What are the problems shell type fire tube boiler water treatment chemical? What are the problems boiler water treatment chemical? Water equivalent blood boiler boilers, boiler water treatment purpose is to prevent corrosion of boiler scale to ensure normal water boiler, steam boiler to ensure good quality, so as to ensure boiler safety, economy, energy-saving operation. In recent years, with the wide application of large boilers, boiler in a major accident, the accident caused due to improper handling of water accounted for about 75% water mishandling become the biggest risks of major accidents boiler, at the same time, the scale caused by the energy loss also incalculable, according to the relevant studies have shown that the scale boilers for each additional 1mm, boiler fuel increased by 8%, while productivity declined by 5 percent, boiler water treatment has become a major problem to be solved in boiler management. Chemical plants by strengthening standardized management of boiler water treatment, one can prevent and reduce the occurrence of fouling boiler water, reduce boiler corrosion damage, improve the quality of steam, on the other hand can promote more energy-efficient boilers, environmentally friendly, economical operation. In this article, the author in accordance with the water treatment chemical inspection and periodic inspection of industrial boilers, combined with the actual situation of the low-pressure boiler water treatment chemical, water treatment chemical analyzes the main problems existing in the work of industrial boilers, and propose appropriate the countermeasures. Existing chemical plant boiler water treatment Question 1, the water quality of a lot worse chemical plant boiler feed water, they use tap water or groundwater, however, water and ground water, water is a high hardness, poor general water quality. And high water hardness scale easily Boiler green, endangering the safe operation of the boiler, waste of fuel. Poor water quality in the region, the operation of the boiler occur drum kits, burst pipes and other accident probability is much higher than in other regions. 2, the water quality is not widespread testing, boiler water treatment equipment, chemical plant utilization rate is very low, most are not equipped with full-time staff of boiler water treatment, whether without the required boiler feed water quality testing in line with national standards, to water treatment equipment, there is no follow-up observations at any time, so often unable to determine whether the normal operation of equipment, equipment for resin contamination, as well as the loss of equipment, etc., failed to timely detection and timely treatment, so that the water quality of the boiler are generally not ideal. 3, water treatment equipment, quality standards, do not attach importance to the quality of water treatment equipment, water treatment equipment testing is now available in the market is uneven, with cut-throat competition, resulting in quality standards of water treatment equipment flooded the market. And boiler inspectors in the boiler inspection, often overlooked acceptance of water treatment equipment, processing power and boiler water treatment equipment matches and other issues do not pay attention. 4, lack of professionals, water treatment work blindness large chemical plant boiler unit ubiquitous phenomenon does not attach importance to water treatment works, water treatment personnel can not guarantee that excellent professional knowledge and skills. Currently, the city of boiler water treatment by the staff mostly part-time fireman, most do not have specialized knowledge of water treatment, water treatment did not grasp the principles of performance needed for drug treatment, the frequency of administration and dosing method of so I do not understand, also failed to fully grasp the working methods of water treatment equipment, thus resulting in indiscriminate use of drug misuse and other phenomena often occur, for boiler water treatment brought great damage. In particular pot of water treatment method, if done incorrectly, it can cause even counterproductive, but also easily lead to damage to the water treatment equipment. 5, low or backwater condensate recovery steam boiler not be recovered without treatment chemical plant in the vast majority of condensate steam boiler, resulting in waste of water, heat loss, energy-saving environmental protection do not meet the completion requirements. Only a few steam boiler condensate to a recovery, but untreated, cause corrosion backwater system, resulting in a high iron content of the condensed water, causing water and muddy redness, increased heating surface tube furnace electrochemical corrosion occurs risk.

Qinghai pressure shell type fire tube boiler pressure boiler factory currently produces a lot of manufacturers are, for the procurement of boilers companies, must be to boiler manufacturers nationwide comparison, not confined to local businesses a boiler. After all, now, the boiler's transportation problem is not a problem. Recently, there is a business consulting to fast boiler Qinghai want to buy a pressure boiler, the beginning of time is selected pressure boiler manufacturers in Qinghai, however, on the current situation, the situation is far from ideal choice of. So, only then choose to expand the scope of the country, so consult with fast boiler. After fast boiler technician after a detailed accounting of the enterprises in Qinghai, marriage is derived from the plant with a boiler pressure boiler units 1 2 t is possible.
