, tubular boiler "is long tube designed by arrangement of the composition, the feed water pump in the water supply pipe end, water (fluid) in the tube after heating water section, evaporation section, (superheated section), from pipe header steam needed. It is different from the vertical water tube boiler with natural circulation. Tubular boiler do not drum, which is composed of a boiler body (body on the lower header, column tubes) steam separator, water pump, oil pump, such as burner components and external components. It is essentially a vertical straight tube fuel and gas boiler. Tubular boiler has the advantages of compact structure, small occupation area, steel saving, high safety factor, high thermal efficiency (> 94%) on air pollution, dust emissions in line with national standards. Boiler automatic ignition, flame protection, load control, water level control, overpressure protection, realized the automatic operation, the start-up time is short, to run load required only a few minutes. The main characteristics of the two, tubular boiler: 1, less water capacity (1t/h boiler is about 140L), so the steam fast, generally produced steam under rated pressure only about 5min. Because the water storage capacity is less, less, boiler pressure with load variation. This requires automatic control device and supply a reliable quick combustion device. 2, because the column pipe can be arranged freely, therefore has the advantages of compact structure, combustion special, so the volume is reduced, but the boiler furnace volume heat load, water heated to evaporate in a single tube, circulating rate low, close to 1, and is likely to heat transfer deterioration, the tube burst and fatigue crack fault so, strictly control the tube wall temperature in safe working range. 3, the boiler has the advantages of compact structure, poor maintainability. Tubular boiler body is almost impossible to repair. Once damaged, only the replacement of the new furnace. This requires strict quality control, strict implementation of the quality management system, manufacturing plant to high-quality products qualified. It requires also higher on the water quality, should strictly control the water quality standard, to ensure that its service life. 4, the steel consumption, tubular boiler steel consumption and unit steam production ratio of 1.1:1 (i.e. 1.1 Dun Gang per ton steam), while the ordinary coal-fired boiler is about 4 - 6 Dun Gang / tons of steam. 5, generally, this kind of boiler structure, the evaporation is suitable for 4T / h. If you go on increasing capacity, boiler and other forms (such as the Horizontal Internal-combustion boiler) compared with the superiority of small. This boiler is often only do 2T / h. The largest capacity in general 3t / h
