多烟管立炉式换热器多烟管立炉式换热器实质上是容积式换热器，结构形式上与普通热水锅炉相同，40年代改进成为多烟管，使换热面积增加，热效率也能超过90，应用强排烟机，使用折烟片，让热烟气在烟管内流速增加，并使烟气流动方向与内壁形成大角度。
Smoky vertical tube type furnace for heat exchanger（www.hreqi.com） smoke tube furnace heat exchanger essence is volumetric change heat exchanger, structure form and ordinary hot water boiler of the same, in the 1940s improved to become smoke tube, and the heat exchange area and increasing, thermal efficiency can exceed 90, the application of strong exhaust hood, folded leaves, let hot flue gas in pipe flow rate increased, and the formation of large angle of the direction of gas flow and the inner wall.
这种换热器的烟管竖直向上，再加上风机的强抽，热烟气在烟管中流速较高，没有死角不会沉积烟尘灰污。所有受热面都与水接触，高温火焰直接接触的换热面，受热也不严重，使用铜材料也不用保护（必须用脱氧纯铜）。因此，在受热面上不易产生也不易沉积烟尘灰污。长期使用，热效率几乎不下降。由于容积式换热器有较大的容量，不会产生后沸现象，在有过热保护的情况下，可长期不结垢。
The smoke pipe of the heat exchanger is vertically upward, and the upper side of the upper side of the upper machine is strong, and the heat fume is higher in the smoke pipe, and no dead angle can not deposit the soot and ash. All heating surface in contact with the water, high temperature flame direct contact heat transfer surface, heat is not serious, the use of copper materials also don't have to protect (must be deoxidized copper). Therefore, the heating surface is not easy to produce and is not easy to deposit soot and ash. Long term use, thermal efficiency is almost no decline. Because the volume type heat exchanger has a larger capacity, does not produce after the boiling phenomenon, in the case of overheating protection, can not be long-term scaling.
比如翅片管式换热器，只有在有了燃气翅片管式换热器，有了水气联动控制系统，翅片管换热器才能应用于热水器中，燃烧方式与控制方式及换热方式的任何改革都是相互影响的，如果没有半大气半鼓风这种强化燃烧器，容积式的换热器也很难做到小型化而用于壁挂炉上。启东沪星中央空调清洗公司针对水质情况，通过试验，筛选出有机嶙系复合水处理药剂配方。
Such as fin and tube heat exchanger, only in the gas finned tube type heat exchanger, water gas linkage control system, transfer of finned tube heat exchanger can be applied in the water heater, and control of combustion and any reform the way of heat transfer are mutual influence, if there is no semi gas blast the intensified burner, volumetric heat exchanger is also difficult to achieve miniaturization for wall hanging furnace. Qidong Huxing central air conditioning cleaning company for water quality, through the test screened organic farms, composite water treatment pharmaceutical formulations.
该配方具有缓蚀剂和阻垢剂双重功效，又具耐高温，不易水解等性能，使用也很方便。配方中的丙烯酸经丙醋共聚物，属分散型阻垢剂，能包围水中的胶体颗粒而达到分散阻垢的目的。有机磷盐属鳌合型阻垢剂，由于分子中含有经基，磷酸基所以能与水中的钙、镁等离子形成稳定的络合物，达到鳌合阻垢的目的，有机瞬酸盐还有较好的缓蚀作用，它是一类参与或膜的阴极型缓蚀剂，它和离子的络合作用比聚磷酸盐更为稳定，因此保护膜更为牢固。
The formula has the advantages of corrosion inhibitor and scale inhibitor, and has the advantages of high temperature resistance, easy hydrolysis, etc., and is convenient to use. The acrylic acid in the formula is a dispersion type scale inhibitor, which can surround the colloidal particles in the water to achieve the purpose of dispersing and scale. Organic phosphorus salt is a chelate type antisludging agent, because the molecules containing the base and phosphate so can water with calcium and magnesium ions formed a stable complex, so as to achieve the purpose of chelating scale, transient organic acid salt and good corrosion inhibition, it is involved in or membrane cathode corrosion inhibitors, and ion complexation than poly phosphate is more stable, so protective film is more firm.
