Different types of fuel industry vacuum boilers vacuum phase transition characteristics of the current vacuum phase transition boilers can be classified according to different forms of fuel, this method is easier for people to select and purchase. With increasing depth of industrialization and people's needs, the market share of vacuum phase transition boiler is increasing. Characteristics of different types of vacuum phase transition boiler determines its optimum position. Based on this situation, we should be aware of the classification and various other functions, therefore, the right choice. We will discuss the characteristics of vacuum phase transition boilers of different types. Different types of fuel vacuum phase transition phase transition characteristics of the boiler vacuum boiler may also be referred to as a vacuum boiler. Its working principle is vacuum phase transition and phase change. The fuel can be divided into four categories, but can be divided into three categories and a category, it can be divided into two categories, and describes the characteristics of each fuel. (A) an electrically heated boiler vacuum phase transition phase transition in the electric vacuum heating boiler in operation, the vacuum in the internal environment. Since the electric vacuum phase transition boiler water will be discharged to the outside of the oxygen-containing, oxidative corrosion of the boiler does not cause damage to the device. Meanwhile, the electric hot water boiler heat exchanger portion of the vacuum made of stainless steel does not corrode. Further, only one electric vacuum hot water boiler heat medium plus a small amount of water, does not increase or decrease the run, no fouling. (B) fuel (gas / coal) boilers vacuum phase transition phase transition such a vacuum inlet boiler burners, high combustion efficiency, low noise and emissions. Internal stainless steel heat exchanger, on the one hand to ensure that the heat transfer efficiency, on the other hand to ensure that the clean water. Meanwhile, also equipped with a spiral spoiler, improve the heat transfer efficiency and reduce operating costs. Further, a square structure, boilers and heat exchangers designed as compact structure, small volume.
Enterprises in the selection of vacuum hot water industry vacuum boiler needs to pay attention to what vacuum gas hot water boiler as the future development trend of the civilian boiler, safe, free inspection, easy to operate, by the majority of boiler users. Like traditional boiler, the boiler in the selection process, in addition to quality and price factors, but also need to pay attention to the following factors: fuel vacuum hot water boiler: When selecting a vacuum hot water boiler, first thing to consider is what fuel combustion. This gas combustion boiler both, but also light diesel oil combustion. In terms of environmental protection and convenience, it is recommended to use natural gas procurement business as boiler fuel. Evaporation in vacuo of the hot water boiler: may be referred to herein evaporation boiler load, i.e., steam or hot water required by the user, the unit may be t / h that the rated capacity of the vacuum hot water boiler is 0.56t / h in vacuo. hot water boiler heat exchanger: compared with a conventional boiler, vacuum hot water boiler heat exchanger inserted in the upper half of the vacuum vapor chamber. Select the heat exchanger needs to be determined according to the user a boiler. It is divided into three heat exchangers, ABC, heating, hot water, hot water process for different purposes.
2. industry vacuum boiler technology energy-saving measures (1) strengthen the technological transformation of inefficient boilers. Due to our limited economic base, not all older boilers have been updated. For updates not included in the scope, efficiency is not high but there are more defective boiler should strengthen technological innovation. Technological transformation of industrial boilers, should try to achieve a multi-effect of the change is necessary to improve the thermal efficiency to save fuel, but also to increase output, reduce pollution and achieve civilized production, but also to adapt to burning low quality coal. (2) boiler should make full use of frequency control technology. When selecting the boiler pump and fans, are considered certain margin in the rated load, so that in fact the boiler operation, the fan and the pump flow is less than the rated flow equipment, are required to be adjusted. Is adjusted by adjusting the throttle in the past, i.e., OFF or the throttle opening degree smaller Importers baffles, the flow rate is reduced, but not significantly reduced motor power. Frequency is reduced by the drive motor speed, the motor output power decreases. Frequency control for pumps and fans, general can save 30% to 40%, the investment can be recovered through two heating season, at the same time, due to the deceleration operation, reducing mechanical wear and extend bearing life, improved mechanical reliability sex. (3) the rational use of automatic control technology boiler. Boiler operation, automatic control can improve boiler efficiency, energy conservation. In recent years, automatic control technology and the rapid development of computer control, and more Sheung drum water level automatic control device, automatic control and computer control the combustion process in the oil and gas boilers more general application, for Stoker, some boiler monitoring the use of computer rooms, manual adjustment is also received good results. Boiler automatic control and computer monitoring instruments should be simple, practical principle. (4) promote the use of heat pipe heat exchanger. At present, the domestic part of the boiler flue gas temperature is too high, a large heat losses, reduces the thermal efficiency of the boiler. Can effectively heat pipe heat exchanger flue gas heat recovery boiler, the gas - liquid heat pipe heat exchanger is mounted in the boiler feedwater heating flue, significant energy saving effect, only one heating season investment can be recovered for a heat exchanger. (5) using the condensing heat recovery boiler technology. In conventional boilers, the exhaust gas temperature is generally 160 ~ 250 ℃, water vapor in the flue gas is still in a superheated state, it can not be condensed into liquid water and release latent heat of vaporization. As we all know, the thermal efficiency of the boiler low calorific value fuel is calculated, it does not consider heat loss in a high latent heat of vaporization of the fuel heating value. Thus the thermal efficiency of the conventional boiler generally only 87% to 91%. Waste heat recovery boiler is condensed, to which the exhaust gas temperature is reduced to 50 ~ 70 ℃, full recovery of the latent heat sensible heat of flue gas and water vapor to enhance the thermal efficiency, the condensed water can be recycled. (6) reasonable steam accumulator. The steam accumulator is an energy save type apparatus, steam accumulator principle is that when the boiler load is reduced, the excess steam is fed into the boiler the steam accumulator and the steam under a pressure becomes high pressure saturated water. When the heat load increases, the amount of evaporation in short supply when the boiler, reducing the pressure accumulator, i.e., the high-pressure saturated water is separated into a low pressure saturated steam and water vapor produced by the user for use. Steam accumulator fuel savings typically 5% to 15%. (7) The vacuum deaerator technology. Vacuum deaerator oxygen is an energy save type method. Currently, oxygen supply and drainage method use large industrial boiler thermal oxygen atmosphere. This method of heating water to boiling temperature should at atmospheric pressure, oxygen in the water to drain away. Thermal oxygen atmosphere has two shortcomings. First, the atmospheric pressure boiling temperature, consumes a lot of steam, the boiler to reduce the effective use of heat. A 10t / h boiler feed water heated from 60 deg.] C to 105 ℃, steam consumption about 0.7t / h. Second, because the temperature of the boiler feed water economizer to improve the average water temperature increase, reduce heat economizer temperature, exhaust gas temperature increases, heat losses increase. These two points are the thermal efficiency decreases. And when the vacuum deaerator, the degree of vacuum is maintained at 7.999kPa (60mmHg), as long as the water temperature is heated to 60 deg.] C can achieve the purpose of oxygen. This not only saves steam and reduces exhaust losses, thereby improving the thermal efficiency of the boiler. (8) boiler water treatment technology to promote imports. It is estimated that imports of internal boiler every knot 1mm of scale, the overall thermal efficiency of a decline of 3%, and imports affect the safe operation of the boiler, through effective water treatment technology and cleaning technology, imports of non-boiler scale operation.
Car accessories types of complex processing, such as the interior wall Peng, floor, seats, instrument panels, sound systems, many processes required in a high temperature environment, the temperature becomes optional metrics wind Visteon hot water industry vacuum boiler. It is reported that Dongfeng Visteon existing boiler equipment can not reach the growing production needs, the introduction of fast boiler production of two parties often piezoelectric hot water boiler (CWDR1.8-95 / 70-II) in 2017.
