malaysia diesel burner for boiler
National Day holiday just ended, Shenyang Environmental Protection Bureau threw himself into the urban environment construction. Before the onset of winter, the Shenyang municipal government will strictly control the air pollution problem. It is reported that Shenyang Environmental Protection Bureau issued out since November 1, Shenyang will strictly enforce the standards of air pollutants emission limits in particular, all the environmental standards of heating enterprises will be cleared out of the heating market.
Shenyang Environmental Protection Bureau issued "on the thermal power industry, coal-fired boilers execution of air pollutants in particular emission limits of the notice" in the next year (the "Notice") requires: Thermal power within the gamut of Shenyang, iron and steel, petrochemical industry and fuel emissions of air pollutants in coal boiler project "thirteen five" period should implement special emission limit standards.
Shenyang is also a good environmental citizen blue sky, Shenyang City this winter and will continue to adhere to "turn point furnace, load shifting blocked arteries," the implementation of standards. After heating units gradually open blocked arteries, Municipal Environmental Protection Bureau will strengthen the routine inspection of law enforcement, and pay close attention to on-line monitoring data 474 coal-fired boilers, boiler emissions of non-compliance immediately ordered to carry out rectification, and severely dealt with strictly waste-water treatment, ultra row of such acts. At the same time, the Shenyang municipal government will also heating units regularly conduct random sampling of coal quality.
It is understood, Shenyang open blocked arteries in succession since October 26 from heating. To ensure that excessive heat stable and safe operation standards, Shenyang will be fully commissioning of heating facilities, to solve problems in a timely manner to ensure the November 1 time blocked arteries heating, the temperature reaches above 18 ℃. After the blocked arteries, Shenyang will strictly implement the winter heating emergency plans to complete the repair within 6 hours general accident, complete repairs within 24 hours more accidents.
Shenyang Environmental Protection Bureau official says, the environmental protection department will be heating business day on-line monitoring, and strictly control their emissions of air pollutants. Over the years, Shenyang has been doing the heating business "remove small and large," the relevant measures, so that some can not afford to increase environmental protection facilities of small companies to large companies merge powerful, let Shenyang municipal heating more environmentally friendly. Strict implementation of the special emission limits of air pollutants standards, both national policy, but also the heating of corporate responsibility, companies must increase investment in environmental protection to ensure the discharge standards.
It is understood that this year, the Shenyang municipal heating will continue to increase the proportion of clean energy, clean coal existing store 230,000 tons, an increase of 30,000 tons last year. Shenyang City, natural gas and other clean energy heating an area of 150 million square meters, clean heating the proportion reached 45%, up 6% over last year. Reduction of 1 million tons of total coal year, 5000 tons of coal-fired boilers to complete denitrification, the city starting from November 1 particularly strict implementation of air pollutants emission limits.
Misunderstandings in cleaning of condensing malaysia diesel burner for 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.
Electric heating hot water malaysia diesel burner for boiler furnace liner made of stainless steel of the advantages of electric heating hot water boiler furnace liner and heat exchanger made of imported SUS304 # stainless steel, water clean, smooth wall and difficult to scale, product life cycle is long (10- 12 years). Heating pipe shell temperature, good chemical stability, corrosion resistant stainless steel seamless pipe for a variety of water; nickel-chromium resistance wire inside is filled with high-density powdered magnesia, resistance wire and sleeve concentricity and even closer to 100% , heat evenly, good insulation; high purity magnesium oxide as a filler, with advanced technology methods and strict quality control to ensure the concentricity of the heating wire. Optimal use watt density design, both to ensure a high working life, but also sufficiently ensure an electrical heating tube expansion and contraction automatic cleaning; U-shaped tube design, only eight millimeters diameter, there is a space between the tube and the tube large, easy to plot scale, leading to the accumulation of impurities and reservoir bag tube burned; cold pin configuration, the nichrome resistance wire welding over a relatively large diameter cooling pin, the pin and the power supply line through a cold pin may be connected to the cold plate to ensure that the lower flange heating tube portion 76 mm long initial unheated portion of the nichrome wire joints low temperature to prevent overheating of the electrical heating tube in the inner part of the pipe joint fitting burned; small size wire port or flange seal good, bring a compact furnace, boiler room and small footprint.
The reason pharmaceutical malaysia diesel burner for boiler gas boiler reason for the choice of selected pharmaceutical boiler gas boiler present, the boiler industry is also relatively fast pace of development, applications in various industries from paper, chemical, food, etc., where the pharmaceutical industry is no exception, with pharmaceutical for example, commonly used boiler gas boiler, then why would pharmaceutical preferred gas boiler it? below small make one simple reason analysis for everyone. Gas boiler pharmaceutical purposes: (1) boiling drying of Chinese herbal medicines (2) of gelatin, the capsule production. Why choose pharmaceutical gas boiler? Under the terms of (1) general case, the drug is used to identify the entrance of drinking, so the quality of the steam requirements are relatively high. The cleanliness of the natural gas itself is relatively high, more in line with standards of the pharmaceutical industry. (2) be suffering in some important time for the water temperature control requires a certain precision, in this regard, gas boiler temperature control more convenient. (3) Since the current state of the environmental requirements are relatively high, as a clean energy gas boiler boilers, boiler geometric other energy emissions of nitrogen oxides, as well as sewage aspect is the better, and in order to comply with national requirements prevail. (4) gas boiler and piping erection only natural gas resources can be put in place, without the need to store fuel, transportation, relatively speaking, to save some operating costs. Of course, this is only part of the consideration of the details of the analysis performed, which naturally has a comprehensive conclusion after analyzing data related to the analysis and comparison of operating costs, for now. Market research point of view, gas boiler market is relatively large, coupled with its own advantages, reasons for the choice of pharmaceutical boiler gas boiler is self-evident.
