Boiler feed water is necessary to control item 1, suspension criteria: When the boiler 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.
Hot water boiler tank size is defined determinants and small boilers: hot water boiler, which is a boiler, and, for common and common species, therefore, be familiar with and understand it, is necessary, because in practical work may encounter and use this kind of boiler, therefore, we will have the need to know. And here are some specific issues to expand through this work. In this way, we are also capable of deriving some expertise, rather than nothing. 1. The hot water boiler tank, its size is determined by what? Hot water boiler tank, which should refer to the boiler tank with the water pipe network, rather than directly to the boiler water tank is mainly used to store oxygen or demineralized water. The tank capacity is determined by the size of the fill water of the hot water boiler. In the design of the boiler, is generally calculated according to the cycle of water 3% -5% of the fill water boiler system. 2. The need to gauge pressure hot water boiler in? In addition, vacuum gas boiler, hot water boiler which is it? Pressure hot water boiler, which is a hot water boiler, which boiler the host, there is communication with the atmosphere of the conduit, so that the boiler remains at normal pressure. So, this kind of boiler, does not require installation of a pressure gauge. And vacuum gas boiler which are generally hot water boiler.
5,000 square meters of hotel heating choose how much vacuum heating boilers in Tianjin yesterday to have a customer is to open the hotel, called me and said his hotel consulting want to buy a heating and hot water boilers, used to use the air conditioning and electric heating water heater, carefully doing too expensive, so I want to replace the boiler, the customer said a total of 246 rooms, plus hall, etc. these all need to use heating, we ask this question for the next Zhang business unit, in accordance with standard hotel housing area about every room of the area is 20 square feet, of course, does not rule out some of the relatively large area, but the normal ratio is 20 square we are also counted in accordance with this ratio, the price of heating surface 246 rooms for 4620 flat, count the hall and other staff of almost 5,000 rooms flat, guest bath water, not bathing hall, average room to count the guests bathing water is nobody about 50 kg, the lowest number since almost all 2 accommodation personal Therefore, we calculated according to two standards, water 50 * 2 * 246 = 24,600 kg, then it is because it is a gas boiler for The amount of demand is not great, but there are also certain requirements, ranging from 0.35MW ~ 14MW power in general. So sum of 5000 level of heating and hot water need to use a vacuum hot water boiler 4 tons, and because of this production in Henan party fast heating and hot water boiler is bidirectional, a boiler can solve two problem! For more on how much a flat area with a vacuum boiler please contact customer service online, we will provide you with free programs and solutions!
Exhaust gas has been plagued by sewage paper industry, paper industry pollution problems of the country very seriously. Fujian Heng paper packaging company has been committed to the use of clean-type boiler paper processing. October 22, 2016, David Carse, the paper with my company, signed a 6 tons of steam an integral condensing steam boiler for the production of corrugated cardboard and other paper products. I provided the boiler greatly solve the problem of sewage wastewater Heng paper. After the boiler operation, both to meet local environmental requirements, but also reduce operating costs for the constant boiler paper products.
