school natural gas vacuum boiler dealer in Hoi An

Boiler feed water is necessary to control item 1, suspension criteria: When the school vacuum boiler dealer in hoi an feed water of the raw water from surface water, depending on the number of suspended solids and colloidal content in water, can be selected coagulation, sedimentation and filtration techniques; when the raw water is groundwater, general just filtration, which is high iron content, increased iron manganese sand filter measures. 2, standard hardness: mainly many ways to prevent or control fouling, hardness removal, lime softening, softening agents exchange, but the most common, is the best approach to ion exchange softening effect, newer methods nanofiltration is law. 3, dissolved solids standard: When the salinity pot of water reaches a certain limit, it will generate priming, resulting in a sharp deterioration in the quality of the steam boiler. Many water quality demanding industries, such as the electronics industry and power plants and other boilers with high pressure, dissolved solids of the water has more stringent requirements. Method of reducing dissolved solids generally referred to as desalting, the main methods are: ion exchange, electrodialysis, reverse osmosis, the traditional process to use an ion exchange method, a method for updating a reverse osmosis membrane method. 4, DO standard: DO is mainly to prevent the corrosion of the furnace and the duct, the general heat deaerator, there are other oxygen chemical, electrochemical oxygen, vacuum deaerator like. 5, PH value and alkalinity boiler water standards: when boiler water is alkaline (pH 10-12), in order to make the fouling substance becomes slag to clear. Commonly used dosing method. 6, the relative standard alkalinity: primarily prevents the generation of caustic embrittlement. - scale boiler cleaning equipment, boiler feed water equipment, boiler water softening equipment, boiler desalted water softening device 7, the standard oil content: boiler water is mainly to prevent foaming, with formation of oily scale. Techniques employed degreasing water separator and the like. In cities and towns, the boiler feed water is generally tap water as raw water, drinking water according to the national standard, which turbidity is not more than 5, the total dissolved solids <1000mg / l, PH = 6.5-8.5, no oil, generally only the hardness of the boiler does not meet the standards water supply requirements, for industrial low-pressure boilers and hot water boilers, only the configuration softening process.

Factors influencing the performance of the vacuum school vacuum boiler dealer in hoi an which 1) the boiler body, the valve, the instrument no leaks. At present, including imported equipment, including valves and no guaranteed not to leak occur within three years. 2) Whether the control section has failed, and the negative pressure controller boiler controller will inevitably fail in operation, for example, the failure rate controller made even higher. 3) vacuum pumps, three-way solenoid valve, the device is working properly, because the vacuum pump, three-way solenoid valve does not run often, too easily imported stuck and run. 4) should not be a sudden change in load. Boiler load change is normal. Boilers generally such that 30% to 100% load regulation.

Industrial school vacuum boiler dealer in hoi ans is a major driving force for social development, but also brought great pressure on the environment. Whether coal-fired boilers, biomass boilers, or, when the supply of energy, the emission of pollutants will soot and nitrogen oxides. Some enterprises in order to save costs, the pursuit of more profits, but also allowed to change the fuel, biomass boilers burning coal steal, wood, and even garbage doping or other industrial waste, produce dioxins and other carcinogens directly into the atmosphere after combustion, pushing PM2.5 concentrations.

Since started Blue Sky Battle horn Guangdong Province, many cities have begun to respond positively, Dongguan City, is one of them. Atmospheric do in-depth business thoroughly, and the development of industrial boilers business accounting, confirming the city's need to eliminate highly polluting boilers have 765 units, of which 728 sets of biomass boilers, 37 coal-fired boilers. Subsequently, promote the transformation of facilities operations out of high pollution boilers within the city.

As of May 14, 2019, the city's 324 enterprises active removal of 363 coal-fired boilers burning biomass, as well as 83 to 84 companies demolition of the old boiler pipes, 447 completed phase-out plan of the boiler in advance.

Although there are many companies take the initiative to carry the main responsibility for the ecological environment, but there are still some chances enterprise.

Atmospheric Office official admitted that "in the daily inspection, the company found that some still illegal use of boilers, perfunctory 'coal to gas' work." Among them, although some enterprises written off coal, biomass fired boilers, but because of natural gas boiler installation behind schedule, forced production needs, but to let the old boiler continues posts. There are companies more "capricious", install two-way pipeline for new and old boilers, strict supervision when using gas-fired, law enforcement officers continue to take a coal burning biomass. There are even companies deliberately delayed "from coal to gas," progress, choose to enable the original write-off of the boiler.

This year, the Office of Atmospheric inspection personnel to go to 244 companies in the field to check the boiler usage, found that 42 enterprises there is illegal use of boiler problems. Among them, there are 18 companies of illegal use of biomass boilers has been canceled. "Not only pollute the atmosphere, there are still significant safety risks." Atmospheric Office inspection personnel Lurui Quan said, "the city's coal-fired, burning biomass boilers as well as 113 units, involving 94 companies, is expected to complete phase-out year, access to clean energy. "simple behind the data, there is a thick ledger out of the transformation of the boiler," when removed, when write-off, out of a pin number one glance. "

Atmospheric Office official also said the recent city towns Street (Park) Atmospheric Office will carry out investigation and remediation special action has been canceled boiler, supervise and guide enterprises to demolish the old boilers and pipes, put an end to "note not sell" phenomenon. At the same time, urge enterprises will have been dismantled boiler dedicated to the sale of scrap recycling company, effective way to solve the old boiler, complete eradication of pollution and safety hazards.

Boiler explosion: school vacuum boiler dealer in hoi an accident points boiler and furnace two parts: an accident of boiler body is divided into five categories: crack, shrink flat, burning, swelling, cracks. The furnace in the fuel gas explosion accident. Which is hereby cause of the accident occurred and the case are as follows: Burst (called Rupture): boiler, due to negligence of the operator, or pressure allowed, or due to corrosion thinning, beyond their actuation can bear pressure, thus generating burst. Condensing flat (Collaps): Because the water level is too low, resulting in loss of overheating, cold water added suddenly, so that the steam condenses into water pot, is the volume is reduced to a vacuum, such as poor support, could not bear the atmospheric pressure outside, i.e., causing shrinkage flat. Burning (Burning): mostly burnt in the furnace tube, pipe and cigarette tobacco tube to tube plate joints. The reason for the operator to add too much fuel, the fire caused by excessive; or by the lack of capacity of the boiler, causing fuel to pay more due to the raging fire. Swell (Buldge): This is because the oil within the boiler or scale pan is attached to the steel plate or the heat can not propagate, causing local overheating (LocalHeating), decreased material stress plate soften, resulting in swelling phenomenon. Cracks (Crack): This is because: the boiler water is too alkaline formed caustic embrittlement (CaustivEnbrittlemnt). The steel material caused by impurities such as oxygen-containing laminate (Lamination). Thick steel plate, temperature difference is too large, the thermal expansion and contraction caused by stress corrosion, known as erosion groove (Grooving). As the gas blast furnace, the use of oil-based, gaseous fuel, exhaust gas poor, and the explosive range of the gas, causing an explosion.
