Misunderstandings in cleaning of condensing boilers and their improvement measures

During the manufacture, transportation and installation of the condensing boiler directly supplied by the new factory, the inner wall of the condensing boiler is concentrated with oxide or other dirt, which causes the condensing boiler to be corroded by the hot surface during its initial operation. Therefore, a series of measures should be taken to ensure the cleanliness of the condensing boiler when it is installed and ready to run. So in the process of consumer cleaning, what mistakes will be misplaced, and how to use it correctly?

1. there is no chemical analysis in the process of chemical cleaning: chemical cleaning is a very rigorous process. But if the chemical cleaning is not complete, some of the dirt has not been completely cleaned; and if the cleaning time is too long, Wash phenomenon will occur; cleaning effect is not good, secondary cleaning will waste raw materials, and delay time. The phenomenon of excessive washing will aggravate the corrosion of condensing boiler, cause the metal bearing capacity of condensing boiler to decrease, and affect the normal operation of condensing boiler. The improvement measures are: must do the chemical analysis detection in the chemical cleaning process, every ten minutes to test the acidity, the total iron ion concentration, the PH value. When the two analytical data are close, the chemical cleaning reaches the end point, neutralizing the acid solution to the neutral and then discharging.

2. no passivation after chemical cleaning: passivation process is actually a clean condensation boiler body surface and passivation agent re-reaction process. Because the control point of passivation is more strict, if the control point is not well controlled, the passivation will fail, and if the pickling is finished, only simple neutralization will be carried out, and the cleaning will end, which makes the surface of the cleaned condensing boiler easy to produce secondary floating rust. The scale-inhibiting ability of condensing boiler is reduced, which makes it easy to rust. The improvement measure is to rinse and passivate the condensing boiler after pickling. Because the passivation requirement is relatively strict, the concentration of total iron ions must be strictly controlled in the rinsing process. Rinse After finishing, the pH value should be adjusted to strong alkalinity immediately after the iron ion is detected, and the passivation agent should be added to passivate the temperature.

Smoke tube boiler working principle:

To aid circulation the tubes are arranged in vertical rows to offer minimum resistance.

Shunde main business of special sea oil production and processing, etc., in the course of special oil refining, a large amount of steam required for oil and gas extraction, distillation and extraction technology and other aspects, therefore, the boiler is supplied special sea oil processing technology company Shunde indispensable less equipment. As environmental policy progresses, the chemical industry as more polluting industries are highly valued the various departments of quality supervision, sea Shunde companies to follow the development of the State Environmental Protection pace, choose clean the boiler industry-leading fast Boiler cooperation with the parties by quickly assess the specific needs on-site estimates and sea Shunde, to provide a SZS series of 25 tons of steam water tube low pressure vertical fire tube steam boiler for sale (SZS25-2.0-YQ).

Environmental trends at this stage of the boiler, energy-efficient premise is the development of environmental protection industries, all pollute the environment, feel free to use the production of non-renewable resources are not allowed, boiler industry is the same. Today we'll look at the development trend of environmental protection boiler. To further strengthen air pollution control, safeguard people's health, and improve ambient air quality, enhance the level of ecological civilization construction, the boiler is also developing towards the direction of environmental protection. At present, the boiler industry in China energy-saving environmental protection industry, the presence of small-scale enterprises, poor financing, technological research and innovation is not enough, the market order is not standardized and other issues. Insiders suggested that the development of energy-saving environmental protection industry can explore energy conservation and environmental protection equipment manufacturing and modern service integration model of development, to encourage the advantages of energy saving equipment manufacturing enterprises through mergers and acquisitions and other ways to extend upstream and downstream industry chain, formed a set of engineering design, equipment manufacturing , operation and management in one mode of operation, promote the rapid development of environmental monitoring, environmental engineering consulting and other related services. With dwindling non-renewable resources, the rapid rise in energy prices, coupled with the nation and the world the importance of environmental protection, energy saving, since the five-year plan, building a resource-saving and environment-friendly slogans have been proposed, the development of boiler market began to develop from extensive development to energy saving and environmental protection.
