Nongfu Spring has been committed to the production of natural and healthy drinking water, only after a simple filtration, without changing the water quality, maintain natural water features indicators, unswervingly follow the environmental, health, natural path of development. Fast horizontal style and steam output boiler since its inception, focused on research and development of clean boiler design, adhere to the concept of environmental protection has become condensing gas boiler industry leader. The same faith, the same dedication to promote fast boiler and Nongfu Spring work together to create new environmental future.
Regular inspection of horizontal style and steam output boilers 1, external inspection, usually once a year, this test is in the operating state of the boiler, check the safety accessories, automatic control instruments, protection devices are sensitive, reliable; joints with or without compression component leakage phenomenon; also check the relevant rules and regulations in particular the management of water quality and the implementation of the rules and regulations established. Check the contents of the existing concrete visible external inspection requirements. External inspection has a direct role in preventing accidents. 2, the internal check: every two years a transfer. This test is to conduct a comprehensive internal and external boiler inspections to stop running in the boiler state. The main defect inspecting various boiler heating surface forming operation, such as wear, corrosion, fatigue, deformation or the like, but also to check the security status of the attachment. Specific requirements visible check the current national regulations. 3, hydrostatic test: general once every six years. That can not carry out internal inspection of boilers, pressure test every three years. 1) hydrostatic test pressure should meet the following: the name of the boiler working pressure P test pressure boiler 0.8MPa1.5P, but not less than 0.2MPa boiler 0.8-1.6MPaP + 0.4MPa boiler> 1.6MPa1.25P any pressure superheater the same test pressure boiler body and separable any working pressure economizer 1.25P + 0.5MPa2) and the hydrostatic test requirements of the basic steps: the boiler pressure test, pressure should slow down. First, the cabinet lead off the burner, it can not work. When the pressure rises to the pressure of work, should be suspended boost, check for leaks and other anomalies, and then boosted to the test pressure. Boiler should be maintained for 20 minutes at the test pressure, and then down to the working pressure checked. During the inspection the pressure should remain unchanged. Hydrostatic test shall be carried out when the ambient temperature is higher than 5 ℃, antifreeze measures must be less than 5 ℃. Water pressure test should be maintained above the dew point temperature of the surrounding surfaces to prevent condensation boiler, but it should not cause the high temperature vaporization and to prevent excessive temperature stress, is generally 20 ~ 70 ℃. 3) passing the test pressure condition: 1, there is no pressure on the walls and the weld metal element and the mist droplets; 2, when the working pressure drops mouth inflation does not drip; 3, hydrostatic testing, no residual deformation was found.
The improvement of horizontal style and steam output boiler thermal efficiency is considered by many users. It is believed that this problem is the research direction that every boiler manufacturer has been studying. When many users operate the boiler, they often find some new problems in the actual production process, but among all the problems, the most troubling thing is the phenomenon of higher exhaust temperature and lower thermal efficiency of the boiler. This phenomenon seriously affects our normal work, so what can we do to improve its thermal efficiency? What we need to know about this is that the best fit for low-temperature characteristics is synthetic molding. However, most of the synthetic molds are biphenyls, both of which are composed of biphenyls Complex benzene derivatives, whose vapors or their volatiles are highly carcinogenic, are strongly advised to choose oil-based products. Secondly, in the process of meeting the low temperature performance, the product also has a relatively high flash point requirements. In general, engineers recommend that the low-temperature opening flash point should not be below 200 ℃. Through the continuous research and improvement of its equipment by professional manufacturers, it is found that in order to improve its thermal efficiency, it is necessary to increase the heating surface at the tail of the boiler, such as air preheater and economizer. However, when the backhaul temperature of the organic heat carrier furnace body is very high, the economizer can not be installed, but the air preheater can only be installed to alleviate the situation. So if the boiler does not exchange heat with other low-temperature heating systems, the only way to improve energy efficiency is to add air preheaters. After adding air preheater, the velocity of flow can be increased accordingly, so as to ensure the boiler to work safely, reliably and stably, and the thermal efficiency of boiler equipment will be increased accordingly.
